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 ...

Oftentimes, we think of space as an endless, mostly empty vacuum, a silent backdrop where planets, stars, and galaxies play out their dance. We also think of time as something separate, a steady ...

"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 ...

The comet, named 3I/ATLAS, is only the third confirmed interstellar object ever seen in our solar system. That means it came from another star system entirely. At first, some speculated it could be an ...
