Cassiopeia A
JWST Unveils Stunning Ejecta and CO Structures in Cassiopeia A's Young Supernova
Todays' refutation of creationism comes to us from the field of astronomy and in particular the details of what happened and is still happening in the expanding supernova remnant known as Cassiopeia A which has a super-dense body at its centre, probably a neutron star, the collapsed remains of the parent star.
A neutron star is the remains of an old star that was too large to collapse to a white dwarf but not large enough to become a black hole. In a neutron star, the pressure due to gravity is so intense that even atoms compress, and electrons are forced into protons to become neutrons, so the star becomes nothing but neutrons. Due to conservation of angular momentum a neutron star has a rotation rate in seconds or less.
Cassiopeia A (Cas A) was observed in the night sky 350 years ago. It is 11,000 light years away, so the light the explosion generated reached Earth 11,000 years after the explosion, which simple maths tells us happened 1,350 years before creationists think the Universe was created. It was of course an event in that long, 13.8 billion years pre-'Creation' history of the Universe when 99.99999% of its history, and 99.9975% of the history of Earth occurred.
A supernova like Cas A is the birthplace of star dust out of which Earth and everything on it is made. It is the stuff that connects us to the rest of the universe and to which we, or rather the atoms and molecules that we are made of, will return to be recycled into future planets around future suns, when our own sun swallows up the inner planets then goes supernova itself, and flings our atoms out into the cosmos to be recycled as new suns and planetary systems, maybe to be studied by cosmologists on some other planet wondering about that sudden flash of light in the Milky Way, that was the death of our sun.
As I said in
What Makes You So Special? From the Big Bang to You:
Stars died and because they died, you live. You are made by stars out of stardust and in a very real sense; because you are made of the same stuff the Universe is made of and are a part of it, there is something even more wonderful about you. Through you, though not just through you, and maybe not just here on this small planet, the Universe has gained self–awareness and can begin to understand itself.
Through you it can stand on the surface of this beautiful little jewel in the cosmos, can look up in awe at itself and think "Wow!"
