Beeing an AWB-affiliate representing the
Linzer Astronomical Society - LAG / AUSTRIA I am happy to report the
following historic event at my hometown Linz in Upperaustria.
World premiere in Linz
Virtual walk through the ESO-Extremely Large Telescope at AEC Linz
24. Juni 2010

LAG Member Dietmar Hager (he is a well known international
"stargazer") used the original 3D CAD-Datafile of
European Southern Observatory (ESO)
on 24. Juni 2010 in Ars Electronica
Center(AEC) (Linz/AUSTRIA) to introduce the world biggest telescope planned
by ESO: The so called
European Extremely Large Telescope (E-ELT).
The numerous visitors had the unique opportunity to make a
virtual walk in Deep Space at AEC in 3-D Stereo through the construction, already before
the construction of
this telescope started in reality. The technical heart of Deep Space, the eight 1080p HD-
and Active Stereo-capable Barco Galaxy NH12 projectors, combined with the team
of AEC-programmers, have again proved their worldwide uniquiness.
Dietmar Hager presented, familiar with the complex technical equipment of AEC,
entertaining but equiping the visitors with knowledge. The visitors have been
situated sometimes inside the big telescope und the colossal dome and they
embarrassed, or better said hovered over the 42 meter primary mirror (consisting
of 1000 segments). The giant dimension of this biggest telescope, that mankind
is going to make, was a tight experience. From inside of the telescope we did a look to
the far Chilean desertmountains to the neighbourhood
of the VLT (Very
Large Telescope). Beside many technical details Dietmar Hager told about the
future importance of this telescope concerning our conception of the world.
The potential of this international telescope may influence - maybe change - our
worldview, like 400
years ago when Galileo looked through his first telescopes.
Additionally I am proud to tell
that here in my home town Linz the software for controlling the optics for this
telescope will be developed.
This 4 years lasting project will be coordinated by Professor
Ronny Ramlau at Institut Industrial Mathematics of the Johannes Kepler
University Linz. It's a cooperation of the Institute Industrial Mathematics, the
Johann Radon Institute for Computational and Applied Mathematics (RICAM) the
Austrian Academy of science (Linz) and the Industrial Mathematics
A great success for our astronomical historic city. The
important astronomer Johannes Kepler, who lived and worked in Linz from 1612 -
would have been very proud of this international success ;-)

Following some facts published by ESO:
ESO is currently designing the European Extremely Large
Telescope (E-ELT), which, at 42 metres in diameter, will be the world’s biggest
eye on the sky when it becomes operational in 2018. The E-ELT will tackle the
biggest scientific challenges of our time, and aim for a number of notable
firsts, including tracking down Earth-like planets around other stars in the
“habitable zones” where life could exist — one of the Holy Grails of modern
observational astronomy. A description of the exciting science this telescope
will allow is available in a new brochure ESO
has just released.
The mirror design itself is revolutionary and is based on a
novel five-mirror scheme that results in an exceptional image quality. The
primary mirror consists of almost 1000 segments, each 1.45 metres wide, but only
50 mm thick. The optical design calls for an immense secondary mirror 6 metres
in diameter, almost as large as the biggest primary telescope mirrors in
Adaptive mirrors are incorporated into the optics of the
telescope to compensate for the fuzziness in the stellar images introduced by
atmospheric turbulence. One of these mirrors is supported by more than 5000
actuators that can distort its shape a thousand times per second.
The telescope will have several science instruments. It will be
possible to switch from one instrument to another within minutes. The telescope
and dome will also be able to change positions on the sky and start a new
observation in a very short time.
