Listening to Light (04-11-2012)
When we look up on a dark night, we see a sky filled with stars. The light from a star, like the light from a flashlight or a lightning bug, is one form of electromagnetic radiation.

A Tour of 3C 186: An Interview with Dr. Aneta Siemiginowska (03-23-2012)
A galaxy cluster containing a structure never previously seen so far from Earth has been observed by Chandra X-ray Observatory.

Ice Core Records: From Volcanoes to Supernovas (01-27-2012)
Researchers have been traveling for decades to some of the coldest places on the planet to uncover some of the secrets from space that have been left behind on Earth.

Aesthetics and Astronomy (12-10-2010)
Every year, hundreds of astronomical images are released to the general public by the many telescopes on the ground and in space.

A Tour of GOODS (10-14-2010)
The most powerful telescopes on the ground and in space have joined forces over the last decade in a unique observing campaign, known as GOODS, which reaches across the spectrum and deep back into cosmic time.

A GPS System for Cosmic Images (08-16-2010)
The Chandra X-ray Observatory captures information about the high-energy Universe. Chandra data is inherently digital. As the methods to communicate digitally have advanced, so too have the efforts to keep Chandra engaged with the public.

Peering Into the X-ray Future (05-05-2009)
This episode will touch on some of the areas in which astronomers hope X-ray telescopes will push our knowledge forward in the years to come.

Just Two Numbers Is All You Need (06-02-2008)
Black holes sound wildly complicated. After all, there are all sorts of bizarre things going on: intense gravity, the warping of the fabric of space, the distortion of time itself. But when it comes to describing black holes, it comes down to just two numbers: the mass of the black hole and its spin.

Exploring The Large Magellanic Cloud (04-02-2008)
The Large Magellanic Cloud, known as the LMC, is a nearby satellite galaxy of our own Milky Way. At a distance of around 160,000 light-years, the LMC is the third closest galaxy to us. But the LMC is more than just a nice little sidekick.

The Universe Darkly (02-29-2008)
When you look up at the night sky, you see a lot of things glowing like stars, planets, and galaxies. So it might sound strange to hear that most of the Universe is actually dark. The truth is the protons, neutrons and electrons that make up everything we can see, and that means everything with telescopes we've got, accounts for only about 4% of the mass and energy of the Universe. The rest is dark and mysterious. More specifically, about 70% of the Universe is what is known as dark energy; about 26% is so-called dark matter. Modern day astronomers have developed many tactics to explore the dark Universe, including using telescopes like Chandra.
