[@ianmeade7441]

Scientists have said that the hyper nova created in the death of VY Canis majoris will be so huge that it will outshine the moon at night, and almost look as though the earth orbits two stars. Imagine if it were to leave a black hole, it would be "visible" from earth! (The best target for backyard astronomy ever)

[@AmY-gm2qs]

Ian Meade Your comment made me so happy just now Ian

[@ianmeade7441]

What I'm getting at is that the signal of the stars death could announce itself any day now

[@dustinchisam79]

actually black holes are invisible unless they are feeding. They're black and only 3 to tens of miles across.

[@ianmeade7441]

Not always. Keep in mind that VY Canis majoris has a much larger schwarzschild radius than most stars, and black holes are not invisible. Sure we can't directly see them, but we can see the great black ball of where they are, not to mention a rapidly spinning accretion disk they create. Even if the the black hole itself wasn't visible from earth, the disk would be, and that's still pretty cool to look at.

a simple technique called spectroscopy, where we can read the spectrum of a star reveals something called absorption lines, these lines tell us what elements are common in any star that can be observed either by the naked eye, or by telescope, recent advances in this technique have allowed us, where we know planets exist around other stars, to separate out the spectrum of the planet from that of the parent star to assess the atmosphere of the orbiting planet.

[@ReconissanceMa]

I think that knowing more about the universe heightens our self-understanding. I do agree with you that they can't keep spending money like this, however if we didn't have these things we would never know how vast and complicated everything is. When we look at the odds of sophisticated life we find that the odds are astronomical, it is ironic that something so common is something so beautiful. When we start to value everything that we know nothing about then can we truly value our existence.

[@mysterygamermgclues8864]

[@JayakrishnanNairOmana]

How do we know that it has not already exploded, given that it is 4600 light years away (and what we are observing today is how it used to be 4600 years ago)? Isn't it possible it already had the hypernova nearly 4600 years ago and therefore the gamma rays can hit the earth any moment? By the same vein, if a hypernova explosion happens in our galactic neighborhood, wouldn't it be that we can get almost no advance warning (other than that a star is ready to explode) before the stream of gamma rays suddenly hits the planet and wipes out all life?

[@PiperTMTotalWar]

+Jayakrishnan Nair Gamma Rays will travel at the speed of light, so if the Ray is infact pointed in our direction then yes we would get not advance warning. There is still some debate of the exact nature of this risk, if indeed there is risk at all. Piper

[@sinsforeal]

+Jayakrishnan Nair Yes it is very possible that the star could have already exploded. But we won't know until 4,600 years after the fact.

[@L2speel]

AKA the The Alcubierre Drive. It takes advantage of a quirk in the cosmological code that allows for the expansion and contraction of space-time, and could allow for hyper-fast travel between interstellar destinations. Essentially, the empty space behind a starship would be made to expand rapidly, pushing the craft in a forward direction - passengers would perceive it as movement despite the complete lack of acceleration. For further information I suggest looking it up yourself.

It's classified as a yellow dwarf star. All because when you squint at it during the day and it looks like a bright white light, doesn't mean it's white.

[@tholc21]

MrHalo32009 I mentioned the Sun as a yellow dwarf to my astronomy professor and he rejected it. Haha

[@BaseCu327]

MrHalo32009 No, the sun is yellow because the sky changes the wavelength of the sun's white light. If you were in orbit or on a body with no atmosphere you'd see the sun as white.

[@PSmith5194681153]

Mass and volume are different matters. This means that VY Canis Majoris is much less dense than the sun. If they had equal density, then the mass and volume differences would be equal. The formula is mass = volume x density (you can use algebra to rearrange the variables as you see fit). I hope this clears up your confusion.

The reason for VY Canis Majoris's instability has to do with the complexity and rapidity of it's internal convection.Unlike red dwarves,which have the most simple and relatively slowest convection processes.And therefore the longest lifespans.Hypermassive stars like VY Canis Majoris have complex multiple layers of convection all ongoing simultaneously.And have cores that enter the helium burning phase most stars undergo at the end of their lifespan far earlier owing to their incredible mass and internal heat and pressure driving the conversion of hydrogen to helium phase.

[@Sean_735]

The Sun's core is ~15,700,000K, it's photosphere(surface) is about 5,788K, and it's corona(atmosphere) is about 5,000,000K. As an astrophysicist, I say this on behalf of me, and all my colleagues; Please use Kelvins when talking about intense temperatures not found on Earth. The conversion from Celsius to Kelvin is really simple; K = °C + 273.15. So 0 °C = 273.15 Kelvin.

[@jackyborchtlombeek456]

Whether a star goes nova or not , whether it leaves behind a black hole or neutron star depends on it's mass and metallicity(how much of the star is made up of heavier elements). For instance a star the size of CM could leave behind a neutron star if it's metallicity was very high. Current tables/models show Canis Majoris will leave behind a black hole after it's gravitational collapse.

Also about your thing with temperatures, I know that the Kelvin scale is like that. He talked about Celsius, which means I responded in Celsius. I didn't even think of Kelvin when typing that. *back to Betelgeuse and VY Canis Majoris* It honestly doesn't matter if they've already exploded or not. In a few more years, we'll have even more high quality observations of the stars, and we'll find out more accurately their sizes, more accurately each year. So sending a spacecraft wouldn't be an idea.

VY Canis Majoris is the biggest star known in the universe so far and has radius of 2.000 Suns so it would reach aprox. to the Saturns orbit. When it explodes, it creates supermassive black hole and would be visible on the night sky with the same brightness and size of a full Moon.

[@vrosx-spythecheesewedge8218]

Actually VY Canis Majoris isn't as close to undergoing a Hypernova as close as Arcturus is. VY Canis Majoris is actually going to undergo a Nova soon, but Arcturus as we know it, will cease to exist becoming a black hole.

[@GMBlunderfish1]

Technically, a hypernova is called a pair instability supernova, and it will leave no remnants as the core will be completely disrupted.

[@Sean_735]

Betelgeuse is about 1/3 to 2/3 the diameter and about the same mass as VY Canis Majoris. It's not the second biggest star out there, but it is extremely similar to Canis Majoris in almost every way except size and color.

[@Everton97]

Technically it Vy canis Majoris has shed over half of its original mass and size. NML Cygni is the Largest at the time but VY Canis Majoris Hold the spot for largest so far. Don't get me wrong There may have been others that were even more massive ,however, These were the ones in which we have discovered.

[@irllcd13]

The thing that's really wierd to think about is that if VY went nova today, we wouldn't even know for another 4,900 years. Likewise, it could have gone nova 4,899 years ago and we wouldn't know untill next year. It could have gone nova when the pyramids were being built.

[@paideguinha]

Right now there is a new star called Westerlund 1-26, 1951 - 2544 times the sun radius, that may be incorrect though.

[@NLwino]

There is a limit in how big stars can get. The larger a star, the more it damages it self, the shorter the life spawn of the star. If too much matter tries to cluster, it will implode under it's own weight, before it can become a stable star. But there are without a doubt larger stars then Canis Majoris out there.

[@91zboy]

This is true but keep in mind that the light astronomers are viewing of this star is from the year 2887BC. It is possible that this star already went supernova thousands of years ago, it might not even exist anymore and we still wouldn't know because we are viewing light from so long ago. Much of the stars and galaxies we view today are not how they really appear.

I have a question. Supernovas give birth to neutron stars and black holes correct? And the mass of the star determines whether or not the supernova results in a neutron star or a black hole correct? And VY Canis Majoris is in the top 3 largest known stars correct? If VY Canis Majoris is in fact NOT massive enough to spawn a black hole at its demise then what is? And have we ever seen the birth of a neutron star or black hole?

[@mrkiky]

VY Canis Majoris is big but not really that massive. It has a very low density. UY Scuti is estimated at 1700 times bigger than the Sun by diameter but only 30 times heavier. There are stars out there 300x heavier than the Sun, but only 30 times bigger by diameter. Now that's an Ubernova I wanna see!

The reason I came here is because is Betelgeuse supernova-ers it will light up night so much it would look like a slightly dimmed day. I came here to see what it would look like if the Largest known star's hypernova would be more or less visible

[@Dirrly]

Remember... Mass is not the same as size... the star with the most known mass has a size of about 35x the radius of our sun. The mass is 265x the mass of our sun. In relation to that VY Canis Majoris is much larger. About 1400-2100x the radius of our sun. But it has "only" 30-40x the mass of our sun. So VY Canis Majoris lost 1/2 of his mass, but thats not 1/2 of the size. ;-)

the approximate diameter of vy canis majoris in miles is 8,000,000,000,000,000,000 or 8 quintillion miles in diameter which is larger than how far away it is (28.7 billion miles) when earth is only about 8000 miles in diameter, its a cool star compared to our sun, not as bright though, its amazing how small we are yet its only a hypergiant in the billions that are out there

@stormseeker442 yes it is, dylanh88 was wrong. VY Canis Majoris is well within our galaxy.

The problem is that the scientists have problems to define the surface of such stars. The density of this star is a thousand times less dense than the atmosphere on Earth. Because of the strong mass loss it is not sure if the outer layers of the star are still gravitationally bound to the star. So it´s very difficult to say it is exactly this large.

My favorite star

Now, I'm terrified and aware of the supernova & hypernova destruction.

When you think of the fabric of space time you can imagine it as a 3d fabric. When a hole is cut out of it, it does make a sphere but it is also a hole.

R136a1, the primary, is the most massive star ever discovered. Most massive meaning it is the heaviest. VY Canis Majoris is the largest in terms of girth or diameter which is 2,100 solar radii. R136a1 is only 35.5 times as wide as the Sun while it may be 265 times as heavy. On the other hand, VY Canis Majoris is about 40 times as heavy as the Sun making the density of this star even thinner than that of the Earth's atmosphere...

vy canis majoris is one of the most largest star discovered but R136a1 in large magellanic cloud is the most massive and luminous star ever discovered
