The “Black Eye Galaxy” is captured in a gorgeous new composite image from the Hubble and James Webb space telescopes.
The Milky Way has a secret history of galaxy mergers that we are only now starting to uncover.
New Hubble data shows definitive evidence of a dwarf galaxy merging with the young Milky Way in the earliest phases of its evolution.
Andromeda has slowed its star-forming rate over the last 40 million years. Scientists think they finally know why.
In this July 6, 2026, image, NASA’s James Webb Space Telescope’s Mid-Infrared Instrument (MIRI) reveals the nearby galaxy Centaurus A, exposing the dusty structures and hidden activity that shape this unusual system. Centaurus A is 11 million light-years away from Earth, relatively close in cosmic terms. Yet, unlike most nearby galaxies, it is very active, […]
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 […]
A slowly rotating stellar halo was the clue to a major and unknown event in the Milky Way’s history that saw the spiral disc flip over by more than 90 degrees.
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).
“We believe that the mechanism that ‘turns on’ these gigantic radio emissions is linked to the formation process of galaxy clusters.”
