Astronaut Anton Shkaplerov captured this shot of Tortuga Island in the Galapagos from the International Space Station earlier this month. The name “Tortuga” is given to a number of islands and features such as bays around the world – it translates to “Turtle” and is given to this island because of the tortoises that lived on it. The island is obviously an old, eroding volcanic crater. It is considered a “Tuff ring”, made mostly of palagonite, an altered igneous rock formed when molten rock interacts with water and explodes. Molten rock rose up in the center of this feature, interacted with seawater, and triggered explosions that threw material outwards, forming the tuff ring.

The largest and most powerful hurricanes ever recorded on Earth spanned over 1,000 miles across with winds gusting up to around 200 mph. That’s wide enough to stretch across nearly all U.S. states east of Texas. But even that kind of storm is dwarfed by the Great Red Spot, a gigantic storm in Jupiter. There, gigantic means twice as wide as Earth.

With tumultuous winds peaking at about 400 mph, the Great Red Spot has been swirling wildly over Jupiter’s skies for the past 150 years—maybe even much longer than that. While people saw a big spot in Jupiter as early as they started stargazing through telescopes in the 1600s, it is still unclear whether they were looking at a different storm. Today, scientists know the Great Red Spot is there and it’s been there for a while, but they still struggle to learn what causes its swirl of reddish hues.
