Unlocking the Secrets of WASP-121b with JWST
Using JWST's NIRSpec, researchers precisely measured the mass, age, and atmospheric dynamics of the ultra-hot Jupiter WASP-121b and its host star. They discovered strong winds in the planet's atmosphere and achieved unprecedented precision in mass and age estimates, revealing a 1.11-billion-year-old system. This study showcases JWST's transformative role in advancing exoplanet research.
Exploring Martian Winds with Ingenuity: The First Near-Surface Wind Profiling on Mars
The Mars Ingenuity helicopter has been repurposed to study near-surface winds, providing unprecedented data on wind speeds and directions at altitudes between 3 and 24 meters. Ingenuity’s telemetry data, analyzed by Brian Jackson's team, showed winds significantly stronger and sometimes in different directions than predicted by Mars climate models, suggesting complex local wind dynamics influenced by terrain around Jezero Crater. These findings highlight the potential of drones to deepen understanding of Martian atmospheric layers and improve future exploration models and planning.
