First Recorded Human Voice from Earth to Another Planet and Back --NASA Mars' Curiosity Mission

 

                       Curiosity-NASA

In historic spoken words radioed to the rover on Mars and back to NASA's Deep Space Network (DSN) on Earth, NASA Administrator Charles Bolden noted the difficulty of landing a rover on Mars, congratulated NASA employees and the agency's commercial and government partners on the successful landing of Curiosity earlier this month, and said curiosity is what drives humans to explore.

Did DNA Exist Before Life Began on Earth? New Study Suggests "Yes"

 

                            275222-2388-14

 

Scientists are close to demonstrating that the building blocks of DNA can form spontaneously from chemicals thought to be present on the early Earth. If they succeed, their research implies that DNA could have predated the birth of life. “The story makes more sense if DNA nucleotides were naturally present in the environment. Organisms could have taken up and used them, later developing the tools to make their own DNA once it became clear how advantageous the molecule was— and once natural supplies began to run low,” Christopher Switzer of the University of California, Riverside said.

Neil Armstrong & "The Lost Apollo 11" Footage

 

            Armstrong-on-moon

 

After a three-year search for the lost Apollo 11 tapes and an exhaustive six-year restoration project, digitally remastered footage of the historic Moonwalk was completed in 2010. Thanks to the efforts of a dedicated tape restoration team, the enhanced footage surpasses the quality of the live broadcast that stunned an international TV audience on the day of the historic event in 1969. We've posted the video below In honor of Neil Armstrong's (image above) life and accomplishments.

"Cerataspis Monstrosa" --200 Year Old Deep-Sea Mystery Solved

 

                Georgewashin

The origin of Cerataspis monstrosa has been a mystery as deep as the ocean waters it hails from for more than 180 years. For nearly two centuries, researchers have tried to track down the larva that has shown up in the guts of other fish over time but found no adult counterpart.

Getting Closer! --Kepler Mission Captures 41 New Planets in 20 Star Systems

 

           286252main_kepler-milkyway-fov_946-710

 

Two newly submitted studies verify 41 new transiting planets in 20 star systems. These results may increase the number of Kepler's confirmed planets by more than 50 percent: to 116 planets hosted in 67 systems, over half of which contain more than one planet. The papers are currently under scientific peer-review.

"99% of the Mass of the Visible Universe Not Explained by CERN's Discovery of Higgs Boson"

 

           Irdc03

 

To get a grasp on what holds these visible forms of matter together—everything from stars to planets to people—you have to understand how quarks and gluons interact. That's the essence of quark matter physics—and the Quark Matter 2012 international conference, taking place in Washington, D.C., August 12-18. "We're studying the 99 percent of the mass of the visible universe that isn't explained by the Higgs," says Peter Steinberg, a physicist at the U.S. Department of Energy's Brookhaven National Laboratory and a participant in the Quark Matter conference.

China's Antarctic Astronomy Base in Active Search for Alien Life

 

                  Shapeimage_2

Chinese astronomers are actively searching for Earth-like planets using survey instruments in Antarctica, as they believe efforts to seek an extra-solar planet that that harbors life will soon be rewarded. "It's highly possible that human beings might find such a planet in the coming few years," said Wang Lifan, director of the Chinese Center for Antarctic Astronomy. "Such planets likely exist in the Milky Way, with a possible distance of thousands of light years from us."

"The Red Square Nebula" --Is a Colossal Supernova Brewing There?

 

           6a00d8341bf7f753ef015433fe0dba970c-800wi

 

The hot star system known as MWC 922 appears to be imbedded in a nebula creating the shape of a square. The above image combines infrared exposures from the Hale Telescope on Mount. Palomar in California, and the Keck-2 Telescope on Mauna Kea in Hawaii. The theory is that the central star or stars expelled cones of gas during a late developmental stage.

"The Moon Once Harbored a Dynamic Molten Core" --MIT (Weekend Feature)

 

            Moon_gal_big (1)

 

MIT's research on an ancient lunar rock suggests that the moon once harbored a long-lived dynamo — a molten, convecting core of liquid metal that generated a strong magnetic field 3.7 billion years ago. The findings, published in Science, point to a dynamo that lasted much longer than scientists previously thought, and suggest that an alternative energy source may have powered the dynamo.  

“The moon has this protracted history that’s surprising,” says co-author Benjamin Weiss, an associate professor of planetary science at MIT. “This provides evidence of a fundamentally new way of making a magnetic field in a planet a new power source.”

The first evidence of a planet's destruction by its aging star has been discovered by an international team of astronomers. The evidence indicates that the missing planet was devoured as the star began expanding into a "red giant" -- the stellar equivalent of advanced age.
