Supernova remnants might collapse when they collide with the surrounding interstellar medium, triggering the formation of dense, chemically enriched clouds that could be the site of star formation.

The new measurements represent the highest diffraction-limited angular resolution ever obtained from Earth’s surface and show proof of concept for high-angular-resolution observations of black holes.
A new catalog provides a wealth of data from 140 fast radio bursts, updating or providing for the first time the polarization, raw voltage, and localization information for these bursts.
The discovery of a Milky Way star with iron abundance three orders of magnitude lower than our Sun’s iron abundance may prompt a reevaluation of how metal-poor globular cluster stars can be.
Laboratory experiments provide a way to probe the widely accepted model behind seasonal changes on Mars’s surface, including the formation of “spiders,” “halos,” and “fried eggs.”
The galaxy Corvus A has no known neighbors within 3.3 million light-years and, curiously, exhibits ultraviolet emission indicative of star formation but appears to host no star-forming regions.
