"Earth-based catastrophes such as large-scale volcanism and global warming can destroy the ozone layer, too, but evidence for those is inconclusive for the time interval in question," lead author Brian Fields, a professor of physics and astronomy at the University of Illinois, Urbana-Champaign, said in a statement. Astronomers were worried last year when a supergiant star visible to the naked eye from Earth started dimming amid concerns it might explode.. The time lapse covers almost a year of observations, the space agency stated. Several additional supernovae within the Milky Way galaxy have been recorded since that time, with SN 1604 being the most recent supernova to be observed in this galaxy.

The wispy orange streaks running across the image are sections of the supernova blast wave. Supernovas, which end the lives of giant stars like Betelgeuse, can hit Earth life with a powerful one-two punch. "This is entirely possible," said study co-author Jesse Miller, another grad student in Fields' lab. ", The researchers suggested a way to test their hypothesis: look for the radioactive isotopes plutonium-244 and samarium-146 in rocks and fossils from the end-Devonian time period. Pain in ears while wearing masks? NASA has shared a marvellous time-lapse video of an exploding star captured by its Hubble Space Telescope.

The supernova is captured by Hubble in exquisite detail within this galaxy in the lower left portion of the frame. Mike Wall is the author of "Out There" (Grand Central Publishing, 2018; illustrated by Karl Tate), a book about the search for alien life. One of the worst extinction events in Earth's history may have been triggered by a supernova, the violent death of a distant star. A supernova can light the sky up for weeks, and the massive transfer of matter and energy leaves behind a very different star. But while Betelgeuse has returned to normal, researchers have found evidence that Earth was blasted by another exploding star 2.5 million … About 75% of all species on Earth died out at the end of the Devonian Period, nearly 360 million years ago. Then, 70 to 75 years after the star’s death, Earth would get hit by the blast of the supernova.

"Instead, we propose that one or more supernova explosions, about 65 light-years away from Earth, could have been responsible for the protracted loss of ozone," Fields said. Since being shared online, the video has gone viral and prompted many reactions from netizens. However, like “intergalactic paparazzi”, the Hubble Space Telescope was able to quickly capture the self-detonation of a star.

This combo can damage Earth's ozone layer for 100,000 years or so, study team members said. supernova contributed to the minor mass extinction at the end of the Pliocene epoch. The mass extinction at the end of the Cretaceous Period 66 million years ago, which famously did in the non-avian dinosaurs, was likely triggered when a comet or asteroid about 6 miles (10 kilometers) wide slammed into Earth. The supernova called SN 2018gv is located around 70 million light-years away from Earth, in the spiral galaxy NGC 2525.

Video: NASA shares timelapse of exploding star 70-million light-years from Earth The NASA telescope first started watching the supernova, named SN 2018gv, in February 2018. But we’ve done well’. These three panels reveal a supernova before, during and after it happened 920 million light-years from Earth(from left to right).

So the end-Devonian extinction may have involved several different dramatic events — perhaps two or more nearby supernova explosions.

"Neither of these isotopes occurs naturally on Earth today, and the only way they can get here is via cosmic explosions," study co-author Zhenghai Liu, an undergraduate student at the University of Illinois, Urbana-Champaign, said in the same statement. The known history of supernova observation goes back to 185 AD, when supernova SN 185 appeared; which is the oldest appearance of a supernova recorded by humankind. ⁣ Click here to join our channel (@indianexpress) and stay updated with the latest headlines.

Fossil evidence suggests that biodiversity decreased substantially for about 300,000 years at the end of the Devonian, which is often called "The Age of Fishes" because of its tremendous fish diversity. "We are citizens of a larger cosmos, and the cosmos intervenes in our lives — often imperceptibly, but sometimes ferociously.". Such a search has not yet happened, study team members said.
