DOI: 10.3389/fspas.2022.886670″ width=”796″ height=”528″/> Evolution of the solar dipole and multipole components from the Wilcox Solar Observatory expansion of the coronal magnetic field. Dashed lines represent terminators; dotted lines represent the pre-terminators. The red arrow corresponds to the Halloween Storms of 2003—note the drop in dipole moment (top … Read more

Stellar Flybys Leave a Permanent Mark on Newly Forming Planetary Systems

What do UX Tauri, RW Aurigae, AS 205, Z CMajoris, and FU Orionis have in common? They’re young stellar systems with disks where planets could form. It appears those disks were disturbed by stellar flybys or other close encounters in the recent past. Astronomers want to know: did those events disrupt planet formation in the … Read more

Newly discovered carbon may yield clues to ancient Mars — ScienceDaily

NASA’s Curiosity rover landed on Mars on Aug. 6, 2012, and since then has roamed Gale Crater taking samples and sending the results back home for researchers to interpret. Analysis of carbon isotopes in sediment samples taken from half a dozen exposed locations, including an exposed cliff, leave researchers with three plausible explanations for the … Read more
