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

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

An exoplanetary system about 116 light-years from Earth could flip the script on how planets form, according to researchers ...

Astronomers have found a compact solar system whose planets line up in a way that, according to current models, should not be possible. Around the small star LHS 1903, a dense rocky world orbits on ...

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 ...

By Will Dunham WASHINGTON, Feb 14 (Reuters) - Astronomers have observed a planetary system that challenges current planet ...

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

An interstellar comet racing through our solar system released methanol, methane and cyanide, NASA says. Could these life linked molecules hint at how worlds across the cosmos are seeded?

"Energy transition" is a very common term but has no official definition. This article reviews the four key theories and what ...

The planetary system, located 120 light-years away, features four worlds orbiting a red dwarf star and challenges classical formation schemes.

A massive star 2.5 million light-years away simply vanished — and astronomers now know why. Instead of exploding in a supernova, it quietly collapsed into a black hole, shedding its outer layers in a ...
