Way more galaxies!
Hear Erin and Jacqueline talk how many galaxies there are in the Universe. We’ve known that it’s a lot – thanks Hubble! And, now we know that’s even more than previously realized.
PNM + Radio Astronomy = Awesome Pledge Drive
On tonight’s pledge drive edition of the Perpetual Notion Machine, we’re pleased to have Jacqueline Goldstein, one of the producers of WORT’s Radio Astronomy, as our guest. She’s a third year grad student in astronomy at UW-Madison, but strongly believes in reaching out to the public to present the latest news and research in astronomy. […]
Mapping Dark Matter with Hypervelocity Stars
Hypervelocity stars race across the Milky Way at speeds greater than 1,000,000 miles per hour! Listen to learn how astronomers hope to use these speedy stars to measure the distribution of dark matter in the Milky Way!
Corpse Star Death Ray
AR Scorpii is a binary star system unlike any we’ve ever seen before! Listen to learn how astronomers discovered this bizarre system with a red dwarf star that is constantly under fire from the corpse of its binary companion.
