UFO spotted by News10 over Sacramento

SACRAMENTO, CA - News10 often receives calls from those who spotted something unusual in the night skies. It's not nearly as common for those calls to be backed up by our own Air10.
While shooting Friday Night Football highlights over Sacramento, Air10 pilot Ed Georges and FNF correspondent Angel Cardenas spotted a strange set of lights flying over their helicopter.
"I know what aircraft lighting looks like and this was definitely something different," Georges said. "It looked almost like a scrolling message on a blimp to the naked eye. I was at 1,200 feet and it was considerably higher."

Georges said he and Cardenas manuevered the helicopter to get a better look at the lights through Air10's Power Zoom camera.

"(Angel and I) were both amazed at the odd lights and movement. I started flying toward it, but it began to fade away and disappeared to the southeast," Georges said. "Not knowing the size of the object, I couldn't determine how far away we were, but I believe it was some distance away as the image was fuzzy even through the PowerZoom camera."

Not long after their sighting, several callers phoned the News10 newsroom to report seeing the same phenomenon.

When contacted, Federal Aviation Adminstration and Sacramento International Airport spokespeople said they hadn't heard anything about the object and had no idea what the craft could be. A Travis Air Force Base representative said the base had no aircrafts that could be confused with a UFO.

Water vapor and ice paticles are spewing from Enceladus

WASHINGTON (Reuters) - Huge plumes of water vapor and ice particles are spewing from Saturn's moon Enceladus at supersonic speeds in a way that strongly suggests they come from liquid water down below the icy surface, scientists said.
The research, published in the journal Nature on Wednesday, offers new evidence that the moon may harbor an underground ocean of water, meaning conditions might exist that could support life, even if only microbial organisms.

"We think liquid water is necessary for life," Candice Hansen of NASA's Jet Propulsion Laboratory in Pasadena, California, who led the study, said in a telephone interview.
"This is more evidence that there is liquid water there. You also need energy, you need nutrients, you need organics. It looks like the pieces are there. Whether or not there's actually life, of course, we can't say," Hansen said.
The Cassini spacecraft in 2005 discovered humongous geysers erupting from fissures near the south pole of Enceladus into space -- reminiscent of the famed Old Faithful at Yellowstone National Park in the United States but on a grand scale.
Since then, scientists have debated whether this meant that Enceladus (pronounced en-SELL-ah-dus), with a diameter of only 310 miles, was hiding a reservoir of liquid water. It is one of about 60 moons of the dramatic ringed planet Saturn.
Based on data collected last year by Cassini's Ultraviolet Imaging Spectrograph instrument, the researchers said the behavior of the plumes supports a mathematical model in which the cracks that extend below the surface act as nozzles that channel water vapor from an underground liquid water reservoir.
The geysers continuously shoot plumes into space at more than 1,300 mph, the researchers said.
By using the instrument to observe the flickering light of a distant star as the geyser blocked its starlight, the researchers determined that the water vapor comes from narrow jets as it blasts into space.
"We're saying we detected these jets within the plumes and the gas moving at supersonic velocities. And we're saying that this is consistent with the previously developed model that has liquid water at depth" under the surface, Hansen said.
The Cassini spacecraft, operated in a joint U.S.-European mission, flew close over the surface of Enceladus in March and actually through a plume, collecting samples of ice and gas.
"There are only three places in the solar system we know or suspect to have liquid water near the surface -- Earth, Jupiter's moon Europa and now Saturn's Enceladus," Joshua Colwell of the University of Central Florida, another of the researchers, said in a statement.
"Water is a basic ingredient for life, and there are certainly implications there. If we find that the tidal heating that we believe causes these geysers is a common planetary systems phenomenon, then it gets really interesting," Colwell added.
