NASA Prepares its Science Fleet for Oct. 19 Mars Comet Encounter

NASA Prepares its Science Fleet for Oct. 19 Mars Comet Encounter  Prepares :NASA’s extensive fleet of science assets, particularly those orbiting and roving Mars, have front row seats to image and study a once-in-a-lifetime comet flyby on Sunday, Oct. 19.Comet C/2013 A1, also known as comet Siding Spring, will pass within about 87,000 miles (139,500 kilometers) of the Red Planet — less than half the distance between Earth and our moon and less than one-tenth the distance of any known comet flyby of Earth. Siding Spring’s nucleus will come closest…

What is science and technology ?

What is science and technology ? Science and Technology is gift from Almighty Lord for this modern civilization. We live in age of science. We can see the wonders of it around us. Actually science has made our life so easy and comfortable moreover now we can not think our daily life without science. The first wonder of science is electricity and though all creation day by day opened to us by the welfare of science.         On the other hand, technology means the articulation of a craft. Technology contributes…

Visiting Pluto

Visiting Pluto

Visiting Pluto A NASA spacecraft is about to fly by the solar system’s favorite dwarf planet. On July 14, tiny, far-flung Pluto is about to have a visitor — at least for a few hours. Visiting : NASA’s New Horizons spacecraft is speeding toward the dwarf planet. Earlier probes had flown past, orbited, crashed into or landed on every other large world that orbits the sun. Now Pluto is getting its turn. For 9.5 years, New Horizons has been traveling across nearly 5 billion kilometers of space. But in recent…

Scientists consider how to visit the closest exoplanet

Scientists consider how to visit the closest exoplanet Scientists :Even at only around 4 light-years, a trip from Earth to Proxima b might still take tens of thousands of years Scientists :By now, you probably have heard that astronomers have discovered a new exoplanet orbiting the star closest to our sun. That star, Proxima Centauri, is 4.2 light-years away. In miles, that’s like 25 trillion. The new planet’s name is Proxima b. Because its star is so relatively close, some people wonder whether it would be possible to go there.…

A famous 'ancestor' may be ousted from the human family

A famous ‘ancestor’ may be ousted from the human family Famous : A remarkably complete skeleton introduced in 2010 as “the best candidate” for the immediate ancestor of our genus Homo may just be a pretender. Instead of belonging to the human lineage, the new species of Australopithecus sediba is more closely related to other hominins from South Africa that are on a side branch of the human family tree, according to a new analysis of the fossil presented here last week at the annual meeting of the American Association…

Sunlight-powered purifier could clean water for the impoverished

Sunlight-powered purifier could clean water for the impoverished

Sunlight-powered purifier could clean water for the impoverished One-tenth of the world’s population lacks clean water. Now, researchers report they have developed a cheap solar still, which uses sunlight to purify dirty water up to four times faster than a current commercial version. The raw materials cost less than $2 per square meter. The technology will “allow people to generate their own drinking water much like they generate their own power via solar panels on their house roof,” says Zhejun Liu, a visiting scholar at the State University of New…

Nobel goes for finding brain’s ‘GPS’

Nobel goes for finding brain’s ‘GPS’

Nobel goes for finding brain’s ‘GPS’ The award covered research on how the brain keeps track of where we are by mapping our place within our environment Nobel : Many drivers now depend on a global positioning system (GPS) to navigate roads in unfamiliar towns or subdivisions. But the brain has its own GPS-like system. It helps people and other animals orient themselves in their environment. For figuring out how this brain network works, the Nobel Prize committee granted this year’s award in Physiology or Medicine to three neuroscientists. The…

A king snake’s strength is in its squeeze

A king snake’s strength is in its squeeze

A king snake’s strength is in its squeeze Strength  It’s not the size of a snake’s muscles that matter, but how it uses them. King snakes can defeat larger snakes in a wrestling match to the death because of how they coil around their prey, researchers report March 15 in the Journal of Experimental Biology. King snakes wrap around their food and squeeze with about twice as much pressure as rat snakes do, says David Penning, a functional morphologist at Missouri Southern State University in Joplin. Penning, along with colleague…

Anatomy analysis suggests new dinosaur family tree

Anatomy analysis suggests new dinosaur family tree

Anatomy analysis suggests new dinosaur family tree The standard dinosaur family tree may soon be just a relic. After examining more than 400 anatomical traits, scientists have proposed a radical reshuffling of the major dinosaur groups. The rewrite, reported in the March 23 Nature, upsets century-old ideas about dinosaur evolution. It lends support to the accepted idea that the earliest dinosaurs were smallish, two-legged creatures. But contrary to current thinking, the new tree suggests that these early dinosaurs had grasping hands and were omnivores, snapping up meat and plant matter…

Supermassive black hole gets kicked to the galactic curb

Supermassive black hole gets kicked to the galactic curb

Supermassive black hole gets kicked to the galactic curb A black hole weighing more than a billion suns appears to have gotten the boot toward the outer edges of its galaxy. Data from the Hubble Space Telescope and other observatories reveal a supermassive black hole zipping away from the center of its galaxy at a 7.5-million-kilometer-per-hour clip. It’s moving so quickly that it could leave the galaxy for good in 20 million years, says Marco Chiaberge of the Space Telescope Science Institute in Baltimore. Only gravitational waves — ripples in…
