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

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

Now, the team has obtained new photometry from the Gran Telescopio Canarias and the United Kingdom Infra-Red Telescope, plus spectroscopy from the Gran Telescopio Canarias, to get a better sense of ...

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 ...

Need a place to publish works in progress, comments and clarifications, null results, or timely reports of observations in astronomy and astrophysics? RNAAS is open for submissions. The American ...

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 ...

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 ...

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, ...

This is the SPHEREx survey strategy, with a few complications. First, before any filter, SPHEREx splits incoming light into two beams, with short-wave infrared light (SWIR, with 0.75 μm < λ < 2.42 μm) ...

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 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 ...

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 ...
