University of Tennessee researchers have discovered that North America’s prehistoric art depicts a complex religious and cosmological belief system:

It is likely some of the most widespread and oldest art in the United States. Pieces of rock art dot the Appalachian Mountains, and research by University of Tennessee, Knoxville, anthropology professor Jan Simek finds each engraving or drawing is strategically placed to reveal a cosmological puzzle.

Recently, the discoveries of prehistoric rock art have become more common. With these discoveries comes a single giant one—all these drawing and engravings map the prehistoric peoples’ cosmological world.

The research led by Simek, president emeritus of the UT system and a distinguished professor of science, is published in this month’s edition of the journal Antiquity. The paper is co-authored by Nick Herrmann of Mississippi State University, Alan Cressler of the U.S.

Heat Wave Due To “Exceptionally Strong” Air Mass

Today has been the coolest day all week in the Northeast of the US.  The Midwest, Northeast and Southern parts of the country have been experiencing consecutive days of high temperatures and humidity which have contributed to many deaths throughout the country. What is the cause of this cantankerous heat and is it an indication of future affects of global warming? The National Geographic reports:

A stubborn high-pressure system is the culprit behind the dangerously high heat wave that’s been baking much of the U.S., experts say.

The high-pressure system—a large area of dense air—is being held in place by upper-level winds known as the jet stream. Within the system, dense air sinks and becomes warmer, and since warm air can hold more moisture than cooler air, there’s also very high humidity. (Learn more about Earth’s atmosphere.)

Stationary high-pressure systems aren’t unusual during the summer, according to Eli Jacks, a meteorologist at the National Weather Service headquarters in Silver Spring, Maryland.

Two suns were seen setting in the China sky. Videos of the sight have baffled scientists  after an earlier report was ridiculed warning of a nearby star explosion that would appear to be another sun. Could there really be another sun-like star or is it just an optical illusion? Via Mother Nature Network:

Weeks after a story shot across the Web claiming that the imminent explosion of a nearby star would result in the appearance of a second sun in the sky – a story that was later debunked – two suns were caught on camera yesterday in China. The suns – one fuzzy and orange, the other a crisp yellow orb – appeared side-by-side, one slightly higher than the other.

What’s going on? Life’s Little Mysteries, a sister site to Space.com, asked Jim Kaler, the University of Illinois astronomer who squelched the excitement over the aforementioned exploding Betelgeuse and who has written books on the day and night sky.
