About 12 billion years ago, a dwarf galaxy known as LKH collided with a young Milky Way and merged with it. This artist’s concept portrays that collision. NASA’s Hubble Space Telescope uncovered definitive evidence of this collision by studying globular star clusters. Illustration: NASA, ESA, Joseph Olmsted (STScI) Our home galaxy, the Milky Way, grew

A new study using data from NASA’s Hubble Space Telescope finds that star formation in the nearby Andromeda galaxy has seen a 500-million-year decline, with an even steeper decline over the past 40 million years. Andromeda, a spiral galaxy comparable in size to our Milky Way, is close enough to be seen with the naked

The subject of this NASA/ESA Hubble Space Telescope image is a spiral galaxy battling titanic forces appearing on galactic scales in space. This is NGC 4654, an intermediate spiral galaxy in the constellation Virgo (the Maiden). It is classified as “intermediate” because its overall shape falls between spiral galaxies that have a bar in their

NASA Hubble Discovers First of Star Cluster’s Missing Black Holes – NASA Science 0

The enormous globular star cluster Omega Centauri has baffled astronomers for decades. It should be full of black holes left by exploding stars, but the evidence for them is scarce. Now, astronomers using archival data from NASA’s Hubble Space Telescope and supporting observations from NASA’s James Webb Space Telescope have finally located their first stellar-mass
