The European Southern Observatory (ESO) has released a gorgeous new image taken by ESO’s Very Large Telescope (VLT) of a giant elliptical galaxy called...
Many thousands of compact and massive star clusters have formed at an approximately steady rate over the past one billion years around NGC 1275, the central...
NASA has released a breathtaking image snapped by the NASA/ESA Hubble Space Telescope of the Arp-Madore 2026-424 system.
This Hubble image captures two...
Using data from NASA’s Chandra X-ray Observatory, astronomers have created detailed maps of Abell 1758, a collision between two pairs of galaxy clusters,...
Are we alone in the Universe? It comes down to whether intelligence is a probable outcome of natural selection, or an improbable fluke. By definition,...
In a new paper published this month in the journal Physical Review D, a duo of theoretical physicists from Case Western Reserve University, the University...
Astronomers using the Atacama Large Millimeter Array (ALMA) have discovered faint traces of a huge dust-obscured star-forming galaxy never seen before,...
Super spirals are the most massive star-forming disk galaxies in the Universe. They are much larger, brighter, and more massive than our own Milky Way...
Astronomers have used a huge group of galaxies called the Phoenix cluster as a cosmic magnifying glass to detect X-ray emission from a very distant dwarf...
Supermassive black hole-driven outflows in dwarf galaxies have a significant impact on the evolution of these galaxies by suppressing star formation, according...
Our Milky Way Galaxy is orbited by more than 50 companion galaxies. According to new research led by University of California, Riverside astronomers, several...
Using data gathered by the NASA/ESA Hubble Space Telescope, astronomers have calculated the mass inflow and outflow rates of cool ionized gas around our...
In a paper published in the journal Physical Review Letters, an international team of physicists proposes a new strategy for searching for hypothetical...
The NASA/ESA Hubble Space Telescope has produced a beautiful image of the spiral galaxy NGC 3717.
This Hubble image shows the edge-on spiral galaxy NGC...
An analysis of data from the Pan-Andromeda Archaeological Survey (PAndAS) has uncovered two major episodes of accretion, probably separated by billions...
Using the Subaru, Keck, and Gemini telescopes, astronomers have discovered a young cluster of galaxies in the early Universe. Named z66OD, the protocluster...
Using data from several space- and ground-based telescopes, astronomers have discovered a system of three supermassive black holes within SDSS J084905.51+111447.2,...
Using data collected by the NASA/ESA Hubble Space Telescope, astronomers have created the deepest ever catalog of variable sources (variable stars in our...
A new visualization created by a team of astrophysicists at NASA’s Goddard Space Flight Center illustrates how black hole’s gravity distorts our view,...
High-speed particle jets from gamma-ray bursts may exceed the speed of light in surrounding gas clouds, but do so without violating Einstein’s theory...
