astro picture for the day


Nasa Hubble Space Telescope image

This picture combines data over a ten year period; telescopes before the Hubble space telescope could view the universe back to seven billion light years; the Hubble calculated the Big Bang to 13.7billion years old precisely, and has imaged it here to 13.2 billion light years distant.

    and a black hole laser,

    These black holes simulate certain features of black holes; just not the gravitational attraction of an actual piece of mass crushed to densities which would create an actual black hole. Still, this metamaterial idea is . . . fascinating!

    The Dna-nanotechnology article which is first is proof in my opinion that we are in a nanomanufacturing era; sure, it's not one that's going to turn the world upside down and allow just about everyone to live for free and perfect health for as long as they please; but, it's capable of making things and progressing to a much more capable nanomanufacturing system.
