Johns Hopkins University (JHU) continues to pad its space community résumé with their interactive map, “The map of the observable Universe”, that takes viewers on a 13.7-billion-year-old tour of the cosmos from the present to the moments after the Big Bang. While JHU is responsible for creating the site, additional contributions were made by NASA, the European Space Agency, the National Science Foundation, and the Sloan Foundation.
Astronomers have developed a new technique to search for exoplanets – by looking for their crushed up bones in the atmospheres of white dwarfs. And it’s working.

A white dwarf was found that literally has to sides. One is Hydrogen. The other one is Helium. And it constantly rotates and changes those two sides. What's going on and how could this possibly happen? We're figuring it out with Dr Jeremy Heyl from the University of British Columbia. 🧐 More about the Two-Face star: 🦄 Support us on Patreon: 📚 Suggest books in the book club: 00:00 Intro 00:47 What?
