Cosmic Vertigo - Abc Rn

Six hours of patience and preparation, and Buzz Aldrin and Neil Armstrong are ready to open the hatch.

After their dramatic landing, the astronauts' scheduled rest was never going to happen.

This is it. Buzz Aldrin and Neil Armstrong begin their descent to the lunar surface. But all does not go to plan...

As the Apollo 11 crew finalise their lunar orbit, they drift around to the far side of the moon - and out of radio contact...

So far on their journey to the moon, the Apollo 11 astronauts haven't been inside the Lunar Module - that's about to change...

As they continued their trip to the moon, the Apollo 11 astronauts had to figure out how to live in space

Exactly 50 years ago, the three Apollo 11 astronauts were on their way to the moon - and they shared their view with those watching closely back on Earth.

50 years after the Apollo 11 mission successfully landed humans on the moon, hear about the journey's crucial moments - and the near misses.

We join two observers for a total eclipse of the sun.

The International Space Station is travelling in low Earth orbit at a leisurely 7.66km per second (approx). Moving at that speed, the crew of the ISS witnesses a sunrise and sunset every 90 minutes.

The search for alien life continues but at what point do we declare that we are alone in the Universe?

You'd think we'd notice thousands of explosions in the night sky. Shorter than a millisecond, these bursts were first recorded in 2007 and while scientists know they're there, we are still unsure of their origin.

If you wait long enough, would another Universe spontaneously arise in front of you? Chances are it won’t happen in your lifetime… But it could.

Temperature levels across the Universe vary wildly. The Boomerang Nebula is the coldest known object, but back on Earth scientists are working towards achieving absolute zero. It doesn't get any cooler than that.

The hottest thing in the Universe isn't the core of a planet, or the centre of an exploding star. It's created here on Earth by scientists working at the Large Hadron Collider.

Could there be a time when we look up at the night sky and see more objects, planets and stars, than dark space? Join Alan and Amanda as they tackle another of your Cosmic Queries.

Stargazing Live on ABC TV gathered astronomers and astrophysicists for three nights of discoveries and record-breaking observation. Join Alan as he explores the Siding Spring Observatory, where Amanda worked, and asks these professional stargazers (plus one red-haired comedian) what makes them feel Cosmic Vertigo. Featuring Karlie Noon, Fred Watson, Becky Smethurst, Greg Quicke, Andrea Boyd, Amalia Sicardi, Tim Minchin and Kumi Taguchi.

We’re told space is a vast empty vacuum. But how empty can it be, if we know it’s full of stars and black holes, nebulas and galaxies? Alan and Amanda hop aboard a space elevator and rise through the Earth's atmospheric layers to explore our not-so-empty Universe.

Imagine the mass of the sun crushed into something the size of the earth – what you're picturing is a white dwarf. But things can get much more dense than that. Amanda and Alan deliver a lesson in density with a side of salt and aioli (BYO chips).
