After over 35 years of trying, NASA finally confirmed Neptune has auroras. They did this when astronomers were able to capture images of them using the James Webb Space Telescope.
According to the James Webb Space Telescope website, “Webb’s detection of auroras on Neptune is the first time astronomers have captured direct evidence of this phenomenon on the planet most distant from the Sun…
“Neptune’s auroras do not occur at the northern and southern poles of the planet, where we see auroras on planets like Earth and Jupiter, because of the strange nature of Neptune’s magnetic field, which is tilted by 47 degrees from the planet’s rotational axis,” it further explained.
“Webb’s study of Neptune also revealed that the planet’s upper atmosphere has cooled by several hundred degrees, likely the reason that Neptune’s auroras have remained undetected for so long.”
“At the left, an enhanced-color image of Neptune from NASA’s Hubble Space Telescope,” the Webb Space Telescope website explains. “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…more
