Brief, brilliant flashes from deep space got a leading explanation. In 2020 astronomers linked a fast radio burst to a magnetar in our own galaxy. It tied the cosmic mystery to extreme, magnetized neutron stars.
Millisecond flashes
The signals are fleeting. Bursts release enormous energy in an instant. Their origin puzzled astronomers.
A galactic source
Proximity helped. A burst came from a magnetar in the Milky Way. It was caught in the act.
Magnetar link
The culprit emerged. Highly magnetized neutron stars can produce the flashes. The case strengthened.
Many origins?
Nuance remains. Not all bursts may share one source. Diversity is possible.
Cosmic probes
Utility grew. Bursts map matter between galaxies. Cosmology benefits.
Rapid discovery
Detections surged. New telescopes find bursts routinely. The catalog explodes.
The bottom line
A 2020 detection linked a fast radio burst to a galactic magnetar, tying the mystery to magnetized neutron stars. Not all bursts may share one origin. The flashes now serve as cosmic probes.
