Astronomers have long thought solar systems follow a simple pattern similar to our own: small, rocky worlds orbit close to ...

Scientists say a nearby red dwarf star hosts a planetary lineup that looks like a mirror image of our own solar system, with rocky worlds bookending a pair of gas-rich planets. Around the star LHS ...

Astronomers have observed a planetary system that challenges current planet formation theories, with a rocky planet that ...

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 closer look at the planets around a star called LHS 1903 may just flip our understanding of how planetary systems form.

In our Solar System, the inner planets (Mercury to Mars) are rocky, and the outer planets (Jupiter to Neptune) are gaseous. This planetary pattern – rock then gas - is consistently observed acro ...

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 ...

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

University of Warwick astronomers, using an ESA telescope, have discovered a planetary system with a distant rocky world that turns our understanding ...

A global team of astronomers, led by the University of Warwick, have used a European Space Agency (ESA) telescope to discover ...

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