Cosmic dust—the tiny particles that help form stars, planets and the chemical building blocks of life—might be much spongier ...

Astronomers and astrochemists reviewed years’ of research to try and resolve a simple question – is cosmic dust porous?

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

The comet, named 3I/ATLAS, is only the third confirmed interstellar object ever seen in our solar system. That means it came ...

NASA's James Webb Space Telescope has delivered new images of Sagittarius B2, the largest star-forming cloud near the Milky ...

Scientists have found a remarkably small yet bright object from the early universe that doesn’t make sense in our existing models of how stars and galaxies formed, even our own Milky Way. That means ...

Across the galaxy, stars are born in immense clouds of gas and dust — stellar nurseries where gravity coaxes material to coalesce and ignite. Around many of these newborn stars, the surrounding gas ...

At just 25, Cecilia Payne-Gaposchkin applied quantum physics to a treasure trove of astronomical observations to show that stars are mostly hydrogen and helium.

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 ...

"We were amazed by the fact that these observatories can detect about 100 black holes just 250 million years after the Big Bang. Such detections would greatly help to constrain black hole formation ...

Hubble’s latest look at Messier 96 reveals a warped spiral galaxy glowing with rings of stellar birth. The new details shed light on how stars emerge and influence their surroundings.
