Blazars are active galaxies that emit narrow jets of ionized matter from their centers, aimed towards Earth. Depending on properties of the electromagnetic radiation emitted by the jets, astronomers divide such objects into ...
Following a successful launch in the early hours of Wednesday morning (12 March 2025) U.K. time, the PUNCH spacecraft are poised to begin their two-year mission to study the sun's outer atmosphere and its transformation into ...

There is a supermassive black hole at the center of nearly every big galaxy—including ours, the Milky Way (it's called Sagittarius A*). Supermassive black holes are the densest objects in the universe, with masses reaching ...
In the past three years, astronomers have discovered a mysterious new type of radio source. We call these long-period transients.
In just over three years since its launch, NASA's James Webb Space Telescope (JWST) has generated significant and unprecedented insights into the far reaches of space, and a new study by a Kansas State University researcher ...
