Frequencies detected by LIGO

The Laser Interferometer Gravitational-Wave Observatory (LIGO) recorded an unknown “burst” of gravitational waves on January 14, 2020. Gravitational waves are “ripples in the fabric of space-time” and are believed to relate to extreme and unusual cosmic events. They have never been detected before.

The event has been dubbed S200114f. The burst originated from the area of Betelgeuse, a red giant star that is the eleventh-brightest star in the night sky. Astronomers have swung their telescopes to this portion of the sky and are listening across different wavelengths for a whisper of what may have occurred.
