Most galaxies are expected to contain at least one massive black hole, but how robust is this prediction? New research uses ...

Get to know your neighbors with a new database of nearby star clusters, stellar associations, and substellar objects.

Globular clusters have far fewer binary stars than the solar neighborhood. New research identifies black hole burning as the ...

Now, the team has obtained new photometry from the Gran Telescopio Canarias and the United Kingdom Infra-Red Telescope, plus spectroscopy from the Gran Telescopio Canarias, to get a better sense of ...

Primordial Planetesimals in Simulated Water-Rich Disks To test if these water-rich dense cores within Pop III supernova remnants could form planetesimals, the building blocks of terrestrial planets, ...

Enormous, cool stars like Betelgeuse can inform studies of stellar evolution, supernovae, gravitational waves, and more! Dr. Emily Levesque reveals what we can learn from red supergiants in her new ...

While it’s common to find millisecond pulsars in binary systems — in fact, many millisecond pulsars are thought to spin up to their incredible speeds via accretion from a stellar companion — it’s rare ...

Redshift distribution: The median redshift for this sample is z = 3.3, which is higher than that of less luminous galaxies, suggesting that brighter submillimeter galaxies are found at higher ...

Join us in Salt Lake City, UT, 10–14 January 2027 for exceptional science at the 249th meeting of the American Astronomical Society. Register today! The American Astronomical Society (AAS) is the ...

For weak magnetic fields, the gamma-ray cascade should have arrived at Earth hours or days after the neutrino was detected in 2023. These gamma rays are potentially detectable as long as the magnetic ...

But why the connection? How can the black hole know about the galaxy size around it, and vice versa? There are a few proposed explanations for the correlation between central-black-hole mass and its ...

But there’s a catch — at the distances involved, distinguishing between one star and many isn’t easy, and Earendel might not actually be just one star. New research uses stellar population modeling to ...
