What percentage of stars live in binary systems? Are there Lagrange points all the way down? Can there be a rogue gravitational wave? Why do stars twinkle? Answering all these questions and more in this week's Q&A show.

Mars is full of toxic perchlorates that can be very harmful for future human missions. So, when people go to Mars, they will need to fix it. NASA has awarded a NIAC grant for a project that can help solving this problem. It's called Detoxifying Mars: the biocatalytic elimination of omnipresent perchlorates.👉 More about the NIAC project:https://www.nasa.gov/general/detoxifying-mars/🟣 Guests: Dr. Lynn Rothschild, Dr. Garrett Roberts Kingman🦄 Support us on Patreon: https://patreon.com/universetoday📚 Suggest books in the book club:https://www.goodreads.com/group/show/1198440-universe-today-book-club00:00 Intro02:31 Perchlorates on Mars10:48 The NIAC proposal35:09 What's next49:18 Current obsessions53:35 Final thoughts📺 VIDEO VERSIONhttps://youtu.be/GitfDWpm6UU📰 EMAIL NEWSLETTERRead by 60,000 people every Friday.
