Just 670 years ago, this supernova burst into the night sky

Supernova remnants often conceal the finer details of their origins within clouds of cosmic dust. It’s not easy to tell how long ago a supernova explosion began, but sometimes telescope records can illuminate the past. NASA/CXC/D. Berry; NASA/STSci/Hubble; ESA/M. Kornmesser

Researchers sifting through telescope data recently pinpointed the age of a relatively young remnant located in our neighboring galaxy, the Large Magellanic Cloud.

This week, NASA released a stunning new image of the remnant, called SNR 0519, created using visible light and X-ray data.

Visible light observations from the Hubble Space Telescope and X-ray data from the Chandra X-Ray Observatory were combined to create a breathtaking composite.

Here’s the new image of SNR 0519.

Light from SNR 0519 most likely reached Earth about 670 years ago — give or take seven decades, according to researchers.

They measured how quickly blast materials emanated from the remnant’s center, where the explosion happened centuries ago.

As for what caused the powerful explosion: SNR 0519 burst apart after absorbing matter from a nearby star, or during a powerful collision.

The 670-year estimate is consistent with previous findings — and a further study of Hubble data could help narrow that date down even more in the future.
