Earth on the scale of things...

No it isn't

At nighttime then xD

I think Carl Sagan expressed our situation very well

(Yes, this isn't the first time I've posted this)

Thats quite thought provoking

Better

Douglas Adams didn't do a bad job either:

"Far out in the uncharted backwaters of the unfashionable end of the Western Spiral arm of the Galaxy lies a small unregarded yellow sun"

Now I may be being stupid here but can we see antares and is it the north star?

We can see it, but it isn't the north star- that's Polaris, in Ursa Minor.

Scorpio is very low in the sky in July as viewed from the UK, to the south.

It's quite a humbling thought to realise that on a universal scale a human life is over so quickly as to be almost non-existant and our whole world is nothing more than a tiny ball of matter floating in an unconcievably vast universe.

lol, that was one of those questions in my mind that hurts your head too much if you try and think about it, the same sort of thing as trying to think what it was like before you're born and when you're dead, just if it'd be blackness or something else.

Glad you all liked them

Rense's still going?!

Crikey...I thought that such booker-nominated articles as "Connecting The Dots - Zionists & 911", " Battle Of LA UFO: Stunning New Photo Enhancements" and "Makow - Bill Gates: Satanist In Sheep's Clothes?" would have sank the site by now.

How about a photo of a planet orbiting another star?

They've kinda ruined it with that big light on the corner.

Yup Hence why we don't have the telescope there anymore.

Sirrus looks like a hot one
Do thye know what its made out of/burning?

 

[Sirrel Squirrel]

please stop

Sorry, I feel strange tonight

Hydrogen, like any other main sequence star. Some helium and a few heavier fused elements.

It's not particularly hot, actually. Twice the surface temperature of the sun, at a push. Rigel is hotter (blue stars have the greatest temperature).

What is Antares?

Here is a bit of info about Antares for you....

Description of the Star
Antares A is the cool red M1.5Iab-Ib supergiant primary of a double star system. The effective temperature is about 3100 K. The star is approximately 10,000 times as luminous as the sun. Acccording to Burnham Antares A would have a mass of 10 to 15 times that of the sun.

This huge star has a radius that is probably almost 4 AU. If the sun were replaced by Antares A at the center of the solar system, the earth would be engulfed, as would be Mars and the Asteroid Belt. Jupiter would orbit about 1 AU* from the surface of the star!.

* 1 AU = The Astronomical Unit
The Distance from Earth to Sun

The astronomical unit, the AU, is a unit of distance equal approximately to the average distance between the earth and sun. More precisely stated, one astronomical unit is approximately the value of the semimajor axis of the orbit of the earth. (For the purists, the AU is actually a tiny bit less than the semimajor axis.) This represents a distance of about 93 million miles or 150 million kilometers.

Expressing a distance in AU then represents a comparison with the earth's distance from the sun. Jupiter at 5.2 AU from the sun is 5.2 times further from the sun than the earth. Pluto at 39.5 AU is almost 40 times farther from the sun than the earth is.

I thought the hotest hot rating went

White, Blue, Red, Orange, Yellow

I thought the hotest hot rating went

White, Blue, Red, Orange, Yellow

The hotter a body, the shorter the wavelength at which it will emit most of it's radiation (Wien's displacement law). Blue stars output massive amounts of ultraviolet.

It's Blue, White, Yellow, Orange, Red isn't it?

I think i messed up red, orange and yellow but i thought White hot was the hottest you could get
