On Friday the European Southern Observatory broke ground in Chile on the construction of the European Extemely Large Telescope (E-ELT), which when finished in 2024 will be the largest ground-based telescope in the world.

The mirror will be 39 meters across.

Meanwhile, construction of the Thirty Meter Telescope remains stalled. It was originally supposed to be operating before E-ELT, but that is becoming increasingly doubtful. Its builders can’t get Hawaii to approve a building permit, and they haven’t yet been willing to admit that they will never get permission to build there.

    Bob, I’m very interested in the TMT and I’m grateful to you for keeping us up to date on developments as they come up. When is the next decision date?

  • Nick P asked, “When is the next decision date?”

    No date has been set for any next step. All remains in limbo. The consortium building TMT has said that they need a decision soon or they will leave Hawaii. I expect them to leave.

    What a crime. The best spot in the world taken over by pagans and the politicians cowering at their every demand.
