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.

From plastics invading the Arctic Ocean to the changing morphology of birds in response to rising temperatures and the problems with pathogens killing off pollinators like bees, we examine some of the effects of climate change on Earth’s ecosystems. Plus, Ganymede, moonlight, solar cells, and this week in rocket history, we look back at STS-83.

Researchers pouring through high-resolution Hubble images of galaxy clusters have found the gravitationally magnified light of a star that was shining just four billion years after the Big Bang, making this bright star the new record holder for the farthest ever spotted. Plus, some launches, ice volcanoes on Pluto, melting Arctic ice, and this week in rocket history, we look back at INSAT.

Computer models of the effects of an eruption event similar to the Columbia River Flood Basalt show that, despite massive injections of sulfur dioxide into the atmosphere, Earth’s climate rebounded much more quickly than expected. Plus, ORCs, lunar swirls, exoplanets, and diamonds.
