Betelgeuse going Supernova?....Sharpest ever images of Betelgeuse reveal how explosive red supergiant loses mass

w ww.dailymail.co.uk

Almost 1,000 times larger than our sun, Betelgeuse is the second largest star in the constellation of Orion and one of the biggest stars known to man.
The red supergiant is also one of the most luminous stars, emitting 100,000 times more light than the Sun.

For decades, astronomers have struggled to explain how the mysterious red supergiants expel such vast amounts of material. They can shed the mass of the Sun in just 10,000 years.

Not sure actually where to post this,sorry

please move this if incorrect

hello everyone im no scientist but i saw a program on tv about the sun other stars and the death of stars etc.

and when a star goes nova or supernova,just before that its sheds most of its atmosphere.

not sure if this is it but looks simmiler to me
prob not but if anybody knows a bit more about this leave a comment.

spelling maybe a bit off ...sorry im dutch

No worries with this one, mate. Supernova stars don't pose much of a threat to us, unless it was our star.

I dont know about that, doesnt a star going supernova give off a plasma burst that if it hit earth it would completley wipe out humanity seems a bit of a risk to me

Incorrect.

Some supernovas can give off a gamma ray burst that if aimed right at us could sterilize the planet.

Yep, I saw on History channel on thursday , and some nice space programe, they claimed stars are born all the time, yet all they present is pictures of dying stars?? What is that about ?

Perhaps this was what all the recent crop circles were alluding to?
Not our Sun,but a different one!

lol well now that would suck wouldnt it? and i know this has been posted already but have to put this up it still amazes me comparing our sun that we think is huge is so tiny compared to all the rest



also i have a question for any one interested because i dont remember ummm is it true that the smaller the sun the hotter its mass is?

sorry thats incorrect because in that same program they said a supernova millions of years ago was responsable for a mayor extinction event.

Could you give me a link to the animation you have supplied?
I am finding it very interesting,but i am unable to take in the true scale in such a small window!
Thanx in advance!

Here are some links with good information on this possible Supernova and the consequences we may endure from it:

Might Betelgeuse Go BOOM

Betelgeuse BOOM - Calamitas Apocalyptica

Both Betelgeuse And Antares - Update

There was a super nova in 1054ad which created what we now call the "crab nebula"

The resultant cloud is light years across now!

According to Burnham, the Chinese records were translated by J.J. Duyvendak (1942; also quoted by Mitton): ".. In the 1st year of the period Chih-ho, the 5th moon, the day chi-ch'ou, a guest star appeared approximately several inches south-east of Tien-Kuan [Zeta Tauri]. After more than a year, it gradually became invisible .." It is this date which is July 4, 1054 AD. Burnham speculates that the term "inches" may indicate that the position was taking on a celestial globe or armillary sphere

I wouldnt be to worried about betelgeuse going supernovae its 520 lightyears away which is a bit to far to do us any harm, never the less nice find and very intresting thanks for sharing.

Thank you for that animation - that really puts us in our place doesn't it? We're just some insignificant pimple whose absence wouldn't even be noticed if Betelgeuse decided to sneeze.

WRONG our star doesnt have enough mass to go supernovae it will turn into a white dwarf,

Well there are many types of supernovae, a star as massive Betelgeuse would likely undergo a Core Collapse, and likely eventually end up as a neutron star or black hole.

As far as Betelgeuse affecting us, no it would not endanger us, although we likely would see quite a bright site in the sky for some time after it went supernovae.

EDIT to add: However there is a possibility many, many, many, many, years down the line that if Betelgeuse becomes a neutron star or black hole that it is close enough to Earth that if it releases a GRB it could potentially be deadly to whatever species is on Earth at that time.

lol that would be very true wouldnt it? i think that if there were a catastrophic event that it wouldve happened already. some people choose to overlook the fact that there was a comet that was roughly twice the size of jupitar that came into our system and shouldve destroyed us if it wernt for our sun....ill have to find the link to the actual footage of this because ive seen it.

if/when Betelgeuse goes Supernova in our lifetime it would be adviseable not to look at it through direct vision. The fact the star would be hundreds of times brighter in manitude than our sun, but only a pin-prick of light means that any direct vision would cause permanent eye damage to the retina. It would be adviseable NOT to even look at it through Solar filters as the discussion is that even these wont provide enough adequate protection.

upergiant star Betelgeuse, reveals an enormous plume of gas almost as big as our own Solar System blasting outwards.

Impressive.

Just to point out that if we saw Betelgeuse going supernova tomorrow it would actually of happened like 640 years ago...

I know that don't really have much of bearing on the convo - cos well if it can still hurt us from 640 liight years away well were screwed - but nothing we can do about it now
