Space Music: How To Hear Solar Flares From The Moon

Originally published on Thu January 9, 2014 6:04 pm

Live, from the moon, it's the space weather report: Data from a lunar orbiter is being used to create a music stream that reflects conditions in space. Here, an image created by NASA "visualizers" who used data from 2010 to show the moon traveling across the sun, as happens two or three times a year.

We've been following the coronal mass ejection that headed toward Earth after an intense solar flare was emitted from the sun earlier this week. And now NASA tells us that such events can be heard, in a sense, by tuning in to CRaTER Radio, a "sonification" project that uses data from NASA's Lunar Reconnaissance Orbiter to generate musical sounds and stream them on the Internet.

We've survived the stretch between Thanksgiving and New Year's Day, when rich, sweet treats come at us non-stop. Now is the season of reform, when gym memberships, cleanse books and weight-loss plans sell like gangbusters.

The Anthropology Of Walking

Catching up on my journal reading over Christmas break, I came across a study by an international team of anthropologists which points to a fascinating pattern in how humans move across the landscape. Whether foraging for food in Tanzania or walking from Space Mountain to the Pirates of the Caribbean ride in Disney World, we tend to adopt what's called a Lévy walk, a type of random walk where groups of short step lengths are interspersed with longer movements.

Update at 3:05 p.m. ET:

NOAA's Space Weather Prediction Center now reports:

"The coronal mass ejection (CME), originally expected to arrive around 0800 UTC (3:00 a.m. EST) today, January 9, was observed at the ACE spacecraft just upstream of Earth at 1932 UTC (2:32 p.m. EST)."

The SWPC goes on to say that "the original forecast continues to be for G3 (Strong) Geomagnetic Storm activity on January 9 and 10."

"Aurora watchers may be in luck for tonight."

If you think buying health insurance under the Affordable Care Act has been complicated, just wait. Buying dental coverage on the health exchanges, it turns out, is even more confusing.

Dental coverage for children is one of the benefits that must be offered under the law. But, it turns out, a loophole in the law means that — in most states — families don't actually have to buy that coverage.

These rules are so confusing that they even tripped me up.

A new study of volcanic rocks suggests that an ancient mural may indeed depict an erupting volcano, adding new weight to a theory that this image is a contender for the world's oldest known landscape painting or map.

Solar Flare Will Hit Earth Thursday; Northern Lights May Expand South

Coming At You: An image created by NASA combines two pictures from its Solar Dynamics Observatory. One shows the location of a large sunspot; the other shows Tuesday's massive solar flare.

Tired of reading about intensely cold temperatures? Here's some news that might help take your mind off this week's deep freeze. It could even give you an excuse to hang around outside Thursday.

An intense solar flare is being blamed for disrupting a NASA mission and could force airlines to reroute some flights. That's the bad news. The good news is that the flare is also expected to expand the viewing field of the aurora borealis southward, perhaps down to Colorado and Illinois.
