How do asteroids get their names? You have to discover an asteroid to name it, but you still can't name it after yourself or your cat. You also can't buy the naming right, though someone might give theirs to you.

Constellations, asterisms, galaxies and star clusters are all groups of stars. So how are they different? Why isn’t the Big Dipper a constellation? Where are the globular clusters? And if Saturn is in Virgo, has it left the Solar System?

An enormous dragon circles the northern celestial pole. The constellation Draco contains a star that was the pole star at the time of the pharaohs, some interesting galaxies and the most complex planetary nebula yet discovered.

Will a secret organization and an evil genius succeed in destroying a big physics experiment and killing the scientists involved? Can George and Annie find and disarm the quantum bomb? How is Schrödinger's cat involved? Another great blend of fantasy and science from Lucy and Stephen Hawking.

Why did the British government in 1820 want to build an astronomical observatory eight thousand miles from home? Which astronomers are buried on the premises and which one went home after a year in the "dismal swamp"? Here are some of the stories of the Royal Observatory at the Cape of Good Hope.

We no longer see the heavens as perfect and the stars as eternal and unchanging. Even the Universe had a beginning, and everything that we observe changes and evolves. Many of these changes involve cosmic collisions.

We live in the Milky Way galaxy. When we look up at the sky all the stars we see are part of the Milky Way. But did you know that most of the Galaxy is made of mysterious, invisible dark matter and that there’s an even darker secret at its heart?

How did our universe come to be? The Big Bang theory is the explanation that most scientists currently accept. Let's look at what we mean by a theory, what the Big Bang story is and why it's not as crazy as sounds.

The Pleiades - the Seven Sisters - were shown in star catalogs six thousand years ago. Visible from northern and southern hemispheres, probably every culture that ever watched the sky had a name for them. But what is this group of stars? And are there actually seven of them?

Try to imagine seeing the northern lights dancing across the sky above you. A film on a flat screen couldn't duplicate this. But what about one made to be projected on the dome of a digital theater? This was the aim of "Experience the Aurora."
