Monster Supernovae May Explain Galaxy's Mystery Haze

The mysterious WMAP haze (Image: WMAP)

From New Scientist:

WHAT is causing a mysterious "haze" of radiation at the centre of the Milky Way? It may be a load of monster supernovae kicking out radiation which is then amplified by magnetic stellar winds and turbulence near the galaxy's core.

In 2003, the Wilkinson Microwave Anisotropy Probe found a patch of particularly energetic microwave radiation in the centre of our galaxy - dubbed the "WMAP haze". It was proposed that this could be caused by collisions of a new type of dark-matter particle.

Why 'Sleeping On It' Helps

From Live Science:

We're often told, "You should sleep on it" before you make an important decision. Why is that? How does "sleeping on it" help your decision-making process?

Conventional wisdom suggests that by "sleeping on it," we clear our minds and relieve ourselves of the immediacy (and accompanying stress) of making a decision. Sleep also helps organize our memories, process the information of the day, and solve problems. Such wisdom also suggests that conscious deliberation helps decision making in general. But new research (Dijksterhuis et al., 2009) suggests something else might also be at work — our unconscious.

Awesome Pictures Of Saturn

From 20 degrees above the ring plane, Cassini's wide angle camera shot 75 exposures in succession for this mosaic showing Saturn, its rings, and a few of its moons a day and a half after exact Saturn equinox, when the sun's disk was exactly overhead at the planet's equator. The images were taken on Aug. 12, 2009, at a distance of approximately 847,000 km (526,000 mi) from Saturn. (NASA/JPL/Space Science Institute)

Saturn At Equinox -- Boston.com

Checking in with NASA's Cassini spacecraft, our current emissary to Saturn, some 1.5 billion kilometers (932 million miles) distant from Earth, we find it recently gathering images of the Saturnian system at equinox. During the equinox, the sunlight casts long shadows across Saturn's rings, highlighting previously known phenomena and revealing a few never-before seen images. Cassini continues to orbit Saturn, part of its extended Equinox Mission, funded through through September 2010. A proposal for a further extension is under consideration, one that would keep Cassini in orbit until 2017, ending with a spectacular series of orbits inside the rings followed by a suicide plunge into Saturn on Sept. 15, 2017.

Comets Didn't Wipe Out Sabertooths, Early Americans?

North America's Great Lakes (pictured in an aerial shot on May 4, 2002) were created during glacial retreats and advances over millions of years—including the brief cold snap called the Younger Dryas, which occurred about 12,900 years ago.

From Time Magazine:

Earthquakes have always been part of Los Angeles' past — and its future. In 1994 a 6.7-magnitude quake hit the Northridge area of the city, badly damaging freeways, killing more than 70 people and causing $20 billion in damages. But those numbers could be dwarfed by a major quake in the future. The geologic record indicates that huge quakes occur roughly every 150 years in the region — Los Angeles lies along the southern end of the San Andreas Fault — and the last big quake, which registered a magnitude 7.9, happened in 1857. Los Angeles has done a lot to beef up its building codes and emergency response in the 15 years since the Northridge quake and may be better prepared than any other major American city, but the city's sheer size ensures the next Big One will be bloody.

Spencer: AGW Has Most Of The Characteristics Of An “Urban Legend”

Urban legend? Gators don't really live in the sewer.

From Watts Up With That?

About.com describes an “urban legend” as an apocryphal (of questionable authenticity), secondhand story, told as true and just plausible enough to be believed, about some horrific…series of events….it’s likely to be framed as a cautionary tale. Whether factual or not, an urban legend is meant to be believed. In lieu of evidence, however, the teller of an urban legend is apt to rely on skillful storytelling and reference to putatively trustworthy sources.

I contend that the belief in human-caused global warming as a dangerous event, either now or in the future, has most of the characteristics of an urban legend. Like other urban legends, it is based upon an element of truth. Carbon dioxide is a greenhouse gas whose concentration in the atmosphere is increasing, and since greenhouse gases warm the lower atmosphere, more CO2 can be expected, at least theoretically, to result in some level of warming.

NASA Ares Rocket Development To Take Too Long

From Future Pundit:

An article in New Scientist about the NASA Ares rocket program reports that a White House advisory panel chaired by former Lockheed Martin CEO Norman Augustine recommends against further development of the Ares rocket because it will take too long to develop.

The rocket is set to make its first test flight on 27 October. But the committee believes the rocket will not be ready to loft crew to orbit until 2017, two years after the ISS is scheduled to be abandoned and hurled into the Pacific Ocean, Augustine said. Extending use of the space station to 2020 would not make much difference, since this would eat up funds available for Ares I and delay its first flight to 2018 or 2019, added committee member Edward Crawley of MIT.
