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
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
You’ve got to move fast on #BlackFriday2018 when there are limited quantities
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
Massive Triple Star System Creates this Bizarre Swirling Pinwheel of Dust. And it Could be the Site of a Gamma Ray Burst
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.
The study which describes the team’s findings was recently published in the scientific journal Nature. The team was led by Joseph R. Callingham, a postdoctoral fellow from the Netherlands Institute for Radio Astronomy (ASTRON), and included members from the Sydney Institute for Astronomy (SIfA), the Royal Observatory Edinburgh, the University of Sheffield and the University of New South Wales.

‘God of chaos’: Milky Way star on the brink of massive gamma-ray supernova explosion
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.
What do sand, glass ⌛ and this technicolor remnant of a supernova 💥 have in common?
They all contain silica, a mineral that’s widespread on Earth and in space.
Using NASA’s Spitzer Space Telescope, researchers found that the material is produced by the massive explosions of stars. Details: https://go.nasa.gov/2r6Zq7P
