Creation Moment 9/7/2023 -Latest Lessons of Supernova 1987A

Knowest thou the ordinances of heaven? Job 38:33

"The James Webb Space Telescope team released a stunning image of Supernova 1987A, the nearest supernova since Johannes Kepler observed one in 1604. Astronomers have been monitoring the remnant over time to learn about the aftereffects of exploding stars
(supernovas/supernovae).

A new search for supernova remnants in our galaxy is underway. Scientists are with aiming to find hundreds of these star explosion remains scattered across the Milky Way by using radio observations captured with the Very Large Array (VLA) in New Mexico and the MeerKAT array of radio telescopes in South Africa.
He mentions several of the known SNRs, claiming that their ages range from 130 years to 20,000 years. It should be remembered, however, that astronomers re-dated one SNR from 10,000 years down to 2,000 years (2006 Oct 1). 

The huge, distended SNR called the Veil Nebula, which “looks” really old, was also dated down from tens of thousands of years to 5,000 years in 2001.

As you look at the new JWST image of SN 1987A, remember that all of that structure and motion, spreading out nearly two light-years, took place in just a few decades, within the lifetime of everyone 35 years or older.

The shortage of SNRs comes from belief in Deep Time. 
Most of the visible ones are less than the Biblical age of creation. 

Webb Reveals New Structures Within Iconic Supernova (NASA, 31 Aug 2023). The press release labels the parts of the remnant and offers some preliminary physical explanations of what is taking place in the expanding bubble since the star exploded in 1987 (Earth time). There was hope that the JWST would be able to see a predicted neutron star formed after the core of the star collapsed.
Despite the decades of study since the supernova’s initial discovery, there are several mysteries that remain, particularly surrounding the neutron star that should have been formed in the aftermath of the supernova explosion.
Hundreds of supernova remnants remain hidden in our galaxy. These astronomers want to find them (Space.com, 4 Sept 2023). There’s a paucity of supernovas, reports Keith Cooper. About 300 to 400 supernova remnants (SNRs) are known, he says, but according to theory, “Less than half the predicted number of supernova remnants in our galaxy have been found.”
