Mini Milky Ways Pack a Big Punch

Astronomers looking at galaxies in the universe’s distant past found nine young, compact galaxies, each weighing in at 200 billion times the mass of our Sun. Each compact galaxy is only 5000 light years across which is a fraction of our own grown up Milky Way but contains roughly the same number of stars.

A planet in a compact galaxy would see 200 times more stars in the sky than you do from Earth. Get the full story from HubbleSite.org.

Made in Mexico: Domesticated Sunflowers

Sunflower

New evidence confirms that the sunflower was domesticated in Mexico more than 4,600 years ago, contrary to the widely held belief that it was converted into a food crop only in the Mississippi Valley. Researchers use to believe Spanish conquistadors were responsible for bringing domesticated sunflowers to Mexico from the north. But genetic research on ancient seeds found at formerly inhabited sites indicate that indigenous people in different parts of Mexico were using sunflowers 1800 years before being conquered by the Spaniards.

LA Times has the story.

Nat. Geographic: Next Decade Will Be Cooler

Global Warming

Cooler climate may hit N.America and Europe Next Decade

If National Geographic prints it, it must be gospel.

A new forecasting model, based on past and present sea surface temperatures, suggests the imminent onset of a cool-down cycle for currents in both the North Atlantic and tropical Pacific.

Of course, it could turn out to be temporary with following decades getting warmer, but it’ll be hard to train people to prepare for heat tomorrow when it’s cool today.

The Holy Nanochip
