An analysis of synthetic starspot-crossing events suggests that while starspot longitudes are tightly constrained in high signal-to-noise data, other properties are more loosely determined.

Using data from JWST, the Subaru Telescope, and the Atacama Large Millimeter/submillimeter Array, researchers have identified a previously unseen collimated protostellar jet in a Herbig–Haro object.

Researchers have discovered two chemically distinct populations in a sample of 97 metal-poor stars in the Milky Way halo, potentially providing a way to identify accreted halo stars.

Analysis of blue straggler stars in 56 Milky Way globular clusters finds no evidence for a bimodal distribution in color–magnitude space due to differing formation pathways.

By constructing a detailed distance map to the Magellanic Clouds, researchers have revealed substructures within this interacting galaxy pair, including an azimuthal warp in the Large Magellanic Cloud.

Though the asteroid Apophis will not collide with Earth in 2029, there is a slim but present possibility that it will strike an artificial object orbiting Earth, potentially compromising future missions to the asteroid.
