Our planet in perspective ...

[Physician]

I thought this series of photos really puts our planet in perspective ...........

I like it!

In science at school, a teacher was trying to explain how much empty space there is in an atom. He told us to imagine the diameter of the atom as the length of a football pitch. The nucleus would be made of protons and neutrons about the size of a tennis balls. Take Helium for example, IIRC there will be four tennis balls - two protons and two neutrons - sitting in a cluster. Place them on the centre spot as the representation of the nucleus. Helium has two electrons. Place a pea in each goal mouth and you have a representation of the size and distance of the electrons from the nucleus.

It's amazing that anything is solid when there is so much empty space in it! What a fascinating universe we live in!

[i3ooyah]

ah it would be cool to live on a planet the size of jupiter

[You See]

It's amazing how big Uranus is Physician!

A bit left field I know, but there are between 15 & 20 million miles of DNA in a human body !!

holy sh*t that does make you feel small

Another photo for some cosmic perspective:



The small white dot, about halfway down the rightmost vertical band, is the planet Earth as photographed from the Voyager 1 spacecraft in 1990, at a distance of about 3.7 billion miles. As explained on NASA's website, "From Voyager's great distance Earth is a mere point of light, less than the size of a picture element even in the narrow-angle camera. Earth was a crescent only 0.12 pixel in size. Coincidentally, Earth lies right in the center of one of the scattered light rays resulting from taking the image so close to the sun."

In 1994, during a lecture at Cornell University, Carl Sagan said of this photo, "We succeeded in taking that picture [from deep space], and, if you look at it, you see a dot. That's here. That's home. That's us. On it, everyone you ever heard of, every human being who ever lived, lived out their lives. The aggregate of all our joys and sufferings, thousands of confident religions, ideologies and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilizations, every king and peasant, every young couple in love, every hopeful child, every mother and father, every inventor and explorer, every teacher of morals, every corrupt politician, every superstar, every supreme leader, every saint and sinner in the history of our species, lived there on a mote of dust, suspended in a sunbeam."


Here's a close-up of that same image to show our planet in 'greater detail' (sic):

why cannot i post a photo that big i can only do 400x1024

[BraindG]

cos hes using [img ]

[jayjay99]

Ah ok, well in keeping with this thread, a couple of pics from Hubble,

A doomed star, Eta Carinae


And a black and white view on the universe

On this pic it really gets me thinking, each dot is an entire solar system!!! That's huge!!

I used to be really into Astronomy. Love seeing pictures of huge Nebulae - How I wish I could see something like that with my own eyes!

[SGHOM]

Love seeing pictures of huge Nebulae -

you & me both Kieran............

[jayjay99]

Yeah, me too, I bought a telescope last year with the hope of seeing all that kind of thing, but the way mt windows are I was having enough trouble though just seeing the moon. I'm gonna wait until I get a new place and then get a sky light fitted so I can have it setup perminantly, your meant to be able to see saturn and it's rings with it, that would be cool!
