What are X-rays?
A type of electromagnetic radiation
The machines used in hospitals for radiographies
A musical band
The light produced during the storms
Do planets emit X-rays by themselves like the Sun does?
Yes, they are very hot
Yes, they have a nuclear bomb inside
No, they do not contain hot gas
No, they rotate too fast
In Jupiter and Saturn we see X-rays because...
There are many hospitals using their X-rays machines there
They burn gas, like our Sun and emit X-rays

Bioluminiscence
Jupiter's auroras are produced by "Charge Exchange"
Which of these is the best explanation?
There are volcanoes in Jupiter which expel colorful particles to the atmosphere
The electrical storms in Jupiter emits lightnings which are visible in X-rays
Molecules in Jupiter poles exchange their protons and electrons to form new molecules, emitting X-rays
Highly charged particles steal electrons from molecules in the atmosphere of Jupiter and then emit X-rays
Saturn rings are bright in X-rays because...
They are made of radioactive material
Many supernova explosions are produced ther
They are very hot, at millions of degrees, and shine bright like the Sun
