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 known structure of galactic origin.   The discovery highlights our poor understanding of these colossi, and what drives their … Read more

Cosmic robbery: New study explains how smaller galaxies lose their dark matter

Large galaxies may steal dark matter from smaller galaxies they nearly collide with, new research suggests.  Scientists from the University of California, Irvine and Pomona College used computer models to simulate the evolution of a corner of the universe about 60 million light-years across. The new computer models, which weren’t designed to do so, created … Read more

Behold, The Most Accurate Virtual Simulation of Our Universe to Date

In the Cosmic Calendar, which maps the chronology of the Universe across a single Earth year, modern humans don’t appear until the very last minute of December 31. Everything we understand about the evolution of the Universe, we’ve had to piece together. We simply haven’t been around for pretty much any of the 13.7 billion-year … Read more

Major African Radio Telescope Will Help to Image Black Holes

Astronomers across Africa and Europe have reacted with delight to news that Africa’s first millimetre-range radio telescope is to be built. The Africa Millimetre Telescope will fill a gap in the coverage of the Event Horizon Telescope (EHT), a global network of telescopes that can receive and analyse radio waves of around 1 millimetre in … Read more

How Many Galaxies Are There?

Galaxies are vast collections of stars that populate our universe. But how many galaxies are there? Counting them seems like an impossible task. Sheer numbers is one problem — once the count gets into the billions, it takes a while to do the addition. Another problem is the limitation of our instruments. To get the … Read more

Map of the universe: Largest ever survey covers 8 million galaxies

Astrophysicists hope a map created by the Dark Energy Spectroscopic Instrument will help answer questions about the expansion of the universe Space 13 January 2022 By Jason Arunn Murugesu The telescope where DESI is mounted at Kitt Peak National Observatory, Arizona KPNO/NOIRLab/NSF/AURA/P.​ Marenfeld The largest 3D map of the universe has been created by a … Read more

This map of distant galaxies could help untangle the mystery of dark energy | Science

A new cosmic survey project known as the Dark Energy Spectroscopic Instrument (DESI) today released its first results: the most detailed 3D map of the universe to date, which shows the locations of 400,000 galaxies up to distances of 10 billion light-years. The map is the fruit of the project’s first 7 months of operation. … Read more
