If you were there, in this infant universe, one second would seem like one second – but from our position, more than 12 billion years into the future, that early time appears to drag.

© Gang Han

The ticking of time isn’t as constant as it seems! Astronomers studying the ancient universe have found that time moved five times more slowly back then. This is called time dilation, and it’s the first time it’s been observed in the early cosmos.

Albert Einstein predicted time dilation over a hundred years ago when he worked out that the expansion of the universe stretches time. Researchers tested the theory using quasars, which are supermassive black holes at the centres of early galaxies.

Quasars emit regular flashes of light, like the ticks of a clock. By observing the flashes over 20 years, the scientists could study how the running of time has changed.

The pair were caught in the act by a volcanic eruption which buried them alive, preserving evidence of their battle. The 125-million-year-old fossil shows a badger-like mammal, called Repenomamus robustus on top of a Psittacosaurus dinosaur (about the size of a large dog), gripping its jaw and biting into its ribs. “The two animals are locked in mortal combat, intimately intertwined,” explained Dr Jordan Mallon, a palaeobiologist who studied the fossil. “It’s among the first evidence to show actual predatory behaviour by a mammal on a dinosaur.”

REBEL BIRDS!

metal spikes are placed on buildings around cities to prevent birds from making nests there – at least that’s the plan! But the clever birds have a better idea, tearing the spikes off and using them to build what the researchers describe as ‘an impregnable fortress’, to keep other birds away from their eggs. In other countries, magpies have been seen making nests from barbed wire and even knitting needles! “It’s like a joke, really,” said Auke-Florian Hiemstra, who is studying the nests. “Even for me as a nest researcher, these are the craziest bird nests I’ve ever seen.” ©

Two brothers from Aberdeenshire in Scotland built these awesome ships themselves – and now they’re hoping to sail them around Antarctica! Ollie and Harry, aged 13 and 11, were inspired by the Ross scientific expedition of 1839-1843. Their boats, named HMS Erebus and HMS Terror after the ships that discovered the Ross Ice Shelf in Antarctica, were launched into the Southern Ocean in July. They are fitted with devices that will collect and send home scientific data, like ocean temperature and acidity, which can help scientists monitor climate change. If all goes to plan, the boats will travel 20,000 km over the next two years. You can follow their journey here: bit.ly/3pUyWI Iq

AN EPIC ADVENTURE

Space is huge, with trillions of planets and moons – yet Earth is the only place where we know life exists.

What do you call a sad spaceship?

A crying saucer!

By Anna Claybourne

...like trees, flowers, insects, dogs – and us humans!

COULD ALIENS EXIST? Life appeared on our planet, so there’s no reason why it couldn’t have arisen in other parts of the universe too. But so far, we have no clear evidence of any alien life existing.

Scientists haven’t found any good evidence of life beyond Earth... yet!

Scientists think life began on Earth about 3.7 billion years ago, when different chemicals combined to form small, simple living cells – the building blocks of living things.

Hello? Are you forgetting someone?

Where am I?!

ALIEN EGG!

IT’S A MYSTERY!

So WHY haven’t we found aliens yet?

Scientists have had several ideas about this…

In 1961, astronomer Frank Drake came up with the Drake equation, which estimates how many intelligent alien societies could exist in our They could be galaxy, the Milky Way. He calculated that there must be sending us messages at least 10,000 alien civilisations right now! advanced enough to send signals across space.

THE CASE FOR: Loads of aliens!

Do aliens lay eggs? No one knows… but if they did, they might look like this!

hite vinegar W (about 150 ml) Caster sugar Green (or other) food colouring

1. Put the egg into the glass, then cover with vinegar. Leave it somewhere safe for two days (bubbles will form on the egg, which will make it float, so you might need to turn it a few times or use a spoon to hold it down).

2. Carefully take the egg out and rinse in cold water. It’s grown and gone all rubbery and see-through!

Answer on page 34 © Department of Energy / Wikim

THE CASE AGAINST: No aliens!

edia Commons

So where are they?

Excuse me! I’m RIGHT HERE! We are alone… as far as we can tell.

ia Commons

Others, such as Professo r Brian Cox, point out that for most of Earth’s history, the only life was microsco pic single cells.

So maybe there IS alien life, but it’s tiny, hard to see, and hasn’t sta rted flying through space or sendin g messages yet.

3. Now place the egg in an empty glass and cover with caster sugar. Leave for 1 day. Now it’s gone all shrivelled!

4. Gently rinse the shrivelled egg in water, put it into a clean glass and cover with water and a good glug of green food colouring and leave it until you're happy with the colour.

You’ve created an ALIEN EGG! An egg is a giant cell. Once you’ve dissolved the eggshell, water can cross the membrane (the ‘skin’ around the egg) by osmosis.

In step 1, water from the vinegar moves into the egg, making it big and bouncy. In step 3, water moves from inside the egg into the concentrated sugar solution, leaving the egg shrivelled and baggy. Then in step 4, the green water moves into the egg, making it big again – and GREEN!

What would aliens be like?

Aliens often appear in sci-fi films, comics and TV shows. But if they do exist, what might they really look like?

Erm… like this, maybe?!

Screen and cartoon aliens are usually cleverer than us, with inventions like intergalactic spaceships or teleportation.

They include… little green (or grey) people – small, spooky-looking aliens with huge eyes.

SCIENCE FACTS!

But if we do ever discover alien life, scientists think it might look more like this!

Microscopic cells – like life on Earth,

alien life would probably include lots of tiny, single-celled living things, similar to our bacteria.

Weird water worms – some scientists think life could exist in deep oceans on other planets or moons. It might be similar to some of our deep-sea creatures, like tube worms or sea slugs.

Purple plants – Earth plants

are green because they contain chlorophyll, a chemical that soaks up sunlight. But alien plants might use different chemicals, making them yellow or purple!

SUPER-SURVIVORS

On Earth, some living things survive in extra-tough conditions – especially animals called tardigrades and bacteria known as extremophiles. They can live in extreme heat or cold or survive high levels of salt or acid.

Some planets and moons have extreme conditions like these, so they could have similar extremophile life forms.

SURVIVING THE COLD

Some extremophiles can survive icy-cold conditions beca use their bodies contain chemica ls that stop them from freezing solid . Try this to see what freezing does to living cells…

Put a piece of fruit, such as a strawberry, tomato or blueberry, in the freezer overnight, take it out, then let it thaw again. Now compare it to fresh fruit. The frozen fruit is mushy because the water in it expanded into ice crystals and ruptured its cells.

I will survive!

OR SOMETHING COMPLETELY DIFFERENT…?

Maybe alien life is even weirder than we think!

Could there be planet-sized plants… or living space soup?

What strange kinds of life can you imagine?

How many of these alien faces can you spot on pages 8 and 9? Check your answers on page 34.

Some scientists think purple plants could grow on other planets.

Getting frozen is not very good for living things!

Some animals on Earth use antifreeze chemicals to stop this happening to them.

Yo u will need

wo small plastic food T containers, roughly the same size and shape Salt Measuring jug Tablespoon Freezer

Ask an adult to help you measure 100 ml of hot tap water into each container. Stir a tablespoon of salt into one of them until it dissolves. Put both containers in the freezer, side by side, and check on them every half hour.

When do they freeze solid? The salty water should take longer to freeze because salt is an antifreeze – it makes water freeze at a lower temperature.

Yoohoo!

Could there be life close to home, in our own Solar system? Scientists think these planets and moons are good places to look:

SPACE SIGNALS

Exoplanets are so far away that it would take thousands of years to travel to them.

But there’s another way: super-fast radio signals.

We’ve sent radio messages into space to tell any intelligent life out there that we exist.

The Arecibo message was sent in 1974. It contained information about the Earth, the solar system, humans and DNA. We also have radio telescopes looking out for any messages aliens might send to us! Only clever aliens could do this, so it’s known as the

Search for ExtraTerrestrial Intelligence (SETI).

AL ANIM S TIC

Cane toads

Not all aliens are in outer space. Some live right here on Earth (because ‘alien’ is another name for a non-native animal!). Our vet Joe Inglis is heading off to the Australian outback to track down this invasive ‘alien’ species.

Cane toads (also called giant neotropical toads) are large amphibians with a long history – the oldest fossilised cane toads are 5 million years old! For most of their time on Earth they lived in the tropical central and southern areas of the Americas. But in the 19th century, they began their alien invasion into other parts of the world, as they were deliberately introduced to try to control pests.

Toads on the road The first alien cane toad invasion happened on Caribbean islands, such as Barbados, Jamaica and Puerto Rico. The toads were deliberately introduced there to try to control beetles that were eating sugar cane (that’s where their name comes from). They have since been taken to many countries around the world, including the Philippines, Papua New Guinea, Japan and Australia.

24 cm

The length of the biggest cane toad ever recorded.

Alien invaders After 102 toads were released in northern Australia in 1935, they quickly spread across Queensland and have now reached as far as Western Australia. As an alien invader, they have caused massive problems to native wildlife, which hasn’t had time to evolve defences against them. They have caused the decline of many reptiles and snakes and largely left the sugar cane beetles alone.

12 whizzpopbang.com

Toad-ally terrifying Measuring 10-15 cm in length, cane toads are one of the largest species of toad in the world. They’re not what most people would call good looking, with dry, warty skin and grumpy-looking faces!

s

Toxic toads To protect themselves against predators, cane toads have evolved some pretty alien defences. Their skin is poisonous and they have glands behind their eyes that ooze out a milky liquid that can kill small animals, and can be very nasty for people too!

Toad tucker Cane toads are hunters and scavengers, catching and eating small mammals, insects, other amphibians and birds. They also love stealing dog and cat food from outside houses and will even tuck into a meal of animal poo if there’s nothing tastier on offer!

Anti-aliens

How do you describe a grumpy toad?

Unhoppy!

Despite their poison defences, some animals such as caiman, opossums and some snakes and eels can eat cane toads safely. Even tiny Australian meat ants are immune to their poison – they can overwhelm a toad and eat it!

200 million The number of cane toads estimated to live in Australia.

Saved by sausages?

In Australia, scientists are trying to protect native animals by training them to avoid the toads using cane toad sausages! When animals like crocodiles and lizards eat the sausages, they get a small dose of cane toad poison, and this puts them off eating the toads.

Change the word PEST to the word TOAD by changing only one letter each time. There are some clues to help you! Check your answers on page 34.

Could there be alien life in our own solar system?

Get out your pencils and pens and design an alien that might live on one of the moons of Jupiter!

Jupiter is a massive planet far outside the Goldilocks zone around our Sun (see page 10 to read more about the Goldilocks zone). It has lots of moons and scientists think it’s possible that life could exist on one or even more of them. They’re trying to find out by sending probes (spaceships without people on board) to investigate.

The European Space Agency (ESA) launched a mission this year called Juice! That stands for Jupiter Icy Moons Explorer. It will study three of Jupiter’s Jupiter has at least 92 moons, after 12 more were confirmed in February 2023.

Below are the names of the 12 biggest ones. Circle any that you find in the grid and then check your answer on page 34. They could be written forwards, backwards, horizontally, vertically or diagonally.

largest moons – Ganymede, Callisto and Europa.

Scientists think they have liquid water oceans deep below their thick, icy crusts. If there is liquid water, there’s a chance there could be life there.

Juice will spend months orbiting Jupiter and flying past the moons, and then finish its mission by orbiting Ganymede. But we won’t have any answers for a while – the journey time to Jupiter is eight years so it will be 2031 before it even arrives!

What’s it called when you have too many aliens?

Extra-extraterrestrials!

NASA is also sending a mission to Jupiter, launching in 2024. It is called Europa Clipper and it will focus on Jupiter’s moon Europa to see if it might be suitable to support life.

GLORIOUS GANYMEDE

Ganymede is the largest moon in our solar system, even bigger than the planet Mercury.

Ganymede’s gravity is less than Earth’s, about the same as our Moon.

Ganymede gets less than one thirtieth the amount of sunlight that Earth does.

Its daytime temperatures at the surface can be as low as -183° C. Ganymede has a faint oxygen atmosphere – but it’s far too thin for us to breathe!

It is likely that Ganymede’s ocean holds more water than all the water on Earth.

If there is alien life on Ganymede, what do you think it will look like? Think about how our bodies are adapted to life on Earth. We have strong bones and muscles so we can move around in Earth’s gravity. We have lungs that can breathe Earth’s atmosphere of mostly nitrogen and oxygen. We have eyes that can see in bright sunlight (and less well at night). But we’re not very good at surviving in extreme cold or heat.

How might an alien be adapted to life in the ocean under the ice on Ganymede?

How would it breathe and eat?

How would it survive the cold,

dark ocean?

How would it sense its environment?

How would it move?

Thin, pointy shapes travel through air more easily with less drag. When astronauts return to Earth, they travel in a ‘re-entry capsule’, which is shaped a bit like a flying saucer! The wide, flat underside keeps the capsule stable and helps to slow it down. When it gets closer to the ground, parachutes create more drag and thrusters add lift to slow the capsule even more for a softer landing!

Once vehicles are in space, it doesn’t matter what shape they are as there is no air to create drag and slow it down. The International Space Station travels at 28,000 km/h, orbiting Earth about every 90 minutes.

Interview with a SCIENCE HERO

In my job I get to... search for another planet like Earth Sara Seager is a professor at Massachusetts Institute of Technology. If you have any questions of your own for Sara, you can contact her on profseager@mit.edu

“

I went to a ‘star party’ with my dad when I was little.

“

I’ve always wondered about life beyond Earth.

”

A movie called E.T. the Extra-Terrestrial was popular when I was a child. It's all about an alien who came to Earth and lived with a normal family – it made me curious about life on other planets. When I was 16, I found out that it was possible to be an astronomer as a job. I told my dad that I was thinking about becoming one and he was concerned. He didn’t know if people could get paid, secure jobs as astronomers. I went to university and studied maths and physics, both of which are important if you want to be an astronomer.

“

”

It wasn’t a party packed with Hollywood celebrities, but one where people who did astronomy as a hobby set up their telescopes and invited everyone along. When I first saw the Moon through the telescope I couldn’t believe my eyes – it was a whole new world! Later, on my first camping trip I saw the dark night sky and an endless number of stars. These memories have stayed with me.

One of my lifelong goals is to find an Earth-like planet.

”

One that is Earth-sized, in an Earth-like orbit around a Sun-sized star. One with a thin atmosphere that has water oceans. One where we can point to a specific star and say, ‘That star has a planet like Earth.’ I love to dream that maybe there’s some life on that planet, looking back at our Earth and our star and saying the same thing. How amazing would that be!

“

NASA is working on a telescope to find Earth twins.

”

We don’t yet have the technology, but NASA’s current research could lead to a telescope that can find planets like Earth in the 2030s or 2040s.

For now, we can study small planets orbiting small red dwarf stars, more like Earth cousins, with the new James Webb Space Telescope. We are still working to study their atmospheres to see if any of them have things in common with Earth.

I’m working on the idea that there' s life in the clouds of Venus.

I do chemistry experiments in a laboratory to find out what kind of biological molecules can survive in sulfuric acid – a nasty chemical that makes up Venusʼs clouds. I research planets beyond our solar system (called exoplanets). We can collect data from space telescopes to find out more about exoplanets’ atmospheres – it’s a good way to understand if they’re similar to Earth or not, and if they might be able to support life. I write computer codes to understand and interpret this data. I’m a teacher, too – I train students to become scientists.

HOW STUFF

WORKS

Radio Telescopes Are we alone in the universe? Radio telescopes might be able to help us find out. They scan the skies, looking for signals from extraterrestrial lifeforms. Here’s how these super-sized alien-detectors work…

1 Radio waves 2

3

Cosmic radio waves are incredibly faint – around one billion billion times weaker than a mobile phone signal – so radio telescopes need massive reflecting dishes to collect and focus these signals. These dishes can be hundreds of metres across to allow them to collect the faintest radio waves.

are a type of electromagnetic energy.

They are emitted by stars, distant galaxies and even giant dust clouds in space (as well as by advanced alien societies – if they’re out there!).

After bouncing off the main reflecting dish, the radio waves are reflected again off a sub reflector above the main one and focussed back down to the centre of the telescope.

4

The focussed beam enters the feed horn, which is a special funnel designed to be exactly the same diameter as the wavelength of radio wave that the scientists want to study, so only these radio waves can pass through.

5

At the bottom of the feed horn is a super-cooled receiver that converts the radio waves bouncing down the feed horn into electronic signals.

6

The reflecting dishes are supported on telescope mounts that allow them to be tilted and turned to focus on different parts of the sky.

The bigger the reflecting dish, the more detail scientists can see when they analyse the radio waves. But really big reflectors are hard to make, so groups of smaller telescopes linked together called arrays are used instead.

The biggest single telescope dish is the whopping 500-metre-wide FAST telescope built in a natural crater in China.

The largest array, called the Square Kilometre Array, is being built in Australia and South Africa. It will have nearly 200 dishes and more than 130,000 radio antennae. When it’s finished in 2028, it will allow scientists to study radio signals that are almost as old as the universe itself – and could pick up distant alien signals, if there are any out there…

carry the electronic signals from the telescope to the control room for processing.

Finally, the signals are analysed by powerful computers which help scientists understand what cosmic events made the signals and what they reveal about stars and galaxies (and one day maybe even aliens!) billions of kilometres away from Earth.

In the control room, receivers and amplifiers boost the signal and separate it out into hundreds or thousands of different signals, each at a different radio frequency.

Crop circles have been

spotted for hundreds of years, but they’re particularly common in Wiltshire, UK. Some people think these intricate patterns must have been created by landing spaceships (but most people think they’re made by humans!).

Weather can create optical illusions that can be mistaken for UFOs. This is a sun dog, where sunlight is refracted by ice crystals in the atmosphere, making it look like there are several Suns (or spacecraft!) in the sky.

Ball lightning is a mysterious phenomenon where a glowing sphere appears close to the ground for a few seconds, hissing and producing an unusual smell. This could be connected to atmospheric gases – or could it be a fleeting visit from aliens?!

2 The Roswell incident of 1947 is a famous UFO (unidentified flying object) story. After metallic debris was found in the desert in New Mexico, USA, some people believed that an alien spacecraft had crashed, but it’s now thought to have been the remains of a high-altitude balloon.

Extraterrestrial sightings aren’t a new thing – there were quite a few ancient UFO-spotters!

Sensational Scientists

By Joanna Tubbs

Carl Sagan Carl Sagan was an astronomer, planetary scientist, cosmologist, astrophysicist, professor and science communicator (phew!) who was fascinated by extraterrestrial life.

CARL EDWARD SAGAN WAS BORN IN BROOKLYN, USA, IN 1934.

When he was a child, curious Carl loved to visit the libraries and museums of New York City. He became interested in stars when he read in a book that the Sun is a nearby star, and that lots of other stars are suns that are very far away from us. When he was four, he visited the World’s Fair exhibition, where he was amazed by an early version of a television and a time capsule.

His brilliant brain was full of questions, and his parents encouraged him to research answers.

Carl never stopped asking ‘why?’

While studying physics, astronomy and astrophysics at university, Carl’s interest in the possibility of life beyond Earth grew and grew.

He’d always loved science fiction and dreamed about aliens visiting Earth – now, he was able to use science to investigate this further. He showed that it’s possible to create the chemical building blocks of life beyond planet Earth.

© NASA/JPL-Caltech

Carl was involved in American space exploration from its very beginning in the 1950s. He briefed the Apollo astronauts before their flights to the Moon and helped to plan missions to Venus, Mars, Jupiter and the outer solar system. He came up with the idea for Voyager I to take a photo of Earth from 3.7 billion miles away to show just how tiny our planet is.

The Pale Blue Dot photo became very famous.

Look again at that dot.

That’s here. That’s home. That’s us.

On it, everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives.

Carl put together several messages that were sent into outer space in the 1970s, including Golden Records that were sent on Voyager I and Voyager II. One of these is now probably the farthest human-made object from Earth. They included: Messages in 55 ancient and modern languages Sounds from Earth, like music, bird song and human laughter Photographs and diagrams of humans and Earth

Find some examples of things included on the Golden Record here:

bit.ly/438i3ro

Make your own Golden Record Think about what you would like to tell aliens about life on Earth today. Write and draw anything you think they should know. You could stick your work onto a circle of card – perhaps an alien will find it one day!

The nature of life on Earth and the search for life elsewhere are two sides of the same question – the search for who we are.

In 1980, Carl presented a TV show about space called Cosmos, which was watched by 500 million people in 60 countries. Carl won many awards before his death in 1996. The Carl Sagan Institute in New York State and the Carl Sagan Centre in California were named after him and are dedicated to continuing his search for life beyond Earth.

Dear Y, What is quantum physics and how does the quantum realm work?

CURIoUS K I DS

From Maisie, aged 11

Quantum physics is the study of matter and energy on a tiny scale. By studying interactions between very small particles, we can gain a much better understanding of the everyday things around us. A quantum is the smallest amount of something.

For example, a photon is a quantum of light energy – knowing its properties and behaviours helps us to make predictions about light. Quantum physics has also helped us make smaller and more powerful computer chips to run satnav systems and mobile phones.

Esme, aged 6, made this brilliantly decorated peg-osau r from the Prehistoric Flying Beasts edition.

To Y, Are humans elements?

From Charlotte, aged 10

An element is a substance which cannot be broken down into other substances. A human might look like a single thing, but you could break one into many different kinds of atoms – representing abou t 60 different elements.

Most are present in tiny amounts, but six make up abou t 99% of a human.

About 10% is hydrogen, made shortly after the Big Bang . You also contain oxygen (65%), carbon (18%), nitrogen (3%), calcium (1.5% ) and phosphorous (1%) – all made in stars! Interestingly, you are 0.0000000 03% gold, which was made in supernovae (exploding stars). We really are made of stardust!

Quantum physics includes some truly mind-bending ideas that can be very hard to imagine. For example, quantum superposition is where quantum particles exist in more than one place at the same time, making parallel universes possible. In the Ant-Man films, ideas from quantum physics are used to create a fictional Q uantum Realm – the space between atoms.

Quantum superposition explains the different timelines and parallel universes, but it’s quantum entanglement (which connects all of space and time) that lets him access any timeline and any universe from a single point – something not yet possible in reality!

Dear Y, When you cut onions, why do your eyes water?

From Ben, aged 9

The lacrimal (say lack-rim-al) glands in your eyelids are constantly making tears to keep your eyes moist and comfortable. But if you cut into an onion, they go into overdrive! That’s because cutting the onion breaks open cells, releasing substances which react with each other to make a chemical that vaporises (turns into a gas). When this gas gets into your eyes it causes a burning feeling and irritates the nerves in your lacrimal glands, so they make LOTS of tears to wash the problem away. Chilling the onions before chopping them can slow down this reaction – or you could try wearing swimming goggles!

SUPER-SURVIVORS

On Earth, some living things survive in extra-tough conditions – especially animals called tardigrades and bacteria known as extremophiles. They can live in extreme heat or cold or survive high levels of salt or acid.

Some planets and moons have extreme conditions like these, so they could have similar extremophile life forms.

Tardigrades are tiny but tough

SCIENCE FICTION!

SURVIVING THE COLD

Some extremophiles can survive icy-cold conditions because their bodies contain chemicals that stop them from freezing solid.

Try this to see what freezing does to living cells…

Put a piece of fruit, such as a strawberry, tomato or blueberry, in the freezer overnight, take it out, then let it thaw again. Now compare it to fresh fruit. The frozen fruit is mushy because the water in it expanded into ice crystals and ruptured its cells.

But if we do ever discover alien life, scientists think it might look more like this!

Microscopic cells – like life on Earth, alien life would probably include lots of tiny, single-celled living things, similar to our bacteria.

Weird water worms – some scientists think life could exist in deep oceans on other planets or moons. It might be similar to some of our deep-sea creatures, like tube worms or sea slugs.

Purple plants – Earth plants are green because they contain chlorophyll, a chemical that soaks up sunlight. But alien plants might use different chemicals, making them yellow or purple!

I will survive!

OR SOMETHING COMPLETELY DIFFERENT…?

Maybe alien life is even weirder than we think!

Could there be planet-sized plants… or living space soup?

Getting frozen is not very good for living things!

Some animals on Earth use antifreeze chemicals to stop this happening to them.

You will need

Two small plastic food containers, roughly the same size and shape Salt Measuring jug Tablespoon Freezer

Ask an adult to help you measure 100 ml of hot tap water into each container. Stir a tablespoon of salt into one of them until it dissolves. Put both containers in the freezer, side by side, and check on them every half hour.

When do they freeze solid? The salty water should take longer to freeze because salt is an antifreeze – it makes water freeze at a lower temperature.

Is it a UFO? This may look like an alien spaceship covered in flashing lights, but it’s a jellyfish!

The Atolla jellyfish lives in oceans around the world. It is found in the mid ocean and even down in the depths of the midnight zone.

Its nickname is the ‘alarm jellyfish’ because when it is attacked, it flashes blue light bioluminescence (say by-oh-loom-in-ess-en-s).

The light is produced by a chemical reaction in its body. This is to startle the attacker and also to attract larger predators to scare the attacker away.
