Editor’s Note: Astrobites is a graduate-student-run organization that digests astrophysical literature for undergraduate ...

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

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

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 ...

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 ...

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 ...

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 ...

This apparent paradox comes from the different nature of cold and warm clouds. Cold clouds are denser and more compact, occupying much smaller physical scales than warm clouds. So to match the length ...
