Webb maps Uranus's mysterious upper atmosphere
Thursday, 19 February 2026 13:00
For the first time, an international team of astronomers have mapped the vertical structure of Uranus’s upper atmosphere, uncovering how temperature and charged particles vary with height across the planet. Using NASA/ESA/CSA James Webb Space Telescope's NIRSpec instrument, the team observed Uranus for nearly a full rotation, detecting the faint glow from molecules high above the clouds. The results offer a new window into how ice-giant planets distribute energy in their upper layers.

Study revisits chances of detecting alien technosignatures

Sydney, Australia (SPX) Feb 19, 2026
For more than sixty years, astronomers have searched the sky for signs of advanced extraterrestrial technology, scanning the Milky Way for artificial radio transmissions, optical flashes and excess infrared heat.
Despite these efforts, no technosignature has been confirmed so far, a silence often attributed to the fact that only a tiny fraction of the cosmic search space has been explored.

The results from our first visit to the "Nevado Sajama" drill location were intriguing enough to motivate our return to do a deeper dive into the minerals and compounds locked in this rock with SAM (the Sample Analysis at Mars instrument suite).
As explained in the last blog, that deeper dive involves using the second of two vials of a chemical reagent, tetramethylammonium hydroxide (TMAH)
