Dec 17, 2021 | AGU, Climate Change, Curiosity, Daily Space, Earth, Mars, Our Solar System, Perseverance, Rovers, Sky Watching, Star Forming Region, The Sun, Venus

A team of scientists collected cores and modeled ice cliff failure and found that Thwaites Glacier in Antarctica is melting more quickly than ever and could be at risk of collapse, threatening global coastlines with almost a meter of sea-level rise. Plus, new results from Percy, and this week’s What’s Up.

Cosmic Billiards Leads to Inner Planetary Growth

The inner solar system was a wild and wooly place as the planets were forming, and new research shows that the collisions that formed Earth and Venus were likely of the hit-and-run variety. Plus, polar ice loss warps the planet, and a black hole eats a star.

Supervolcanoes Remain Active Post-Eruption Longer Than Thought

Research into the Toba caldera and its super-eruption 75,000 years ago shows that magma continued to flow out of the volcano for thousands of years after the main eruption event. Plus, magma and volcanoes throughout our solar system as well as our weekly What’s Up segment.

Using a neutron spectrometer on board the Dawn spacecraft, scientists have found elevated concentrations of hydrogen in Ceres’ Occator Crater, which provides evidence of an icy crust. Plus, everything is on fire in the western United States, and we review “The Past is Red” by Catherynne M. Valente.

NASA’s OSIRIS-REx Finds Bennu Collision Risk Nearly Nonexistent

After careful analysis of orbital data, gravitational forces, and several other factors, NASA’s OSIRIS-REx team calculated the risk of a collision with near-Earth asteroid Bennu to be 0.057% through 2300. Plus, magnetites in meteorites reveal solar system history, and the constellation Ophiuchus is What’s Up.

NASA Identifies Possible Lunar Mantle Rocks on Lunar Surface
