Betelgeuse Smaller Than Previously Calculated, Still Mystery

Scientists collected fresh data on Orion’s bright star Betelgeuse to try and understand this star that caused so much controversy last year. They found it’s smaller than previously calculated, and last year’s dimming was likely caused by dust, but it’s also more complex than thought. Plus, galaxies, Earth’s forests, ice on Mars, and Saturn’s moon Rhea.

Why pulsars shine brightly; Antares’ atmospheric layers; Volcanic craters on Titan

Join us today as we consider a new paper on why pulsars shine so brightly (hint: it’s those pesky magnetic fields). We take a look at new images of Antares’ massive atmospheric layers. Finally, we share a story from our own Planetary Science Institute: evidence has been found that there are volcanic craters on Saturn’s moon, Titan.

Titan moving away from Saturn; Infrared photos of Phobos; Hints of new volcanism in Europe

Join us today as we analyze news that Titan is moving away from Saturn more quickly than previously thought. Also, we look at recent photos of Mars’ moon Phobos taken by NASA’s Mars Odyssey. Finally, we note that there is possibly new volcanic activity underneath Germany. After those stories, we interview Dr. Jamie Molaro from PSI about her recent paper on asteroid Bennu.
