I remember reading the quite good remark that "the only thing stars have in common is the name, stars...". I am happy with our own G-klass star isn't much bigger :D

I saw this while stumbling (http://www.stumbleupon.com/)and I knew that
Beteljuice was massive, apparently, if you were to place it on the same place as our sun, it would stretch out to the orbit of Mars. (Not sure if that is larger than
Arcturus or not as it isn't pictured.
I love this stuff :D
QuoteSpace is big. You just won't believe how vastly, hugely, mind- bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space.
That's perspective.
Yeah, Space is pretty big. It's only because these things are so far away that they look like dots in the sky. It makes you think, there must be some truely huge objects that are just far enough away that we just can't see them yet.
Imagine trying to explain to someone how big even Jupiter is before Kepler etc when people had little idea of scale in the solar system, I don't think they had numbers that big.
Ever been down the Mall in Washington DC? There's a scale map of the solar system running the entire length of Jefferson Drive.
Apparently, people now leave tributes at Pluto, between the Castle and Arts Museum, to mourn its passing as a planet.

You'll get over it.
I just hope I do :crazy:
Nice picture set. I've seen it before.
Actually there is another set which has also Death Star (yes, The Death Star), stars bigger than Antares, and Milky Way. Unfortunately it seems much rarer. I have the pics on my computer, but could not find where I had taken them. But I found 2 Youtube vids which have used the same pics.
In the 1st vid the star around which the Solar system planets revolve around (c 0:35->) must be an M class dwarf, because it is too small to be Sun (besides it looks red rather than yellow/orange.

The biggest known star VV Cephei (c. 1900x Sun diameter) or VY Canis Majoris (estimates 1800-2100x) would reach the orbit of Saturn. Imagine a sphere that big. At the other end, neutron star would be roughly size of a large city (but so dense you couldn't lift a spoonful of it)

That Universe scale is awesome - didnt have time to look at whole lot as work beckons me.
I'm still shaking after seeing the picture so I had to remove it! :D
that vid certainly adds to the awareness :O, i feel so small now :(

Our Uni has a poster on one of it's walls in a fairly random building. IIRC it's labelled 'Proxima Centauri'. Basically, some school in America wanted to make a scale model of our solar system. They placed the Sun towards the centre of their school. I believe it was several feet across (possibly a poster covering one entire wall, i've never seen it). Planets were distributed in buildings throughout the town the school was in. For our nearest start, a teacher and several of the students travelled all the way to the UK, so that they could put up a poster of our nearest star at the correctly scaled distance :)
Quite cool, I thought.

Very cool, or probably very hot actually.
Thanks for raising this Pen, I love this stuff :D
That is awesome.
Makes you wonder how big space is in totality and if you did know you probably couldn't even get your head round it.
All I know about space is that our galaxy itself contains 100 billion stars; it's 100,000 light-years side-to-side. It bulges in the middle, 16,000 light-years thick. But out by us it's just 3000 light-years wide. We're 30,000 light-years from galactic central point;we go round every 200 million years. And our galaxy is only one of millions of billions in this amazing and expanding universe!
Etc...

BlueBall was right!. It is stuff out there...and also blue!!! :D
In relation to each other, I don't suppose you have an illustration of that as well?

Dark energy?
Doing a particle physics and cosmology course taught me if you're not sure what it is and you can't see it call it dark. So because the gravity of a galaxy doesn't add up they say there is 75% Dark Matter. Dark energy comes about strangely too something about a density of -1. Anyway if it's not something you can see just guess it's one of these dark things.
...I should really pay more attention in uni.
