This alien planetary system has a Jupiter world 99 times wider than Earth
By Robert Lea published
Astronomers found two planetary systems centered around solar analogs containing mini-Neptune planets and a "super-Jupiter" world 99 times the size of Earth.
NASA identifies 17 exoplanets with possible subsurface oceans
By Conor Feehly published
Internal heating may be able to keep water in liquid form within these exoplanets.
Tiny 14-inch satellite studies 'hot Jupiter' exoplanets evaporating into space
By Keith Cooper published
Hot Jupiters are gas giants so close to their star that the star's heat and radiation can blow the planets' atmosphere away.
That’s no moon! Scientists doubt proposed detection of the 1st exomoons
By Robert Lea published
Scientists aren't sure whether humanity really detected moons outside the solar system.
This 'forbidden' exoplanet is way too massive for its star
By Robert Lea published
"This discovery really drives home the point of just how little we know about the universe. We wouldn’t expect a planet this heavy around such a low-mass star to exist."
Our solar system's planets aren't weird after all. Exoplanets have tilted orbits, too
By Elizabeth Howell published
All solar system planets circle our sun with slightly tilted orbits — and a new study shows even distant planetary systems in quiet neighborhoods have orbital tilts, too.
This rare exoplanet system has 6 'sub-Neptunes' with mathematically perfect orbits
By Sharmila Kuthunur published
A newfound, and impressively well-maintained, planetary system full of sub-Neptunes could reveal why our solar system lacks such a world.
Exoplanet 'haze' makes it harder to identify water on alien worlds. Scientists may have a solution
By Conor Feehly published
Planetary scientists simulate how haze might be obstructing our view of exoplanet's atmospheres, and potentially alien water.
Some exoplanets are shrinking. Here's why
By Sharmila Kuthunur published
Data from NASA's Kepler telescope shows why puffy sub-Neptunes are shrinking to rocky super-Earths.
