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

Red, white and blue stars shine like a fluttering flare on a dark night in this new image from NASA’s Hubble Space Telescope. NASA released this image to celebrate America’s 250th anniversary, as the agency continues America’s legacy of exploration. Located in the outer halo of our Milky Way galaxy, the globular cluster NGC 6426

Like new fireworks launched against a background of dissipating smoke, blue and white stars shine brightly against a crimson background of glowing gas in this image of the LH 95 stellar nursery from NASA’s Hubble Space Telescope. LH 95 is a region of the Large Magellanic Cloud, a dwarf galaxy orbiting the Milky Way. Low-mass
