Scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) observed a record-breaking stellar flare from Proxima Centauri. The study also marks the first time that a powerful stellar flare, other than those from the Sun, has been observed with such complete wavelength coverage.

The Very Large Array can’t image a big section of sky all at once. Instead, it must scan the sky over time. The VLA Sky Survey is using this method to create a map of nearly 80% of the observable sky. Join our host Summer Ash of the National Radio Astronomy Observatory as she talks about how the VLA is taking the time to see the big picture of the radio sky.

The Event Horizon Telescope (EHT) — the worldwide collaboration that produced the first image of a black hole in 2019 — has produced a new image showing details of the magnetic fields in the region closest to the supermassive black hole at the core of the galaxy M87. The new work is providing astronomers with important clues about how powerful jets of material can be produced in that region.
