When the Magellanic Cloud galaxies get close, star formation peaks
Like two great songwriters working side by side and inspiring each other to create their best work, the Magellanic Clouds spawn new stars every time the two galaxies meet.
Visible to the naked eye but best seen from the…
Anomalous Fast Radio Bursts from other galaxies could help astronomers study dark matter
The science of Fast Radio Bursts (FRBs), anomalous flashes of radio signals appearing in the sky roughly once per minute, just got a little clearer — if also a little weirder.A new study appearing Wednesday in the journal Nature has…
With relief, researchers find an explanation for dark-matter-poor galaxies
Enlarge / The slightly hazy, light patch in the middle of the image is the DF2 galaxy, so diffuse that other galaxies are clearly visible behind it.
The first…
The Biggest Galaxy Ever Found Has Just Been Discovered, And It Will Break Your Brain
Astronomers have just found an absolute monster of a galaxy.Lurking some 3 billion light-years away, Alcyoneus is a giant radio galaxy reaching 5 megaparsecs into space. That's 16.3 million light-years long, and constitutes the largest…

Take a Look at The Largest And Most Detailed 3D Map of The Universe Ever Made
The Dark Energy Spectroscopic Instrument (DESI), currently pointed at the skies from its home in the Nicholas U. Mayall Telescope at the Kitt Peak National Observatory in Arizona, is tasked with charting the expansion of space,…
Astronomers Discover a Strange Galaxy Without Dark Matter
Three years ago, Filippo Fraternali and his colleagues spotted a half dozen mysteriously diffuse galaxies, which looked like sprawling cities of stars and gas. But unlike almost every other galaxy ever seen—including our own Milky…
