Globular clusters have far fewer binary stars than the solar neighborhood. New research identifies black hole burning as the ...

The jet-like appearance arises when this arrangement is viewed from the side; the team created synthetic images of their simulated spicules that show individual jet-like features. These “jets” have ...

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

S250818k offered a rare opportunity to associate the light from a kilonova with a gravitational wave detection, a feat achieved only once so far, in 2017. The intrigue surrounding S250818k was ...

However, all of these studies modeled solar mass loss as a smooth function, so the dismantling of the solar system was left up to external forcings. In reality, stars on the red giant branch undergo ...

The authors also infer several properties of Aquarius IV, including its centroid coordinates, half-light radius, ellipticity, distance, and absolute magnitude. They find that its radius is larger than ...

The distribution of gas within the disk, traced by emission from carbon monoxide, roughly follows the pattern seen in previous observations of small dust grains: the orbits of WISPIT 2b and 2c are ...

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 ...

Wassenius penned a short account of his observations in Latin for Philosophical Transactions of the Royal Society (the longest-running scientific journal in the world!). His drawings of the event, ...

For a relatively simple concept, the IMF is shaped by incredibly complicated underlying physical mechanisms. Things like turbulence, magnetic fields, and chemical enrichment all play a role in shaping ...
