register Astronomy scientists In the United States, faster Explosion of a star Nova was ever seen.
They watched a white dwarf star “steal” gas from a nearby red giant and triggered an explosion bright enough that it might be seen from Earth with binoculars.
there was an explosion nova Named V1674 Hercules, 100 light-years away, it is three times faster than any previous explosion.
The material was launched into space at millions of miles per hour – which was visible from Earth for just over 24 hours before fading out.
“It was as if someone was turning on a searchlight and turning it off,” said lead author Professor Sumner Starfield, from Arizona State University.
“It was regarding a day away, and the previous fastest nova was the one we studied back in 1991, the V838 Herculis, which went down in regarding two or three days,” Professor Starfield stated.
“Nova events at this level of speed are rare, making this nova a valuable subject of study. Its speed wasn’t the only unusual feature – light and energy also send out impulses like the sound of a bell.”
Experts from Arizona State University hope their observation will help answer larger questions regarding the chemistry of our solar system, the death of stars and the evolution of the universe.
The bright nova usually fades in two weeks or more, but V1674 Hercules ended in a day.
And his speed wasn’t the only unusual feature – light and energy also sent out impulses like the reverberating sound of a bell. And every 501 seconds, there is an oscillation that can be detected in the visible and X-ray light waves. And there’s still a year left – and it’s set to last much longer.
“The weirdest thing is that this oscillation was seen before the explosion,” said Mark Wagner, chief science officer at the Big-Eyed Telescope Observatory at Mount Graham in southern Arizona. “But it was also evident when the nova was 10 degrees brighter. It drives this periodicity that you might see above the bright band of the system.”
The American team also noticed strange winds while observing the material emitted from the nova, which they believe may be dependent on the locations of the white dwarf and its companion star.
It is believed that regarding 30 to 60 novas occur each year in the Milky Way. The white dwarf collects and alters matter, then spoils the surrounding space with new matter when it goes supernova. It is an important part of the cycle of matter in space as the material ejected by novas will eventually form new star systems.
Events like these helped shape our solar system as well, ensuring that Earth isn’t just a block of carbon.
