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

Planets are born, and they can also "die." So what's the lifespan of a typical planet?

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

Astronomers have found a distant world that challenges planetary formation theory, with a rocky planet where gas giants should be.

The planets around a nearby star seem to be in the wrong order, hinting that they formed through a different mechanism than ...

A new study led by UNLV scientists sheds light on how planets, including Earth, formed in our galaxy – and why the life and death of nearby stars are an important piece of the puzzle. In a paper ...

Astronomers say a newly discovered solar system about 116 light years from Earth is challenging long held ideas about how planets form.According to CNN, researchers using telescopes from NASA ...

Relatedly, astronomers may have just pushed the upper size limit of what counts as a planet.

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