Full HD (1920 x 1080 pixels at 30 fps) movie mode plus HDMI output for easy playback of video and photos on your HDTV.

The first PowerShot camera to feature a 10.0 Megapixel Canon CMOS sensor for superb image quality.

28mm wide-angle 20x Optical Zoom lens with Optical Image Stabilizer.

Large 2.8-inch Vari-angle LCD widescreen for flexible viewing at nearly every angle, plus a viewfinder for more shooting options.

Full range of shooting and recording modes including RAW + JPEG for the ultimate creative control.

DIGIC 4 Image Processor has evolved Face Detection Technology that tracks the faces of moving subjects and lets the shooter enter the frame seamlessly with the Face Detection Self-timer.

With 25 Shooting Modes including 12 Special Scene Modes, you’re ready for whatever shot comes your way.

Create Full HD Movies with Your Camera.
Full HD (1920 x 1080 pixels at 30 fps) movie mode plus HDMI output for easy playback of video and photos on your HDTV.

If you long for the convenience of an advanced still camera that also creates superb movies, the new PowerShot SX1 IS was developed with you in mind. Movies shot in Full HD (1920 x 1080 pixels), capture your memories with all the clarity, realism and brilliance. The PowerShot SX1 IS also makes it easy to enjoy HD movies and photos on your HDTV with a mini-HDMI cable for direct connection to a high-definition monitor. This allows you to enjoy the full quality of HD with no degradation of image or audio in the signal, but also improves playback functionality, letting you view up to 130 still images at once.

September 22, 2012 Catastrophe

According to newscientist.com it is midnight on September 22, 2012 and the skies above Manhattan are filled with a flickering curtain of colorful light. Few New Yorkers have seen the aurora this far south but their fascination is short-lived. Within a few seconds, electric bulbs dim and flicker, then become unusually bright for a fleeting moment. Then all the lights in the state go out. Within 90 seconds, the entire eastern half of the US is without power.

A year later and millions of Americans are dead and the nation’s infrastructure lies in tatters. The World Bank declares America a developing nation. Europe, Scandinavia, China and Japan are also struggling to recover from the same fateful event – a violent storm, 150 million kilometers away on the surface of the sun.

It sounds ridiculous. Surely the sun couldn’t create so profound a disaster on Earth. Yet an extraordinary report funded by NASA and issued by the US National Academy of Sciences (NAS) in January this year claims it could do just that.

Over the last few decades, western civilizations have busily sown the seeds of their own destruction. Our modern way of life, with its reliance on technology, has unwittingly exposed us to an extraordinary danger: plasma balls spewed from the surface of the sun could wipe out our power grids, with catastrophic consequences.

The projections of just how catastrophic make chilling reading. “We’re moving closer and closer to the edge of a possible disaster,” says Daniel Baker, a space weather expert based at the University of Colorado in Boulder, and chair of the NAS committee responsible for the report.

It is hard to conceive of the sun wiping out a large amount of our hard-earned progress. Nevertheless, it is possible. The surface of the sun is a roiling mass of plasma – charged high-energy particles – some of which escape the surface and travel through space as the solar wind. From time to time, that wind carries a billion-tonne glob of plasma, a fireball known as a coronal mass ejection. If one should hit the Earth’s magnetic shield, the result could be truly devastating.

The incursion of the plasma into our atmosphere causes rapid changes in the configuration of Earth’s magnetic field which, in turn, induce currents in the long wires of the power grids. The grids were not built to handle this sort of direct current electricity. The greatest danger is at the step-up and step-down transformers used to convert power from its transport voltage to domestically useful voltage. The increased DC current creates strong magnetic fields that saturate a transformer’s magnetic core. The result is runaway current in the transformer’s copper wiring, which rapidly heats up and melts. This is exactly what happened in the Canadian province of Quebec in March 1989, and six million people spent 9 hours without electricity. But things could get much, much worse than that.

Inside the Mysterious Tunnel in the Tomb of Seti I

Many people make the mistake of thinking that dreams cannot come true, but they can. You have to believe, and know that they are more than just imagination.

— Zahi Hawass

For the last two years, Zahi Hawass has led an all-Egyptian team that is excavating and restoring the mysterious tunnel leading from the burial chamber of King Seti I deep into the Theban cliffs. No explorer has ever reached its end. The reason for the tunnel’s existence is unknown, but Hawass is determined to uncover its mysteries.

Zahi Hawass takes viewers deep into the mysterious tunnel that leads from the burial chamber of Seti I. He discusses his team’s work to excavate and restore the tunnel, and their hope of solving the mystery of what may lie at its end.
