Explanation: What powers this unusual nebula? CTB-1 is the expanding gas shell that was left when a massive star toward the constellation of Cassiopeia exploded about 10,000 years ago. The star likely detonated when it ran out of elements, near its core, that could create stabilizing pressure with nuclear fusion. The resulting supernova remnant, nicknamed the Medulla Nebula for its brain-like shape, still glows in visible light by the heat generated by its collision with confining interstellar gas. Why the nebula also glows in X-ray light, though, remains a mystery. One hypothesis holds that an energetic pulsar was co-created that powers the nebula with a fast outwardly moving wind. Following this lead, a pulsar has recently been found in radio waves that appears to have been expelled by the supernova explosion at over 1000 kilometers per second. Although the Medulla Nebula appears as large as a full moon, it is so faint that it took 130-hours of exposure with two small telescopes in New Mexico, USA, to create the featured image.

Dog “remains a mystery”.
Here we go again....
Any of our members Here on this great site and have read my post already know I’m going say something about these astronomical findings.
That being said,
Just how the heck do they know that this star exploded 10,000 years ago?
They never mention that.
All I ask is to be truthful and give us the facts and not what you believe happened.
Once you get into the realm of belief you have left the field of science and have entered religion.
We should all call these things into question.
Just give the facts and stop the unproven theories that have destroyed our education system.
