Bigger, tagged Version

So, Deneb's fogs should be Reddish...

What's in a Name: Arabic for "tail" because it is located in the tail of the Cygnus, the Swan.
Claim to Fame: 19th brightest star in the sky (apparent visual magnitude = 1.3)
Type of Star: White Supergiant (A2 1a Spectral Class)
How Far Away: 1800 light years away
How Big: 60 times the sun's diameter, 30 times the sun's mass
How Bright: 60,000 times the sun's visible luminosity (Mv =-7.2)
Where to View: Located in Cygnus the Swan, also called the Northern Cross (Star Map).
When to View: June through November from northern middle latitudes.
Oct 21, 2010 look... no hands link
you mean you just learned there actually is a star called deneb?
Oct 21, 2010 Alloh link
No, i mean that this is a cool picture that I met today... which I'd like to share with my friends who combat in Deneb!

you met this picture? what is it like?

Smarter, more coherent, and a lot more articulate than Alloh.

it is a pretty picture though

Awesome photo.

Is this true-color?
Oct 22, 2010 Alloh link
yes, "natural" colors.

No, NOT natural colors at all Alloh.

Simply BS, ALL the pretty pictures of space are NOT true color.

Sorry.

This image specifically is showing mostly IR frequency radiation blue shifted (up) to be visible as red. That is not at all what that nebula (or any, nebulas mostly emit energy at IR spectrum and lower) would look like with the "naked" eye (were it possible to view such a thing naked). Most are showing IR and UV light (Sometimes radio frequency and even lower and higher frequencies) as if they were a visible frequency, and colors are simply adjusted to make 'em look cool... they are also adjusted for red/blue shift. In the "official" "scientific" images released by astronomers that is.

Notice the "Assembled in Photoshop" in the tag.

Most hydrogen emission nebulae glow red, just like that actually. It's visible red light, but it's too dim for the human eye's cone cells to detect. The part we see when looking through a telescope is the blue/green emission lines since the rod cells in our eyes can detect that.

If it was bright enough, it would look red like that through a telescope.

Well, given that our ships probably have light-amplification visualization thingamajigs, we could see red nebulae.

If we stayed in sector long enough. Or is it better when up-close? But, what are the dimensions of the Deneb nebula? The density? Would it even matter, compared to the Deneb fog in-game, which is a largely local phenomenon (is it not)?

Questions upon questions. But it's a pretty picture.

It's a matter of perspective.
That's the gas clouds in the milky way behind Deneb. Heck, the entire scope of our "massive" war takes place within the blue glow around the star in that pic. There might very well be asteroid belts and ice rings we can't see. :)

Nevermind that the size of the star in the system map is rather small, about the same as the one at Sol II which is supposed to be comparable to Sol... It's called 'science -fiction-' ;)

To be fair, wormholes mean nothing in the way of spatial relation. The systems could be trillions of light-years away from each other.
Oct 27, 2010 yodaofborg link
It's not about distance tosh, he was referring to the fact that in VO, Sol II is supposed to be a similar sized sun to Sol, and that the Deneb sun (on the map) is similar in size.

Which is of course wrong :) IE it's Sci-Fi, who gives a hoot?
Oct 27, 2010 Pizzasgood link
Hmm, but then, who says that sectors are all the same size? Maybe the ratio between Deneb and Sol II sector size is the same as the ratio between the stars Deneb and Sol II.

Pizzasgood, making excuses since 1991-ish. (I don't remember precisely when, considering I would have been a toddler at the time.)

Ok, I misunderstood, because I thought 'system map' meant the overview and 'sector map' the actual view of the system. My bad.

And there is no radio between Deneb and Sol II. They have a phone line laid between the systems. >_>
Oct 29, 2010 Pizzasgood link
Heh, typo. Ratio, not radio. I'll go back and correct that.
Oct 31, 2010 TehRunner link
sure makes our war look...meaningless. Soo much pretty space and we quarrel over such a tiny portion of it. -Sigh-
Oct 31, 2010 Alloh link
Should we ask the devs to make Deneb much bigger, and reddish/blue fog?

@soham: Almost "natural" colors, enhanced by combined 60H of exposure. No infrared/UV/Radio. No exactly as when you look up, but simply "magnified".
