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!
Two new studies used data from Cassini’s Grand Finale observations of Saturn and found that the magnetic fields and a wave in the rings provide insight into the core structure and composition of the gas giant. Plus, cosmic rays, how Mayans shaped the Earth, and a review of books by Charles C. Mann.
New research looking to explain the “missing” portion of baryonic matter in the universe managed to locate the material lurking in intergalactic space as hot, low-density gas. Plus, supercontinents, Enceladus, and weird earthquakes.
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.
USGS volcanologists and seismologists have been working around the clock to collect data on Kīlauea’s latest eruption after two years of dormancy. Plus, all the volcano news you can handle, as well as a meteorite, an asteroid, and a comet, oh my!
Scientists using Hubble to track storms on Neptune found that a current storm has reversed direction and possibly shed a fragment. Plus, an update on Hayabusa2’s sample return, a non-technological radio emission from an exoplanet, This Week in Sky Watching, and more!
