Say hello to the newly discovered TRAPPIST-1 system, which is just 39 light-years away and filled with seven Earth-like planets.
The rings of Saturn, Uranus and Neptune may be remnants of smaller planets destroyed long ago by the gas giants' powerful gravity.
And solving that issue could go a long way toward making our planetary neighbor habitable.

It's a bird, it's a plane, it's a supermoon! Aside from being bigger and brighter than a regular moon, does a supermoon affect anything on Earth?
The sun's atmosphere is actually hotter than its surface, even though you'd assume the surface is what generates all that heat. How does that work?
Saturn's largest moon Titan is the only other celestial body we know of that has liquid lakes on its surface. NASA has just captured some amazing footage of clouds.
The space telescope's ultraviolet observations come days before the Juno space probe will arrive to orbit the gas giant's polar regions.

The moon has seen a lot in its 4.5 million years of life, and this detailed geologic map serves as testament.
Astronomers used Hubble's full range of imaging to dissect wild 'fireworks' happening in two nearby young planetary nebulas.
Star-gazers gasped when they saw how much Betelgeuse dimmed in 2019 and the reason wasn't clear. Even though it's back up to full strength, how long will it be before it explodes? We haven't seen a supernova in over 400 years.
Even if you've never looked through a telescope, you've probably seen Vega, one of the brightest stars in our galaxy. In fact, thousands of years ago, Vega was our North Pole star, and will be again in the future.

Winter is the perfect time to look for Orion's Belt in the Northern Hemisphere. If you're new to stargazing, we'll show you how to find it.
You might call it a Christmas miracle. Jupiter and Saturn will align so closely they may look like a double planet. The last time we saw this was in 1226.
The Quadrantids are a short but powerful meteor shower that shows up in early January. How can you glimpse it?
A magnetar is a neutron star with a super-strong magnetic field. Astronomers consider them among the scariest objects in the universe, but why?
