What is OPAL?



OPAL (Outer Planet Atmospheres Legacy) is a project to obtain long time baseline observations of the outer planets in order to understand their atmospheric dynamics and evolution as...

The number of sunspots increases and decreases over time in a regular, approximately 11-year cycle, called the sunspot cycle. The exact length of the cycle can vary. It has been as short as eight years and as long as fourteen, but the...

If any of these energy bombs hit Earth, humanity’s satellites, internet and electrical systems will fry and burn out.

A comet's journey through the solar system is perilous and violent. Before it reaches Mars - at some 230 million miles away from the sun - the radiation of the sun begins to cook off the frozen water ice directly into gas. This...

An animated explanation of how eclipses work. As you know a solar eclipse occurs when the moon is placed between the earth and the sun. But, if the moon takes about 28 days to travel around Earth, why don’t we see eclipses every month?

Solar and lunar eclipse - which is which? And how can you finally remember the difference?

The Solar and Heliospheric Observatory, a joint mission between ESA (the European Space Agency) and NASA, was not designed to find comets — its original goal was to study the Sun from its deep core to the outer layers...

What is a black hole? How is it formed? And where are they? In this video, learn from Space Science specialist Douglas Equils about one of the most massive and mysterious things in our universe, black holes. From the GCSE / K12 "Earth...

Satellite footage, telescopic photos and animation are used to teach students about the many fascinating aspects of our solar system. Viewers are introduced to ancient astronomers, telescopes, observatories and space exploration....

Solar winds are super fast, nuclear winds emitted by the sun. Were these winds to reach Earth's surface, they would cause a lot of damage. Find out what makes solar winds so dangerous andwWhat protects Earth from this weather.

Through telescopic video and photos combined with animated graphics, students will learn about the layers of the sun and its effects on earth, the moon and all the objects in our solar system and the universe.

On Halloween in 2003, the sun unleashed a series of spooky storms, which ignited lots of ghostly looking auroras, and effected power grids, satellites and other electrical equipment. On the fifth anniversary, NASA takes a look back at...

The atmosphere is dynamic and forever changing to maintain balance. The ingredients of air, sunlight and water allow life to exist on Earth, but they also generate calm scenes like rainbows, as a tornado ends. All storms move moisture,...
