KPCC vs. The Sun: Solar flares, cosmic rays, and a chat with the director of the Griffith Observatory

An angry sun is a vengeful sun, and based on the attention given to the solar flare that stormed Earth today, we wondered if somehow we'd upset the giant Lite-Brite in the sky.

Of course not, says longtime director of the Griffith Observatory, Dr. Edwin Krupp. This has been going on for a while, he said, noting that the sun has been around about four and half billion years. Solar activity, he explained, runs in 11 year cycles (solar activity is expected to peak in the current cycle around 2013), and people have been counting the spots on the sun for thousands of years.

The solar telescope at Griffith Observatory has been tracking the activity, Dr. Krupp told KPCC, but as far as viewing goes, this particular group has slipped to the side because of the rotation of the sun.

We asked Dr. Krupp if the museum's cloud and spark chambers — two on-site instruments measuring the bombardment of Earth by cosmic rays — would be seeing an increase in activity following an event like this.

Modern rock: The one about the frenzy over LACMA's big piece of granite

One day, when aliens find our historical records and attempt to piece together the final days of human society, they will believe, with unshakable conviction, that we were a people who worshipped a giant, granite boulder.

From quarry to museum, this is the story of what happened when Greater Los Angeles followed a 340-ton pet rock on the world's slowest road trip. [MAP]

Here is a roundup of rockin' puns and questionable coverage...

NASA and JPL's holy 'GRAIL' of moon research

GRAIL Mission Comes Together: NASA's twin Gravity Recovery and Interior Laboratory (GRAIL) spacecraft are lowered onto the second stage of their Delta II launch vehicle at Space Launch Complex 17B at Cape Canaveral Air Force Station in Florida (8/18/2011). At the top of the image is the spacecraft adapter ring which holds the two lunar probes in their side-by-side launch configuration. The adapater ring and the probes are wrapped in plastic to prevent contamination outside the clean room in the Astrotech Space Operation's payload processing facility in Titusville, Fla. The spacecraft will fly in tandem orbits around the moon for several months to measure its gravity field. GRAIL's primary science objectives are to determine the structure of the lunar interior, from crust to core, and to advance understanding of the thermal evolution of the moon.

The fairing will protect the spacecraft from the impact of aerodynamic pressure and heating during ascent and will be jettisoned once the spacecraft is outside the Earth's atmosphere.

GRAIL Flying in Formation (Artist's Concept): Using a precision formation-flying technique, the twin GRAIL spacecraft will map the moon's gravity field. The mission also will answer longstanding questions about Earth's moon, including the size of a possible inner core, and it should provide scientists with a better understanding of how Earth and other rocky planets in the solar system formed.

Along with its twin GRAIL-B, the GRAIL-A spacecraft underwent an 11-day-long test at Lockheed Martin Space Systems in Denver that simulated many of the flight activities they will perform during the mission, all while being exposed to the vacuum and extreme hot and cold that simulate space.

GRAIL's Twin Spacecraft fly in Tandem Around the Moon (Artist's Concept): The Gravity Recovery and Interior Laboratory (GRAIL) mission utilizes the technique of twin spacecraft flying in formation with a known altitude above the lunar surface and known separation distance to investigate the gravity field of the moon in unprecedented detail. The technique utilizes radio links between the two spacecraft as well as radio links to stations on Earth. The mission also will answer longstanding questions about Earth's moon, including a possible inner core, and provide scientists with a better understanding of how Earth and other rocky planets in the solar system formed.

Twin NASA probes began studying the moon's gravity late Tuesday night in effort to determine why the moon, Earth's only natural satellite, is shaped the way it is.

Managed locally at NASA's Pasadena-based Jet Propulsion Laboratory, the three-month GRAIL mission (Gravity Recovery And Interior Laboratory), will begin analyzing data in one month.

Scientists want to know why the Pink Floyd side of the moon appears to be more mountainous than the side that always faces Earth. Despite numerous missions, they still don't have that answer.

Additionally, by mapping the lunar gravity field, investigators hope to support or discredit a theory that Earth at one time had two moons.

Researchers hope the $496 million mission -- which includes spacecraft development, science instruments, launch services, mission operations, science processing and relay support -- will net significant intel about what lies below the surface.

Mayor Antonio Villaraigosa backs gay marriage plank for Dems (video)

The chairman of the 2012 Democratic National Convention, L.A. Mayor Antonio Villaraigosa, said during a Politico function on Wednesday that he supports the gay marriage legalization plank in his party’s platform.

“I think it’s basic to who we are,” Villaraigosa said of the issue he has long supported. “I believe in family values and I believe that we all ought to be able to have a family and marry if you want to. I don’t think the government should be in that business of denying people the fundamental right to marry.”

Villaraigosa also criticized the GOP for wading into social issues.  

"The Republicans have gotten so far out of the mainstream," according to the mayor. "I mean, at a time when all of us should be focused on the economy, they’re focused on contraception and mammograms."

A fire that broke out Monday night at a legendary recording studio in Hollywood is being investigated by authorities.

The blaze began around 7 p.m. at 1041 Production Studios, and was extinguished in approximately 10-20 minutes, according to LAFD officials.

The studio, built in 1929 by the Victor Talking Machine Co., is believed to be one of the oldest of its kind in Hollywood, according to LA Observed

Known at one time as Radio Recorders, the facility was reportedly used by major labels to record an exhaustive list of artists including Elvis Presley, Nat King Cole, the Beach Boys, and others.

No human injuries were reported in the ordeal. KTLA reported that a cat, unconscious from smoke inhalation, was rescued and revived by firefighters.

The second floor reportedly suffered extensive damaged and a partial roof cave-in. The cause of the fire was not immediately known.
