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.
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.
Two new studies have possibly identified regions on the Moon’s surface that could contain pieces of the lunar mantle, which would be possible sample targets for the Artemis mission. Plus, Venus gets a double flyby next week, and it’s all about asteroids and meteor showers in this week’s What’s Up.
In three new papers released this week, scientists analyzed data from NASA’s InSight lander to reveal the structure of Mars and its layers, revealing information about the planet’s crust, lithosphere, mantle, and core. Plus, isotopes in an exoplanet’s atmosphere, a potential exomoon being formed, the heart of a radio galaxy, and black holes impeding stellar birth.
Minor planet 2014 UN271, discovered in data collected by the Dark Energy Survey, is set to make a close pass to Saturn’s orbit at the end of the decade, giving astronomers a chance to observe a rare trans-Neptunian object from up close…ish. Plus, Venus, Jupiter, the Milky Way, and an invisible galactic structure discovered quite by accident.
Contrary to the destructive role supermassive black holes are thought to play in the lives of stars, it turns out that certain types of galaxies benefit from black holes clearing the way and keeping star formation going. Plus, lightning at the edge of space, a landslide in the Himalayas, and an interview with Dr. Darby Dyar and Dr. David Grinspoon about the recent selection of three different Venus missions.
