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.
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.
The most precise measurements of the universe’s composition and growth have been reported in almost thirty new papers based on Dark Energy Survey observations of 229 million galaxies and covering one-eighth of the sky. Plus, stories from the first day of the AAS conference, all the volcanoes, and mission updates.
Fermilab released the first results of their Muon g-2 experiment this week, and the fundamental particles don’t behave as predicted by the Standard Model of Particle Physics. Plus, dust, more dust, Martian water (again), and a review of Packing for Mars by Mary Roach.
We interview a pair of scientists who have examined microorganisms embedded in halite crystals to determine the feasibility of finding similar evidence of past life in return samples from Mars. Plus, ‘Oumuamua, Bennu, Ryugu, winds on Jupiter and a space jellyfish.
