Starts With A Bang #129 - Triton and the outer solar system
<p>We often think about the Solar System as being our own cosmic backyard, and in many ways, it is: these are the closest objects to us in all the Universe, and our only opportunity to study lunar and planetary systems in situ. However, when it comes to the objects beyond Saturn, including the Uranian and Neptunian systems, as well as everything that lies in the Kuiper belt and beyond, the only probes we've ever sent their way are Voyager 2, which flew by Uranus and Neptune in the late 1980s, and New Horizons, which flew past Pluto in 2015.</p><p>That means, unlike Jupiter and Saturn, we've never had a dedicated orbiter, lander, or atmospheric probe around the outermost planets or lunar systems even in our own backyard. Moreover, there are no such planned missions that are funded and slated to fly, which is really too bad, as there's so much to learn about these planets and worlds that are so well-represented in exoplanet analogues all across the galaxy and Universe. In particular, one moon stands out as the largest body with a solid surface: Triton, the 7th largest moon in the Solar System and which represents more than 98% of the mass of all the moons that orbit Neptune.</p><p>Here to guide us through the far reaches of our Solar System, I'm so pleased to welcome PhD candidate Lana Tilke to the program. There's a whole lot of ground that we cover, and the conversation left me inspired with the questions that we're asking today, and brimming with hope that we take the steps we needed to answer them. If you'd like to know where we are and where we're headed next, you just might love this episode too!</p><p>(This image shows a composite of Neptune's giant moon Triton, assembled from Voyager 2 imagery at the highest possible resolution. The dark streaks come from cryovolcanic geysers, also known as black smokers, from Triton's south polar region. <a href="https://www.planetary.org/space-images/triton-from-voyager-2" target="_blank" rel="noopener noreferrer nofollow">Credit</a>: NASA/JPL)</p>

Starts With A Bang #128 - Planet formation and proto-protoplanets
<p>Whenever a new star forms, several processes appear to be nearly universal. A cloud of cold molecular gas contracts, fragments, and rapidly collapses in certain places. The densest, coldest clumps of gas contract first, drawing in larger and larger amounts of matter onto them. A large, massive enough clump will heat up and have a random shape: collapsing along the shortest axis first, forming a protostar at the center surrounded by a disk of material. That's where the story of planet formation begins.</p><p>Assuming the conditions in the disk are sufficient, clumps will begin to form, and over hundreds of thousands to millions of years, the first protoplanets and then full-fledged planets will arise: a relatively rapid cosmic process, that's usually all complete within a mere 10 million years: a blink of a cosmic eye in the history of our own 4.5 billion year old Solar System. However, by looking at the youngest stellar and planetary systems, we can uncover many details that are common to planetary systems in general, and in turn, we can learn how our own Solar System grew up.</p><p>This fantastic episode of the Starts With A Bang podcast features observational astrochemist Dr. Charles Law, and takes us inside one of the most remarkable young stellar systems ever found: the edge-on system known as Gomez's Hamburger, complete with a first-of-its-kind exoplanet known as GoHam b. Come find out the incredible science behind planet formation, and meet our first-ever proto-protoplanet in the process!</p><p>(This JWST NIRCam image shows many never-before-revealed details in the dusty disk of the edge-on protoplanetary system known as Gomez's Hamburger, with a massive, unique exoplanet within the disk known as GoHam b. <a href="https://commons.wikimedia.org/wiki/File:GoHam_JWST_NIRCam_short.jpg" target="_blank">Credit</a>: NASA/ESA/CSA JWST; Francois Menard et al.)</p>
