The European Extremely Large Telescope (E-ELT), a planned 39 meter telescope to be built high in the atacama desert has received sufficient funding to move into implementation. The observatory aims for first light around 2024.

http://www.eso.org/public/images/eso1440a/

At 39 meters the telescope will dwarf the current 8-10 meter class telescopes with 4 times the resolution and about 15 times the collecting area.

The telescope evolves around several science themes from large to small. It's extreme resolution combines will provide Hubble like views of galaxies 30 times further away but also with the power to resolve every pixel into a spectrum. This will mean a great deal for galaxy formation.

On the topic of exoplanets E-ELT will have a high precision spectrograph capable of confidently detecting earth like planets around sun like stars. With later instruments it will also be capable of directly imaging super-earths. With time it could provide evidence of continents and oceans.

It's high precision spectrograph of directly measuring the expansion of the universe for the first time. Redshift drift is an effect where the expansion of the universe causes redshifts to slowly increase over time.

E-ELT boasts big science and some incredible engineering.

We seriously need better names for this shit, it's getting embarrassing.

It's probably a result of many people in STEM these day being very specialized that don't allow for time to study culture and arts.

>need better names
A quick way would be:
  • Eye of Geography Name
  • Geography Name Telescope
  • Eye of Mythology Name
  • Mythology Name Telescope

What about historical figures in science and physics?

There's still no Carl Sagan telescope.

That brings up issues of nationality and starts a whole debate over who. You might say Sagan but I would say he had little to do with ground based telescopes, he also has a great amount of recongnition already. Someone like Jan Oort would be a good choice, his work was far more influential and yet few who haven't taken an astronomy degree know his name. He was also a founding father of ESO.

It also seems a bit self congratulatory to name telescopes after colleagues.

The Oort Telescope sounds like a great name.

And nationality doesn't matter, we need to get over that as a species, especially if we're going to be spacefaring.

And of course Sagan deserves something named after him, if you don't agree, you don't belong on /sagan/.

Unfortunately ideals don't pay the bills. A name isn't worth even the remote possibility of jeopardising funding.

>And of course Sagan deserves something named after him
The Mars pathfinder lander was named after him.

Science is done by scientists. They're not trying to sell people products, forming committees to come up with better names names for things don't get us any closer to mars.

Then what are we going to call a device that detects Oort-cloud objects?


HST image 7A24F will resolve a very large region of sky at a very high resolution. It'll be the largest compilation of images at this resolution anyone's done in awhile.
Other telescopes just look at the surface, the Hubble looks deeper. We'll call it "Deep Field"

This one can see even further.
..."Ultra Deep field"?

>Enhance
This one can nearly see back the the start of the universe.
Fuck it, Call it "Deep Field Extreme. But capitalize the X.

for a moment I thought it was called Worlds Largest Optical Telescope
this is indeed getting retarded, whats wrong with John or Bill?

Nice post, tiny nitpic. The deep fields are actually a very small region of the sky.

Does it get red, blue, infrared and ultraviolet light too?

Yes. Initially the instumentation will focus on the near infrared because adaptive optics is easier there and so you get the most out of the telescope. Possibly with a mid infrared camera also. After that visible and UV will come in.
