A blue moon. World Space Week begins

Today, we're blasting off to explore the cosmos. World Space Week celebrates the science and technology that go into exploring our universe, and how it benefits us back on Earth. Space exploration has helped scientists develop new medicines, create new power sources, and even improve farming techniques. This year's theme is Space and Climate Change; events will be held in 83 countries to champion the role of space technology in understanding and monitoring Earth's climate.

Space exploration has also led to amazing photographs of our solar system, like the one featured here today. Europa is one of Jupiter's 95 known moons. Its surface is mainly made up of frozen water, which has broken up and refrozen, creating the patterns seen on its surface. Although Europa is just a quarter of the size of Earth, it may contain twice the amount of water. Space Week is the perfect time to take a moment to appreciate the wonders of our solar system, and beyond!
