Last month, the European Space Agency (ESA) released a huge dataset from its space telescope Euclid. The release featured three deep-field mosaics glittering with 380,000 galaxies and hundreds of ...

Astronomers have identified a possible new example of one of the universe's strangest galaxy types: galaxies that appear to contain little or no dark matter. The newly studied pair, FCC 224 and FCC ...

Understanding how galaxies grow has long stood as one of astronomy’s core challenges. Over time, scientists have gathered evidence that galaxy mergers matter. When two galaxies move close, gravity can ...

When it comes to the Milky Way and Andromeda galaxies, there’s a whole “will they or won’t they” thing going on. In 2012 scientists published their results of Hubble Space Telescope observations ...

A whole universe of hidden galaxies lies just beyond what the eye can see. Thanks to a new generation of space telescopes, astronomers are now revealing these distant, dim worlds—some no bigger than a ...

Galaxies like the Milky Way grow by merging with smaller galaxies over billions of years, unlike dwarf galaxies, which have long been thought to lack the heft to attract mass and grow in the same way.

This image shows an area of Euclid’s Deep Field South. The area is zoomed in 16 times compared to the large mosaic. ESA/Euclid/Euclid Consortium/NASA, image processing by J.-C. Cuillandre, E. Bertin, ...

Our understanding of the universe begins with the Big Bang, a moment in time where the universe began expanding into what we see around us now. Big Bang nucleosynthesis describes how only the lightest ...

Astronomers have discovered a ghostly, million-light-year-long bridge of stars connecting two massive galaxies within the Abell 3667 cluster, 700 million light-years away. This glowing thread of ...

Scientists say it's the earliest galaxy seen doing this (so far). When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Astronomers have caught an ...
