This timelapse\u00a0shows\u00a0a full rotation of Uranus\u00a0captured\u00a0by\u00a0NASA\/ESA\/CSA James Webb Space Telescope. Thanks\u00a0to its\u00a0orbit at L2,\u00a0Webb\u00a0was able to\u00a0observe\u00a0the planet for approximately 17 hours\u00a0continuously.\u00a0<\/p>\n
The\u00a0video consists of over 1200 slices of multi-object spectroscopy data. By mapping distribution and temperature of hydrogen\u00a0in its\u00a0molecular\u00a0and\u00a0trihydrogen\u00a0form, these observations provide the most detailed view to date of Uranus\u2019 vertical upper atmosphere. The video shows where temperatures and densities\u00a0of\u00a0charged particles\u00a0peak, and reveals clear auroral structures shaped by the planet\u2019s unusual magnetic field.<\/p>\n
Using Webb\u2019s\u00a0NIRSpec instrument, the team detected the faint glow from molecules high above the clouds. These unique data provide the most detailed portrait yet of where the planet\u2019s auroras form, how they are influenced by its unusually tilted magnetic field, and how Uranus\u2019s atmosphere has continued to cool over the past three decades. The results offer a new window into how ice-giant planets distribute energy in their upper layers.<\/p>\n
