NASA’s Goddard Space Flight Center has assembled a half hour compilation of solar videos from the Solar Dynamics Observatory... by clicking on the little gear symbol under the screen, you can watch at full 2160p resolution, should your monitor be capable of handling it. If not, you can settle for 1440p, 1080p, 720p, 480p or 360p. Choose the highest resolution possible for your computer/monitor and choose to expand the screen to Theater Mode or Full Screen by clicking on the boxes at the lower right of your screen.

It’s always shining, always ablaze with light and energy that drive weather, biology and more. In addition to keeping life alive on Earth, the sun also sends out a constant flow of particles called the solar wind, and it occasionally erupts with giant clouds of solar material, called coronal mass ejections, or explosions of X-rays called solar flares. These events can rattle our space environment out to the very edges of our solar system. In space, NASA’s Solar Dynamics Observatory, or SDO, keeps an eye on our nearest star 24/7. SDO captures images of the sun in 10 different wavelengths, each of which helps highlight a different temperature of solar material. In this video, we experience SDO images of the sun in unprecedented detail. Presented in ultra-high definition, the video presents the dance of the ultra-hot material on our life-giving star in extraordinary detail, offering an intimate view of the grand forces of the solar system....

How far can solar energy go?

Big Picture, Big Ideas ...

David Attenborough: If we could catch one five-thousandth part of the energy that the Sun sprays onto the Moon, onto this globe every day, we would supply all the energy requirements of humanity. So how inefficient are we that we can't get that much?"

Attenborough is one of the public faces at the global climate summit of an initiative dubbed the Global Apollo Programme, which seeks to make renewable energy cheaper than coal within 10 years.

The goal would be achieved by convincing governments to invest US$15 billion (€14.2 billion) a year in research and development - a patch, the programme says, on the US$100 billion spent annually on defense-related R&D.

The resulting knowledge and technology should be made freely available to all. The incentive? "Only saving the world," said Attenborough.

Making renewables cheaper than energy from coal, oil and gas was the only answer, added Attenborough. "Then the nations of the world, developed or undeveloped, would choose to use that rather than carbon-derived fuel so that the coal and oil which has caused so much trouble now will stay in the ground where it's out of trouble."
