NICOLAUS COPERNICUS
NICOLAUS COPERNICUS
Poland (1473 - 1543)
Nicolaus Copernicus was the first astronomer to formulate a scientifically based heliocentric cosmology that displaced the Earth from the center of the universe. His epochal book, De revolutionibus orbium coelestium (On the Revolutions of the Celestial Spheres), is often regarded as the starting point of modern astronomy and the defining epiphany that began the Scientific Revolution.

Richard Green

Dark energy and dark matter
Richard Green - Large Binocular Telescope (LBT)

The best interpretation of the suite of data that we have in hand right now is that the stuff of which this telescope is made, of which you and I are made, ordinary atoms that we learned about in high school chemistry class comprises about four percent of the total matter and energy density of the universe that we live in.

Eyes versus telescopes
Richard Green - Large Binocular Telescope (LBT)

Our eyeballs allow us to reconstruct the depth of the scene that we are seeing because they are spaced far enough apart that they give us a third dimensional view. Weíre not, these arenít nearly far enough apart to be interesting at the distance of astronomical objects.

The first time I looked through a telescope
Richard Green - Large Binocular Telescope (LBT)

But the thrill of the first time I went when I entered graduate school and got to ride in the cage at the focus underneath the five-meter at Palomar, which was the worldís largest telescope, and look in an eye-piece and see a galaxy that looked as beautiful as a photograph.

The Giant Magellan Telescope (GMT)
Richard Green - Large Binocular Telescope (LBT)

The GMT will be a telescope like this one but symmetric, filled in. So we have two eight meter dishes, these mirrors, and thereís about eight meters in between them.

How the Large Binocular Telescope (LBT) works
Richard Green - Large Binocular Telescope (LBT)

Thereís lots to do and this telescope will work frequently in a mode where you use the two sides in parallel with identical or similar instruments to get twice as much information on the same field of view.

Human curiosity and Galileo
Richard Green - Large Binocular Telescope (LBT)

Somehow as human beings we are innately curious. We really want to understand more and more about the world we live in and our place in the broader universe in which this planet, sun and solar system sits.

International partnership of the LBT
Richard Green - Large Binocular Telescope (LBT)

This is an extraordinary international partnership that has conceived and financed and made successful this telescope project.

Reflections on the International Year of Astronomy
Richard Green - Large Binocular Telescope (LBT)

I hope they realize that we are beings that were wired to live on a planet that has a dark night, and that if we donít protect that darkness and allow us, and children and grandchildren to at least experience it in special places, if not everywhere we live, then we will have lost a critical aspect of our being here.

Survey astronomy
Richard Green - Large Binocular Telescope (LBT)

So a very promising line of investigation, which is already going forward is looking at the sound waves that rattled through the universe in its earliest moments and then got frozen in the matter when the radiation was allowed to free-stream and the matter was interacting with itself.

Why the challenge of building the LBT?
Richard Green - Large Binocular Telescope (LBT)

It is all about the science. The astronomers are eager to find out about how planet systems were formed around stars. They want to probe into the hearts of galaxies and see the regions right around the black hole that's accreting material and ultimately shining away as a quasar.
