The gas-giant orbiter is illuminating the provenance of Jovian polar light shows.
New results from the Ultraviolet Spectrograph instrument on NASA’s Juno mission reveal for the first time the birth of auroral dawn storms – the early morning brightening unique to Jupiter’s spectacular aurorae. These immense, transient displays of light occur at both Jovian poles and had previously been observed only by ground-based and Earth-orbiting observatories, notably NASA’s Hubble Space Telescope. Results of this study were published March 16 in the journal AGU Advances.

The Juno spacecraft of the National Aeronautics and Space Administration (NASA) has revealed the dark origins of Jupiter s mysterious auroral storms, in a recent study.
The findings of the research, published in the journal AGU Advances state that the Ultraviolet Spectrograph instrument of the Juno mission, the gas-giant orbiter is illuminating the provenance of Jovian polar light.
It reveals for the first time the birth of auroral dawn storms – the early morning brightening unique to Jupiter’s spectacular aurorae. These immense, transient displays of light occur at both Jovian poles and had previously been observed only by ground-based and Earth-orbiting observatories, notably NASA’s Hubble Space Telescope.
A spectacular and dramatic ultraviolet auroras on Jupiter is generated by charged particles escaping its volcanic moon Io, according to a new NASA study.
The origins of the bright blue circular aurora were revealed by the NASA Juno spacecraft, which is currently studying the gas giant from orbit.
The Jovian polar light show, also known as the auroral dawn storms, brighten up the early morning north and south poles of the massive world.
These immense, transient displays of light evolve in a similar way to aurora substorms that undulate across Earth s polar skies, according to NASA and the University of Liège team behind the new discovery.

Twenty five years ago, on March 7, 1996, the first image-based surface map of Pluto was released. Sixty six years after it had been discovered, astronomers finally saw details on its surface directly. While we have had better images of the dwarf planet since, A.S.Ganesh takes a look at these first images and how they helped us understand Pluto better.
