Scientists have discovered supernova stars that can destroy Earth-like planets with their explosion

Thanks to NASA’s observatory and other telescopes, astronomers have discovered a new threat to Earth-like planets. The reason is called the intense X-ray radiation of stars, which is released after their explosion, according to NASA. According to scientists, the explosion can affect planets at a distance of more than 100 light years. Scientists recorded this phenomenon in a photo using a telescope. “When this impact occurs, it can create a large dose of X-ray radiation that reaches an Earth-like planet. Such an intense impact can trigger extinction on the planet,” the scientists note. Supernova stars. Photo: NASA During the study, NASA observed 31 supernovae. Observations were carried out mainly from several observatories. Scientists have discovered that the planets can be exposed to lethal doses of radiation, which is located at a distance of about 160 light years. At NASA, attention is drawn to the danger of two periods: intense radiation from a supernova during several days after the explosion and when it is minutes and months after it. “If a stream of X-ray radiation sweeps over a nearby planet, the radiation can seriously change the chemical composition of the planet’s atmosphere,” NASA added. Scientists also note that on a planet similar to Earth, this process can destroy a significant part of the ozone, which protects life from the dangerous ultraviolet radiation of a supernova.

According to scientists, there is convincing evidence that supernovae were formed near Earth from about 2 to 8 million years ago. According to researchers, they were at a distance of approximately 65 to 500 light years from Earth. NASA says Earth and the Solar System are now safe from potential supernova explosions, but many other planets in the Milky Way are not. It will be recalled that scientists explained the cause of the bright flash in the Kyiv region on the evening of April 19 and assume that it was caused by a meteorite falling from the Lyrid stream.
