Using data from several space- and ground-based telescopes, NASA astronomers have captured a stunning new image of the Andromeda galaxy, which is the closest...
It is commonly believed that our own Milky Way Galaxy is on a collision course with the neighboring Andromeda galaxy. As a result of their merger, predicted...
Astronomers using the NASA/ESA Hubble Space Telescope have taken a detailed image of a spectacular central part of the Triangulum Galaxy.

The NASA/ESA Hubble Space Telescope has captured this spectacular image of the Pegasus dwarf spheroidal galaxy, a satellite of the Andromeda galaxy.
The...
The Andromeda galaxy (Messier 31), which is located 2.5 million light-years away, is the Milky Way’s nearest large galactic neighbor. By measuring the...
Astronomers from the University of California, Santa Cruz and elsewhere have discovered 208 new RR Lyrae variable stars in the halo of our Milky Way Galaxy;...
Astronomers have discovered a new ultra-faint dwarf galaxy in the constellation of Pegasus and characterized it using deep imaging with the Gemini Multi-Object...
Astronomers have analyzed archival images from NSF’s Zwicky Transient Facility (ZTF), which provides an ideal setup to study the effects of low-Earth-orbit...
The Andromeda galaxy is a barred spiral galaxy 2.5 million light-years from Earth. Otherwise known as Messier 31, it hosts a double nucleus, which is well-explained...
Using the Sardinia Radio Telescope, a 64-m fully steerable radio telescope near San Basilio, Sardinia, Italy, an international team of astronomers has...
Astronomers using the High-Resolution Echelle Spectrometer (HIRES) on the Keck I telescope at W. M. Keck Observatory and the Canada-France-Hawaii Telescope...
Astronomers using the NASA/ESA Hubble Space Telescope have found that a halo of diffuse plasma around the Andromeda galaxy, which is located 2.5 million...
An analysis of data from the Pan-Andromeda Archaeological Survey (PAndAS) has uncovered two major episodes of accretion, probably separated by billions...
The Andromeda galaxy, also known as Messier 31, collided and merged with a large galaxy approximately 2 billion years ago, according to new research. Even...
Astronomers have long thought that the Andromeda Galaxy was 2-3 times the mass and size of the Milky Way, and that our own Galaxy would ultimately be engulfed...
Several dwarf galaxies orbiting around a nearby elliptical galaxy called Centaurus A are rotating in synchrony around their host, to astronomers’ surprise....
A team of astronomers led by University of Colorado Boulder scientists has discovered a mechanism that explains the persistence of asymmetrical star clusters...
Using X-ray data from NASA’s Chandra X-ray Observatory and optical data from ground-based telescopes, astronomers have spotted what could be the most...
