A ninth-magnitude star in our neighborhood of the Milky Way has been found to contain 65 different elements, including large proportions of heavier elements like gold. This star required either a supernova or a neutron star merger to form. Plus, another solar flare, a strong marsquake, cosmic rays, cookies, and this week in rocket history, we look back at STS-84.

An analysis of images taken by the Spirit rover of olivine-rich rocks in Gusev crater has revealed a much more violent volcanic origin than originally thought and one that likely occurred early in Mars’s history. Plus, balloon science, more Mars, more volcanoes, pretty Hubble images, and What’s Up (a supernova!).

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.

An analysis of the relative movements of 18 tectonic ridges over the past 19 million years finds that the rate of seafloor spreading has dropped by about 40% on average globally. Plus, stars are getting naked, climate change is heating things up, and we review “Impact: How Rocks from Space Led to Life, Culture, and Donkey Kong” by Greg Brennecka.

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.
