Giant array of low-cost telescopes could speed hunt for radio bursts, massive black holes

When the immense Arecibo radio telescope in Puerto Rico collapsed in 2020, it left gaping holes in astronomy. Now, a team from the California Institute of Technology (Caltech) hopes to address some of the gaps with a very different instrument: a tightly packed array of relatively inexpensive radio dishes that…

Brightest gamma-ray burst ever reveals new mysteries of cosmic explosions Black Hole

Brightest gamma-ray burst ever reveals new mysteries of cosmic explosions

In 2022 on October 8, an intense pulse of gamma-ray radiation swept through our solar system. The source, dubbed GRB 221009A for its discovery date, turned out to be the brightest gamma-ray burst (GRB) ever recorded. GRB 221009A lasted over 300 seconds. According to astronomers, such “long-duration” GRBs are the…

Brightest gamma-ray burst ever observed reveals new mysteries of cosmic explosions

On October 9, 2022, an intense pulse of gamma-ray radiation swept through our solar system, overwhelming gamma-ray detectors on numerous orbiting satellites, and sending astronomers on a chase to study the event using the most powerful telescopes in the world. The new source, dubbed GRB 221009A for its discovery date,…
