Pulsars as the Particle Accelerators of the Universe

Pulsars as the Particle Accelerators of the Universe

Fast, strong magnetic winds caused by quickly rotating pulsars may be accelerating particles like electrons to extremely high-energy states and creating gamma-ray photons in their wake. Plus, missions close to home, large and distant objects, some pretty Hubble photos, and laser simulations of fast radio bursts.

New Fossil Data Shows Cascadia’s Dangers

New Fossil Data Shows Cascadia’s Dangers

An analysis of sediment core samples taken at the Salmon River Estuary in Oregon provides evidence that the massive 1700 Cascadia earthquake caused 15 meters of slip along the shoreline, which lead to over a meter of coastal subsidence. Plus, all the rocket launches, a few mission updates, making Mars bricks with urea, and an interview with Maggie Thompson from UC Santa Cruz about using methane as a biosignature.

Early Bacterial Life May Have Formed Far Earlier Than Thought

An analysis of microscopic features in rocks from the Nuvvuagittuq Supracrustal Belt in Quebec, Canada, which date back between 3.75 and 4.28 billion years, finds evidence of possible microbial life. Plus, a supermassive black hole precursor, temperatures on Neptune, check-ins with various spacecraft, and our weekly What’s Up segment.

Perseverance Images Confirm Jezero Crater as Ancient Lake

Perseverance Images Confirm Jezero Crater as Ancient Lake

A newly completed analysis of Perseverance’s first images from Mars finds that the landing site, Jezero Crater, was really a lake that was fed by a river, with sedimentary layers, flash floods, and strewn boulders. Plus, Central African biomass burning, Arctic permafrost melting, and we look at jewelry that celebrates upcoming missions.
