Unusual Star Emissions Baffle Astronomers.

Astronomers studying the V1674 Hercules nova, the fastest and most dramatic ever recorded, have discovered strange radio emissions that are very different from the high-temperature emissions normally seen during such events. The emissions may be from interactions among chunks of stellar material ejected during the explosion, which is quite rare for "classical nova" such as V1674 Hercules. The team hopes to understand what's causing the mysterious radio emissions by combining observations from various telescopes.
