Climate change is a looming threat to planet Earth, so scientists have been thinking of solutions. One of them is going to Mars in case Earth becomes inhabitable, as scientists think there might be water on Mars. But if someone asked me if I would move to Mars, I would always come out with a straight answer: no.

The 1980 Mount St Helens eruption in the USA led to a surprising discovery. The eruption killed 57 people and destroyed 350 km2 of forest. In an effort to restore the ecosystem of the plains, in 1983, scientists captured 2 wild gophers, placing each into a small, fenced off area on the volcanic plain. The gophers dug for twenty-four hours before the scientists removed them. A new study published in 2024 shows the long-lasting effects the gophers had on the ecosystem.

When astronomers first looked at the Moon through telescopes, they thought they were seeing great oceans. They gave the Moon’s big, dark patches names such as Oceanus Procellarum, and the Sea of Tranquillity. Now we know that these ‘seas’ are ancient lava flows, and that the Moon’s surface is very dry. It’s also airless.
