Jupiter is shown in visible light for context underneath an artistic impression of the Jovian upper atmosphere’s infrared glow. The brightness of this upper atmosphere…
In geospace, the Arase satellite observes chorus waves and energetic electrons, while on the ground, EISCAT and optical instruments observe pulsating aurorae and electron precipitation…
NASA’s Juno Mission observed pulsating electromagnetic ion cyclotron waves in Jupiter’s dawn magnetosphere that periodically expel energetic heavy ions into the atmosphere, producing stunning X-ray…
The purple hues in this image show X-ray emissions from Jupiter’s auroras, detected by NASA’s Chandra Space Telescope in 2007. They are overlaid on an…
Jupiter’s mysterious X-ray auroras have been explained, ending a 40-year quest for an answer. For the first time, astronomers have seen the way Jupiter’s magnetic…
Physicists led by the University of Iowa report definitive evidence that auroras that light up the sky in the high latitudes are caused by electrons…

The SwRI-led Ultraviolet Spectrograph (UVS) orbiting Jupiter aboard NASA’s Juno spacecraft allowed scientists to discover faint aurora features likely triggered by charged particles coming from…
The Arase satellite captured data about electrons accelerated from very high altitudes. Credit: ERG science center Electrons arriving from the Sun are propelled by electrical…
From the International Space Station’s orbit 269 miles above the Indian Ocean southwest of Australia, this nighttime photograph captures the aurora australis, or “southern lights.”…
Low-energy (blue) and high-energy (yellow) electrons form during the process that generates the pulsating aurora. The high-energy ‘relativistic’ electrons could cause localized destruction of the…
Taken July 17, 2018, at Little Kenosee Lake, Saskatchewan, Canada, this photo shows the tiny green streaks below STEVE. Neil Zeller, photographer and co-author on…
