GRB 221009A was an extraordinarily bright and very energetic gamma-ray burst (GRB) jointly discovered by the Neil Gehrels Swift Observatory and the Fermi Gamma-ray Space Telescope on October 9, 2022. The gamma-ray burst was ten minutes long, [ 1 ] but was detectable for more than ten hours following initial detection.
GRB 090423 was a gamma-ray burst (GRB) detected by the Swift Gamma-Ray Burst Mission on April 23, 2009, at 07:55:19 UTC whose afterglow was detected in the infrared and enabled astronomers to determine that its redshift is z = 8.2, making it one of the most distant objects detected at that time with a spectroscopic redshift (GN-z11, discovered ...
It was first detected on June 14, 2015, located within a faint galaxy in the southern constellation Indus, and was the most luminous supernova-like object ever observed. [4] At its peak, ASASSN-15lh was 570 billion times brighter than the Sun, and 20 times brighter than the combined light emitted by the Milky Way Galaxy . [ 4 ]
The brightest gamma ray burst ever detected recently reached our planet. It’s 70 times longer than any other burst we’ve spotted, and effectively blinded our instruments when it hit.

The brightest quasar in the sky is 3C 273 in the constellation of Virgo. It has an average apparent magnitude of 12.8 (bright enough to be seen through a medium-size amateur telescope), but it has an absolute magnitude of −26.7. [50] From a distance of about 33 light-years, this object would shine in the sky about as brightly as the Sun.
The slow-motion footage in “Every Little Thing” of hummingbirds captured in flight, or beak deep in a flowering bud or hovering at 50 beats per second are awe-nudging. Director Sally Aitken ...
