Hey, Sky Fans!
Did you know you can see Jupiter’s four giant “Galilean” moons from your own home? It’s true! All you need is some clear skies toward the south tonight (and for the next few months) and a pair of regular, every-day binoculars.
In even the 35-year-old department store ones like I have, you can see them as four infinitely tiny dots lined up along Jupiter’s equator! Just head out tonight, look for Jupiter along the southern sky, and see what you can see.
Saturn’s there, too, but it’s twice as far away, and… its moons are much harder to see.
In this super-zoomed-in view from later tonight, from left to right, it’s:
(your view probably won’t be like this)
Callisto: The “Tons of Craters!” one.
Jupiter: The “A Thousand Earths’ll Fit Inside!” one.
Io: The “Sulfur Volcanoes!” one
Ganymede: The “Bigger Than The Planet Mercury” one
Europa: The “Water Ice Covering Its Surface” one.
That’s four of the solar system’s six biggest moons. Can you name the other two?
I hope you’ll take a look. Clear skies, everyone!
