This week astronomers have announced the completion of the largest 3D map of galaxies across the cosmos, plus exquisite radio observations show what happens when a stellar intruder interrupts planet formation.
Supernovae that carved out the Local Bubble, a cavity around the Sun, have also triggered star formation at the bubble's edges.
A stream of stars scattered across 15 degrees of sky was once part of a globular cluster torn apart by our galaxy’s gravity. The stars represent some of the oldest in the Milky Way.
New research may explain why satellite galaxies align themselves around the Milky Way
Astronomers have observed an object like ‘Oumuamua — but unlike the first known interstellar visitor, this one is in the solar system.
The release of the Astro2020 Decadal Survey is imminent, in which four concepts compete to become NASA’s next flagship mission. From exo-Earths to X-rays, what will the future hold?
Astronomers witness the unfurling of a black hole-powered mushroom cloud, a baby super-Jupiter, and a magnetic "tunnel" around the solar system.
The United Nations' Office of Outer Space Affairs is considering issues of light pollution spanning from streetlights to satellites.
What seemed a lucky break — the discovery of a gamma-ray burst in the most distant known galaxy — might instead be the flash of passing space debris. As satellites fill low-Earth orbit, such events might become common.
Astronomers use cosmic magnifying lenses to peer into the universe's distant past.
Some 10 million years ago, dying stars cleared a giant cavity in space and ultimately inspired a new generation of star formation.
