Last January, the National Science Foundation, the Thirty Meter Telescope, and DISCOVER cosponsored a panel discussion at CalTech between DISCOVER/Bad Astronomy blogger Phil Plait and four of the...

The Thirty Meter Telescope (TMT) has marked "a major milestone on its way to becoming the world's most advanced and capable optical telescope," according to the TMT project team.

The Thirty Meter Telescope will be manufactured piece by piece in the Vancouver area and then assembled on Cerro Armazones in Chile or Mauna Kea in Hawaii.

The big bang, black holes, dark matter, dark energy, extrasolar planets, brown dwarfs, quasars, pulsars, cosmic rays, the space-time continuum, galaxies and more galaxies. Do you see what Galileo...

A next-generation astronomical facility will incorporate a segmented mirror and cameras designed to study dark energy, search for extrasolar planets, and examine the origin and evolution of the...

A proposed telescope reignites discussion of the future of astronomy on the piko of Hawai鈥榠 Island.

Telescope discussion has economy, technology at odds.

Mauna Kea has some of the best atmospheric conditions in the world to build a proposed Thirty Meter Telescope, but a desert mountain in Chile is also in competition for the $1 billion facility,...
