From November 19, 2020. Today’s top story focuses on the Blue Ring Nebula, which researchers say is the phase of a star merger never seen before, providing the missing link for merger progression. Plus, stories on Mars, laboratory supernovae, Steve (no, really), JUICE, gravity waves and Enceladus.   We've added a new way to donate to 365 Days of Astronomy to editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!
