All of the planets in the solar system are named for Greek gods, except Earth. So where did the name come from?
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?
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 annual Leonid meteor shower is back, and peaks in the early-morning hours of November 17. It's made up of tiny bits of debris from the comet Tempel-Tuttle. Here's how to see it.
Every autumn, Earth passes through a stream of debris left by Halley's comet, resulting in nighttime meteor showers in mid-October. Best time this year is Oct. 21-22.
It's a celestial gift in the middle of August. Just look up for a spectacular sight.
In 1953, CalTech geochemist Clair Patterson came up with an estimate for Earth's age that still holds today.
Uranus is the seventh planet from the sun and sits on an axial plane tilted at a jaw-dropping 97.7-degree angle. And yes, Uranus does actually stink.
The moon has seen a lot in its 4.5 million years of life, and a detailed new geologic map serves as testament.
Every April, the Lyrid meteor shower fills the sky with shooting stars. Here's how to see them.
Saturn is the sixth planet from the sun and the second largest planet in the solar system. It has an amazing ring system and 82 moons! And did we mention that it's an oblong world that appears squished looking?
NASA and the European Space Agency's new Solar Orbiter will travel as close as 26 million miles to the sun to get the first glimpses of its north and south poles.
Neptune is the eighth planet from the sun, and one of the coldest. It also has supersonic winds that are the fastest in the solar system.
The Geminid meteor shower is one of the year's stronger displays in terms of number and size of meteors. When's the best time to see it?
The atmospheric pressure is crushingly extreme on Venus, and lead would melt into a puddle on its surface. But as hellish as this place sounds, it actually has a lot in common with Earth.
Jupiter is the largest planet in the solar system. Big as it is though, next to the sun, Jupiter looks puny.
As the search for Planet Nine wears on, and astronomers have yet to get so much as a glimpse of it, researchers are pondering what else the object might be.

NASA just named a rolling rock on Mars after — who else — the Rolling Stones.
Did you know that a moon can leave its orbit around a large planet and go out on its own?
Researchers at the Zwicky Transient Facility have found an asteroid in Earth's orbit. And this one has the shortest year yet.
Scientists recently found 12 more moons revolving around Jupiter, bringing its total to 79. Why does Jupiter have so many darn moons? Is there any advantage to that?
