Jupiter IV - Calisto - NASA reports that Callisto is the third largest satellite in the solar system and roughly the size of Mercury. NASA points out that its many markings show a turbulent history of collisions with space objects. In fact, Callisto is known to be the most heavily cratered object in our solar system. And while Callisto is uniformly cratered, it is not uniformly colored. Experts believe the different colours come from ice and ice erosion.

The second solar flare on Oct. 25, 2013 at 15:00 UTC was seen by NASA's SDO in the far ultraviolet, a wavelength of light where flares are particularly bright.

タイタンは土星最大の衛星で、直径約5150km。窒素とメタンの分厚い大気に覆われ、地表温度はマイナス170度。地球のような水循環はないものの、メタンなどの炭化水素が液体状態で存在していると考えられている。特にカッシーニ土星探査機のこれまでの観測で、タイタンの北極には多数のメタンの湖が集中して存在していることが確認されている。

The red planet Mars, as seen by the Hubble Space Telescope. Can you imagine seeing this in our night sky? It'd be terrifying! Image via NASA.

This diagram depicts our solar system ( obviously NOT to scale ) as our very nearby star aka the sun, is only 93,000,000 miles away from Earth !! The sun is obviously gargantuan and 98% of our solar system material is in the spherical ball of nuclear fusion that is our power source for life on Earth !! This solar system as visited by voyager 1 & 2 respectively

Voyager 1 spacecraft's biggest moments are shown in this chart covering the last 36 years. Voyager 1 is almost 12 billion miles away now! and moving at miles per hour!Voyager 1 will be the first ever object we've sent outside our solar system.

Jupiter is the fifth planet from the Sun and is the largest planet in the solar system, like the other four outer planets Jupiter is a gas giant.

The bright light in the lower right of the sun shows an X-class solar flare on Oct. as captured by NASA's SDO. This was the third X-class flare in 48 hours, which erupted from the largest active region seen on the sun in 24 years.
