Sep 17, 2021 | Daily Space, Earth, Jupiter, Mars, Mercury, Sky Watching, Venus

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.

Simple Physics Explains Diamond Shapes of Ryugu and Bennu

Using data collected by NASA’s Kepler Space Telescope, scientists have found four free-floating, or rogue, planets near the core of the Milky Way. These planets formed in discs in other planetary systems and were thrown out by gravitational interactions with larger planets. Plus, the early solar system, including ancient Earth, Jupiter’s chemistry, and Mercury’s core.

Europa May Have Enough Heat for Seafloor Volcanoes

Jupiter’s moon Europa, an icy world with a subsurface ocean that interests astrobiologists, may actually be hot enough to melt the interior rock and create volcanoes on the ocean floor. Plus, Ryugu, giant planets, fossil discoveries, Martian glaciers, and this week’s What’s Up!

“Missing” Matter Found in Intergalactic Space
