VY Canis Majoris: Largest Star in the Universe (Fact of the Day)

Size of VY Canis Majoris compared to our Sun
The largest star yet discovered in the Universe is VY Canis Majoris (VY CMa). It is a red hypergiant star located in the constellation of Canis Major. It is about 2000 times the size of our Sun with a diameter of 3,063,500,000,000m. If this star replaced our Sun in the Solar system, it would extend up to Saturn. It is about 4,900 light years away from Earth. The surface temperature of the star is comparatively cooler than our Sun with 3,000K compared to our Sun's 5,800K.

  6. When it goes "bang", the explosion won't reach us. It's too far.

  7. True, the life age of this star is unkonwn but due to its size it is likely it has not died just yet considering we can see it within the 4,200 LY distance - meaning it would have to have died (exploded) at least 4,200 years ago from today to make it appear to be dark or cold or dead. It is most likely living millions of years and a 4,200 year period is very short compared to millions of years.

    True again, we are all very small in fact, but comparing our size to a large sun, any sun, our sun, or the largest is like comparing an ant's toenail having enough energy to scratch us when we are the size we are.

    Yes, VY Canis Majoris is very large but pales in comparrison to the vast emptiness of the space around it in it's own solar system, much less smaller than it's own galaxy, and just an "ant's toenail's bacteria" (the microscopic stuff on an ant's tonail) in size to the Universe (well, actually much, much, much smaller even than that).

    Will it affect us, yes, but we will not notice it for 4,200 years at a minimum if it died today and so minimally that we might just hear about it online or by some other message IF we care to notice "another star" died today. Gravitational pulls will be affected locally around the star and it's galaxy may be affected minimally, but that would never affect us beyond maybe us reporting the "light went out."

  14. No, god didn't make this. Let me explain you something.
    A long time ago people didn't knew how things happened, so they thought someone above their heads did it. Someone almighty. Now people are a lot smarter (most of them) and there is nothing above their heads it is just nature who did it.

    DON'T ask me how because I don't know that ask a scientist, but no, your god didn't make this. You are too blind to see this, your arrogance is too big.
    I have respect for people who believe in god, but it just doesn't make sense.

    1. Yea go ask a scientist about how perfect mathematically speaking our tiny universe is and then think a while about God again

      Delete
    2. "Perfect mathematically speaking"? Wrong again god fearing primitives. Even if the phrase mathematically perfect didn't make me love out loud and was a real thing it would still be a flawed statement as nothing in the universe would qualify. Planets aren't perfectly shaped. Not perfect spheres or perfect ellipses. Same goes for stars, comets, clusters galaxies or our universe. This was something once thought by the bronze age goat herders who write the bible. It would be better for you jesus-freaks to stay quiet and let people think you are idiots instead of opening your mouths and leaving no doubt.

    3. God? Hahahahaha, what a joke! People who use their brains know that "god" is for ignorant people.

      Delete
    4. To say that god doesn't exist is as wrong as saying he does. There isn't a way for humans to know such things, therefore we should accept that we don't know and it's okay not to know. What we can wrap our minds around seems to fascinate us and that is enough.

  15. I myself am a christian who struggle to believe how all of this was made. Whether by God or by nature, I cannot understand or believe completely this all just happened by chance. Hard to think about as it just does not make any sense to me.

    2. If God was to explain the universe to someone, it would be like trying to teach an ant the Internet. No one can fathom how God made this all. If you want to accept God it your heart and live eternally up in Heaven, say this prayer: God, forgive me for all my mistakes, thankyou for always watching out for me. I accept you into my heart and I will follow you now and forever I will put u first in my life forever. Amen

    4. Who created god anyway? Oh, he was always here you say. Then so was the universe and its laws that govern it. There are no gods except in the minds of the weak who can not overcome their own drive for self-preservation.

    1. Wow, that shows almost no understanding of the universe in which you inhabit. Not even 1%? This sun is about 0.00032 light years in diameter. That makes it about 0.00000032% of our galaxy. There are billions of galaxies separated by millions to billions of light years. Not even 1%? Why are so many idiots on this site?

  18. So many idiots indeed, and not just on this site they/we inhabit the world

  19. Believing in God isn't ignorant; people didn't just say "I don't understand how the universe works, so I'll chalk it up to some higher being".(Well, maybe some did) But God walked and talked with people. I wish I could help people understand, He isn't going to show proof of His existence until you take a leap of faith. There are so many wonders in the universe, and our little world, it is hard for me to understand how people can think it all just spontaneously happened without an intelligent creator. However, even if you don't believe in Him, there is no need really to tear other people or their beliefs down.

  20. Amazing people angry and upset about VY CANIS MAJORIS.ITS HARD TO REAF 10 REPLYS WITHOUT SOMEONE INSULTING SOMEONE ELSE OR GETTING OFF TRACK OF THE TOPIC. ITS A HUGE STAR AND THERE ARE LARGER STARS WR CAN'T SEE YET AND I CANT WAIT TO SEE MORE INFO ON LARGER STARS. IF ANYONE HAS MORE INFO ON IT PLEASE POST.
    SEE CULTURES WERE BUILT ON US GETTING ALONG AND BUILDING.ITS LIKE A IMPROV EXERCISE. YES AND ADD SOMETHING POSITIVE.

  21. I wasn't so concerned about the "idiots" on this site as I was about the snobbish rude elitists who think they know everything. It's one thing to know that somebody doesn't understand something, but it's far worse IMHO reading the rude comments of those who think they are smarter and civilized. I think they are in the bronze age of manners. And maybe need a smack across their egos.

  24. It takes someone without sociopathic tendencies to submit to the fact that there are inexplicable things out there, things we cannot process in our minds. There are facts about these stars and the guy bashing Christians probably copied and pasted the facts in his rant from google. Probably just some sweaty fat guy who took the time from Internet dating/porn site to vent and toot his own horn a little bit. KEEP FLEXING THAT GOOGLE MUSCLE BUDDY!!! Sir Cheeto

  25. Funny...almost all of the greatest minds that formed our understanding of the universe today believed in God in one form or another... Galileo, Newton, Einstein.

    For you folks that state belief in God is ignorant...then I dare you to publish your theories of the universe since you are obviously smarter than the greatest minds of our tiny existence.

  27. It is so obvious to everyone who is not an American. They are individuals who have yet to take their heads out of their asses for the last two hundred years or so to realize that what we did in that amount of time, most everyone else hasn't done in 5000 years.

  30. God was an alien. Do you think we just developed out of monkeys? No, our DNA was manipulated, first with Cro magnom man, then homo sapiens. The rest of the universe is still to be understood how the god particle actually came to be (via the big bang theory), but they're getting closer to figuring it out.

    ReplyDelete
  31. I just can't imagene how large this star is. Unbelivalbe :S

    ReplyDelete
  32. It is not Cro magnom; it is magnon. It feels foolish to even attempt to engage somebody who believes that god was a god damned alien though. Here's a thought: anyone who seeks to discuss scientific theories which require sufficient education to even personally comprehend, much less discuss on a remotely intellectual level, should try bothering to learn something about science beforehand. Yes, there may indeed be a god or some alien intervention, but seeing how little reputable evidence exists for either, why not take the time to learn about theories for which there is evidence? You will find that your superstitious needs will recede as your understanding of actual astronomy, cosmology and physics increases. It's sucks not knowing but the quest for truth does not draw nearer with people wasting their minds on nonsense.

  36. I find it rather odd (and sad for that matter) that religion has to make its way into every conversation. Does this view of the world have to permeate every aspect of our lives?

    Are we as a people simply incapable of separating our our political and scientific views from the metaphysical/religious aspects of our lives?

    I really hate that about us as a people. Not just Americans (of which I am one) but our entire race.

    To me, there is no more divisive topic than that of religion. Nothing can close us off to our logical, free-thinking mind faster than the simple fact that someone prays to a different mythical figure in the sky.

    I'm not saying religion is bad per-say. Just that it's yet another obstacle thrown in our way.

    The moral and ethical code found in religion served its purpose. It managed to get us through the Dark Ages and allowed us to evolve into a more civilized race than was otherwise likely to happen.

    I just wonder if the close-minded intolerance that religion tends to garner for those that don't follow the same teachings - or for those that follow no teachings at all - doesn't counter-act its usefulness.

    If we could keep our spiritual views to ourselves, or in the proper venue such as a church or temple, none of this would ever be an issue.

    Alas, this hasn't ever been the case in the thousands of years since its inception, so why would it start now.

    Its so sad that we can be so smart, yet so ignorant and stupid at the same time. We are almost a living, breathing contradiction.

    Perhaps we aren't as evolved or intelligent as we like to think we are after all......


    PS.......I just wanted to read about this big ass freakin star and I had to get into this stupid crap. Thanks for f*cking up my reading time!

  37. For most great scientists like Einstien or Newton, God is the only explanation, so all you 'athiests', don't call us ignorant.

    ReplyDelete
  38. Newton you can claim, but Einstien wasn't religious. He was a Jew in culture only, not religion. Except for a year long period in his youth where he did practice the religious aspect of the Jewish faith.

    And I wasn't saying that if you believe in a God/higher power that you are ignorant. Far from it. I'm from a religious family myself.

    Just that SOME of the people who believe, blindly follow and never question. And yes, that IS ignorant.

    Believing the world is only 10,000 years old when there is scientific fact showing that it is over billions of years old is ignorant.

    Follow my logic?

    Not bashing religion. Just pointing out that some of those that practice it need to open their minds to things outside of the Old and New Testaments.....

  40. Not to inflame the issue, but I for one believe in God. I also believe in science and am fascinated by the observation and mathematics and logic that go into so many of these fantastic theories that try to make sense of the universe.

    Yes, I believe in the Bible, but I doubt that the Earth was actually made in a period of seven days, or is literally only 7,000 years old. God gives us certain things in terms we can wrap our heads around through either simplification or metaphor; "us" being the ancients, or even a child. Metaphor is the best way to describe these, initially. And really, knowing the absolute truth about evolution or the creation isn’t necessary to our spiritual lives. The rest is left for us to try to figure out on our own, so we can learn how to utilize and expand our mental capabilities.

    As shown by this fantastic star, the universe is unbelievably complex, often outside untrained comprehension. It's extremely close-minded of both the religious and the non-religious to make deity a being of face-value, to claim as either completely true or completely false.

    As said above, "Believing the world is only 10,000 years old when there is scientific fact showing that it is over billions of years old is ignorant." I agree. But it doesn't make the Old Testament false. Is an allegory a lie? Is simplification wrong?

    One shouldn't get angry at those who refer to Baroque and Romantic-era music as "Classical"; it's far simpler to classify a genre under one name. By the same token, one shouldn't blindly believe that Baroque and Romantic music ARE absolutely Classical, simply because that's what they're referred to most of the time.

    God works in mysterious ways. We figure out what we can, theorize the rest, and make use of the reasoning powers God gave us.

  44. This is very wrong! VY Canis Majoris was not the largest star! It was only 6th! The real largest star is NML Cygni, 1,650 times the sun's radius! Compare it to VY Canis Majoris' 1,420 solar radii, and you will see what I mean.

  48. You. People. Are f*cking uneducated, uncultured, closed minded, ignorant, saddening, depressing wastes of matter. Some of you, are absolutely absorbed in your "science vs religion" bullsh*t. Others are pure and alright, and they deserve a gold star for being open minded and compassionate, which is how the world should be ruled, just the most effective and understanding possibility. But besides that, your arguments are repugnant excuses for dominance and belittling. You make me so sick I want to kill myself. I have now officially, OFFICIALLY, lost my faith in humanity.

  51. Hello Aaron Chavez. You make me laugh. At you. You go on for ages telling the whole world how sick of humanity you are, and how uneducated we all are, which would make me assume that you think you are educated and therefor are 'better' than the rest of us. You also say that that, "Others are pure and alright, and they deserve a gold star for being open minded and compassionate, which is how the world should be ruled, just the most effective and understanding possibility. But besides that, your arguments are repugnant excuses for dominance and belittling" So where does that put you? You are one of the people posting comments so that you can swear and complain about the word online, which is what you are complaining about! And yes, I do know that I am complaining as well.

    P.S. If you ever read throught old comments and you see this one, and you want to respond, you can,
    a) ignore your irrational urge to respond
    b)never look at this site again
    c) smash the device you are using to look at this site
    d) Use the name 'Blinchy' to get me to answer
