X-ray absorption observations toward a black hole transient reveal the interstellar dust grain composition along the line of sight: a silicate magnesium-rich amorphous pyroxene and metallic iron.

JWST has detected more than a dozen new candidate H II regions, despite extensive radio surveys of the region, and these observations suggest that infrared photons can escape even dense, dusty gas.

A curious gamma-ray burst with ambiguous properties may have been caused by a giant flare from a magnetar, but this would make the event three orders of magnitude more energetic than others of its class.

No bursty radio emission characteristic of star–planet interaction was detected from a sample of five M dwarfs with close-in terrestrial planets, but researchers were able to place limits on the magnetic fields of the planets.
