These May nights provide the skywatcher impressive views of galactic clusters unimpeded by the Milky Way, the chance to study ...

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 ...

Fully grown galaxy clusters, like the Virgo cluster which contains our galaxy and its local group, are large, gravitationally bound structures dominated by mature elliptical galaxies with little ...

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 ...

Japanese astronomers have presented new results of observations that suggest an unidentified X-ray source designated AX J145732−5901 is a cluster of galaxies behind the galactic plane.

By observation of the Centaurus cluster of galaxies, the XRISM team discovered the existence of a fast-moving, high-temperature gas flow in the center of the cluster. Their findings, published by ...

NASA’s image of NGC 628, also known as the Phantom Galaxy, reveals a stunning face-on spiral galaxy with gracefully winding arms, located about 32 million light-years from Earth.
