An international team of astronomers reports the detection of a peculiar merger of two similar ring galaxies that morphologically resemble an owl's face. The discovery of this galaxy merger ...

As they slowly lose energy, the dwarf galaxies merge into the larger galaxy." That problem, identified by earlier studies, has been amplified by the new study.

Deep in the constellation Canes Venatici, also called the Hunting Dogs, lies the dwarf galaxy NGC 4449. It's part of the M94 galaxy group, near a group of galaxies to which our Milky Way belongs.

Galaxy merger Arp-Madore 417-391 is on display in this new image captured by the Hubble Space Telescope's Advanced Camera for Surveys (ACS). The merger is about 670 million light-years away from ...

Unexpected large-scale clustering of isolated, diffuse and blue dwarf galaxies, comparable to that seen for massive galaxy groups, challenges current models of cosmology and galaxy evolution.

Two bright star-forming regions light up the spiral’s edges, one mirroring Ambartsumian’s Knot, the other possibly a ...
