A Quote by Seth Shostak

Despite tantalizing suggestions of fossilized microbes in meteorites, puzzling and possibly biogenic methane gas in the martian atmosphere, and a long-standing controversy over the Viking lander experiments of nearly 40 years ago, there's still no Exhibit A that points unequivocally to biology in our own back yard.

When you frack a well, you're exploding methane up into the atmosphere. So, Barack Obama, by supporting natural gas, and also talking about climate change is literally burning his own inaugural address. And he's doing it with natural gas.

Josh Fox

Natural gas emits only half the carbon dioxide of coal when burned, but if methane leaks when oil companies extract it from the ground in a sloppy manner - methane is far more potent a greenhouse gas than carbon dioxide - it can wipe out all the advantages of natural gas over coal.

Thomas Friedman

But one of the coolest things about meteorites is that most were formed four-and-a-half-billion years ago, during the birth of our solar system, when, for reasons not yet known, a cloud of gas and dust was transformed into a sun with circling planets.

Neil deGrasse Tyson

The concentration of atmospheric carbon dioxide has changed greatly since fossilized life began on Earth nearly 600 million years ago. In fact, there is only 1/19 as much CO2 in the air today as there was 520 million years ago. That high CO2 was hardly the recipe for disaster.

Greg Benson

Burning carbon-based substances like oil, gas, and especially coal, produces billions of tons of extra carbon dioxide each year. Methane gas from cows and pigs and other animals on our large farms ends up in the atmosphere as well, trapping more of the sun's energy as heat.

Bill Nye

Soils could also be giving up their carbon stores: evidence emerged in 2005 that a vast expanse of western Siberia was undergoing an unprecedented thaw. The region, the largest frozen peat bog in the world, had begun to melt for the first time since it formed 11,000 years ago. Scientists believe the bog could begin to release billions of tonnes of methane locked up in the soils, a greenhouse gas 20 times more potent than carbon dioxide. The World Meteorological Organisation recently reported the largest annual rise of methane levels in the atmosphere for a decade.

David Adam

When I was a grad student at MIT, I had a chance to become friends with the Viking Mission's chief scientist, Dr. Gerald Soffen. Viking was the first Mars lander looking for signs of life on Mars.

Peter Diamandis

Our bodies are the subject of many experiments, but these experiments on the space station sometimes take years because in order for a scientist to get 10 data points, that can take six or seven years.

Anne McClain

I long ago tired of politicians who never say anything, adhere to their talking points, and avoid all controversy.

Richard Cohen

I don't think that you can possibly embrace the kind of joy which one who has worked with plants and plant structures such as I have over a period of nearly 40 years, how wonderful the plant laboratory seems.

Percy Julian

Of course methane is a fossil fuel, but as long as it is burned efficiently and fugitive emissions of methane gas are minimised, it is a less harmful fossil fuel than coal and oil and is an important way-station on the global journey towards low-carbon energy.

Mark Walport

The Martian atmosphere is very thin. It's like our atmosphere at 100,000 feet.

John M. Grunsfeld

I sensed that Confucius is an interesting character. This is someone who lived over 2,500 years ago and is still speaking to us. That people are still reading and repeating what he said so long ago is something I find quite fascinating.

Russell Freedman

Of course this is Vegas and it is the melting pot for all over the world, but people from all over the world know Donny and Marie. It is amazing. I have been in the business a long time to realize careers can be fleeting. Five years is a long career nowadays for some people, and here we are still going strong after 40 years.

Donny Osmond

For a long, long time, nearly 40 years, I never had any bees. I can't think why.

Sue Hubbell

We do have a big kind of history in literate tradition of Vikings and we have a lot of Viking blood in Scotland, I mean especially up north wherever you go you see a plastic Viking sitting outside a shop and Viking calendars and - because they - you know they came down and stole all our chicks and then some of them didn't quite get back and ended up settling down here. So there's a lot of Viking blood in Scotland.

Craig Ferguson
