The warm, Saturn-size planet TOI-199 b is the first of its class for which we have precise mass and radius measurements, thanks to the Antarctica Search for Transiting ExoPlanets.

The length-based classification scheme of gamma-ray bursts came under strain when a long (i.e., collapsar-based) gamma-ray burst was found to accompany colliding neutron stars.

The complex rotation of the first interstellar object discovered traversing our solar system continues to inspire research; this work investigates the impact of outgassing from the object’s sub-stellar point.

The longest long-duration gamma-ray bursts may be a good place to look for gas rich in r-process elements: elements that are made in hot, dense environments by the rapid capture of neutrons.

A highly confident detection of polarized X-rays from an accreting, weakly magnetized neutron star has allowed researchers to assess the source’s accretion and X-ray emission mechanisms.

In the search for extraterrestrial intelligence, researchers are interested in Barnard’s star, the second-closest star system to Earth, and have predicted what a signal originating from the system might be like.
