The students are selling dragonfly pendants to support their cosmic ray ballooning program. The dragonfly's heart is a golden Celtic love knot, and its wings are decorated with a spray of rainbow-colored crystals. On June 3, 2022, this sterling silver pendant hitched a ride onboard an Earth to Sky Calculus cosmic ray research balloon: STERLING SILVER RAINBOW DRAGONFLY: Are you looking for a far-out gift? Consider a rainbow dragonfly from the edge of space.

Its Near-Infrared Camera (NIRCam) has a filter that nicely captures the 3.3 to 3.6 micron glow of H3+. In fact, the telescope is well instrumented to monitor these auroras. Two distinct auroras coexist over the poles of Jupiter: Ultraviolet auroras created by atmospheric hydrogen in its molecular form (H2) and infrared auroras created by the hydrogen ion H3+. Io is already inside Jupiter's "defenses," so it can be more effective. Also, Jupiter's powerful magnetic field forms a potent shield. However, solar storm clouds are naturally weakened by the time they travel all the way to Jupiter, five times farther from the sun than Earth. Jupiter's volcano-powered auroras are usually "on."Ībove: This JWST image of Jupiter and its surroundings uses a different color table, so the auroras look blue. The resulting glow can be seen almost anytime JWST wants to look. Polar electric fields grab these ions and slam them into Jupiter's upper atmosphere. The fuel comes from Jupiter's volcanic moon Io, where active vents spew ions such as O+ and S+ into Jupiter's magnetosphere. These voltages set the stage for non-stop auroras. Jupiter's spin produces 10 million volts around its poles. Spinning a magnet is a great way to generate a few volts kids do it all the time for science fair projects. Jupiter turns on it axis once every 10 hours, dragging its giant planetary magnetic field around with it. One of the key ingredients is volcanoes, and-so much for space weather-solar activity is not required.įor the most part, Jupiter makes its own Northern and Southern Lights. They are formed in a completely different way.

The camera's F360M filter picked up the 3.3 - 3.6 micron glow of excited H3+ in Jupiter's auroral zone.īut Jupiter's auroras are more then just oversized versions of our own.

The red rings of light circling Jupiter's poles were big enough to swallow Earth: Solar flare alerts: SMS TextĪURORAS ON JUPITER: This week, NASA released the first James Webb Space Telescope (JWST) images of auroras on Jupiter. No CMEs are coming, and the next solar wind stream isn't expected to reach Earth until Aug. Neutron counts from the University of Oulu's Sodankyla Geophysical Observatory show that cosmic rays reaching Earth are slowly declining-a result of the yin-yang relationship between the solar cycle and cosmic rays.ĪLL QUIET: Barring an unexpected solar flare (full disclosure: almost all solar flares are unexpected), space weather should remain calm for the rest of the week. Credit: SDO/HMIĬosmic Rays Solar Cycle 25 is beginning, and this is reflected in the number of cosmic rays entering Earth's atmosphere. All of these sunspots have stable magnetic fields that pose little threat for strong flares.
