PARIS, France - 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 ...

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 ...

(March 21-April 19) ★★★ A boss, parent or someone in a position of authority might catch you off guard today or surprise you ...

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

Typically, from what astronomers have gathered thus far, star systems follow a tidy logic: small, rocky worlds huddle close to the warmth of their star, while massive gas giants bloat up in the colder ...

A dazzling new Hubble image peels back the layers of the mysterious Egg Nebula, a rare and fleeting phase in a Sun-like star’s death just 1,000 light-years away. Hidden inside a dense cocoon of dust, ...

A small red dwarf star in the Milky Way has drawn attention after astronomers mapped four closely orbiting planets around it.

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 ...

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

"This strange disorder makes it a unique inside-out system," study lead author Thomas Wilson, physics professor from the University of Warwick, said in a statement. "Rocky planets don't usually form ...
