- grooviekenn, on 10/12/2007, -2/+49I'm still having a hard time grasping the actual size of Antares!
- leighhalliday, on 10/12/2007, -4/+39Maybe insignificant in size... but does size really matter? I would like to see that monstrous sun ride a bicycle, read a book, or paint a picture. Hah, I laugh at its incompetence.
- Agraek, on 10/12/2007, -0/+32It makes you feel quite... insignificant.
- RadiantBeing, on 10/12/2007, -5/+33I can't look at Antares without getting a little nauseous and tingly. I hope humanity's descendents suck all the energy out of Antares to power their futuristic SUVs and air conditioners... just to spite the universe.
- ekeup, on 10/12/2007, -0/+23Yes, the big ones are much cooler... here's a graph showing the differences in star classifications:
http://www.bramboroson.com/astro/images/hrdiagram.jpg - mc7winkie, on 10/12/2007, -0/+20I'm amazed at how physically large these stars actually are.
- LemonHerb, on 10/12/2007, -1/+18Try clicking both links and seeing the difference before you overflow with righteous indignation
- dbre2, on 10/12/2007, -2/+17uranus is huge in comparison
- kdehead, on 10/12/2007, -0/+14very cool.
protecting them as 3d "balls" , rather than the usual 2d size comparison, seems to make it more realistic/understandable.
although, i'm finding it very difficult to fathom the size of Antares!! - inactive, on 10/12/2007, -0/+12From what I can remember (not very much) the big huge ones like that are actually cooler than smaller ones
Can anyone comfirm that? - vertinox, on 10/12/2007, -1/+12"Maybe insignificant in size... but does size really matter? I would like to see that monstrous sun ride a bicycle, read a book, or paint a picture. Hah, I laugh at its incompetence."
Hrm... Strangely enough, I just saw a report on CNN about Antares changed course and is heading straight for our planet.... Which strangely enough is the same time you made your post. - chicken101, on 10/12/2007, -0/+10You could fit like 100 million earths inside of Antares.
Now think that there are trillians of visable stars in the universe. This place is huge! - kevincupp, on 10/12/2007, -1/+10An astonishing thing to look at is the distance between the planets. There was an episode of Bill Nye where they had Sun be one meter across, and then tiny model planets to scale based on the Sun. So the spread out the planets based on the proportion of the model, and the whole solar system ended up being about 4 kilometers long. Kind of the same idea as the 11-mile web page posted earlier.
- UNL1M1T3D, on 10/12/2007, -0/+9I think I remember that episode. Bill Nye rocks.
- fnaqzna, on 10/12/2007, -1/+10It would be nice to see the size of Sol's planetary orbits relative to Antares.
- SonnyW, on 10/12/2007, -1/+10If he took 6-7 days to make just the earth, I wonder how long the rest of the universe took...
- Alegis, on 10/12/2007, -1/+10I'm wondering how FAR antares must be from the earth if we can't even see it properly in the sky.
- banjokazooie, on 10/12/2007, -4/+12EDIT: Sorry, I goofed. You can bury me now.
- Geekkake, on 10/12/2007, -1/+9Just in cae you'd forgotten about your complete irrelevence in the cosmos...
- liquidedge, on 10/12/2007, -0/+8Where the hell did they find a table that big?
- eridius, on 10/12/2007, -1/+8The last one that showed up stayed within our solar system. Yeah, it had "better" renderings, but as it was limited to our solar system it didn't teach us, for example, how ridiculously huge Antares is.
- Alegis, on 10/12/2007, -0/+6Antares ...
That's no moon - inactive, on 10/12/2007, -0/+6@ Alegis
It's actually one of the brightest
"Antares (α Scorpii / Alpha Scorpii) is the brightest star in the constellation Scorpius and one of the brightest stars in the nighttime sky." - Wiki - kundalini, on 10/12/2007, -1/+7This article is completely irrelivant due to the inability for it to point out what role Xenu has in the diagrams.
- Matteos, on 10/12/2007, -1/+7My anus is not large at all.
- flightvector, on 10/12/2007, -0/+5It is most likely right; keep in mind that if Jupiter's volume is 1300 times that of Earth, that doesn't mean 1300 Earths can literally fit in it, you need to account for the limitations in packing spheres together. In other words, there will be space between the Earths that will take away at bare minimum, 26% of the volume; so only 900 Earths or so could actually fit inside.
- banjokazooie, on 10/12/2007, -2/+7Don't assume that something automatically was created by a higher power just because it is amazing and blows your mind. God isn't a real entity, he is the common image that man created to represent the conscience. I know it seems mind blowing, but trust a little more in the real reason man was created: Chance.
- vaserv, on 10/12/2007, -0/+5I'm trying to the name but there is a theory that we could be the most advanced creatures in existance due to the fact that all races get to the point where they end up destorying themselves, not to far from where we have evolved to now..
- ingoldsby, on 10/12/2007, -0/+5Space boggles my mind. The distances and sizes are basically incomprehensible, especially when you start talking about relative distances between stars/galaxies etc.
- inactive, on 10/12/2007, -0/+5viclopez: the only thing that can "escape" from a black hole is Hawking radiation. Hawking radiation occurs when a pair of particles (particle and antiparticle) spontaneously appear next to a black hole. One of them passes through the event horizon and the other doesn't.
"In order to fill the energy 'hole' left by the pair's spontaneous creation, energy tunnels out of the black hole and across the event horizon. By this process the black hole loses mass, and to an outside observer it would appear that the black hole has just emitted a particle." -- Wikipedia - ChrisGranger, on 10/12/2007, -0/+4@burningmonk: Antares is larger than the Pistol star in diameter, just not mass.
Mindbogglingly, the largest known stars are well over two times the diameter of Betelgeuse, or 1500 times the Sun's diameter. Mind you, we're only scratching the surface in star measurement and talking about stars within the Milky Way. Who knows what may be elsewhere...

- DarkDays, on 10/12/2007, -0/+4wow, never seen the last two before.... Antares is gigantiously enormous...
- inactive, on 10/12/2007, -1/+5who said it was a mistake?
- elpayo, on 10/12/2007, -0/+4@fnaqzna - "[Antares] is so big that astronomers can easily detect and measure the size of its apparent disk, which gives an even bigger radius of 3.8 AU, three-fourths the size of the orbit of Jupiter."
linkage - http://www.astro.uiuc.edu/~kaler/sow/antares.html - cyrix, on 10/12/2007, -2/+6I still have a hard time mentally grasping how something as big as Antares just came together and stays together. I mean it's a giant ball of burning gas. That's it, nothing more. I understand the basic physics behind it, but when you really try to think about it, it just boggles your mind.
I would KILL to see a sun replicated in some new fangled high tech laboratory. Have them make a ball of gas and have it perform in a similar manner. I'm just at a loss for words right now I suppose, not in shock, but I just can't even begin to describe how my mind tries to understand how a giant ball of fire hovers in space without dissipating relatively quick despite gravitational forces. - D4r7h3v1l, on 10/12/2007, -0/+3You are thinking of the total perspective vortex.
- geoffmyers, on 10/12/2007, -0/+3Wow. Absolutely amazing! Excellent size comparison.
It's just too bad the image quality is so terrible... :-/ - WrecksTXP, on 10/12/2007, -1/+4Those plutonians feel so small now.
- cozinator, on 10/12/2007, -0/+3A mole is a unit, or have you heard,
Containing six times ten to the twenty-third,
That's a six with twenty-three zero's at the end,
Much too big a number to comprehend. - Floydian23, on 10/12/2007, -0/+3Stars only go supernova if they have enough mass to go supernova, which is at a mass of about 1.4 of our sun or greater. The more 'mass'ive a star the shorter the life span since more mass and in turn more gravity accelerates the star's life cycle.
So Antares, which is definitely at a cooler surface temperature than our sun due to it currently being a red giant (fusing helium into carbon, nitrogen, and oxygen at the core) rather than our sun (which is currently fusing hydrogen into helium). Antares has enough mass that it will last a short time and blow up in an extravagant supernova once the fusing process hits iron (and during supernova it will create a speckling of atoms with a nucleus larger than iron, such as gold or nickel, and all atoms with a nucleus larger than iron were fused in the midst of some ancient supernova), while our sun will go red giant, but won't have enough mass to continue on much further once it starts trying to fuse carbon, nitrogen, and oxygen.
The sun will die out and since it doesn't have the mass to go supernova, it will leave a churning, non-fusing item rotating in the sky, while Antares will leave in a beautiful supernova and because it's mass is so large, it will probably become a black hole afterwards. But others, like Betelguese, probably won't have the mass to become a black hole, and will instead turn into a neutron star following their supernova.
Yes, that iodine in your thyroid right now that helps your metabolism was fused in a supernova of the past. You are a product of stellar evolution!
There is no way around it. The big bang was an inflation of mainly hydrogen, with a little deuterium (heavy hydrogen or a hydrogen with a neutron) and helium (like less than 1%) and a touch of larger elements, and touch means like almost nothing.
Everything else was either fused in the core of stars or in the following supernovas. Don't worry though, there is still so much hydrogen available for future stars it cannot be conceived. The ratio is enormous, hydrogen versus all the rest of the atoms in the universe, I can't remember the expected value, but the number is mind boggling.
Hence the statement, we are all stardust, and it's not just some hippy talk. - TheBigBoss, on 10/12/2007, -3/+6I would hate to see what happen when Antares die out.
- burningmonk, on 10/12/2007, -1/+4You know, there are stars out there a few times the size of Antares, such as the Pistol Star and Eta Carinae.
- friend18, on 10/12/2007, -0/+3Makes me think of the Galaxy Song in Monty Pythons Meaning of Life. The Universe is amazing.
- camtech, on 10/12/2007, -0/+3We're gonna need it if suv's keep going the way they are.
- nuclearpenguins, on 10/12/2007, -0/+3Antares's diameter is 3.8 AU (93 million miles = 1 AU = The distance between the Earth and our Sun)
That's pretty damned big! - inactive, on 10/12/2007, -0/+3This remind anyone else of that thing from Hitchhikers Guide to the Galaxy?
Can't remember it's name, but it was a room containing a scale model of a universe, with a 'You are here' label
(or something to that effect) - camtech, on 10/12/2007, -1/+4one: it's called a dupe
two: who cares, if you take time to actually read some of the comments you'll notice a lot of people are seeing this for the first time. - Durinthal, on 10/12/2007, -0/+2Get to travelling at near-light speeds and we'll talk.
