NASA solves mystery of Jupiter’s X-Ray Auroras:


Context:

Jupiter has Auroras near both its poles  which emit X-rays. However, scientists were puzzled about the reason behind these X-Ray emissions.

 

What’s the reason behind this phenomenon?

Auroras are caused by ions crashing into Jupiter’s atmosphere. These ions are ‘surfing’ the electromagnetic waves in Jupiter’s magnetic field to enter the planet’s atmosphere.

 

About Juno:

Juno was launched in 2011 on a mission to study Jupiter’s composition and evolution. It’s the first spacecraft to orbit Jupiter since Galileo.

  • Juno’s primary goal is to reveal the story of Jupiter’s formation and evolution.

 

XMM-Newton mission:

Also known as the High Throughput X-ray Spectroscopy Mission and the X-ray Multi-Mirror Mission, it is an X-ray space observatory launched by the European Space Agency in December 1999.

  • It is part of ESA’s Horizon 2000 programme.
  • The spacecraft is tasked with investigating interstellar X-ray sources, performing narrow- and broad-range spectroscopy, and performing the first simultaneous imaging of objects in both X-ray and optical (visible and ultraviolet) wavelengths.
