Galaxies

Astronomers have traced a high-energy neutrino to a distant galaxy powered by intense star formation rather than a supermassive black hole. The finding challenges previous assumptions about the origins of cosmic neutrinos.

The NASA/ESA Hubble Space Telescope has released a new image of Messier 88, a spiral galaxy moving through the Virgo Cluster. The galaxy hosts a supermassive black hole and shows early signs of gas loss due to cluster forces.

Astronomers using NASA's Hubble Space Telescope have identified a faint galaxy called CDG-2, located 300 million light-years away in the Perseus cluster, that consists almost entirely of dark matter. The discovery relied on detecting four globular clusters rather than the galaxy's dim stars. This finding highlights the role of dark matter in low-surface-brightness galaxies.

Astronomers have detected the brightest and most distant maser, a laser-like beam of microwaves, produced by colliding galaxies nearly 8 billion light years away. The discovery was made using the MeerKAT telescope in South Africa. This phenomenon, amplified by gravitational lensing, may represent a new category of extremely powerful masers.
