Learn why only 14 out of over 6,000 exoplanets orbit two stars, and how Einstein’s general theory of relativity may be to blame.

For decades, planet formation existed mostly in theory and simulations. Now, astronomers have captured direct evidence ...

New simulations suggest Jupiter holds far more water than once thought, reshaping ideas about how the largest planet formed.

A young star called V1298 Tau is giving astronomers a front-row seat to the birth of the galaxy’s most common planets. Four ...

V1298 Tau links swollen young worlds to the compact planets that astronomers keep finding, and its timing signals made that connection measurable. Future transit-timing and atmospheric observations ...

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 ...

The origin of super-Earths and sub-Neptunes has been revealed in a system of four young planets that are dramatically losing ...

CONFIDENCE IN HAPPENING YESTERDAY. NEW MEXICO STATE UNIVERSITY ASTRONOMER RECENTLY SAW SOMETHING UNUSUAL DURING HIS RESEARCH OF SPACE, AND IT COULD HELP US UNDERSTAND HOW PLANETS FORM. VLADIMIR LYRA ...

Hot Jupiters rank among the strangest planets astronomers have ever found. They are gas giants as massive as Jupiter, yet they race around their stars in just a few days. Since the first such world ...

How did a planet this big form around a star this small? An international team of astronomers, including researchers from the University of Liège and collaborators in UK, Chile, the USA, and Europe, ...
