A new paper looks at marsquakes and what is causing them, which turns out to be magma moving. And Curiosity has found rocks it needs to go around. Then there is the weather on Mars. Plus, lunar formation, a giant comet, and this week in rocket history, we look back at Apollo 13.
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.
After detecting high levels of organic matter using remote sensors at the asteroid Ryugu, numerical models show that it’s possible that rubble pile asteroids are actually extinct comets. Plus, the Cosmic Optical Background, Enceladus’s tiger stripes, and this week in rocket history, we look back at STS-45.
Using updated stellar measurements based on new data from the Gaia mission, three (and possibly four) Kepler exoplanets are actually small stars, but it’s unlikely new calculations will reveal many more such issues. Plus, Ingenuity, astronauts, permafrost, and This Week in Rocket History, we look back at STS-3 and the first use of the Canadarm.
The Advanced Camera for Surveys instrument onboard the Hubble Space Telescope is celebrating twenty years of service this week. Plus, a new look at an old lunar rock, gas rings around an aging star, all the rockets from around the world, and this week in rocket history, we look back at the 1962 Orbiting Solar Observatory, led by Nancy Grace Roman.
To bring some joy into a fraught world, we have rounded up a few of the latest image releases of star mergers and galaxies to brighten your day. Plus, we’ll look at a few strange exoplanetary systems and their amazing science, talk about the latest GOES satellite to launch, and this week in rocket history is all about Envisat.
