Cosmos Magazine has partnered with Double Helix to publish a free eBook that takes kids aged 8 to 12 on a dive into the science of our oceans. The eBook includes stories about turtles, wonky holes and undersea cables, as well as experiments to do at home.

CSIRO scientists have found a species of fish to add to Australian aquaculture and, hopefully, Aussie diets. Trachinotus anak, known as the pompano, oyster pompano, giant oystercracker or dart, is a white-flesh fish endemic to northern Australia, and CSIRO’s top choice for farming.

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.

A famous person built a square house so that the windows on all four sides look south. Where is this house? (And can you name the famous person?)

Twinkle, twinkle, giant stars! Pairs of so-called ‘heartbeat’ stars change their brightness like the rhythm of a beating heart. For the first time, new models show that they also create gigantic waves.

Space is huge. But exactly how huge are the spaces between the Sun, Moon and planets? Find out by making a scale model of the inner solar system at your nearby park!

With this quiz, everything is looking up! Can you dazzle us with a stellar 5/5?

If good things come to those that wait…then these bold oldies are gold! Do you have the patience and wisdom to top this quiz or will you need to wait for the next one?

What caused the dinosaurs to go extinct 66 million years ago? Most scientists think an asteroid impact sealed their fate. But others think massive volcanic eruptions in India did the job. Now, scientists from Europe have used chemistry to support the asteroid theory and they can even say where the asteroid came from!
