About 170 million years later, the light emanating from the explosion was received by an arsenal of high-powered telescopes here at Earth. While the telescopes observed, a few of those stars ended their long lives in dramatic explosions. See what we learned: https://go.nasa.gov/2rcIaOr&h=AT2ywbQrtay_XNW6uqmtoFtsirkvbj…cfHXkJ10lQ
This dark, tangled web spotted by NASA’s Hubble Space Telescope is a supernova remnant, created after a massive star ended its life in an explosion and threw its constituent material out into surrounding space. Discover more: https://go.nasa.gov/2G0nVgS&h=AT0m92-1V7h2Z6pdebGy-JSLFW…CsgI5QIBpg
Here’s a look at fast-moving jet material from the powerful gravity of a supermassive black hole when a star wandered just a little too close: https://go.nasa.gov/2FAO1XB #BlackHoleFriday
When stars reach the end of their lifespan, many undergo gravitational collapse and explode into a supernova, In some cases, they collapse to become black holes and release a tremendous amount of energy in a short amount of time. These are what is known as gamma-ray bursts (GRBs), and they are one of the most powerful events in the known Universe.
Recently, an international team of astronomers was able to capture an image of a newly-discovered triple star system surrounded by a “pinwheel” of dust. This system, nicknamed “Apep”, is located roughly 8,000 light years from Earth and destined to become a long-duration GRB. In addition, it is the first of its kind to be discovered in our galaxy.
A star 8,000 light years from Earth is on the verge of a huge supernova explosion, which could produce the Milky Way’s first gamma-ray explosion, a dangerous and extremely energetic event.
Australian scientists at the University of Sydney discovered the rare ‘God of chaos’ star, which they say could produce the Milky Way’s first known gamma-ray burst, a lethal combination of dust and gas mixed with wind as fast as 12 million km/ph, which is one of the most extreme energetic events after the Big Bang.
