This month, NASA awarded $500,000 to a research team based in part at the University of Kansas to make the most painstaking assessment ever of the potential damage from a near-Earth supernova.

Luckily for Earth, these supernovas are well outside the calculated kill-distance of about 8 parsecs (or around 26 light-years), where such an explosion would be bad news for life.

To study those possible impacts, Brakenridge searched through the planet’s tree ring records for the fingerprints of these distant, cosmic explosions. His findings suggest that relatively close ...

Yet, supernovas can also be destroyers. If one explodes within about 65 light-years of Earth, its radiation could strip away the ozone layer, exposing the planet to harmful ultraviolet rays and ...

For this reason, evidence of a supernova explosion is sometimes detected in minerals on the seafloor . ・150 light years When the distance between the supernova explosion and the Earth approaches ...

Two years ago, Earth was hit by the most energetic neutrino in history. Scientists thought it might be a measurement error, ...

A supernova explosion is a spectacular event. It unleashes vast energy and creates heavy elements essential for life. Scientists are exploring how these cosmic occurrences impacted life on Earth ...

An exploding star hundreds of light-years from Earth may have played a role in the minor mass extinction 2.59 million years ago.

He assembled a list of supernovas that occurred relatively close to Earth over the last 40,000 years. Scientists can study these events by observing the nebulas they left behind.
