Astronomers discover new open cluster with Gaia
Using ESA's Gaia satellite, astronomers have serendipitously discovered a new open cluster in the Milky Way galaxy. The newfound cluster, which received the designation Ash-1, is relatively young and consists of at least ...
Event Horizon Telescope makes highest-resolution black hole detections from Earth
The Event Horizon Telescope (EHT) Collaboration has conducted test observations achieving the highest resolution ever obtained from the surface of the Earth, by detecting light from the centers of distant galaxies at a frequency ...

What makes a supercluster?
By eye, it's impossible to pick out the exact boundaries of the superclusters, which are among the largest structures in the universe. But that's because they are not defined by their edges, but by the common motion of their ...

Hubble captures unique ultraviolet view of a spectacular star cluster
Roughly 210,000 light-years away, the Small Magellanic Cloud (SMC) is one of our Milky Way galaxy's closest neighbors. In fact, this small galaxy is one of the Milky Way's "satellite" galaxies, which orbit our home spiral ...

New hyperluminous quasar discovered
An international team of astronomers reports the discovery of a new hyperluminous quasar. The newfound quasar, which received the designation eFEDSJ0828–0139, has a high star-formation rate and its black hole is accreting ...
Early galaxies not as massive as initially thought, study finds
When astronomers got their first glimpses of galaxies in the early universe from NASA's James Webb Space Telescope, they were expecting to find galactic pipsqueaks, but instead they found what appeared to be a bevy of Olympic ...

Professor proposes how a black hole in orbit around a planet could be a sign of an advanced civilization
In 1971, English mathematical physicist and Nobel-prize winner Roger Penrose proposed how energy could be extracted from a rotating black hole. He argued that this could be done by building a harness around the black hole's ...
