The workshop will include an interactive activity where people will determine what can and cannot be composted.

If we understood how Earth's climate has changed over its long geological history, we could better understand modern climate change. In 2020, geoscientists took a major step towards that goal when they published the most complete reconstruction of the last 66 million years of Earth's climate history.

In 2020, a team of American scientists reported the first remotely sensed evidence of the mineral hematite on Earth's moon. The researchers made their discovery with a NASA instrument aboard the Indian space agency's Chandrayaan-1 spacecraft orbiting the moon.

Many astronomers think that exoplanets circling distant stars might be waterworlds, but maybe we don't need to look that far away. In 2020 two American geologists published evidence that Earth's surface may have been entirely covered with water up until at least 3.2 billion years ago.

The surface of Venus is dotted with ring-like structures named coronae, produced by volcanic activity. They appear to be much like the Hawaiian islands on Earth, which are products of volcanic activity from a plume of hot material welling up from Earth’s mantle.

Scientists have discovered evidence of another ancient asteroid impact, but not the one that killed the dinosaurs. This asteroid is much, much older than that.

A planet has to have a magnetic field to make aurora lights. The sun is always sending out particles called the solar wind. That wind frequently increases in intensity to become a solar storm when large numbers of particles are released.

The Earth needed a number of things to become habitable. First of all, it needed to be close to a star, but not too close. It also needed water, a rocky surface and atmosphere. Most important of all, however, it needed a magnetic field.

Probability would lead us to believe that extraterrestrial life does exist, so why have we not found any?

It's amazing how much light our moon reflects. Having a few mirrors doesn't hurt, though. They're there because of the Lunar Laser Ranging experiment.
