New radio observations provide the best view yet of the WISPIT 2 planetary system, revealing spiral wakes driven by a growing ...

Astrobites reports on the discovery of a new ultra-faint dwarf galaxy in preview data taken before the start of Vera C. Rubin ...

Last year, gravitational wave detectors triggered on what may have been a collision involving a sub-solar-mass neutron star.

A new catalog of giant pulses from the Crab Nebula pulsar reveals a feature predicted to exist but not seen until now.

New simulations suggest the outer solar system could disassemble within about one billion years after the Sun becomes a white dwarf.

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 ...

The 58th meeting of the AAS Division for Planetary Sciences will take place 25–30 October 2026 in Spokane, WA. Register today! The American Astronomical Society (AAS) is the major organization of ...

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 ...

What happens right before a massive star explodes violently in a supernova explosion? A recent study predicts an influx of pre-explosion observations will arise after the Vera C. Rubin Observatory ...

With this new measurement, the disagreement between observations and the predictions of relativity shrinks to just 2.3%. Looking to the future, Ding and collaborators anticipate that high-sensitivity ...

Luckily, one transit astronomer’s trash data can be a pulsation timer’s treasure. For some A-type stars called δ Scuti stars, the pulsation is regular enough to be used like a cosmic clock. Subtle ...

SN 2010jl offers an excellent chance to study the dust-forming potential of core-collapse supernovae. This supernova was unusually luminous because of intense interactions between the expanding ...
