TOP ASTRONOMICAL MYSTERIES 

1.    Earth’s Solar System has differences that aren’t easily explained, compared to discoveries of alien planets around other stars. Such as the position of the gas giants and a possible as yet undiscovered exoplanet.

2.    The Sun's corona puzzles scientists because its ultra-hot outer atmosphere reaches 10.8 million degrees and coronal heating that occurs in the sun's upper atmosphere.

3.    Cosmic rays flow into the solar system from deep space, the origin and great strength (100 million times more than manmade collider particles) of these subatomic particles is a mystery.

4.    Supernovas are fuel depleted massive stars that blast so bright they outshine galaxies. Scientists want to understand what happens inside a star before the ignition.

5.    Reionization of the universe occurred right after the big bang in an age when hydrogen gas cleared and became translucent to ultraviolet light. These processes are not understood.

6.    Dark energy makes up 73% of the universe, theories state it is pulling the universe apart. Astronomers use it to explain the rapidly expanding universe.

7.   
Dark matter is invisible, has mass--23% of the universe-- but can’t be seen. Its presence is detected by gravitational pull on other objects.

8.    Missing Baryons make up the missing 5% and science suspects they may be found between galaxies in intergalactic medium but can only account for half of this material.
