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

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

AAS journals publish research from around the globe. See where our authors are located. The American Astronomical Society (AAS) is the major organization of professional astronomers in North America.

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 ...

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 ...

Not all brightness variations present in a star’s light curve are due to stellar variability — instrumental systematics and artifacts from the spacecraft’s orbital period can produce periodic ...

The premise is not far-fetched: at the ripe old age of nearly 14 billion years, the Milky Way has likely gulped down neighboring dwarf galaxies and globular clusters multiple times. When a black hole ...

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 ...
