Earth 2

Gliese 581g may be the new Earth.

A team of astronomers from the University of California and the Carnegie Institute of Washington say they’ve found a planet like ours, 20 light years (120 trillion miles) from Earth, where the basic conditions for life are good.

“The chances for life on this planet are 100 percent,” Steven Vogt, a UC professor of astronomy and astrophysics says. “I have almost no doubt about it.”

The planet is three times the size of Earth, but the gravity is similar.

Dr. Elizabeth Cunningham, planetarium astronomer at the Royal Observatory in Greenwich, says the discovery is a huge deal.

“It could have liquid water on the surface,” she said. “That’s the first step to find life.”

There are hundreds of known extrasolar planets that have been discovered in the Milky Way, but this is the first that could support life.

Earthlings won’t be traveling to Gliese 581g any time soon unfortunately. Scientists say a spaceship traveling close to the speed of light would take 20 years to make this journey.

But if we did – we’d find some other things familiar. The atmosphere and gravity are similar to Earth, and if you’re from the polar regions, you’d definitely feel right at home. Scientists say the highest average temperature is about -12 degrees Celcius (10 Fahrenheit), but they point out that the planet doesn’t have a night and day – one side continually faces the star and the other side faces the darkness of space. This means one side is blazing hot and the other freezing cold.

Gliese orbits a red dwarf star called Gliese 581. Cunningham says “it’s a Goldilocks planet.”

“It’s not too hot, it’s not too cold, it’s just right” for water to form, Cunningham said.

The area is called the “Goldilocks zone.”

Other planets near Gliese 581g have been discovered, but they are not habitable and are mainly comprised of gas. Gliese 581g, however, is a rocky planet.

It was discovered using the Keck telescope in Hawaii which has been observing the star Gliese 581 for 11 years.

“Keck’s long-term observations of the wobble of nearby stars enabled the detection of this multi-planetary system,” said Mario R. Perez, Keck program scientist at NASA headquarters in Washington.

Astronomers are excited this new planet was discovered so fast and relatively close by.

“I’m surprised we found one so fast,” Cunningham said. “The implication is either we were very lucky or these planets could be relatively common.”

Gliese 581g is in the constellation of Libra. While Earth takes 365 days to orbit our star, the sun, Gliese 581g orbits its star in 37 days.

Space – The End of an Era

Yesterday 220 miles above Australia the space shuttle Discovery docked with the International Space Station for the last time… and with the recent cuts to NASA budget (and cancellation of the Constellation and Aries programs) it effectively marks the end of the US space program.

I’ll underscore that most all the advances in electronics we enjoy today (micro-chips, micro-waves, etc) responsible for the growth of communications, computing, internet, consumer convenience can be traced back to the rapid push to put a man on the moon.

While this might not be the end of the technological advancements in the US, one really has to ask is it yet another sign of the decline of the US into the pages of history.

A staggering debt, unemployment by some estimates that effects one in five American adults, skyrocketing energy costs, the end of the middle class… I simply cannot imagine anyone truly believing “the land of the free and the home of the brave” applies any longer.

BANG!

In the Summer of ’62 the US military detonated a hydrogen bomb in outer space above the Pacific Ocean as part of a project code named: Starfish Prime.

There’s a good article on NPR you can read at:

A New Hope

There have been numerous firsts in the course of human events; but my belief is that one singular event set in motion a new era for human kind.

One July 20, 1969 at 4:17  pm EDT Neil A Armstrong took one small step for man as he stepped off the ladder of the Lunar Module Eagle onto the surface of the Moon and subsequently returned to Earth with “Buzz” Aldrin and the Columbia Command Module pilot Michael Collins.

While many consider this the single greatest technological achievement of all time; I would go further to say that when humans left our tiny frail planet, stepped foot on another celestial body, and safely returned it was far more than a technological achievement, it was the event the redefined man’s destiny.

Thirty-three years ago human kind boldly went into the future.

50th Anniversary

Of humans in space that is.

Today is the 50th anniversary of  Yury Gagarin’s epic flight into space.

You can find more information on the Russian Federal Space Agency’s web site, comrade.
