NASA’s Perseverance Rover Touches Safely Down on Mars
Six-Exoplanet System in Resonance, Challenges Formation Theories
It’s a day ending in ‘y’, and planetary formation theories are once again being challenged. This time the challenge comes from a six-planet system with five planets in resonance. Plus a cloudless Jupiter, TRAPPIST-1, volcanoes, and some science of the weird.
Anatomical Dissection of Planetary Nebula Using Hubble Images
Our coverage of last week’s AAS meeting continues with new work on the formation of planetary nebula based on Hubble Space Telescope images. Plus, a massive quasar in the early universe, water ice on Ganymede, a super-puff planet, and plans for taking spectra of Venus’ surface, featuring our guest, PSI scientist Dr. Darby Dyer.
Climate Change Affects Harvest, Rocks, Shorelines… and Truffles?
Climate change is a leading problem in today’s society, and today we have a quartet of stories on its effect on the world around us. Plus, more coverage from the AAS meeting with three stories on black holes, as well as dating supernovae, breaking a star, and magnetic chaos in a galaxy.
Missing Black Hole Continues to Mystify Scientists
A massive black hole should be in the galaxy cluster Abell 2261. Observations with Chandra and Hubble haven’t located it. Plus, classifying supernovae with AI, neutron stars, the lithium composition problem, and more planetary science.
