Commencing in 1973, several spacecraft done planetary flyby manoeuvres that brought them throughout the observation array of Jupiter. The Pioneer missions received the very first near-up pictures of Jupiter's atmosphere and several of its moons. They found out that the radiation fields near the Earth were being A great deal more robust than anticipated, but both spacecraft managed to survive in that ecosystem.
Nonetheless, Saturn migrated inward likewise and became locked in an orbital resonance with Jupiter. The fuel all around Jupiter and Saturn was cleared out, and under the affect with the orbital resonance, Jupiter and Saturn migrated outward to their existing-working day positions. (The grand tack speculation is named for this inward and then outward migration wherein Jupiter modifications Instructions just like a sailboat tacking to the h2o.) This hypothesis also clarifies several other very long-standing puzzles about the photo voltaic technique, like the tiny sizing of Mars and why the asteroid belt has both equally rocky and icy asteroids.

The Jupiter spouse and children is outlined as comets which have a semi-main axis smaller than Jupiter's; most limited-period comets belong to this team. Customers from the Jupiter family members are thought to kind within the Kuiper belt outside the house the orbit of Neptune.
海中での生活に適応しているにもかかわらず、スキューバダイビングをしている人間と同じように、イルカやクジラも潜水病（減圧症）になる可能性が最新の研究で明らかにされた。 減圧症とは、水中を急浮上して水圧が急に下がると、血液や体液に溶け込んでいた気体が気泡となって、血液や臓器の中にエアポケットを形成する現象だ。発症すると筋肉や関節の痛みを生じるだけでなく、死に至ることもある。ヒト以外の潜水する動物については、減圧症の研究は進んでいない。動物の組織中で、これらの気体がどうなるのかほとんど知られていないからだ。（参考記事：「海生哺乳類が長く潜水できる理由」） 今回、米ノースカロライナ大学ウィルミントン校の研究チームは、海洋哺乳類の組織（詳しく言うと、マッコウクジラやハンドウイルカのように歯を持つハクジラ亜目が反響定位に使う顎の脂肪組織）が、減圧症の一因となる窒素ガスをどのように取り込むかを調べた。その結果、脂肪に溶け込む窒素ガスの量は脂肪の組成によって決まることと、脂肪の組成はクジラの種類ごとに異なることが明らかになった。（参考記事：「オキゴンドウ（ハクジラ亜目）の高度な反響定位能力」）
The puzzling, intriguing floor of Jupiter's icy moon Europa looms massive Within this shade view established from images taken by NASA's Galileo spacecraft from the late nineties.
で、いつか泳げるようになったらサテライトから出して水槽に放してあげたいな。

Getting just studied Earth’s moon together with his telescope, Galileo experienced noticed motion similar to this before—People “stars,” he understood, were not stars in the least but specific moons that seemed to revolve all-around Jupiter. Galileo’s discovery debunked the Ptolemaic method of astronomy, which assumed Earth as click here the center on the solar procedure with all other celestial bodies revolving around it. By observing four of Jupiter’s moons (later named Io, Europa, Ganymede, and Callisto), Galileo supplied strong evidence for that Copernican product with the solar technique, which destinations the Sunshine at the middle with the solar technique with Earth and another planets shifting about it and smaller celestial bodies like moons revolving round the planets.
