exoplanet

The possible Saturn-sized planet was detected in the galaxy Messier 51, 28 million light-years from Earth, making it the most distant exoplanet ever found.

Geochemistry study suggests the interiors of some exoplanets are very similar to that of Earth.

The exoplanet is 110 light-years from Earth and was discovered by NASA's Kepler spacecraft in 2015.

U.S. scientists found the iron meteorite—first discovered in the 1950s—contained a mineral that normally forms through the smelting of iron.

The planet, HR 5183 b, is three times the size of Jupiter and slingshots around its star along an egg-shaped orbit.

The exoplanet orbits a star that sits just six light-years away from Earth.

The enormous object sits just 20 light-years from Earth.

A stable climate could be key to hosting life.

A year on these planets flies by, lasting between five and 10 Earth days.

We think of stars as individual things, but that's not really the case—only a slim majority of solar systems in the universe contain just one star.

Terrestrial life is intimately influenced by the tilt of Earth's axis, so it shouldn't surprise us if the same is true elsewhere.

The object is more than 200 times farther away from its stars than Earth is from the sun.

Clouds can't form in the atmosphere of WASP-96b.

NASA asked kids to submit their depictions of exoplanets for the satellite's launch.

The distant planet may have an ideal temperature for liquid water.

The treasure trove joins thousands of other exoplanets previously discovered.

NASA's 2019 budget proposal calls for the telescope to be canceled "due to its significant cost and higher priorities within NASA."

(Methane + carbon dioxide) - carbon monoxide = aliens?

The strange planet upends current theories about these distant worlds.

Scientists didn't find aliens in 2017, but here's what they did find.

Super-thick atmospheres could be enough to cocoon planets from the rough neighborhood of these stars.

A key version of an element could be a sign of life elsewhere.

Scientists were investigating K2-18b when they came across another planet hiding behind it.

The device will look for stars like our own sun and examine planets similar to Earth.

It's unlike anything else scientists have seen.

It's easier to study planets that are closer to their suns, but how close can you get before it becomes too hot and dry for life to survive?

But don't book your tickets yet—this place is definitely too hot to handle.

Whether you're looking for a tropical getaway or a chance to sit by the ocean, this project has you covered.

It even orbits a star that doesn't spit out deadly rays on a regular basis—cozy!

It's about the size of 13 Jupiters smooshed together, which means that for a planet, it's really, really big.
