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.
The CHIME telescope has released its first catalog with 492 unique sources of fast radio bursts, the brief flashes of radio waves that have been intriguing astronomers over the past decade.
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.
Astronomers thought a super-Earth might orbit nearby Barnard's star. But a new study disputes that claim, arguing that stellar activity might be masquerading as the planetary signal.
Astronomers have discovered that a satellite of the Milky Way has left a "wake" in the dark matter halo that surrounds our galaxy.
The Crab Nebula pulsar has sporadically bursted for decades. Now, astronomers have found these mysterious bursts release even more energy than thought.
New applications of machine learning have enabled astronomers to classify 27 million galaxies and pick out a dozen rare quadruply lensed quasars.
New analysis shows that Comet 2I/Borisov, which zipped nearest the Sun in late 2019, was unlike any comet we’ve seen before.
New maps of the Milky Way suggest the Local Arm that we call home is longer than expected — now upgraded to a major spiral feature (but not quite an arm).
This week in pictures: Astronomers have watched auroral storms at Jupiter, imaged strands of the cosmic web, and seen stellar fireworks off the sword of Orion.
A new study suggests that by 3 billion years ago, most of the Red Planet’s water was locked away in minerals, and it has stayed there ever since.
