This James Webb Space Telescope image of Supernova 1987A shows the structures created before and after the explosion. The keyhole was formed from ejected material afterward, while the equatorial ring was made from material ejected thousands of years beforehand: https://bit.ly/482PSxW

Supernova 1987A!

SN 1987A was the closest observed supernova to Earth since the invention of the telescope and has become by far the best studied of all time, with observations of SN 1987A giving astronomers revolutionary insights into the deaths of massive stars.

This image was captured to mark the 30th anniversary of the supernova and check how its remnant is developing.

An article published in the journal "Science" reports new evidence that the supernova SN 1987A generated a pulsar. A team of researchers used observations conducted with the James Webb Space Telescope to detect the effects of high-energy emissions coming from the pulsar or the pulsar wind nebula, a nebula that surrounds it and is powered by the pulsar. These are confirmations of conclusions reached by other teams of researchers in recent years using observations in other electromagnetic bands.

Scientists May Have Just Found The Youngest Neutron Star Ever

“For years, scientists examined this cataclysm’s afterglow, observing the bright, expanding gaseous shells. But inside, embedded within dusty clouds, a remnant core must exist. SN 1987A was a type II supernova: a blue supergiant exploding at its life cycle’s end. These explosions always create either neutron stars or black holes, but none had yet been discovered. Many anticipated a central pulsar’s presence: analogous to the Crab Nebula. But not all neutron stars pulse; some simply emit high-temperature radiation.”

In 1987, the first naked-eye supernova occurred in almost 400 years, as a star in the Large Magellanic Cloud exploded just 168,000 light-years away. In theory, this type of explosion should lead to a neutron star or a black hole, but no evidence for either had ever been found. Despite many searches for a pulsar, no evidence for that behavior had ever turned up.

Well, not all neutron stars pulse, and advances in instruments, particularly with ALMA, have just led to the first detection of evidence for a neutron star! Come see what the fuss is all about.

SN1987A’s shock About 160,000 years ago, one of the galaxies near us, the Large Magellanic Cloud, hosted a stellar explosion. A star reached the end of its life, erupted into a Supernova, and the remnants collapsed inwards to a neutron star. In 1987, light from that supernova reached Earth, creating a show for physicists and astronomers. This Supernova is perhaps the best studied in history as astronomers were able to monitor it during and afterwards with modern telescopes due to its relatively small distance from here.

This set of images was collected by the Blanco 4-meter telescope in Chile. To this day, an expanding shockwave is moving dust out away from the site of the explosion, and light from the supernova is bouncing back and forth off that dust, with some of it eventually reflecting towards Earth and lighting up the dust ring. -JBB Gif credit: The SuperMACHO Team, CTIO, NOAO, NSFhttps://apod.nasa.gov/apod/ap060125.html

SN 1987A & The Honeycomb Nebula

Supernova 1987A by NASA Goddard Space Flight Center Via Flickr: In February 1987, light from an exploding star arrived at Earth after traveling across 160,000 light-years of space. It was the closest supernova humanity had seen in centuries. Thirty-two years later, the light of the supernova itself has faded, but astronomers continue to study its remains for clues about how stars live and die. Scientists will use NASA's James Webb Space Telescope to observe Supernova 1987A (SN 1987A), as it is known, in order to gain new insights into the physics of the explosion and its aftermath. Astronomers combined observations from three different observatories (Atacama Large Millimeter/submillimeter Array, red; Hubble, green; Chandra X-ray Observatory, blue) to produce this colorful, multiwavelength image of the intricate remains of Supernova 1987A.
