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

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 ...

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 ...

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 ...
