A high-resolution infrared image has revealed a dust screen obscuring a gas-devouring supermassive black hole in the center of the galaxy NGC 1068, confirming 30-year-old predictions.
Galaxy clusters take eons to collide. Now, astronomers have caught a pair of merging clusters in an in-between stage never seen before.
New research may explain why satellite galaxies align themselves around the Milky Way
Astronomers use cosmic magnifying lenses to peer into the universe's distant past.
A study of 36 dwarf galaxies within a volume of space spanning 13 million light-years show they all have remarkably similar histories despite the vast distances between them.
A combination of simulations and observations indicates that galaxies like the Large Magellanic Cloud control when punier dwarfs plunge into large galaxies.
This week in astronomy pictures: Peer into our galaxy's busy core, watch Clyde's Spot unravel at Jupiter, and see a stunning Hubble photo of a lopsided galaxy.
New distances to two dwarf galaxies with unusually spread-out stars support the idea that these galaxies have little to no dark matter.
New applications of machine learning have enabled astronomers to classify 27 million galaxies and pick out a dozen rare quadruply lensed quasars.
The images from five Brazilian amateur astronomers have captured Hubble-level details in galaxies, laying the ground for future work in understanding their histories. Want to join the fun?
Astronomers have discovered a cluster of galaxies coming together just 770 million years after the Big Bang.
