Episode 280 - Nanodiamonds, Stardust, Comets and erasing Stars

Listen Later

Astronomy can be quite beautiful at times. From nano-diamonds giving the galaxy a shimmering glow, to stardust leftover from the creation of the solar system hitching a ride on a coment. We also find out about new ways to hunt for exoplanets by erasing stars with filters.
