You know we love 1) Neptune (love them nep-toots) & Aurora, so this new image from #JWST is *perfection*

If you too love Neptune, check out our episode on the Nereids, where we explore some of Neptune's moons: starrytimepodcast.podbean.com/

If you love aurora, check out our episode on the science & lore of Earth's aurora: starrytimepodcast.podbean.com/

From source in toot: At the left, an enhanced-color image of Neptune from NASA’s Hubble Space Telescope. At the right, that image is combined with data from NASA’s James Webb Space Telescope. The cyan splotches, which represent auroral activity, and white clouds, are data from Webb’s Near-Infrared Spectrograph (NIRSpec), overlayed on top of the full image of the planet from Hubble’s Wide Field Camera 3.

At last, auroras have been spotted on every planet in the solar system, thanks to the James Webb Space Telescope. The JWST’s powerful near-infrared spectrometer recently revealed Neptune’s elusive aurora in all its gently glowing glory.

Discovery of H3+ and infrared aurorae at #Neptune with JWST: nature.com/articles/s41550-025 -> Webb captures Neptune's auroras for the first time: esawebb.org/news/weic2507/ and webbtelescope.org/contents/new

NatureDiscovery of $${{\bf{H}}}_{\mathbf{3}}^{\mathbf{+}}$$ H 3 + and infrared aurorae at Neptune with JWST - Nature AstronomyJWST has detected $${{\rm{H}}}_{3}^{+}$$ H 3 + and auroral emissions at Neptune—the only giant planet in the Solar System for which they had proved to be elusive up to now. The observations reveal a factor-of-two cooling of Neptune’s upper atmosphere compared with Voyager 2 data, indicative of energy balance processes acting on a shorter timescale than solar forcing.

A neat story by @DrCarpineti: "'This is the quadfecta, completing the set of observing auroral emissions from all of the four giant planets in the infrared. We knew it should be there since Neptune has all the ingredients you need to create aurorae, but we were never able to detect it using telescopes on the ground.'"

HUGE EXLOSION IN #TUAPSE #REFINERY: LONG NEPTUNE FIRST STRIKE Vlog 983: War in Ukraine

Ukraine's defense industry has extended the range of the #Neptune cruise #missile. The Ukrainian missile can now strike targets up to 1,000 kilometers away. This was announced by President of #Ukraine #VolodymyrZelenskyy.  The "#LongNeptune" has already undergone testing and successful combat use with precise hits.
