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

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 ...

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 ...

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 recent years, very massive but dead galaxies were found unexpectedly early in the universe. Now there might be an explanation for this.

Astronomers have discovered a "galaxy-killing wind" that may explain why there are far more massive "dead" galaxies than ...

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 ...

For the first time, astronomers have been able to combine the deepest optical images of the universe, obtained by the Hubble Space Telescope, with equally sharp images in the near-infrared part of the ...

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 ...

For more than a decade, the collision between the Milky Way and Andromeda galaxies has been treated as a settled fact of ...
