Ep. 580: Exploding Dwarfs

You’d think that a white dwarf star is the end of a stellar life. It’s all downhill from there. A long, slow cool down towards the end of everything.

At some point in the next few billion years or so, our Sun is going to start heating up, using up all the fuel in its core, and then eventually die, becoming a white dwarf. It will then slowly cool down to the background temperature of the universe, becoming a black dwarf.

Ep. 577: Mars in Opposition

Every two years or so, Mars lines up nicely with the Earth. It only takes two minutes to communicate with rovers, you can see the polar ice caps in a small telescope, and it’s the best time to send spacecraft to the red planet.
