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.

Another Potential Dark Matter Particle Isn’t Found

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.

Strong Evidence Found That Muons Deviate From Standard Model

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.

“Missing” Matter Found in Intergalactic Space

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.

The IceCube Neutrino Observatory in Antarctica detected an electron antineutrino, confirming another piece of the Standard Model and proving that neutrino astronomy is feasible. Plus, a meteorite, wormholes, zodiacal light, and our weekly What’s Up segment.

New Type of Dark Energy Proposed Could Solve Conflicting Calculations

Issues with calculating the expansion rate of the universe have led to differences in the results, depending on the method used. A pair of physicists have proposed a new type of dark energy to resolve the conflict. Plus, volcanic ash and volcanoes, the composition of the Sun, more exoplanets, and Mars’ moons.
