In Photos: Hubble Captures Echoes Of Violent Supernova ‘Fireworks’ That Lit-Up Night Sky In The Third Century - Forbes

[+] exploded long ago in the Small Magellanic Cloud, a satellite galaxy of our Milky Way located roughly 200 000 light-years away.

The Hubble Space Telescope has captured light from a supernova blast—an exploding star—that would have been seen from Earth 1,700 years ago.

It’s now visible to the Hubble Space telescope as a delicate greenish-blue shell—a supernova remnant (SNR)—in a nearby galaxy to the Milky Way called the Small Magellanic Cloud (SMC).

“A prior study compared images taken years apart with two different cameras on Hubble, the Wide Field Planetary Camera 2 and the Advanced Camera for Surveys (ACS),” said Danny Milisavljevic of Purdue University in West Lafayette, Indiana, one of the leaders of the research team whose paper was presented yesterday at the 237th meeting of the American Astronomical Society.

“It’s a testament to the longevity of Hubble that we could do such a clean comparison of images taken 10 years apart.”.

The Small Magellanic Cloud is a satellite galaxy of our Milky Way.
