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 ...

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 ...

Neutron star collision in merging galaxies reveals how cosmic destruction forges heavy elements like gold, offering clues to the universe's chemical evolution. (Nanowerk News) A recently detected ...

In this combination of images from NASA/ESA shows three future scenarios for Milky Way & Andromeda encounter. Top left: Galaxies bypass at 1 million light-year separation. Top right: At 500,000 ...

Something unusual may have risen from the ashes of an epic smashup. In the middle of a galaxy shaped like an infinity symbol — thought to be the result of two galaxies colliding — sits a supermassive ...

A new study suggests that some of the Universe’s earliest giant galaxies may have lived dramatic lives. They began as dusty ...

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 ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American Last month when scientists announced new ...

(THE CONVERSATION) Billions of light years away in a remote part of the universe, two neutron stars – the ultradense remnants of dead stars – collided. The catastropic cosmic event sent light and ...

Multi-epoch Hubble Space Telescope imaging, tracked over five to seven years, has produced the first direct measurements of ...
