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.
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.
NASA asked kids to submit their depictions of exoplanets for the satellite's launch.
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?
Scientists didn't find aliens in 2017, but here's what they did find.
A key version of an element could be a sign of life elsewhere.
The device will look for stars like our own sun and examine planets similar to Earth.
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.
