🪐 In 1997, the BeppoSAX satellite pinpointed the source of a gamma-ray burst—GRB 970228—to a faint galaxy about 8 billion light-years away, confirming that gamma-ray bursts can originate far beyond our own Milky Way. This discovery revealed that these bursts are not just local events but are among the most powerful explosions in the universe, releasing in seconds as much energy as the Sun will emit over its entire lifetime. ✨ #gamma-ray-bursts ⚡#explosions⚡#distant-universe ⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels ​

🪐 The dwarf galaxy GRB Host 080605, located nearly 6.5 billion light-years away, is home to one of the brightest long-duration gamma-ray bursts ever detected. This powerful explosion, which lasted over a minute, released more energy than our Sun will emit in its entire lifetime, making GRB 080605 a textbook example of how collapsing massive stars can light up distant galaxies with blinding bursts of high-energy light. ✨ #gamma-ray-bursts ⚡#distant-galaxies ⚡#cosmic-explosions ⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels ​
