The newly-developed map of the local Universe is based on the motions of 56,000 galaxies, according to a team of astrophysicists from the Leibniz Institute...
Primordial black holes are one of the strongest candidates for the Universe’s dark matter. In this scenario, their abundance would be large enough for...
It’s 7 billion years ago, and the Universe’s heyday of star formation is beginning to slow. What might our Milky Way Galaxy have looked like at that...
Using the Atacama Large Millimeter/submillimeter Array (ALMA) and the Subaru Telescope, astronomers have discovered a pair of merging gas-rich galaxies...
In a paper published today in the Astronomical Journal, astronomers analyzed the evolution of massive galaxies at redshifts of 4-8 selected from the JWST...
To celebrate the 25th anniversary of NASA’s Chandra X-ray Observatory, the Chandra team has released a set of 25 new images of cosmic objects and phenomena.

Astronomers using the NASA/ESA/CSA James Webb Space Telescope have spotted at least five young globular clusters within SPT 0615-JD1 (also known as the...
Astronomers have discovered a pair of merging quasars seen only 900 million years after the Big Bang. Not only is this the most distant pair of merging...
Astronomers using the NIRSpec (Near-Infrared Spectrograph) instrument onboard the NASA/ESA/CSA James Webb Space Telescope have obtained the spectrum of...
ESA’s Euclid mission has released five new images that showcase the telescope’s ability to explore two large-scale cosmic mysteries: dark matter and...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have found evidence for an ongoing merger of two galaxies and their central black holes —...
