Mercury May Have Harbored an Ancient Magma Ocean--    By analyzing Mercury’s rocky surface, scientists have been able to partially reconstruct the planet’s history over billions of years. Now, drawing upon the chemical composition of rock features on the planet’s surface, scientists at MIT have proposed that Mercury may have harbored a large, roiling ocean of magma very early in its history, shortly after its formation about 4.5 billion years ago.

Scientists have found that, on average, Mercury spins on its axis 9 seconds faster than had previously been anticipated.

Frozen Water and Organic Material Discovered on Mercury's north pole

Frozen Water and Organic Material Discovered on Mercury

Frozen Water and Organic Material Discovered on Mercury-For the first time, scientists have confirmed that the planet Mercury holds water ice and organic material in permanently shadowed craters at its North Pole.

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。

Behold an expanding shell of debris called SNR 0519-69.0, left behind after a massive star exploded in the Large Magellanic Cloud: “Multimillion degree gas is seen in X-rays from Chandra, in blue. The outer edge of the explosion (red) and stars in the field of view are seen in visible light from the Hubble Space Telescope.”(NASA/Chandra X-Ray Observatory)  Source: Humanoid History
