At TFL, we're making journeys safer for everyone.

That's why we and London boroughs are lowering more speed limits to 20mph.

Because 20mph roads have already reduced collisions resulting in deaths or serious injuries by 24%.

However, for this conversation, we're going far away to other worlds, in fact, to other

What happens after the star that has given you warmth for billions of years dies?

What happens to the planet? I assume they would disappear. But,

J, a very good evening to you. Thank you for this. The planet's not only disappear,

it's possible that they have it a extended life. First of all, where is it that you were looking

to find WD1054, a stroke 226? Not a romantic name, but that is what I'm reading from the monthly

notices of the Royal Astronomical Society. Were you looking for this, J? Good evening to you.

Thank you very much. Not exactly. We were looking for evidence of planetary systems around

the White dwarf stars, which when I started my career, I think people thought was quite a

ridiculous idea. And I think that persists a little bit now. But I will say this, we were not
