Japanese astronomer Yuji Nakamura discovered the aftermath of a star exploding about 10,000 light-years from Earth, which was previously unseen.

Nakamura observed the starburst on March 18, 2021 using his telescope’s 135mm lens and exposing it for 15 seconds.

The Japan National Astronomical Observatory (NAOJ) reported a flare of 9.6 degrees, which deployed a series of powerful telescopes to make observations that confirmed it was indeed a classic supernova, and they named it V1405 Cas.

The classic supernova is a nuclear explosion on the surface of a white dwarf, which is part of a binary system of aging and dying stars. Usually these eruptions last about 12 hours.

As the two stars engage in their shared death spiral, the smaller and denser white dwarf is pushing material, such as hydrogen gas, away from its larger partner.

Then the hydrogen in the white dwarf’s atmosphere is heated up until the time when nuclear fusion is born, releasing an enormous amount of energy while ejecting the remaining unburned hydrogen into space.

The glow of the supernova is expected to persist for days, if not months, and is still visible in the northern hemisphere’s night sky.

And if you live in the Northern Hemisphere and have a telescope, you might want to take a first-hand look at this exciting event, and telescopes can be directed at the right ascending coordinates 23 24 47.73, declination +61 11 14.8, near the star Caph in the constellation of Cassiopeia.
