A Tour of Supernova 1987A
Ғылым және технология
Thirty years ago on February 24, 1987, observers in the southern hemisphere noticed a new object in the Large Magellanic Cloud. Today, we know this object as Supernova 1987A, and it was one of the brightest supernova seen in hundreds of years. Coupled with its relative proximity at about 160,000 light years from Earth, Supernova 1987A became one of the best opportunities ever for astronomers to study the phases before, during, and after the death of a star.
Since its discovery, telescopes around the world and in space have observed Supernova 1987A. This includes NASA’s Chandra X-ray Observatory, which has looked at this object repeatedly during its 17 years of science operations.
From 1999 until 2013, Chandra data showed an expanding ring of X-ray emission that had been steadily getting brighter. This was produced by the blast wave from the original explosion that had been bursting through and heating the ring of gas surrounding the supernova.
In the past few years, there have been striking changes in the Chandra data. This provides evidence that the explosion’s blast wave has moved beyond the ring into a region with less dense gas. This represents the end of an era for SN 1987A. Since astronomers do not know exactly lies beyond the ring, they will be watching carefully what happens next.
Over the next few thousand years, the expanding shell of hot gas will continue to glow in X rays. Eventually after rumbling across several thousand light years, the shell will disperse. By doing this, the supernova spreads the heavy elements created in the star and possibly triggers the formation of new stars from a cold interstellar cloud. Using data from Chandra and other telescopes, astronomers will continue to learn more about the details of this very important process that is responsible for life as we know it.

I saw this as a young child and remember running inside to tell my family. The night was very clear, the supernova was bright and easily seen by the naked eye.
I saw this super nova when I was a teenager having a piiss on my front lawn at about from 1-3 oclock am after we had been having a keg party when I was about 17.. it was in the middle of my vision right in front of me center.. what are the odds of that ! hahaha I just thank god .. who ever would be lucky enough to see a super novas in their life? . Me .. thanks God , thanks the Universe you are my creator . I feel grateful for that .. I will give back to you .. I love you Universe for that . I was born 20.08.1970

Feb 24 is my birthday. I was 11. Nobody told me about it till now. So stars recycle themselves. That blows my mind.
Its interestyng this video
To think all we see are ghosts of stars. This happened so long ago, it's not that anymore
(1987) While old star's in the morning dew Grow out from earth's layered cocoons When words are lost in mouths full of blood That reddest kiss from epsilon Thy will be destined Verily By lights above Its promise of transit A blossoming
We won't be around to see the development. It takes millions of years.

We are lucky to see anything like this in the existence of humanity. We are half a blink to the universe.
me too, we call that the Kachinas. So this SN exploded years ago and we are just now seeing it's light though it happened long ago. Is it visible right now? I may have caught it with a camera.

funny thing is it happened 160000 years ago
When will we see whats left
My question is why was that ring of dense material there in the first place(before the supernovae)?

The star sheds a lot of material for thousands of years while it expands near the end of its life when it has exhausted the hydrogen in its core and begins to fuse helium. The outer layers of the star accumulate around it until the time that the star goes supernova which then sends the shockwaves and additional materials barreling into these earlier layers of the shredded material.

SN 1987A was unique in the sense that it's progenitor was a blue supergiant rather than the generally red supergiant progenitors. Blue supergiant winds are less dense and faster moving compared to the red supergiant winds. Present understanding suggests that the star had undergone oscillations between blue and red supergiant phases. Due to this, the fast moving blue supergiant wind mixed with the denser slow moving red supergiant wind causing these rings even before the explosion happened.
it's alwso called the keyhole nebula
One ring to rule them all...
The core looks like a figure with short hands. I have just seen an image in which it clearly looked like a chicken :D

Just wondering, how did the artist know to make the ring break up and form those bright wispy balls as it disperses outwards? I watched a video from Think Smarter of Destin colliding two smoke rings together, and when the unified rings expanded and reached a breakpoint, they formed multiple balls and/or smaller other rings. I thought that it was interesting that the artist rendition, on a super macro scale, was similar in look as that experiment done on the smaller micro scale. (Comparatively to the larger nature a supernova explosion of course.)

Nah! That's Sauron in space. I guess he is an alien after all. Maybe it is still searching for the ring of power. 😁😁😁
if a cold gas cloud could turned to a new star, where the gravity come from.
Or maybe the supernova is another aspect of God. We all must find a personal relation with him. Maybe this is how quantum physics made it's personal relation and supernova are one of the byproducts

@@goofyskittles it does take the belief to all new heights though I must say. I mean 4d and 6d beings and levels of existence. These things were mentioned briefly in the texts of Isaiah and Enoch when describing their vision of heaven but to see the same descriptions be proclaimed by a culture of belief some 4000 years later that have absolutely no associated ties to christianity makes you wonder if that isn't the key to the real God, not a defining character solid and set in archaic stone but our interpretatio, whatever that may be, of the one behind the defimition
