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

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

Luckily, one transit astronomer’s trash data can be a pulsation timer’s treasure. For some A-type stars called δ Scuti stars, ...

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.

The authors find that the mass of the galaxy is 0.21 x 10 12 solar masses, the circular velocity of the galaxy at the maximum radius they look at (21.1 kpc) is 206 km/s, and the virial radius is 1.28 ...

This study highlights the need for careful consideration of selection effects and uncertainties, even with advanced and deep instruments like JWST. Obtaining measurements for low-mass black holes is ...

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 ...

Figure 2: Convective power vs. radius in the 12 supernova simulations (with non-rotating progenitor stars) analyzed by the authors. The color gradient represents the time since the infalling outer ...

There’s plenty of evidence pointing to magnetars as the source of FRBs, from polarization measurements that suggest FRB sources are strongly magnetized, to localizations of several FRBs to ...

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 ...
