VY Canis Majoris is supposed to explode within 1 million years. When it does explode, and if it turns into a black hole, we most likely will be sucked in because its only 4500 light years away, which is like a next door neighbor comparing how big the universe is.
@ClubPenguinMovies123 Uhh...no. Firstly it's 5000 LY away, and secondly the gravity of such a "small" black hole is neglible at this distance. It's in fact just 30 times stronger than that of the Sun. The Black Hole will have much less gravity because in the event of VYCM going supernova, or hypernova, a lot, and I mean a lot, of its mass is going to be ejected.
I'm just really wondering how much actually astronomers know about such massive stars and phaenomena, like hypernovae to make safe assumptions of their future and how they would affect earth.
It's gonna be nothing I bet, still the rarity of these events in the universe makes me worry a bit about how accurate any predictions can be.
@AAMMLfan you should say 7000-8000 years ago not light years ago.bcuz light year describes distance not time.(1 light year=distance travelled by light in time 1 year)
This hypergiant has already exploded 3 times. First of those bursts had appeared in 7th millennia B.C.E. and the light was seen on Earth in 2nd or 1st century B.C.E. Then was another burst, in 42nd century B.C.E., which was seen on Earth in 1843 C.E. And then it has undergone the final tremendous explosion, similar to the 2006jc supernova. Light from this tremendous burial will be seen on Earth in 2030 or later...
If Eta Carinae dies in a supernova blast in our lifetime, wouldnt it of already happened? considering it is 8000 light years from the galaxy, meaning if we see the event happen we would be seeing it exploding 8000 years ago. just a thought...
yes the explosion happened around 8150 befor J.C., but we've been able to look it in 1850 when the light, gamma ray, x-rays, comsimc rays, radio waves, etc, reached us.
Absolutly beautiful...this is why I wanna become an astronomer...to be able to gaze out into the skies and discover new worlds and galaxies and stars and planets and black holes ect. Ect.
So if we see it explode tomorrow, it means the explosion actually already happened 7000-8000 light years ago? That's incredible to even think about...
Exactly. What's crazy to me is if we zoomed in on an alien planet that's 20 LY away and saw an alien walking down the street, it means that technically he isn't walking down the street right now, but then again he is walking down the street right now because that's what we're seeing. Time is relative to your position, that's the reasoning and beauty behind Einstein's theory of relativity. It's mind-boggling if you think about it. The universe is an amazing thing.
right! now you know why we are not really here. If your comment is correct which we assume it is then Events on this planet seen from further down the big bang pipeline have already happened. We are already gone my friends. What is happening has already happened. Ahh space time what a concept.
@licxstar Actually no, we only look back upon things that are very far away, because light cannot travel any faster than 300,000 kilometres per second. Since our planet is at a distance of '0' from itself, the light would not need to exceed its maximum speed to reach anywhere on earth, we are looking at a precise here and now moment of what is happening on earth. Depending on how you look at it however, we may be 8 minutes behind ourselves (the time it takes light from the sun to reach earth).
@AAMLfan Hi! I think that if we see it tomorrow we would never feel the energy or the blast it would emit at the moment but maybe 7000-8000 years from now the ppl in earth might feel something... what do u think??
go change an article in wikipedia, and see how fast it gets changed back, Wikipedia is heavily moderated and any false information won't last for more then a few miniutes
Sirius is alot closer to the earth (8.6 light years) compared to Eta Carinae which is some 7000 light years away from the Earth. Which is y Sirius seems more brighter in the night sky.
Sirius is, in fact, the brightest star in the sky from our viewpoint. This is due to a combination of it's luminosity AND it's proximity to our own sun. That is, of course, completely relative and Sirius doesn't rank as high as you've been led to believe among the most luminous stars in our galaxy.
Sirius is only an A-type main sequence star (about 17 times the luminosity of the sun) while Eta Carinae's high mass main star has a peculiar spectrum due to its high rate of mass loss and is >1000000 as luminous than the sun across all wavelengths. Also the light from Eta Carinae is absorbed by dust and gas along our line of sight by about 90%.
stop saying that... the earth is protected from gamma rays by the atmosphere, as well from some other cosmic rays by the magnetosphere. The ISS might get toasted. if its still up there in 7500+ years!
Unlikely, King. While our atmosphere does protect us from a great many things, it is our magnetic field that protects us from cosmic radiation. The magnetic field cannot be stripped away by a large burst of radiation even if such a blast were to hit us. Worst case scenario is more likely that the objects we have in orbit are damaged or destroyed and our communications are disrupted for a little while. Also, I really wouldn't worry about it happening in your lifetime ;)
Sinjinator, the radiation flux will be so great that at least half of planet Earth will be STERILISED of all lifeforms. If the jet aligns with Sol, were fucked.
What you explained are the effects caused by non-jet radiation wich could still fatally damage earths atmosphere. It could even go nova in the next few years. You could read a book at night!
Eta Carinae is probably too far away, at 7000 light years, to pose a threat to Earth but if it does go, then it will be a most spectacular natural fireworks display and I'll be buying a plane ticket to the Southern Hemisphere somewhere to go and see it!
Breathtaking. Serves us right for not living in the southern hemisphere, that we don't get to see this. Music is perfect to look at this humbling and beautiful sight.
If the star Beteljuice went supernova, it would be twice as bright as the full moon.
