    .....................of the day. Well I think it was anyway Tongue

    ‘Pillars of Creation’ Photo Was Captured When Pillars Were Already Long Gone

    pillarsofcreation-mini.jpg

    Captured on April 1, 1995 by the Hubble Telescope, the photograph Pillars of Creation is one of the most famous space images ever made. Here’s a crazy fact though: did you know that the “pillars” seen in the photo were already long gone by the time the image was captured? Astronomers have concluded that the pillars — which measure up to 4 light years in length — were destroyed about 6,000 years ago by the shock wave from a supernova. Because of how long it takes light to travel across such vast distances, we can currently see the shock waves approaching the pillars but won’t actually see their destruction for another thousand years or so!

    It's fascinating really as we all tend to think what we see is instant and in reality nothing is.

    You look at the moon and you see what it was like a second or so earlier. Light from the sun takes about 8 minutes to reach Earth.

    I'm looking at my computer screen and my brain thinks it's in real time and for all intents and purposes it is as the light from it is travelling at about 186,000 miles per second but there is in fact a minute fraction of a second before it reaches my eyes.

    Light from the nearest star to us takes about 5 years to reach us.

    Even light from Mars takes about 20 minutes.

    Nonsense!

    Light is instantaneous, but TIME travels at 186,000 miles/second faster than light.

    It's all relative GrinGrinGrinGrinGrinGrin

    Can't they just use a faster shutter speed.
    An extra stop will half it to 500 years.
    Upping the iso should knock another few hundred years off.
    Bloody hell why didn't they put me in charge Tongue

    The reason for the inverted black 'L' shape at the top right is that image data are recorded there apparently - things like the celestial coordinates of the frame centre, start & finish of the exposure, orientation of the spacecraft, image number - omitting whether or not the flash fired! Wink

    It's where they've blanked out the alien space craft they didn't want us to see.

    Or that's what the conspiracy theorists would say. Grin

    Now you've started something!

    Right then, I'll finish...... When you consider the millions of stars in our galaxy(apart from me, that is)and the millions and billions of stars throughout the universe, we are not just on planet earth to live and take photographs. There must be other things waiting for us in the dark blue yonder. I hope I end up on planet EPZ with all you happy lot.Grin Just had a thought though, it would be like Groundhog Day.Wink
