New type of supernova could destroy planet's atmosphere : should earthlings be afraid of this event

A cosmic explosion could lead to the depletion of the ozone layer and the mass extinction of living creatures on the planet.

A supernova explosion for a planet on which life exists, such as Earth, is a real disaster. As a result of the appearance of a supernova, the planet will be covered with deadly radiation. But a new study has revealed another threat, which is a special type of supernova. During this explosion, the ozone layer, which protects all life from cosmic radiation, may disappear. Should the inhabitants of the Earth worry about these cosmic phenomena, says the publication Space.

Supernovae

When a giant star ends its life path, it turns into a supernova as a result of a series of very powerful explosions. When this happens, supernovae become one of the brightest objects in the universe and their light can be compared with the light of hundreds of billions of stars.

Scientists expect that soon (soon in this case it is several million years) the star Betelgeuse , which is more than 600 light-years away from us, will explode in a supernova. When this happens, the second brightest object after the Sun will appear in the Earth's sky. For example, even at night on Earth, everything will cast shadows for several weeks after the explosion.

Even though a supernova produces a huge amount of visible light that can easily blind a person, more dangerous is the X-ray and gamma radiation that comes out of a supernova.

It is believed that supernova gamma radiation can damage the Earth's atmosphere and especially the ozone layer, which protects all life on the planet . Thus, the strong ultraviolet radiation of the Sun can lead to mass extinction.

But an even greater threat comes later. This applies to cosmic rays that escape from a supernova hundreds and thousands of years after the explosion. They can completely destroy the ozone layer and cover the planet with a lethal dose of radiation. Scientists believe that something similar has already happened in the history of the Earth just a few million years ago. But astronomers believe that the Earth is relatively safe, because there are no supernova candidates nearby that could pose a threat to life on the planet.

A new type of supernovae

An international team of scientists has presented a study in which they point to the existence of a new type of supernovae that further threaten the planets in the galaxy. Especially those that are similar to the Earth and can potentially support life. According to astronomers, these supernovae can release an additional, more distant, form of deadly radiation that poses a serious threat to Earth-like planets.

These supernovae occur when a star that is about to die has a thick disk of ejected matter around it. After the initial explosion of a supernova, a shock wave appears and crashes into this disk. This wave heats the disk to incredibly high temperatures, causing large amounts of X-rays to escape from it.

Such radiation can carry much more energy farther away from the explosion site. According to scientists, such X-ray supernovae could initially destroy up to 50% of the ozone layer of an Earth-like planet, and this is enough for all life to disappear. The worst thing is that such supernovae can inflict several blows with their radiation at the same time.

But in a few tens of months, and possibly decades, cosmic rays will finally destroy the atmosphere and all life on the planet. Fortunately, the Earth remains safe as there is no X-ray supernova candidate nearby, scientists say. The study suggests that the Earth is located in one of the safest areas in our entire galaxy.

Focus already wrote that the Hubble Space Telescope took a picture of a huge supernova remnant that is in the galaxy -satellite of the Milky Way.

As for more “mundane” cosmic phenomena, as Focus already wrote, in the coming days in the night sky it will be possible to observe the most powerful stream of “shooting stars” .
