Gemini North captures sprawling aftermath of head-on colllision between a pair of galaxies. The Gemini North telescope, one half of the International Gemini Observatory, operated by NSF’s NOIRLab, captured a dazzling image of UGC12914 and UGC312915, which are nicknamed the Taffy Galaxies...

Astronomers have discovered a large reservoir of hot gas in the still-forming galaxy cluster around the Spiderweb galaxy — the most distant detection of such hot gas yet. Galaxy clusters are some of the largest objects known in the Universe and this result further reveals just how early these structures begin to form.

Using the Atacama Large Millimete...

Researchers model how elements move across star-forming regions. Much like how wind plays a key role in life on Earth by sweeping seeds, pollen and more from one place to another, galactic winds — high-powered streams of charged particles and gases — can change the chemical makeup of the host galaxies they form in, simply by blowing in a specific direction.

Using observations made by NASA’s Chandra X-ray Observatory, a new study details how these energetic winds, once released from the center of a galaxy, directly influence the temperature and metal distribution of the rest of the region.

“Galactic winds are a large part of galaxy evolution in general,” said Sebastian Lopez, lead author of the study and a graduate...

Scientists believe the gamma-ray emission, which lasted over 300 seconds, is the birth cry of a black hole, formed as the core of a massive and rapidly spinning star collapses under its own weight.

On October 9, 2022, an intense pulse of gamma-ray radiation swept through our solar system, overwhelming gamma-ray detectors on numerous orbiting satellites, and sending astronomers on a chase to study the event using the most powerful telescopes in the world.

The new source, dubbed GRB 221009A for its discovery date, turned out to be the brightest gamma-ray burst (GRB) ever recorded.

In a new study that appears today in the Astrophysical Journal Letters, observations of GRB 221009A spanning from radio waves to gamma-rays, including critica...
