Supergiant star explosion seen live by astronomers for first time
Scientists have watched live as a red supergiant star came to its dramatic end for the first ever time.
The research marks a major moment for our understanding of the death throes of stars – those moments before they detonate in spectacular, violent eruptions.
It also suggests that our understanding of what happens before red supergiants explode is wrong. Previously, they looked as if they were relatively calm before bursting into their dramatic death – but in the latest observations, scientists saw bright radiation coming from the star that seemed to indicate something more significant was happening inside.
“This is a breakthrough in our understanding of what massive stars do moments before they die,” said Wynn Jacobson-Galán, the study’s lead author.
“Direct detection of pre-supernova activity in a red supergiant star has never been observed before in an ordinary type II supernova. For the first time, we watched a red supergiant star explode.”
The research, ‘Final Moments. I. Precursor Emission, Envelope Inflation, and Enhanced Mass Loss Preceding the Luminous Type II Supernova 2020tlf’, is published today in the Astrophysical Journal.
Researchers first spotted the doomed star in summer 2020, when vast amounts of light were spotted coming out of it by the University of Hawaii Institute for Astronomy Pan-STARRS on HaleakalÄ. They were then able to watch it – with that telescope and the nearby WM Keck Observatory on Maunakea – in the days that followed, until it exploded in a bright supernova a few months later.
“It’s like watching a ticking time bomb,” said Raffaella Margutti, an adjunct associate professor at CIERA and the paper’s senior author. “We’ve never confirmed such violent activity in a dying red supergiant star where we see it produce such a luminous emission, then collapse and combust, until now.”
Astronomers now hope they can use the research to look through the universe for more stars that are throwing out that luminous, ominous radiation and see whether it signals the imminent death of that star.
“I am most excited by all of the new ‘unknowns’ that have been unlocked by this discovery,” said Jacobson-Galán.
“Detecting more events like SN 2020tlf will dramatically impact how we define the final months of stellar evolution, uniting observers and theorists in the quest to solve the mystery on how massive stars spend the final moments of their lives.”

Hi PSI Readers,
“Scientists have watched live as a red supergiant star came to its dramatic end for the first ever time.”
Maybe not if you read the previous PSI article.

CAUGHT FOR THE FIRST TIME: THE EARLY FLASH OF AN EXPLODING STAR
March 22, 2016
I point this out to a PSI Reader to ask where else can you so conveniently find these two articles about a similar astronomical events. For I find, in this previous article the additional information: “”All heavy elements in the universe come from supernova explosions. For example, all the silver, nickel, and copper in the earth and even in our bodies came from the explosive death throes of stars,” said Steve Howell, project scientist for NASA’s Kepler and K2 missions at NASA’s Ames Research Center in California’s Silicon Valley. “Life exists because of supernovae.” “ “. I can accept this possibility of ‘IN THE BEGINNING’ before the earth was formed. For it seems far simpler than ONE BIG BANG!!! Of course this solid and gaseous debris must recombine to form our solar system So it seems to be a continuing saga. However, I ask: Why couldn’t the SUPERNOVAE have been formed during the same period of time as our solar system was formed??? Questions like this are interesting to ponder. But I urge a reader to also read the first page of ‘The Holy Bible’.
Have a good day, Jerry

“In the beginning, the Earth was without form, and void.” refers to lack of valid contract and thereby “persons” in particular. “Persons” referring to corporations, the dead strawman, the legal fiction. The 1611 King James Bible states in numerous places:
King James Version 1611
As taken ad verbatim from For God is no respecter of persons.
Deuteronomy 16:19 Thou shalt not wrest judgment; thou shalt not respect persons, neither take a gift: for a gift doth blind the eyes of the wise, and pervert the words of the righteous.
Deuteronomy 1:17 Ye shall not respect persons in judgment; but ye shall hear the small as well as the great; ye shall not be afraid of the face of man; for the judgment is God’s: and the cause that is too hard for you, bring it unto me, and I will hear it.
Deuteronomy 10:17 For the LORD your God is God of gods, and Lord of lords, a great God, a mighty, and a terrible, which regardeth not persons, nor taketh reward:
2 Chron. 19:7 Wherefore now let the fear of the LORD be upon you; take heed and do it: for there is no iniquity with the LORD our God, nor respect of persons, nor taking of gifts.
Job. 13:7 Will ye speak wickedly for God? and talk deceitfully for him? 13:8 Will ye accept his person? will ye contend for God? 13:9 Is it good that he should search you out? or as one man mocketh another, do ye so mock him? 13:10 He will surely reprove you, if ye do secretly accept persons.
Proverbs 24:21 My son, fear thou the LORD and the king: and meddle not with them that are given to change: 24:22 For their calamity shall rise suddenly; and who knoweth the ruin of them both? 24:23 These things also belong to the wise. It is not good to have respect of persons in judgment. 28:21 To have respect of persons is not good: for a piece of bread that man will transgress.
Lamentations 4:16 The anger of the LORD hath divided them; he will no more regard them: they respected not the persons of the priests, they favoured not the elders.
Acts 10:34 Then Peter opened his mouth, and said, Of a truth I perceive that God is no respecter of persons: 10:35 But in every nation he that feareth him, and worketh righteousness, is accepted with him.
Romans 2:11 For there is no respect of persons with God.
Ephesians 6:9 And, ye masters, do the same things unto them, forbearing threatening: knowing that your Master also is in heaven; neither is there respect of persons with him.
Colossians 3:25 But he that doeth wrong shall receive for the wrong which he hath done: and there is no respect of persons.
James 2:8 If ye fulfil the royal law according to the scripture, Thou shalt love thy neighbour as thyself, ye do well: 2:9 But if ye have respect to persons, ye commit sin, and are convinced of the law as transgressors. 2:10 For whosoever shall keep the whole law, and yet offend in one point, he is guilty of all.
1 Peter 1:17 And if ye call on the Father, who without respect of persons judgeth according to every man’s work, pass the time of your sojourning here in fear: 1:18 Forasmuch as ye know that ye were not redeemed with corruptible things, as silver and gold, from your vain conversation received by tradition from your fathers; 1:19 But with the precious blood of Christ, as of a lamb without blemish and without spot: 1:20 Who verily was foreordained before the foundation of the world, but was manifest in these last times for you, 1:21 Who by him do believe in God, that raised him up from the dead, and gave him glory; that your faith and hope might be in God.

Rightfull judgement, or karma, as dealt by God, respects nobody, as is demanded by the laws of balance.
