New Hubble data shows definitive evidence of a dwarf galaxy merging with the young Milky Way in the earliest phases of its evolution.
Since their discovery by NASA’s James Webb Space Telescope in 2022, little red dots (LRDs) have been the subject of great interest to astronomers. Understanding the nature of these extremely distant, compact red sources has been a puzzling scientific endeavor. One popular theory is that little red dots are supermassive black holes known as active […]
NASA’s Hubble finds that star formation in the Andromeda galaxy has undergone a 500-million-year decline.
This Hubble image features spiral galaxy NGC 4654, located 72 million light-years away in the constellation Virgo (the Maiden).
Using Hubble, astronomers have discovered that the only known “helium nova” in the Milky Way is riddling our galaxy with cosmic bullets travelling at 20 million mph.
Astronomers using archival data from Hubble and supportive observations from Webb have located their first stellar-mass black hole in the star cluster Omega Centauri.
Red, white, and blue stars glitter like a sparkler being waved on a dark night in this new image from NASA’s Hubble Space Telescope.
Blue and white stars shine brightly against crimson gas in this image from NASA’s Hubble Space Telescope.
More than 500,000 stars blaze red, white, and blue in this NASA Hubble image of the globular cluster Messier 3 (M3).
The subject of today’s NASA/ESA Hubble Space Telescope image is an ancient inhabitant of our galaxy. This sparkling scene features a globular cluster: a collection of tens of thousands to millions of stars, all tightly bound together under the influence of gravity. There are more than 150 globular clusters in our galaxy, though there may be […]
