Stellar space There is some pretty strange stuff in space. Things that not even the strangest science fiction stories have dreamed. Some things are just so weird that even astrophysicists don’t know what they are, while others just leave you completely baffled!

Extra inches
spherical liquids
Want to add a few inches to your height? Pay a visit to outer space! All human beings are about two inches taller in space. The human spine is like a giant spring that is being held down by gravity as we walk around on Earth. When in space, the force gravity exerts on our body is no longer there, so the spine naturally stretches out like a spring in a process called spinal elongation. The bad news? Back on Earth, they shrink back down to normal height, because they’re not really “growing,” they’re just stretching out. Unfortunately, the extra height can bring complications, which may include backache and nerve problems.
Here on Earth, liquids tend to flow downwards and take the shape of whatever container they’re put in. But something as simple as a liquid is completely different in space! It is because of the zero-gravity vacuum of space that liquids shape themselves into perfectly round spheres. This is because of a phenomenon called surface tension that causes water to form as a horizontal surface on Earth causes liquids to form spheres in space.

Diamond star Twinkling up and above in the sky is a diamond star of 10 billion trillion trillion carats, completely outclassing even the largest diamond on Earth. The huge cosmic diamond — technically known as BPM 37093 — is actually a crystallized white dwarf. A white dwarf is the hot core of a star, left over after the star uses up its nuclear fuel and dies. In other words, a diamond star is the burned out corpse of a star! The white dwarf is not only radiant but also rings like a gigantic gong, undergoing constant pulsations. Astronomers expect the Sun to become a white dwarf when it dies 5 billion years from now. Some two billion years after that, the Sun’s ember core will crystallize as well, leaving a giant diamond in the centre of the solar system.

Why couldn’t the astronaut book a room on the moon? Because it was full.
Quasars
How do astronauts serve dinner?
Lasting footprints
On flying saucers. What do you think of that new restaurant on the moon? The food’s great but it has no atmosphere. How many astronomers does it take to change a light bulb? None, astronomers aren’t scared of the dark. Why does NASA believe there might be life on Mars? The CD player was stolen from their Mars rover. When do astronauts eat their lunch?
Due to the absence of air and wind on the moon, all astronaut footprints last for millions of years, longer than the most permanent structures on Earth. As long as a meteor or any other space particle does not hit the moon, any impressions made into its surface will virtually last forever. Now we know why Neil Armstrong’s left boot print, the one that made history, is still up there, most likely as fresh and new as when it was made over 42 years ago.
At launch time. Which chocolate bars do you eat in space?
Short for “quasi-stellar radio source, many astronomers believe that quasars are the most distant objects yet detected in the universe. Quasars are believed to produce their energy from massive black holes in the center of the galaxies in which the quasars are located. Due to their great distance from Earth, energy from quasars takes billions of years to reach the Earth’s atmosphere. For this reason, the study of quasars can provide astronomers with information about the early stages of the universe. Perhaps more interesting, Quasars give off enormous amounts of energy — they can be a trillion times brighter than the Sun!

How to make
Bow wreath Here is how to make a beautiful wreath using paper and ribbon.
Materials needed: • • • •
Craft Wire (12-inches or more) Hot glue gun Pastel paper (printer paper) Ribbon (any width)
Instructions: With the pastel paper, cut eight inch strips on each piece of paper. Then fold each strip to a 4 inch strip. You will have several four inch strips of different colours when you will be finished. Hot glue the end of the strips as
you will be doing several bows to do the wreath. With the wire, form a 12 inch (or larger) circle. Take each bow and starting at the top of the circle, hot glue each bow to the wire form. Make sure you are wearing protective gloves using hot glue. At the back of each bow, put a strip of paper so that the hot glue is not detected at the back. Use iridescent pink curly ribbon and wrap it around the wreath at different points and then make a bow at the top. You can use any type of ribbon you have to make the bow.
