I have you loud and clear.

Hello.

Hello.

Welcome.

Science.

And that is the same physics, medicine, nature, or space, time, brain, life, the universe.

Hello, welcome to the naked scientist.

This is the show where we bring you the latest breakthroughs in science and technology with me Chris Smith and with Adam Murphy.

This week we are breaking codes and cooking up cyphers.

We're looking at the world of cryptography coming up

Cold War spy rings and can you make an unbreakable code. And in the news, see goals and superbugs and why it's harder to keep the

weight off as you get older. The Naked Scientists Podcast is powered by UKfast.co.uk.

Now arguably the really big news this week is the scientists in the UK have tracked

down what might be a habitable world orbiting a distant star. The planet is called K-2 18b, and Ingo Waldman told me what his teams discovered and how they did it.

We found a planet outside our own solar system which is rocky and it has an atmosphere which is potentially habitable.

That means it has the temperatures that may allow liquid water to exist on its surface and it has an atmosphere and that atmosphere has water vapor in it.

Sounds amazing.

Where would I need to look in the night sky to be able to see

where this is and how far away is it it's in the constellation of Leo and it's a

110 light years away from us so it's not the closest but it's also not the

furthest exoplanet we've ever discovered and how did you find it the Kepler

mission discovered this planet and the Kepler Space Telescope discovered the planet using the transit method and the transit method means that the planet orbits in our line of sight to the star. So it goes between us and the star. So that means that light of the star
