ESOcast 82: Zodiacal Light

The Atacama Desert in northern Chile is famed for its dark night skies, which can be enjoyed in their full glory thanks to the absence of light pollution. But even the darkest sky is not completely dark. Astronomers at ESO’s observatories often encounter a natural light phenomenon above ESO’s telescopes known as the zodiacal light.… Read More »

Stars in Alignment: UT Astronomy and the Discovery Channel Telescope

(Narrator) The University of Toledo Department of Physics and Astronomy, has signed on to partner in what leaders of the Lowell Observatory call their Boeing moment, that moment where they decided to bend their entire future on the construction of one of the world’s most sophisticated and powerful telescopes As the Boeing incorporation did when… Read More »

Have astronomers disproved the Big Bang?

If there’s a question that you guys never expected me to ever ask, it might be “have astronomers disproved the Big Bang?” And I understand why you might think that. After all, in my videos, I describe what scientists know about the most cutting-edge topics in physics research. So, perhaps I should be up front… Read More »

Astronomy & Telescopes : How to Use a Telescope With Setting Circles

So today we’re going to talk about setting circles on telescopes. So first off, to back up a little bit, every object in the sky has a coordinate associated with it. That coordinate is the right ascension and the declination, which is basically like a latitude and longitude on the sky. So, the steady circles… Read More »

Astronomy & Telescopes : How to Focus a Telescope

So let’s talk a little bit about focusing telescopes. Whenever you focus a telescope, basically the only thing you’re doing is changing the facing between the optical elements, whether that be a mirror or a lens or anything in between. As so there are a variety of ways that telescopes can be focused. So the… Read More »

History of Astronomy Part 3: Copernicus and Heliocentrism

Professor Dave again, let’s rethink the solar system. When we left off with Aristarchus, he had correctly proposed that the sun is the center of the solar system, rather than the earth. But he was way ahead of his time, and the geocentric model remained in place for centuries. This model was perfected by Ptolemy… Read More »

When art meets astronomy (UCL)

Most of my work involves nature, geology, technology and ideas of space and time and distance and collapsing distance. Most of my works have involved collaborating with people in different fields and disciplines. We’re all astronomers, so we look at things through a particular way, a particular methodology. Having Katie in the corridor has brought… Read More »
