Gamma-ray bursts (GRBs) are short-lived outbursts of the highest-energy light.
They erupt with a quintillion (a 10 followed by 18 zeros ) times the luminosity of our Sun .
Now thought to announce the births of new black holes, they were discovered by accident.
The closest GRB on record occurred more than 100 million light-years away.
The more GRBs astronomers study, the more likely they'll encounter events that challenge current classifications.
GRB afterglows occur when material in the jets interact with surrounding gas.
They emit radio, infrared, optical, UV, X-ray, as well as gamma-ray light, which provides more data about the original burst.
Afterglows linger for hours to days (or even years ) longer than their initial explosion, creating more opportunities for discovery.
GRBs also connect us to one of the universe’s most sought-after messengers, gravitational waves.
