GRB 230906A, a short gamma-ray burst first detected in 2023, points to a faint galaxy embedded within a long stream of torn ...

Nearly all stars are found inside or around galaxies, because that's where the conditions are right for stars to form. Within galaxies, stars form inside cold, dense molecular gas clouds like those ...

Redefining How Galaxies Are Classified For decades, astronomers have classified galaxies into two main types: blue galaxies, which are young and teeming with star formation, and red galaxies, ...

A recently detected flash of energy appears to have emanated from the wreckage of colliding galaxies, according to an international team of astronomers led by Penn State scientists. The burst, known ...

Scientists have uncovered evidence that our Sun may have traveled across the Milky Way as part of a massive migration of ...

A powerful "gamma-ray burst" has been seen exploding from merging neutron stars hidden within a previously unknown mini-galaxy leftover from an ancient cosmic crash. The "collision within a collision" ...

The study of galaxies and their star formation processes remains a cornerstone of modern astrophysics. Galaxies are the fundamental building blocks of the Universe, each hosting a complex interplay of ...

This article was originally published at The Conversation. The publication contributed the article to Space.com's Expert Voices: Op-Ed & Insights. If you look across space with a telescope, you'll see ...

From your place inside the Milky Way, you are living within a galaxy that keeps a detailed chemical diary. Every star holds clues about when it formed and what the galaxy was like at the time. Over ...

Astronomers have used the James Webb Space Telescope to peer inside the heart of spiral galaxies, where young stars carve out glowing paths. The space observatory, named after a North Carolina native, ...

Scientists traced star-forming gas clouds in a nearby lenticular galaxy, NGC 1387, offering new insight into early-type ...

New findings from a large survey of galaxies suggest that star formation is largely driven by the supply of raw materials, rather than by galactic mergers that trigger sudden bursts of star formation.
