giant telescope?

Post Reply New Topic

The Large Binocular Telescope currently operates at around three times the resolution of Hubble and should eventually operate at about ten times the resolution thanks to it's adaptive optics. (side by side piccy in the link)

There are a number of giant telescopes in the works at the moment, the largest is E-ELT a European project to build a 40m segmented telescope next year. They scrapped the plans for a hundred metre telescope called OWL in favour of being a bit more conservative with budgets.

Given the current interest in exo planets you can pretty much guarantee that the OWL telescope will be built eventually if E-ELT is successful because an telescope with a diameter of at least 80m is required in order to study the atmosphere of earth size planets around nearby stars.

Sorry, links removed because I'm too new to be trusted with them...

I love the astronomical acronyms!
VLT = Very Large Telescope.
E-ELT = European Extremely Large Telescope
OWL = Obscenely large Telescope
and
LBT = Large Binocular Telescope (the one you are talking about
in this, there will be PEPSI, the Potsdam Echelle Polarimetric and Spectroscopic Instrument.

It is pretty amazing what modern telescopes are capable of.
One space telescope I am looking forward to is GAIA, the Global Astrometric Interferometer for Astrophysics, which will measure the positions of billions of stars, measure the distance of over a billion stars, and measure the proper motion (the movement relative to our solar system) of lots of stars.
Oh, and it will have nearly 1 GIGAPIXEL of CCDs!
