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 ...

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 ...

Now, a team led by Behzad Tahmasebzadeh (University of Michigan; Villanova University) has investigated the possibility that NGC 4486B’s double nucleus and off-center black hole can be traced to the ...

The discovery of the Martian dichotomy — a ~30 km difference in height between the lower, smooth northern hemisphere and higher, heavily cratered southern hemisphere — was an early indication that the ...

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 ...
