Astronomers have managed to detect very long wavelength radio emission from a well-studied, repeating fast radio burst, called FRB 20180916B. What's more, the longer wavelengths arrive 3 days after the shorter wavelength counterpart of the signal! Why?
Read MoreFRB 121102 is one of the few known repeating fast radio bursts, and astronomers are trying to use this new period of activity to understand it better. Some predict the current active phase should end sometime between August 31 and September 9. Will it?
Read MoreSpace-based observatories detected a violent explosion in a galaxy billions of light-years away. It became the brightest source of high-energy cosmic gamma rays seen so far. Specialized Earth-based telescopes detected it via faster-than-light particles cascading through Earth's atmosphere.
