In each and every day there’s a singular Jupiter is very bright — and will be moment when, all at once, we realize … the the brightest object in the nighttime sky stars.

believed that every human being comes from a star, and that on the descent to life in the physical world, which is governed by time and space, the spiritual beings inhabiting the starry regions bestowed the gift of form to the human body, while the rhythms of the wandering stars, our planets, gifted harmony between the inner organs of the human being.
This way of knowing the human being in relation to the stars existed well into the Middle Ages; it’s evidenced by images depicting the relationship of the signs of the zodiac to the different members of the human being, from the head (Aries) to the feet (Pisces), and the planets in relation to their respective organs (Venus rules kidney; Jupiter rules liver, etc.). There were 48 recognized constellations in the ancient Graeco-Roman world, each described according to the member of the human being to which it was aligned.
It wasn’t until the 16th century that European explorers, traveling to regions of the world unknown to them, began to see stars over lands they had never known, which in turn inspired them to start creating constellations of their own, based on the patterns they made up.
So here’s the rule of thumb: If it looks like what it’s named for, then it might be a constellation that belongs to 16th century ideas, rather than to ancient concepts regarding our relationship to the stars.
Now, even though Jupiter and Saturn are at opposition to the sun this month, they join the lineup of planets that are visible in the morning, beginning with these two low in the southwest, and following on to Mars in the southsouthwest, then brilliant Venus in the east, with Mercury joining the scene low in the east toward the end of the month.
Identify your best stargazing spot by day, avail yourself of a map for familiarizing yourself ahead of time with what you what you want to see, then gather up some stories and head to the stars.
GEAR TO GET YOU STARTED Here are some of my best tips and favorite resources for finding your way around the summer sky in 2020:
First and foremost, a really good, clean star map, like MSU’s Abrams Planetarium Sky Calendar.Just $12/year for one map each month, highlighting the best things to see each week on the calendar side, with a map of the whole night sky on the other side. Available at www.abramsplanetarium.org/SkyCalendar/
A red filter on your flashlight, so you don’t disturb your night vision — or the views of anyone around you. Wrap red cellophane or even a red balloon over a regular white light, but test it out at home first.
A good pair of binoculars can be helpful, ranging in price from $80 to, well … the sky’s the limit. I particularly like the Vixen Optics 2.1x42 SG wide-angle binoculars, available at Enerdyne in Suttons Bay.
Though I much prefer maps to apps, there are a few night sky apps that are really impressive. Just always be sure to plan your viewing before you’re out in the dark, so you’re not wasting too much time looking at a screen instead of looking at the sky: • Star Walk 2, and Star Walk for Kids, which uses GPS to calculate the exact position of the celestial objects from your location. • I also like Distant Suns and Pocket Universe as apps that offer fun features. • The International Space Station Tracker website is fun to check, especially if you want to impress friends and family with predicting its appearance beforehand: www.spotthestation.nasa.gov
The best guide of all to what’s in the northern hemisphere night sky is the Big Dipper, which is overhead every night and can lead you to the North Star, Polaris, while its handle also arcs to the bright star Arcturus, from where you can speed on to the star of abundance, Spica. And then there’s the back of the Lion, which is where the Dipper’s contents would spill if its cup leaked! Following the Dipper’s pointer stars to Polaris allows leads you on to Cepheus the King — and Cassiopeia, his Queen. The Dipper’s position in the horizon can reveal the time of night and even the seasons of the year, plus the sweetest collection of three double stars, which skips along beneath this region of stars, known as the three leaps of the gazelle.
