the little one The dim, red dot in the center of the newly released image of a distant galaxy indicates the galaxy underwent one of the most powerful explosions since the Big Bang. Astronomer Brendan O’Connor and his colleagues recently discovered this as-yet-unnamed galaxy 9 billion light-years away in data from the Gemini North Telescope in Hawai’i, and they say it is the source of a brilliant, bright beam of gamma radiation. brief dazzling NASA. Swift Observatory in late 2015. Imagine an explosion releasing as much energy as our Sun would in 10 billion years – compressed into an explosion in less than two seconds. Astronomers call this almost unimaginable catastrophe a short gamma-ray burst, and the universe hasn’t seen a brighter or more powerful explosion since the Big Bang. What could cause such an event? The answer appears to involve two colliding neutron stars. Binary star systems are not very rare in the universe; one of our closest neighbors, Alpha Centauri, is actually

Just a week after its first images were shown to the world, the James Webb Space Telescope may have discovered a galaxy that existed 13.5 billion years ago, a scientist analyzing the data said Wednesday. Known as GLASS-z13, this galaxy dates back to 300 million years after the Big Bang, about 100 million years earlier than anything previously identified, Rohan Naidu of the Harvard Center for Astrophysics told AFP. “We are potentially seeing the light of the most distant star that anyone has ever seen,” he said. The further away the object is from us, the longer it will take for its light to reach us, and so gazing back into the distant universe is looking into the deep past. JWST has the potential to break records, discovering galaxies that existed when the universe was only 300 million years old! Light from GLASS-z13 took 13.4 billion years to reach us, but the distance between us is now 33 billion light years due to the expansion of the universe! pic.twitter.com/5AcOBwHuO1 — Dr. Ja
