NASA to conduct long term space flight experiment on Twins

 

Written by Dr. Tony Phillips

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Consider a pair of brothers, identical twins. One gets a job as an astronaut and rockets into space. The other gets a job as an astronaut, too, but on this occasion he decides to stay home. After a year in space, the traveling twin returns home and they reunite.

Are the identical twins still … identical?

NASA is about to find out.

NASA’s Cassini spacecraft data reveals Saturn’s moon Enceladus has underground Ocean

NASA - National Aeronautics and Space AdministrationWashington, D.C. -  Evidence that Saturn’s moon Enceladus harbors a large underground ocean has been uncovered by NASA’s Cassini spacecraft and Deep Space Network, furthering scientific interest in the moon as a potential home to extraterrestrial microbes.

Researchers theorized the presence of an interior reservoir of liquid water in 2005 when Cassini discovered water vapor and ice spewing from vents near the moon’s south pole. New data on the moon’s gravity field reported in the April 4th, 2014, edition of the journal Science strengthen the case for an ocean hidden inside Enceladus.

This diagram illustrates the possible interior of Saturn's moon Enceladus based on a gravity investigation by NASA's Cassini spacecraft and NASA's Deep Space Network, reported in April 2014.

NASA says Earth and Mars moving closer together, converging for an “Opposition of Mars” in April

 

Written by Dr. Tony Phillips

NASA - National Aeronautics and Space AdministrationWashington, D.C. – By the time you finish reading this story, you’ll be about 1,000 km closer to the planet Mars.

Earth and Mars are converging for a close encounter. As March gives way to April, the distance between the two planets is shrinking by about 300 km every minute. When the convergence ends in mid-April, the gulf between Earth and Mars will have narrowed to only 92 million km–a small number on the vast scale of the solar system.

NASA reports United States to be treated to a series of Lunar Eclipses starting April 15th, 2014

 

Written by Dr. Tony Phillips

NASA - National Aeronautics and Space AdministrationWashington, D.C. – For people in the United States, an extraordinary series of lunar eclipses is about to begin.

The action starts on April 15th when the full Moon passes through the amber shadow of Earth, producing a midnight eclipse visible across North America. So begins a lunar eclipse tetrad—a series of 4 consecutive total eclipses occurring at approximately six month intervals. The total eclipse of April 15th, 2014, will be followed by another on October 8th, 2014, and another on April 4th, 2015, and another on September 28th 2015.

Astronomers look to make bigger Telescopes like NASA’s Hubble and Spitzer Space Telescopes

 

Written by Tony Phillips
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – More than 400 years ago, Galileo turned a primitive spyglass toward the sky, and in just a few nights learned more about the unseen heavens than all of the scientists and philosophers before him, combined.

Since then astronomers have been guided by a simple imperative: Make Bigger Telescopes. As the 21st century unfolds, the power of optics has grown a million-fold.

NASA’s Hubble Space Telescope catches images of Asteroid breaking up

 

Written by Tony Phillips

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA’s Hubble Space Telescope has recorded the never-before-seen break-up of an asteroid into as many as 10 smaller pieces. Fragile comets, comprised of ice and dust, have been seen falling apart as they approach the sun, but nothing like this has ever before been observed in the asteroid belt.

“This is a rock, and seeing it fall apart before our eyes is pretty amazing,” said David Jewitt of the University of California at Los Angeles, who led the astronomical forensics investigation.

This series of Hubble Space Telescope images reveals the breakup of an asteroid over a period of several months starting in late 2013. The largest fragments are up to 180 meters (200 yards) in radius.

International Space Station celebrates 10 years of service, looks forward to 10 more

 

Written by Tony Phillips
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – A lot can happen in 10 years. Over the past decade an international laboratory, widely known but often under-appreciated, has been producing results at an extraordinary rate.

Using its unique capabilities, engineers have developed a precision robotic arm that helps surgeons remove tumors from the human brain; experimenters have learned to start fires without flames—an anti-intuitive technology that could lead to super-efficient auto engines; physicists have counted hundreds of thousands of anti-matter particles among normal cosmic rays, a telltale sign of mysterious dark matter.; researchers have gathered atoms into exotic forms, creating the building blocks of futuristic smart materials; …and much more.

NASA uses satellites, aircraft, and high-altitude balloons to investigate California’s extreme drought

NASA - National Aeronautics and Space AdministrationWashington, D.C. – California is supposed to be the Golden State.  Make that golden brown.

The entire west coast of the United States is changing color as the deepest drought in more than a century unfolds.  According to the U.S. Department of Agriculture and NOAA, dry conditions have become extreme across more than 62% of California’s land area—and there is little relief in sight.

NASA reports Herschel Space Observatory discovers water vapor on Dwarf Planet Ceres

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Scientists using the Herschel space observatory have made the first definitive detection of water vapor on the largest and roundest object in the asteroid belt, dwarf planet Ceres.

“This is the first time water vapor has been unequivocally detected on Ceres or any other object in the asteroid belt and provides proof that Ceres has an icy surface and an atmosphere,” said Michael Küppers of ESA in Spain, lead author of a paper in the journal Nature.

NASA’s AIM spacecraft examines Electric Blue Clouds forming over Antarctica

 

Written by Dr. Tony Phillips
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Data from NASA’s AIM spacecraft show that noctilucent clouds are like a great “geophysical light bulb.” They turn on every year in late spring, reaching almost full intensity over a period of no more than 5 to 10 days.

News flash: The bulb is glowing.

As December unfolds, a vast bank of noctilucent clouds is blanketing Antarctica. It started on November 20th as a tiny puff of electric-blue and quickly expanded to overlie nearly the entire continent. AIM is monitoring the progress of the clouds as they swirl and ripple around the south pole.
