Light from supernova 1987A reached Earth #OTD in 1987. The Hubble space telescope captured this spectacular image for the 30 year anniversary in 2017. 🧪 🔭 ⚛️ Credits: NASA, ESA, R. Kirshner (Harvard-Smithsonian CfA, Gordon and Betty Moore Foundation), M. Mutchler and R. Avila (STScI)

Supernova 1987A is located in the centre of the image amidst a backdrop of red, blue, and orange stars. A bright pink and red ring around the central region of the exploded star is composed of material ejected by the star about 20 000 years before the actual explosion took place. The supernova is surrounded by red and orange gaseous clouds. The color of these clouds represents the glow of hydrogen gas.

What detected the neutrinos from 1987A?

What's amazing is that the actual event occurred 180,000 years ago and that it took that long for the light to reach us and let us know it went BOOM! 😳

This time-lapse of Hubble images taken between 1994 and 2016 shows a ring of ejected material superheat and glow in X-ray as the shockwave from supernova 1987A slams into it. (2/n) Credits: NASA, ESA, R. Kirshner (HSCfA, Gordon and Betty Moore Fnd), P. Challis (HSCfA)
