In a new paper, a renowned physicist’s overview of recent observations shows that the gap in the universe expansion calculations is closing. The Standard Model may be fine after all. Plus, Mars’ methane mystery, an orphan cloud, galaxies moving to collide, and an interview with PSI’s Than Putzig about just what is under Mars’ south polar ice cap.
The fossilized teeth and bones of baby dinosaurs found in northern Alaska may indicate that dinosaurs didn’t just summer in the Arctic but nested and raised their young there. Plus, the cosmic dawn, a cosmic hand, black holes, and preserving core samples for the future of science.
The biggest mass extinction event on Earth occurred at the end of the Permian period, resulting in the extinction of 95% of marine life and 80% of terrestrial life. Now, scientists have found that the terrestrial portion of the event lasted nearly ten times as long as the ocean version. Plus, a spaghettified star, the search for Moon Trees, all about Mars, and new works on dark matter and dark energy.
Researchers looked for a slowdown in black hole rotational speeds due to the collection of ultralight bosons, but they found nothing, eliminating the hypothetical particle from the list of possible dark matter particles. Plus, neutrino hunting, neutron stars, a space hurricane, and our review of some delightfully nerdy apparel.
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.
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.
