      I am no arbiter of humour, but I think this April Fool prank is fairly lame (unless there is truth in the unlikely twitter rumour that the NYT was pranked)

    Create and destroy on a scale you've never imagined with the ultimate space simulator. Harness the power to create black holes, collide galaxies, and manipulate gravity with just a few clicks. Inspired by the software astronomers use to unlock the mysteries of our universe, never before has astronomy been so interactive or so much fun.

  • TMT will also cost between 1 and 2 billion dollars when all is said and done. This is not quite at the scale of the world’s biggest science projects, like the Large Hadron Collider or the James Webb Space Telescope, but it’s getting there. In fact, TMT and other proposed observatories of this generation may end up being the biggest telescopes on Earth for all time because the funding required to go even larger would more logically be directed towards putting telescopes in orbit.
  • Adaptive optics is a big part of TMT’s design. It will work both on Mauna Kea and Armazones, but astronomers expect it will work better on Mauna Kea. This is because the upper atmosphere—the part above the boundary layer—is somewhat less turbulent above Mauna Kea than it is above Armazones. Why? According to Racine it’s partly a function of latitude. Because Mauna Kea is nearer the equator it’s relatively unaffected by the jet streams that flow at higher latitutdes both north and south. Armazones’ upper atmosphere is a bit more turbulent in comparison and so somewhat harder for adaptive optics to deal with.

Apophis Asteroid could hit the Earth in 2068, warns Russian Scientists - 0 views

  •  
    A large asteroid will impact our planet in 2068, according to research conducted at the State University of St. Petersburg, Russia. It is a rocky body of 370 meters in diameter, discovered more than a decade ago and baptized Apophis 99942.
