SN 2006gy

Brightest Supernova May Reignite

 

New supernova mechanism would set off repeat explosions.

A new type of ultra powerful supernova discovered last year may blow its top again, according to a new study. Researchers report that supernova 2006gy fits a model of star explosion that should have produced two flare-ups already and may culminate in a third before the star fizzles out. 

A second study proposes that the explosion might have come about from the marriage of multiple stars.

 

SN 2006gy first caught astronomers' eyes in September. Burning 100 times brighter than a typical supernova, it maintained full strength for an amazing three months, by which point most of its counterparts would have begun fading.

20 Things You Didn’t Know About... Gold

Anti-inflammatory, protector of astronaut eyes, and excrement of the gods. 

1  Gold was probably the first metal worked by prehistoric man. Decorative gold objects found in Bulgaria date back to 4,000 B.C., so the gold age actually overlaps with the Stone Age.

2  In the 7th century B.C., dentists in Italy used gold wire to attach fake teeth, and gold fillings were recommended for cavities as far back as the 16th century.

3  When the Spaniards landed in Peru in 1532, the Incan Empire had one of the largest collections of gold ever amassed. After the Incan king Atahuallpa was captured by the conquistadores, he offered, as ransom, to fill a 22-by-18-foot room with gold as high as he could reach.

4  The Spanish killed him anyway.

5  The Aztec word for gold is teocuitlatl, which means “excrement of the gods.”

Conrad Reed found a 17-pound lump of gold on his father’s North Carolina farm in 1799, the first documented discovery of gold in the United States. They used the rock as a doorstop for three years before a local jeweler identified it.

7  Reed’s father sold it to the jeweler for $3.50, less than one-thousandth of its true value. Eventually Reed caught on—the lump would be worth more than $100,000 today—and started the nation’s first commercial gold mine.

Innovation of the year

Nanosolar Powersheet - The New Dawn of Solar

 

Imagine a solar panel without the panel. Just a coating, thin as a layer of paint, that takes light and converts it to electricity.

 

From there, you can picture roof shingles with solar cells built inside and window coatings that seem to suck power from the air. Consider solar-powered buildings stretching not just across sunny Southern California, but through China and India and Kenya as well, because even in those countries, going solar will be cheaper than burning coal.

 

That’s the promise of thin-film solar cells: solar power that’s ubiquitous because it’s cheap. The basic technology has been around for decades, but this year, Silicon Valley–based Nanosolar created the manufacturing technology that could make that promise a reality.

The company produces its PowerSheet solar cells with printing-press-style machines that set down a layer of solar-absorbing nano-ink onto metal sheets as thin as aluminum foil, so the panels can be made for about a tenth of what current panels cost and at a rate of several hundred feet per minute.

 

With backing from Google’s founders and $20 million from the U.S. Department of Energy, Nanosolar’s first commercial cells rolled off the presses this year.

“You see things; and you say, 'Why?' But I dream things that never were;

What if…

Remember when we were all imagining how we would remake KONG? Since I always had a fetish for tall girls I came up with this idea. Unfortunately it was denied by the studio... I believe a naked girl on top of the building is much better then a fucking gorilla!
