    Earth Images

    NASA's Cassini spacecraft captured earth ( blue dot ) and moon images from nearly 1,5 billion kilometers away somewhere in the Saturn system. The black and white image is from the 'messenger' probe and some 98 million kilometer away from earth. Stunning.

    Another reminder of our insignificance in the expanse of the universe...

    I always find that comforting, no matter what is stressing you out, it's absolutely nothing in the grand scheme of things.

    Well said and the distance of 1,5 billion kilometers is not even close to 1 lightyear. What is 1 lightyear in the observable universe anyway, a dot
    perhaps, where the edge of the universe would be somewhere 93 Billionen lightyears out. Space probe voyager1 has max speed of ca 62000km/h and it would take 17500 years to reach just 1 Lightyears :-( Its getting late here, hope I got all the numbers right :-)

    Alright guys; after the ' astrology thread ' became bit stretched, think it's about time coming back to the real thing:-) and having a short but exciting plunge into our universe :-) with return ticket of course :-) and to cut some corners, our starting point well be far beyond our Milky Way

    And now below that's the complete observable universe and even our mighty Milky Way is not even worth a dot,unless one of you can point it out dead straight ;-) ;-)

    Our Milky Way and where we're

    Well not quite.

    If we were there, we'd be about 15 million light years away from the Milky Way as this is actually M83 in Hydra (the Southern Pinwheel)

    As you know, we can't see our own galaxy like this, but yes, it would look something like M83. You could see M83 with binocs if it wasn’t for all the bloody neighbours’ lights.
