Did you know about these?

Some of the most unusual space mysteries may be right in our solar system.  We’re often discussing galaxies, quasars and exoplanets with mysterious formations at great distances.  In actuality there are some huge mysteries to this day that are still unanswered.  Here is the video intro:

We’ve also discovered nearly 1,800 planets around other stars. It would be easy to think that we’ve got a pretty good handle on what’s out there. Then you find out that there’s a bizarre giant hexagon on Saturn, and you realize that we don’t understand half of what’s going on with our closest neighbors. These mysteries make it clear we’re going to need a lot more robots.

Here is a list of these 5 mysteries and the video does a great job of giving a quick background of each one:

5.  The Venus Vortex

4.  The Very Mysterious Lapetus

3.  The Spider On Mercury

2.  Plumes On Ceres

1.  Io’s Out Of Place Volcanos

Here is a bit more on Io from wikipedia:

Io/ˈaɪ.oʊ/^[6] is the innermost of the four Galilean moons of the planet Jupiter. It is the fourth-largest moon, has the highest density of all the moons, and is the driest known object in the Solar System. It was discovered in 1610 and was named after the mythological character Io, a priestess of Hera who became one of Zeus‘s lovers.

Io is the most geologically active object in the Solar System. This extreme geologic activity is the result of tidal heating from friction generated within Io’s interior as it is pulled between Jupiter and the other Galilean satellites. Io’s surface is also dotted with more than 100 mountains that have been uplifted by extensive compression at the base of Io’s silicate crust. Some of these peaks are taller than Mount Everest. Unlike most satellites in the outer Solar System, which are mostly composed of water ice, Io is primarily composed of silicate rock surrounding a molten iron or iron sulfide core. Most of Io’s surface is composed of extensive plains coated with sulfur and sulfur dioxide frost.
