This cosmic explosion on the southern side of the equator of the sky is the most spectacular celestial object in the universe, it exploded in 1987.
The James Webb Space Telescope (JWST) captured this rough image of SN 1987A, which shows the center, material ejected from the cosmic explosion framing the shape of the keyhole, and just to its left and right are the newly found faint crescents, and around them is a tropical ring containing brilliant problem areas. Beyond this is a diffuse emanation and two faint outer rings.
One more surprising image, provided by the remarkable James Webb Space Telescope (JWST) from deep space, captured the exploded star SN1987A – which had all the hallmarks of being a neckerchief – giving researchers new insights into the patterns and patterns of stellar existence. their demise.
This cosmic explosion in the southern hemisphere is the most spectacular celestial body in the universe, which exploded in 1987.
It was the closest and most spectacular explosion of a star from Earth, which is located 170,000 light years away. This new image allowed researchers to jump deep into the star while it was on its deathbed.
The image shows the progression of glowing rings that address the groups of gas and debris pushed aside by SN1987A in its various stages of death as it was powered and illuminated by the expanding shock waves emitted in the final image of the collapse and ongoing cosmic explosion.
According to the researchers, one of these rings is a pearl necklace that includes material fired about 20,000 years before the last event.
It became conceivable thanks to the James Webb Space Telescope, which until now provided an unmistakable view of the neck and the diffuse splendor surrounding the star.
JWST also made two pearls that were not visible to the Hubble Space Telescope unmistakable.
"We are ready to see new areas of interest emerging outside the ring that has recently been illuminated," Dr Roger Wesson of Cardiff College in the UK told BBC News.
"Similarly, we see an outflow from atomic hydrogen in the ring that was not really expected and something that could have been detected by just JWST with its prevailing awareness and purpose," he added.
New highlights brought to the fore by James Webb are the crescents or curves of emanation within the grandiose jeweled choker, but just outside the thick inner area that appears to be the keyhole.
"We haven't really figured out those bows yet," said lead investigator Dr. Mikako Matsuura and added that "this material could be illuminated by a reverse shock of some kind—a shock returning toward the keyhole."
Despite its power, JWST cannot see the remnants of the dying star, which are covered somewhere in the dense debris field. These remnants should be minimized items composed of neutron particles and estimated to be only two or three several kilometers in diameter.
Ever since the star underwent a cosmic explosion, every giant telescope that can view SN1987A has noticed and focused on its evolution and various peaks.
Tracing the cause, space experts agree that the star was steamy, moderately young, probably 20 to many times as gigantic as our Sun.
Dr Wesson commented: "One of the mysteries of this star is that it exploded when it was a blue giant, when at the time every hypothesis said that only red giant stars could explode. So unraveling this mystery was one of the incredible missions. " ."
"It means that Webb will be operational for significantly longer than originally thought - maybe 20 years - and that will give us an exceptionally incredible asset to continue to follow SN1987A to see how things are developing."
