The star-forming region called Sagittarius B2 contains half of the galactic center's stars, yet only 10% of the gas.

A surprising new study reveals that the first stars appeared in a pre-heated universe, challenging earlier ideas about early cosmic conditions.

Star formation is a fundamental physical process in our universe. Stars light up the cosmos, and give rise to planets, some ...

For decades, astronomers have wondered what the very first stars in the universe were like. These stars formed new chemical elements, which enriched the universe and allowed the next generations of ...

The newborn planetary system appears to be emerging 1,300 light-years away around a baby star known as HOPS-315. Planet-forming materials were first identified using NASA's James Webb Space Telescope.

In the cold dark of interstellar space, a rogue planet is defying expectations by growing at a staggering rate. Recent ...

Some classes of stars create light elements, such as oxygen and silicon; others also craft heavier ones, such as iron and ...

Astronomers have observed a massive growth rate in a free-floating rogue planet that’s gobbling up gas and dust at a record rate of 6.6 billion tons per second.

Webb's Mid-Infrared Instrument (MIRI), which shows thermal light, collected observations of the planet that allowed the team ...

Chemistry in the first 50 million to 100 million years after the Big Bang may have been more active than we expected. This article was originally published at The Conversation. The publication ...
