Mars Rover Curiosity Sends First Full-Color Panorama of Its New Martian Home
360 degrees of lovely Gale Crater
By Rebecca Boyle Posted 08.09.2012
After a couple days of black-and-white imagery and blurry color thumbnails, the Mars rover Curiosity has downlinked its first full-color, 360-degree view of its new home in Gale Crater. Click past the jump to enlarge the whole thing–it’s incredible.
The image was brightened during its processing, because it’s not actually this sunny on Mars. The planet is another 50-ish million miles from the sun, and it only receives half the sunlight Earth does.
Scientist Discovers Plate Tectonics On Mars
ScienceDaily (Aug. 9, 2012) — For years, many scientists had thought that plate tectonics existed nowhere in our solar system but on Earth. Now, a UCLA scientist has discovered that the geological phenomenon, which involves the movement of huge crustal plates beneath a planet’s surface, also exists on Mars.
“Mars is at a primitive stage of plate tectonics. It gives us a glimpse of how the early Earth may have looked and may help us understand how plate tectonics began on Earth,” said An Yin, a UCLA professor of Earth and space sciences and the sole author of the new research.
Yin made the discovery during his analysis of satellite images from a NASA spacecraft known as THEMIS (Time History of Events and Macroscale Interactions during Substorms) and from the HIRISE (High Resolution Imaging Science Experiment) camera on NASA’s Mars Reconnaissance Orbiter. He analyzed about 100 satellite images — approximately a dozen were revealing of plate tectonics.

1st Photos from New Discovery Channel Telescope Unveiled
 |
One of the first images captured by the Discovery Channel Telescope in Arizona shows the barred spiral galaxy M109. The privately funded observatory took its first photos in May 2012.
CREDIT: Lowell Observatory
The Discovery Channel Telescope is an observatory with a 14-foot (4.3-meter) mirror built near Happy Jack, Ariz., by the Lowell Observatory and Discovery Communications, the parent company of television’s Discovery Channel. The telescope’s opening was marked with a gala on Saturday (July 21) at Lowell Observatory in Flagstaff and featured a keynote speech from Neil Armstrong, the first person ever on the moon.
“The First Light Gala is a historic event in the annals of Lowell Observatory,” Jeffrey Hall, director of Lowell Observatory, said in a statement. “It marks completion of our spectacular new research facility, initiation of superb projects that will bring our research to millions through our partnership with Discovery Communications. We are honored to be part of it and grateful to all who have helped make it a reality.”

Gravitational Lensing: Astronomers Spot Rare Arc from Hefty Galaxy Cluster
ScienceDaily (June 26, 2012) — Seeing is believing, except when you don’t believe what you see. Astronomers using NASA’s Hubble Space Telescope have found a puzzling arc of light behind an extremely massive cluster of galaxies residing 10 billion light-years away. The galactic grouping, discovered by NASA’s Spitzer Space Telescope, was observed as it existed when the universe was roughly a quarter of its current age of 13.7 billion years. The giant arc is the stretched shape of a more distant galaxy whose light is distorted by the monster cluster’s powerful gravity, an effect called gravitational lensing. The trouble is, the arc shouldn’t exist.
“When I first saw it, I kept staring at it, thinking it would go away,” said study leader Anthony Gonzalez of the University of Florida in Gainesville, whose team includes researchers from NASA’s Jet Propulsion Laboratory, Pasadena, Calif. “According to a statistical analysis, arcs should be extremely rare at that distance. At that early epoch, the expectation is that there are not enough galaxies behind the cluster bright enough to be seen, even if they were ‘lensed,’ or distorted by the cluster. The other problem is that galaxy clusters become less massive the further back in time you go. So it’s more difficult to find a cluster with enough mass to be a good lens for gravitationally bending the light from a distant galaxy.”

Researchers Estimate Ice Content of Crater at Moon’s South Pole
ScienceDaily (June 20, 2012) — NASA’s Lunar Reconnaissance Orbiter (LRO) spacecraft has returned data that indicate ice may make up as much as 22 percent of the surface material in a crater located on the moon’s south pole.
The team of NASA and university scientists using laser light from LRO’s laser altimeter examined the floor of Shackleton crater. They found the crater’s floor is brighter than those of other nearby craters, which is consistent with the presence of small amounts of ice. This information will help researchers understand crater formation and study other uncharted areas of the moon. The findings are published in Thursday’s edition of the journal Nature.
“The brightness measurements have been puzzling us since two summers ago,” said Gregory Neumann of NASA’s Goddard Space Flight Center in Greenbelt, Md., a co-author on the paper. “While the distribution of brightness was not exactly what we had expected, practically every measurement related to ice and other volatile compounds on the moon is surprising, given the cosmically cold temperatures inside its polar craters.”

NASA Adopts Two Spare Spy Telescopes, Each Maybe More Powerful Than Hubble
The Outer Limits: Nasa Probe Sees the ‘Edge’ of Our Solar System for First Time – and it’s Completely Different From What We Thought
Sunday, 13 May 2012
‘Nasa’s probes have seen the ‘edge’ of our solar system for the first time – and it’s completely different from what scientists thought.
Our solar system is flying through space more slowly than we thought – and Nasa’s IBEX – Interstellar Boundary Explorer – has found it doesn’t have a ‘bow shock’, an area of gas or plasma that shields our solar system as it hurtles though space
‘The sonic boom made by a jet breaking the sound barrier is an earthly example of a bow shock,’ says Dr. David McComas, principal investigator of the IBEX mission.’
