The South Africa Space Special
|
This week on the Naked Scientists we cross hemispheres to explore galaxies far far away. Chris presents live from Johannesburg to discuss the South African Large Telescope whilst back in the studio we explore the effects of space travel on the body, the expansion of our universe and the possibilities of another planet earth. We also investigate effects on our hearing and bring you a special kitchen science that could be out of this world.

Now in the news last week was the story around what, essentially, is a very boring star. Now the star is called 55-Cancri; it's 41 light years away; found in the constellation Cancer; and it seems to be very similar to our Sun.

We talk to Kevin Fong who is a space physiologist about the problems associated with actually living in space.
Is the artificial gravity you see on Star Trek possible?' Do you think we could have some kind of artificial gravity system that would get over these effects?
Is radiation nearly as much of a problem outside the orbit of
say, Mars as it is closer to the Earth? I'm wondering if deep space
vehicles have more or less need for protection from radiation than those
that are exploring nearer to the Sun.
Brian won a share of the five hundred thousand dollar prize for his discovery that the universe is expanding as it ages and the older it gets, the faster it expands.
I’ve heard that tools like hammers that make short, loud noises are supposed to be more damaging to hearing than something that makes a more continuous noise. I’d just like to get some confirmation on that.
Colin sent us a rock he thought was a meteorite, we visit the natural history museum to find out if he is right.
Can we see black holes from the Earth?
