...Pinwheel Galaxy had a supernova explosion at approximately 21 million light-years away, the neutrino blast had been captured and it is bringing right now
~this Super Nova Explosion is visible with binoculars, located at the handle of the big dipper, between the last two stars and north in a equal lateral triangle point

Spica is about 10.25 Solar masses. A star above 10 solar masses can go supernova. The reason is does not on the list because is unlikely to explode, but still possible.The list only list stars that very likely to go supernova
@Battery9876 Supernovae are unimaginably bright. They can outshine their entire GALAXY. But i'm not sure how close it would need to be to match the brightness of the sun. Tens of light years perhaps.
Does this guy even read Wikipedia?! Spica is not even on the 'List of Supernova Candidates'
Also IK Pegasi due to the uncertainty in its stellar evolution could go off any time in the next million years .. that includes tomorrow.. and it would be a type 1a. At least the end would be very quick and very thorough.
Also if the supernova's axis is pointed at us the damage range is ~3300 Light years.
For a full report Google this: "Catch a Star! 2004" report-n
@FordPrefectification Although IK Pegasi is moving away from us at about 11 km/sec, SO if it went off 1.3 million years from now it would be about 200 away. Since its axis is not pointed at us it should be safe then.
Its mass is around 11 times the mass of the sun. So its border-line blowupable-that's a scientific term, "blowupable". haha i wish he was my science teacher!!!
There is an explination of the creation of Platinum in Wikipedia that states it is made in a "Quark star" a form of extreme Neutron star. If so, how does it get into the general universe, can neutron stars explode?
@SvenTviking no neutron stars are one of the aftermaths of a supernova platinum is formed in the supernova along with the other heavier elements such as gold,graphite,nickle and so on....
@BLACK420OPS I don't know if what they ment was that platinum was only made in supernova explosions of stars big enough to form "Quark stars". The definition for QS was one were the matter in the core degenerated beyond the nutron star level. Being made of a quark soup rather than nutron soup. If you see what I mean. Its wikipedia!
Suns are planet's core in their developmental stages. They're made up of gigantic spherical magnet that are inundated by a sea of ions which serve as the foudation of all chemical elements as they ascend onto different levels. Worlds don't explode, they simply disintegrate once their heat source depletes as gravity is an inherent component of extreme heat and matter is weightless.

I thought that White dwarf stars (what the Sun will turn into) were made primarily of Carbon, and it was the Carbon that creates the supernova. Could the increased temperature of the White Dwarf (due to the accretion of matter form it's 'sister' star) coupled with the fusion of the hydrogen (the part that was ripped from the sister star and accreted onto the White dwarf) cause a type of thermonuclear explosion (the supernova of the White Dwarf)?
hey i just wanted to say that i really appreciate all that you have done to help people out to undertsand complex science. it makes me wish i was a science man as well :p
Astronogers have little chance of successfully identifying "supernova candidates", since they don't understand the phenomenon. As for our sun "exploding", it absolutely could "go nova". This preposterous fable about stars "collapsing" and "rebounding" and "shock waves" is idiotic in the extreme. Supernova events are electrical in nature. Stars are lit electrically. "Neutrinos" have nothing to do with it. Stellar fusion is wrong. "White dwarf" is equally absurd. "Gravity" is irrelevant.
The nearest White Dwarf with a companion is the Sirius system. Is there any chance of a Type 1A supernova happening when Sirius A turns into a red giant?
Through the video I thought how you are saying that there are no dangers for the Earth or more directly from the SuperNova, and then you said that there are other things to worry about like Asteroid impacts and solar rays.
Like; Hey no worries mate, thats not going to destroy us, but Asteroids will!
Some people are going to take it seriously... I just LOLed when you said that...
50 ly statement seems off. Most articles i have read say substantial damage to our atmosphere can be done by directed energy quite a bit further. Up to 500ly. Anything beyond that we are safe. Beetlejuice will explode soon, its so far off though that its of no concern, and the projected direction of harmful energy will go another direction from us. It should be a sight to behold when it does go hyper nova.
This guy doesn't stick with his theme explanation. Instead he places paragraphs into paragraphs because he is extremely over wordy and thinks he is in a race to explain something. Did you hear him!
This comment has received too many negative votesshow
This overly wordy person placed so much more thoughts and sentances in his decriptions or definition and explanations you forget what the heck is he talking about.
It is my understanding that the gamma ray burst from WR104 would be pointed almost directly at Earth. Astronomers consider WR104 to be the biggest threat from another star.
Phil, one of the best explanations of the sequence of events for different types of supernovae. What really fascinates me is the hypernova phenomenon, which I've heard described by astronomers as the effect of viewing a supernovae in the line-of-sight of the focused energy release. I think they measure 10-1000X the energy of a normal supernovae.
there was an article I read once that stated that a super-massive star went nova and released a gamma ray burst that lasted a full half hour and it had the effect of sterilizing that particular galaxy, ever hear of that? This happened in a distant galaxy btw...........
your right, scottypants, I was making an assumption about life existing outside of earth. But that is more or less besides the point, I was trying to say that 1) supernovas can be very, very dangerous and 2) if thebadsastronomer is aware of this particular event.
Oh, and there has got to be life elsewhere, we're not made of special or rare materials and our star is a very ordinary star, one of billions, albeit very stable and long lived but there ya go.
Even at 10 times the mass of Jupiter, you'd still only get a brown dwarf, which some might call a 'failed star'.
You need atleast 20 times the mass of Jupiter (1/20th of the Sun's mass) before fusion can happen and sustain itself. And that would result in a very dim and boring star.
I believe it's 'loosely stated' that Jupiter is a 'failed star'. However, that's somewhat of a misnomer. Jupiter is no where near massive enough to generate the pressures (thus temperatures) to start the 'fusion reactions' that powers stars.
You are a very smart man. I enjoy your videos they are very informing. Betelgeuse is actually a real threat to our solar system and can go super nova at any moment scientists predict next 10-1000 years. And supernova's can cause devestation within a 500 light year radius with ejected particles from the alien solar systems
I thought that the fusion that takes place in a white dwarf (that creates the explosion), had to do with the fusion of Carbon? I thought that White dwarf stars were mainly made out of Carbon?
Yes, however the 'regular' star accretes matter onto the surface of the white dwarf (as the White Dwarf rips matter off of the regular star), thus increases its mass, raising its temperature to the point where carbon fuses. Then the white dwarf explodes. Right?
No, No, No. When a White Dwarf were to explode, it would create much heavier elements, Sort of like how really massive stars when they go supernova create all elements up to Uranium. This White Dwarf explosion would probably create around the Iron range. White Dwarfs on their own fuse to carbon, then settle into brown, dead, stars. Where fusion stops, and the heat is gone.
Actually, all the heavier elements are created by stars much more massive than our sun. G type stars, like our sun, leave a core behind after they go Nova (Nova isn't an explosion). If a companion Star is near by, the high mass of the Dwarf will 'rip matter off of it'. It will create an accretion disk around the dwarf, as matter accretes, it raises the temperature to the point were carbon will fuse, and explodes. It's called a type one Supernova (or Carbon detonation).
"...then settle into brown..." Brown dwarfs aren't stars, and never were. They are objects that are heavier than Gas Giants (like Jupiter), however, don't have the mass needed for hydrogen to fuse. 'Dead stars', like Neutron Stars (after they come off their 'pulsar stage') are created by Stars much more Massive than our Sun.
I'm not the science guy here, of course, but I can somewhat answer that.
You would not be able to see a star blow up in the sense of an explosion that you're probably thinking. It doesn't necessarily happen quickly, and plus, light takes a while to travel. (I love the concept that says that the light we see from stars is "old", so we're looking into the "past.")
If the star was close enough, you might be able to pick it out among the other stars of the sky, but a telescope might be needed.
When a star blew up in 1054, the "guest star" recorded by Chinese and other astronomers lasted for years. In fact, for a month, it was bright enough to be seen during the daytime! Google "Crab Nebula" for some more information.
Have you put much thought to the Gamma Ray flux from an Eta Carinea explosion on the tritium load surrounding the plutonium pits of nuclear devices? Gamma rays interacting with tritium produce LOTS of neutrons, thats why they are in bombs.
you know what the fuck heads who just spend their whole life Makeing fun of youtube videos. but the people who do that must have no lives and no girlfriends. this gut has some good information but you guys r too retarded to realize that hes very samrt and explaims some interesting point but you people are just to full of your own shit that you cant notice that, sooo JOG ON!!!!
Question: How close does a white dwarf have to be to an average sized star like our Sun to draw matter from it? And what's the average density of a white dwarf?
White dwarf stars has aboslutley nothing to do with shorter than average light skinned humans I assure you. My guess as to why they are called white dwarf stars if because They are white and small.
I guess rationalway and oreomonster01 have never heard or recognized sarcasm before. I think it is hilarious that they thought that kenwardgate was serious. Perhaps when they are introduced to the concept of sarcasm they will reflect on their comments and have a little giggle. =8~P>
You need to get a microphone with noise reduction, or enable noise reduction on your sound card's microphone setup. It's kind of annoying to hear the high-pitched background noise from your computer.
No, really, it's not a problem with my sound card or my drivers. It is admittedly a minor complaint, and really only a problem when I'm wearing headphones, but it is definitely there and not an artifact. It just sounds like a particularly noisy computer fan or hard drive in the background. Not a big deal, but could be corrected easily with noise reduction.
I've got monitor phones, pretty expensive ones, and they're good at playing all frequencies. I'm also running a Creative X-Fi card. Really, I'm thinking it's your card, or you may even have your system's equalizer settings thrown off. Using a C-Media or Realtek based soundcard? Set your sound control panel Equalizer to normal.
I always thought they said "Shawna" in Ferris Bueller. Jennifer Grey tells Charlie Sheen her name in the police station and in the background you hear..."Shawna" or "Shala." Either way, they both sound the same. By the way, my name is Shawna. HAHAHA!! Honest!
Many would debate that it is and many would debate that it isn't. There's a theory that the univers contracts expands contracts expands an infinite amount of times, but it's only a theory.
Good stuff as always Phil. What I am hoping is that we get to see a supernova go off that is visible to the naked eye (i.e. in our galaxy) "soon". I remember scientists talking about (wishing for) that in the PBS documentary about 1987b.
good to know that I don't need to worry about that, not that I knew it was somnething that might need worrying about...
that reminds me, one of my favorite Sci-Fi series (ringworld) had something about a sort of super-super-nova involving multiple stars or black holes in the center of the galaxy, would a chain reaction involving multiple stars like that even be possible, and, if so, would it be any more deadly from an earth perspective than the nearest potential supernova star blowing?
I don't lie awake worrying about stars blowing up, or solar rays, or comet impacts, because if anything happens that destroys the Earth I will be dead and incapable of being upset about it...
what do you, the blooper actually worked out okay, good improvization there...
Transitiving, it would be something longer. You could probably read at night by the light of a close supernova for weeks (thanks Sagan), it would be much brighter than a full moon.
An explosion like that should happen at about once every 100 years or so in a galaxy our size, but we have been unlucky: none has happened in our galaxy since the telescope almost 400 years ago (thanks Galileu)
Phil! Thanks for everything. My son is 8 years old and we both appreciate your videos. Not only you explain well for the "common" ones, but you do it nicely. Keep up the good work! Keep us curious without ALL the answers. Let us search for even more. You are an asset to science, heck, to society!
Well, a white dwarf technically IS a star. But the deal with white dwarfs is as Phil explained, when they absorb enough mass, they go supernova (type 1A I believe).
yea, i understand that, but if there were not enough mass to make it explode but enough mass to make it larger, or kickstart a fusion reaction then stablize. just wondering about possible possible star birth scenerio
Actually, that's a very good question. I wondered that myself many years ago. Then astronomers found a star that really looks like it used to be a white dwarf. Totally bizarre. I have no idea if that was ever confirmed. Maybe it got enough fuel to kick start it again. Or maybe it was a totally wrong interpretation. :-) I should ask my friend who found it...
Too bad that they're that far away, why couldn't Spica have blown up 260 years ago.

I have a question.
If I was out watching the night sky, does it explode fast enough to be able to see it happen? And would it stand out?
stevoisme 2 years ago
I'm not the science guy here, of course, but I can somewhat answer that.
You would not be able to see a star blow up in the sense of an explosion that you're probably thinking. It doesn't necessarily happen quickly, and plus, light takes a while to travel. (I love the concept that says that the light we see from stars is "old", so we're looking into the "past.")
If the star was close enough, you might be able to pick it out among the other stars of the sky, but a telescope might be needed.

Yes.
We are talking about a bomb bigger than the Sun.
It's really hard to wrap your mind around the amount of energy produced.
Such an event would be spectacular.
You'd be able to see it during the day.

When a star blew up in 1054, the "guest star" recorded by Chinese and other astronomers lasted for years. In fact, for a month, it was bright enough to be seen during the daytime! Google "Crab Nebula" for some more information.

Have you put much thought to the Gamma Ray flux from an Eta Carinea explosion on the tritium load surrounding the plutonium pits of nuclear devices? Gamma rays interacting with tritium produce LOTS of neutrons, thats why they are in bombs.

Isn't Sirius around 8.5 lightyears from us...? What if that blew up?...can it?
CaptainDistracted 3 years ago
Sirius A is only twice the size of the sun too small to explode, Sirius B is a white dwarf about the size of earth also too small to explode.

When you said Blows Up, I got lagg and heard only blows.
Oh and then the series "Supernova", is fake, cuz the sun can't explode.
Anywayz, if you're a star and you get close to sun, you say "He-he, you can't explodee".

Question: How close does a white dwarf have to be to an average sized star like our Sun to draw matter from it? And what's the average density of a white dwarf?

Kenwardagte-
White dwarf stars has aboslutley nothing to do with shorter than average light skinned humans I assure you. My guess as to why they are called white dwarf stars if because They are white and small.

You need to get a microphone with noise reduction, or enable noise reduction on your sound card's microphone setup. It's kind of annoying to hear the high-pitched background noise from your computer.

Ehmm, I dont hear any high pitch noises... It sounds like your sound card may have issues, or you may need to update your codecs.
vharshyde 3 years ago
No, really, it's not a problem with my sound card or my drivers. It is admittedly a minor complaint, and really only a problem when I'm wearing headphones, but it is definitely there and not an artifact. It just sounds like a particularly noisy computer fan or hard drive in the background. Not a big deal, but could be corrected easily with noise reduction.
saintaureus 3 years ago
I've got monitor phones, pretty expensive ones, and they're good at playing all frequencies. I'm also running a Creative X-Fi card. Really, I'm thinking it's your card, or you may even have your system's equalizer settings thrown off. Using a C-Media or Realtek based soundcard? Set your sound control panel Equalizer to normal.

I always thought they said "Shawna" in Ferris Bueller. Jennifer Grey tells Charlie Sheen her name in the police station and in the background you hear..."Shawna" or "Shala." Either way, they both sound the same. By the way, my name is Shawna. HAHAHA!! Honest!

Many would debate that it is and many would debate that it isn't. There's a theory that the univers contracts expands contracts expands an infinite amount of times, but it's only a theory.

Good stuff as always Phil. What I am hoping is that we get to see a supernova go off that is visible to the naked eye (i.e. in our galaxy) "soon". I remember scientists talking about (wishing for) that in the PBS documentary about 1987b.
eric67t 3 years ago
good to know that I don't need to worry about that, not that I knew it was somnething that might need worrying about...
that reminds me, one of my favorite Sci-Fi series (ringworld) had something about a sort of super-super-nova involving multiple stars or black holes in the center of the galaxy, would a chain reaction involving multiple stars like that even be possible, and, if so, would it be any more deadly from an earth perspective than the nearest potential supernova star blowing?

what do you, the blooper actually worked out okay, good improvization there...
Transitiving, it would be something longer. You could probably read at night by the light of a close supernova for weeks (thanks Sagan), it would be much brighter than a full moon.
An explosion like that should happen at about once every 100 years or so in a galaxy our size, but we have been unlucky: none has happened in our galaxy since the telescope almost 400 years ago (thanks Galileu)

can a white dwarf absorb matter and form a new star?
cozmikzen 3 years ago
Well, a white dwarf technically IS a star. But the deal with white dwarfs is as Phil explained, when they absorb enough mass, they go supernova (type 1A I believe).
CousinoMacul 3 years ago
yea, i understand that, but if there were not enough mass to make it explode but enough mass to make it larger, or kickstart a fusion reaction then stablize. just wondering about possible possible star birth scenerio

NDF211Gunner 1 year ago
Actually, that's a very good question. I wondered that myself many years ago. Then astronomers found a star that really looks like it used to be a white dwarf. Totally bizarre. I have no idea if that was ever confirmed. Maybe it got enough fuel to kick start it again. Or maybe it was a totally wrong interpretation. :-) I should ask my friend who found it...
