Since the 1990s, scientists have discovered approximately 6,100 planets outside our solar system, called exoplanets.

An exoplanetary system about 116 light-years from Earth could flip the script on how planets form, according to researchers who discovered it using telescopes from NASA and the European Space Agency, ...

An inside-out planetary system around the star LHS 1903 is turning everything that astronomers know about planet formation upside down.

Astronomers have uncovered a distant planetary system that flips a long-standing rule of planet formation on its head. Around the small red dwarf star LHS 1903, scientists expected to find rocky ...

Since the 1990s, astronomers have found a handful of other dwarf planets in the belt, such as Eris and Sedna, along with ...

A record-breaking gravitational wave signal let scientists "listen" to a distant black hole merger and put Einstein's gravity to its toughest test yet.

In a paper to be published in the Planetary Science Journal, scientists from SETI Institute, Southwest Research Institute, Caltech and the Observatoire de Paris argue that Saturn’s largest moon is not ...

A planetary system 116 light-years from Earth has a peculiar pattern. It could flip the script on how planets form, ...

Surprised astronomers said Thursday they have discovered a star with planets in a bizarre order that defies scientific expectations -- and suggests these faraway worlds formed in a manner never seen ...

Their observations of a faint, cool M-dwarf star called LHS 1903 revealed a system with a rocky world at its outer edge. LHS ...

“It’s all I ever wanted to do,” said Connolly, founding chair and professor in the Department of Geology within the School of Earth & Environment and a research associate in the Department of Earth ...

Even when Earth was locked in its most extreme deep freeze, the planet’s climate may not have been as silent and still as once believed. New research from ancient Scottish rocks reveals that during ...
