The stars have spoken. As scientists discover oddly shaped stellar movement patterns in the Milky Way disk, they uncover a turbulent past that included a near collision with another familiar galaxy.
The monster galaxy COSMOS-AzTEC-1 is spitting out stars at an abnormally frenzied pace. Scientists take a closer look using ALMA in Chile, finding that the gas clouds within are startlingly unstable.
Once upon a time, the Milky Way died. It may have been several billions of years ago, but the stars in the sky paint a picture of the galaxy’s tumultuous history that has huge implications in galaxy evolution.
The earliest galaxies in the entire universe are lying just outside the Milky Way, providing windows to an ancient time billions of years ago. A new study explains the formation of galaxies during the universe’s so-called cosmic dark ages.
Eta Carinae, one of the galaxy's most dazzling stellar objects, exploded in a massive blast 170 years ago. The cause of the blast remain largely a mystery, but in a new study, scientists find clues of the 1840s explosion.
South Africa's powerful new radio telescope MeerKAT captured the Milky Way's center with extraordinary detail and unparalleled clarity. It's the clearest ever view of its heart, which could answer so many questions astronomers have on the Milky Way and beyond.
Who knew the universe is actually very greasy? A new study reveals that the Milky Way's interstellar dust is rich in grease-like carbon matter, which is also extremely toxic.
If there is extraterrestrial life out in the cosmos, Breakthrough Listen's upgraded Parkes telescope will find it. The SETI initiative begins the hunt, sifting through billions of stars in hopes of spotting signs of aliens.
The Hubble Space Telescope captured images of a dead disk galaxy, which challenges previously held theories about the evolution of galaxies.
NASA revealed a stunning image of a Crab Nebula, a remnant of a supernova explosion. The image was from combined data of many different instruments.
Like creamer being stirred in coffee, hot gas swirls around in this galaxy cluster for millions of years.
In the outermost reaches of our galaxy known as the halo lies a record breaking brown dwarf that have the purest composition and highest mass yet known.
A team of scientists from Japan has found something strange in space, specifically a supersonic space cloud traveling the Milky Way.
A mysterious "void" appears to be pushing the Milky Way galaxy through the Universe at 2-million km/h, as if fleeing from what appears to be an enigmatic "dead zone."
