Every 27 minutes, there’s an X-ray aurora on Jupiter. Here’s why.

Jupiter's mysterious auroral events are caused by vibrating waves of plasma.

  • For 50 years, astronomers have known that Jupiter has frequent auroral displays, but not why.
  • The bursts are a combination of visible and invisible light.
  • The presence of NASA's Juno spacecraft around Jupiter allowed scientists to solve the mystery.

Jupiter’s intense radiation makes its moon Europa glow

Using a laboratory model, scientists get a nice Jovian surprise.

  • Europa is continually bombarded by radiation from Jupiter.
  • According to new research, that radiation may make the moon glow.
  • The colors of the glow may help scientist identify Europa's compounds.

    • The Juno space probe orbiting Jupiter has observed lightning at impossibly high points in the Jovian atmosphere.
    • The findings, combined with other atmopsheric data, led to the creation of a new model of the atmosphere.
    • The findings answer a few questions about Jupiter, but create many more.
