A stunningly concentrated and hefty galaxy cluster, from a time in the universe's history when such massive structures aren't expected to have fully formed yet, is challenging cosmic evolution theories. Across a series of ...
This NASA Hubble Space Telescope image features a galaxy cluster called CL0016+1609, or MACS J0018.5+1626, that is very bright at X-ray wavelengths and is one of the most extensively studied clusters at X-ray and radio wavelengths. ...
Astronomers have revealed new details about how young stars shape their galactic surroundings in a new study. Researchers analyzed about 18,000 star-forming regions in nearby spiral galaxies using data from powerful instruments ...
NASA's "rapid-response" space telescope is slowly falling out of orbit, but a daring mission this summer could allow the Neil Gehrels Swift Observatory to continue scanning the sky for many more years to come. In the first ...
Researchers using two of humanity's most powerful observatories—NASA's James Webb and Hubble Space Telescopes—have definitively shown that Terzan 5 is not a globular star cluster, as it was once classified, offering new insight ...
A Yale-led team of astronomers has found a third galaxy devoid of dark matter—located alongside the other two in a formation that has never been seen before. Astronomers have followed a faint, cosmic trail of gas to a third ...
An international team of astronomers led by Camille Poitras, a Ph.D. student in the Faculty of Science and Engineering at Laval University, has produced the most detailed X-ray view ever obtained of the jet launched by the ...
In the early universe, the first galaxies began to take shape roughly a million years after the Big Bang. Within these young systems, stars formed from vast reservoirs of cold gas, gradually building the structures we see ...
Between the mid-1970s and early 1980s, two physicists, Michael Hart and Frank Tipler, published a controversial series of papers arguing that extraterrestrial intelligence didn't exist. As they argued, the likelihood that ...
This March 20, 2026, image of Messier 64, or the Black Eye Galaxy, is a composite view from NASA's Hubble Space Telescope and James Webb Space Telescope. It shows Messier 64 captured at near- and mid-infrared wavelengths ...
