GW150914 is the first ever detection and proof of the existence of gravitational waves! The waveform, detected by both LIGO observatories, Hanford and Livingston, matched the predictions of general relativity […]
On January 4th, 2017, LIGO detected two black holes merging into one. One of the black holes was 32 times the mass of the Sun while the other was 19 […]
GW170104 event with the two black holes follow their course spiraling around each other.
This illustration shows the two black holes of the GW170104 event orbiting around each other and slowly coalescing before finally merging.
Rare Ultra-Long Gamma-Ray Burst with transparent color scheme.
The NASA Swift satellite observed a long-lasting blast of high-energy light, revealing that the gamma-ray burst was a rare and newly recognized class of ultra-long gamma-ray burst emanating from a […]
Previously, the nebula CTA 1 showed an expanding supernova remnant, a jet, and a point source expected to be a pulsar. But no radio pulses were detected. NASA’s Fermi Space […]
