Differences Fall Away Like Sand on Titan
Using spherical grains called ooids, found on Earth in shallow, tropical waters, scientists have found a possible mechanism for the formation of hydrocarbon sand on Titan. Plus, rocket launches, Jupiter and Mars, space explosions, and this week in rocket history, we look back at Britain’s Ariel satellite program.

Cool worlds, exploding stars, and an asteroid that missed Earth
Join us today as we look at how citizen science helped discover 100 cool worlds nearby. Then we examine evidence that exploding stars may have contributed to a mass extinction on Earth. Speaking of mass extinctions, an asteroid narrowly missed our planet last weekend. Because 2020.

Whole lotta what: Gamma-ray heartbeat heard; Stars with planets have no chemical fingerprint; ‘Oumuamua not made of molecular hydrogen ice
Join us today for a lot of unsatisfying news. First, two objects appear to be pulsing in gamma-rays at the same pace, but they’re 100 light years apart. Next, it turns out that stars with planets look chemically like any other star. And finally, our interstellar visitor, ‘Oumuamua, is NOT made of molecular hydrogen ice.
Betelgeuse dimming again! Hubble understands last winter’s dimming. Plus Ganymede hit with massive asteroid in distant past.
Join us today as we take another look at the dimming antics of Betelgeuse, which is up to those old tricks again. Research from Hubble helped understand last winter’s event. And Ganymede is covered with one massive crater as a result of a giant impact four billion years ago.
Mission updates: Arecibo suffers damage, OSIRIS-Rex performs final rehearsal, TESS completes primary mission, plus guest Kynan Hughson talks Ceres
Join us today as we share some mission updates, good and bad. The bad: Arecibo Observatory suffered damage from a snapped cable. The good: OSIRIS-Rex performed a final dress rehearsal for taking a sample of Bennu and NASA’s TESS finished its primary mission. Plus, we’re joined by postdoc Kynan Hughson to talk about this week’s Ceres news!
