"SPT2349-56 is a system so extraordinary that we may have caught one of the most massive clusters under formation at a very ...

Because the density of galaxies is high within clusters, galaxy collisions occur. One such collision can be seen in the lower right of the image of the Virgo cluster below. Galaxies at the center ...

Comprised of over 2,000 galaxies, the Virgo cluster is located about 54 million light-years away. Astronomers made these composite images from the advanced camera's full field-of-view observations.

Meanwhile, Chris Mihos, professor and chair of astronomy, has concluded from telescopic observations that in the nearby (cosmically speaking) Virgo Cluster of galaxies, 20 to 30 percent of the stars ...

The Hubble Space Telescope captured an image of a star and a spiral galaxy, both in the constellation Virgo. But the photo is an optical illusion.
