NASA's "Blue Marble" images

This spectacular “blue marble” image is the most detailed true-color image of the entire Earth to date.

Wow.

I don’t like it (even though I live in it). (:TNG)

I do like the pictures though. mmm…all that ice cream topping…

Wow, it’s actually looking good!
And Soya, I’m sad to disappoint you, but it’s snow and ice, and not ice cream :frowning:

My jokes aren’t working :frowning:

Soya:
To much Naruto, makes YOU Naruto!

Thanks wisanggeni good addition… I’ve seen them before myself. I was stunned when I first realised just how big Antares & Betelgeuse were. And that Sagan lecture with the furthest away known image of the earth is great. Even microscopic is an insufficient description.

I’m glad we share the same “joy”, Kail.
Those pictures, really stimulates both nerves and emotions.

…if only ‘Dubia’ share the same knowledge…

Antares scares me. It makes the sun look like a flea. I don’t think there’s anything within 3 billion light years from that that can survive (except maybe the Black Hole).

Be joyous that Sol isn’t as big as Antares… those big stars only last a fraction of time that a star the size of Sol lasts. They have a rather sudden and abrupt end with some nasty left overs as well. But the distance from Sol to Antares… is some 600+ light-years, so we might have a problem on the 3 billion trouble. Mind you its a binary system, so the end should be fairly interesting. Interesting thing about Antares is that despite having a diameter of 796 x Sol, its mass is 12 x Sol.

The only Duiba’s I know of are not saying much that’s for sure.

3 billion light years sounds too much? :stuck_out_tongue:
The speed of light in vacuum is 299,792,458 meters per second, which gives us 1,079,252,848.8 km/h (Speed of light - Wikipedia). That means light moves 1 billion km/h!

A year is 365.24 days, and a day is 23 hours, 56 minutes and 4,09054 seconds, which gives 8,6164.09054 seconds a day. Now let’s see if Microsoft’s calculator is good enough for this…
86,164.09054x365.24 means we got 31,470,572.4288296 seconds in a year!
And finally I can tell you that the light travels 9,434,640,263,105,855.8471568 meters each year(in vacuum)! That’s about 9,5 quadrillions(9.5x10x10x10x10x10x10x10x10x10x10x10x10x10x10x10x10x meters)!
To that, we can add that the main disk of the Milky Way Galaxy is about 80,000 to 100,000 light-years in diameter, about 250,000 to 300,000 light-years in circumference, and outside the Galactic core, about 2,300–2,600 light-years in thickness.

Now that’s all from me, thanks for your time (:SHY)

P.S This is not spam, it’s science ;D

How does one discern the difference ???

There’s no way to see the difference between science and spam, at least if we’re talking about numbers. But if you’re interested to investigate this, feel free to do a calculation yourself ;D

Kind of “related” to the topic. So…
