Massive asteroid to ‘hit earth’ next month?

Written by | January 27, 2017 | 0
NASA has predicted that an enormous asteroid will pass by Earth next week, others are speculating it might be rather more dangerous. NASA has stated that although the asteroid will enter our orbit, it will not come into contact with the planet. NASA spots mysterious 8,000-year-old earthworks in Kazakhstan But some conspiracy theorists claim that the asteroid will come into contact with earth, causing not only a series of tsunamis, but boiling the seas in the process too, the Damir Zakharovich, a Russian conspiracy theorist, says that the asteroid will hit the planet on 16 February. Someones Bones ‘Zakharovich claimed “NASA is lying through its teeth.” “It is not conceivable that they do not know the truth. We have seen the data! The object they call WF9 left the

NASA’s new discovery, a rare comet to be visible from Earth for the first time

Written by | January 2, 2017 | 0
One may be able to see a new NASA discovery just by binoculars this week for the first time. NASA scientists have discovered a rare comet, which would then head back into outer reaches of the solar system for an orbit. Paul Chodas, manager of NASA’s Centre for Near-Earth Object (NEO) Studies at the Jet Propulsion Laboratory in the US revealed that the newly discovered comet C/2016 U1 NEOWISE has a good chance of becoming visible through good pair of binoculars. Comet C/2016 U1 NEOWISE will be in the southeastern sky shortly before dawn, as seen from the northern hemisphere during the first week of 2017. However the comet is not considered a threat to our planet even after being visible to skywatchers at Earth this week. It is moving farther south each day and it will reach its closest

Written by | December 5, 2016 | 0
Capping a year of successful launches, Indian Space Research Organisation is all set to launch PSLV-C36 carrying remote sensing satellite RESOURCESAT-2A from the spaceport of Sriharikota on December 7, the space agency said. The 44.4 metre tall PSLV C36 is expected to place the 1,235 kg RESOURCESAT-2A into an 827 km polar Sun Synchronous Orbit in about 18 minutes after lift off. The Polar Satellite Launch Vehicle-C36, in its 38th flight, will blast off at 10.24 AM from the first launch pad at the Satish Dhawan Space Centre, Sriharikota, about 125 km from here, ISRO said on its website. The mission life of the satellite is five years. RESOURCESAT-2A is a remote sensing satellite developed by ISRO and succeeds RESOURCESAT-1 and RESOURCESAT-2 launched in 2003 and 2011, respectively. It is intended

NASA’s most powerful space telescope completed

Written by | November 3, 2016 | 0
NASA has successfully completed building its largest space telescope, which will be 100 times more powerful than the Hubble probe and may find the first galaxies that formed in the early universe. The James Webb Space Telescope will be the successor to NASA’s 26-year-old Hubble Space Telescope. The Webb telescope’s infrared cameras are so sensitive that it needs to be shielded from the rays of the Sun. A 5-layer sunshield of the sizer of a tennis court will prevent the background heat from the Sun from interfering with the telescope’s infrared sensors. The five sunshield membrane layers are each as thin as a human hair. The layers work together to reduce the temperatures between the hot and cold sides of the observatory by about 298 degrees Celsius. Each successive layer of

Earth, other planetary objects shared similar chemical origin

Written by | September 15, 2016 | 0
Ontario: Earth and other planetary objects formed in the early years of the Solar System share similar chemical origins, suggests a new finding. Neodymium-142 (142Nd) is one of seven isotopes found in the chemical element neodymium which is widely distributed in the Earth’s crust and most commonly used for magnets in commercial products like microphones and in-ear headphones. In 2005, a small variation in 142Nd was detected between chondrites, which are stony meteorites, considered essential building blocks of the Earth and terrestrial rocks. These results were widely interpreted as an early differentiation of the interior of the Earth (including the crust and mantle) and these chondrites within the first 30 million years of its history. The new results published by the journal Nature

India to use more satellites for public services, e-governance: ISRO chief

Written by | September 2, 2016 | 0
Bengaluru: Making optimal utilisation of its space assets, India will use more satellites to deliver public services and ensure e-governance, said a top official on Thursday. “We are working with about 60 departments of the central government and all state governments for delivery of public services and enabling e-governance, using our various satellites,” said state-run Indian Space Research Organisation Chairman A.S. Kiran Kumar at a space-related event here. Currently, only 15-20 central and state departments use the space agency’s satellites for various activities, including communications, broadcasting, weather forecasting, mapping, disaster management, navigation and surveillance. “We have demonstrated over the years that space technology and its applications can be effectively

Space radio signals point to alien life

Written by | September 1, 2016 | 0
Scientists in Russia have detected a radio signal, possibly transmitted by a star system 94 light-years away, sparking speculation that this may be an attempt by intelligent extraterrestrial life to contact our Solar System. HD 164595, a system few billion years older than the Sun but centred on a star of comparable size and brightness, is the purported source of a signal found with the RATAN-600 radio telescope in Russia. This system is known to have one planet, a Neptune-sized world in a very tight orbit, making it unattractive for life. However, there could be other planets in this system that are still undiscovered. Scientists speculate that the transmission could be from a technically proficient society. The patch of sky from which the signal seems to be coming agrees in the east-west

Flooded canyons found on Saturn’s moon Titan: NASA

Written by | August 11, 2016 | 0
Washington: NASA’s Cassini spacecraft has discovered steep-sided canyons, hundreds of meters deep, on Saturn’s moon Titan that are flooded with liquid hydrocarbons. The finding represents the first direct evidence of the presence of liquid-filled channels on Titan, as well as the first observation of the deep canyons, NASA said. Scientists analysed Cassini data from a close pass the spacecraft made over Titan in May 2013. During the flyby, Cassini’s radar instrument focused on channels that branch out from the large, northern sea Ligeia Mare. The observations show that the channels – in particular, a network of them named Vid Flumina – are narrow canyons, generally less than a kilometre wide, with slopes steeper than 40 degrees. The canyons also are quite deep – those measured

Solar-powered device to help make beer from urine!

Written by | July 31, 2016 | 0
London: Scientists have created a solar-powered device to extract water and fertiliser from human urine that could be used to grow crops needed to produce beer. The device, developed by researchers from University of Ghent in Belgium, uses solar energy to heat the urine that is collected and dumped into a tank. As the urine evaporates, it is pushed through a “special” membrane that separates and collects water and other material, ‘Techxplore’ reported. According to researchers, this process removes approximately 95 per cent of the ammonia that is present in urine, making it clean enough to drink. However, realising that many people may not be ready for a sample taste, researchers also have plans to use the water and the fertiliser they make from the other materials extracted

‘Organic’ computers come closer to reality

Written by | July 15, 2016 | 0
Washington: What if your computer was organic too? A team of researchers has come one step closer to making nature meet science. The Lomonosov MSU researchers in collaboration with their German colleagues from the Institute of Polymer Research in Dresden (Leibniz Institute) managed to find a molecule that, to their opinion, could give the impetus to the development of organic electronics. Scientists found that a derivative of [3]-radialene, a molecule known to the science for nearly 30 years, can be used to create organic semiconductors. Co-author Dmitry Ivanov believes that the achievement will greatly contribute to the development of organic electronics and, in particular, to fabrication of organic light emitting diodes and new classes of organic solar cells. “We decided to design a completely

Nasa’s Juno probe beams back first image of Jupiter

Written by | July 13, 2016 | 0
Washington: The camera aboard Nasa’s Juno mission has sent back some of the first images of Jupiter along with three of its four largest moons taken after the spacecraft entered orbit around the king of planets on 4 July. Juno’s visible-light camera was turned on six days after Juno fired its main engine and placed itself into orbit around the largest planetary inhabitant of our solar system. The first high-resolution images of the gas giant Jupiter are still a few weeks away. “This scene from JunoCam indicates it survived its first pass through Jupiter’s extreme radiation environment without any degradation and is ready to take on Jupiter,” said Scott Bolton, from the Southwest Research Institute in San Antonio. The new view was obtained when the spacecraft was 4.3 million km from

SpaceX launches two satellites into orbit; fails to recover rocket

Written by | June 17, 2016 | 0
New Delhi: SpaceX has successfully launched two rockets into orbit but sadly, has failed in the attempt to recover its Falcon 9 rocket. It failed in an attempt to land the first stage of its rock undamaged on a barge in the Atlantic. Apparently, the rocket malfunctioned some 330 feet (70 meters) off the ground and was in flames when it reached the platform on the powered barge known as a drone ship live images via a SpaceX webcast showed. “Ascent phase & satellites look good, but booster rocket had a RUD on droneship,” SpaceX chief Elon Musk wrote on Twitter using an acronym for “rapid unscheduled disassembly,” or explosion. The rocket shook the barge when it landed, causing the ship’s camera to freeze. The final images showed the craft standing upright, enveloped in flames and

New bionic leaf can turn sunlight into liquid fuel

Written by | June 4, 2016 | 0
Scientists have developed a bionic leaf that uses solar energy to split water molecules and hydrogen-eating bacteria to produce liquid fuels, that surpasses the efficiency of photosynthesis seen in fastest growing plants. “Before, people were using artificial photosynthesis for water-splitting, but this is a true A-to-Z system, and we’ve gone well over the efficiency of photosynthesis in nature,” said Daniel Nocera, a professor at Harvard University in the US. While the study shows the system can be used to generate usable fuels, its potential does not end there, said Pamela Silver, a professor at Harvard Medical School. Dubbed “bionic leaf 2.0,” the new system builds on previous work by Nocera, Silver and colleagues which – though it was capable of using

Ancient Mars was once washed over by mega-tsunamis

Written by | May 21, 2016 | 0
Washington: Billions of years ago, mega-tsunamis scarred the Martian landscape, yielding evidence of cold, salty oceans conducive to sustaining life, according to a recent study. The geologic shape of what were once shorelines through Mars’ northern plains convinces scientists that two large meteorites, hitting the planet millions of years apart, triggered a pair of mega-tsunamis. “About 3.4 billion years ago, a big meteorite impact triggered the first tsunami wave. This wave was composed of liquid water. It formed widespread backwash channels to carry the water back to the ocean,” said principal investigator Alberto Fairen. The team found evidence for another big meteorite impact, which triggered a second tsunami wave. In the millions of years between the two meteorite impacts and their

Study: Bene Israel community in India carries Jewish gene

Written by | May 11, 2016 | 0
Washington: A new study reveals the Bene Israel community in the western part of India carries genetic proof of the Jewish roots. They anyway, have always considered themselves Jewish. “Almost nothing is known about the Bene Israel community before the 18th century, when Cochin Jews and later Christian missionaries first came into contact with it,” says researcher Yedael Waldman. “Beyond vague oral history and speculations, there has been no independent support for Bene Israel claims of Jewish ancestry, claims that have remained shrouded in legend,” he added. “Human genetics now has the potential to not only improve human health but also help us understand human history,” says another reasearcher Prof. Eran Halperin. According to their oral history, the Bene Israel people descended

Higher usage of coal is leading to less rainfall

Written by | May 3, 2016 | 0
Washington: A new study has found that rapid increase of coal usage in fast-growing Asian countries such as India, may weaken the monsoon systems and reduce the amount of rainfall. Coal mining is responsible for human made Sulphur dioxide (SO2) emissions, which drive up concentrations of sulphate aerosols in the atmosphere. These aerosols may also lower surface temperatures by reflecting sunlight skyward. Coal burning, despite recent signs of having peaked in China and pledges made at the Paris Climate talks in December last year, remains the primary source of electric power in Asia. At one extreme, economic growth and energy demand in China, India and other fast-growing Asian nations would lead to rapid increases in coal use, resulting in more significant climate impacts; at the other, Asia

How the Moon got mysterious ‘tattoos’ decoded

Written by | April 30, 2016 | 0
NASA scientists have found new insights into how the Moon got its mysterious “tattoos” – swirling patterns of light and dark found at over a hundred locations across the lunar surface. “These patterns, called ‘lunar swirls,’ appear almost painted on the surface of the Moon,” said John Keller of NASA’s Goddard Space Flight Centre in US. “They are unique; we’ve only seen these features on the Moon, and their origin has remained a mystery since their discovery,” Keller said. Lunar swirls can be tens of miles across and appear in groups or just as an isolated feature. Previous found that they appear where ancient bits of magnetic field are embedded in the lunar crust and the bright areas in the swirls appear to be less weathered than their surroundings. Many things can cause

New method to forecast Indian monsoon early

Written by | April 22, 2016 | 0
New Delhi: A recent study has developed a novel prediction method to forecast monsoon significantly earlier than previously possible. A team of scientists developed the method based on a network analysis of regional weather data, and will propose this approach to the Indian Meteorological Department. The heavy summer rains are of vital importance for millions of farmers feeding the subcontinent’s population. Future climate change will likely affect monsoon stability and hence makes accurate forecasting even more relevant. “We can predict the beginning of the Indian monsoon two weeks earlier, and the end of it even six weeks earlier than before – which is quite a breakthrough, given that for the farmers every day counts,” says Veronika Stolbova from the Potsdam Institute for Climate

Your voice can be tool to influence others

Written by | April 19, 2016 | 0
Washington: Why is it that some speakers influence us powerfully, while others with good voices don’t? According to a recent study, it is all about the pitch. The University of Illinois study found that people whose voices went down in pitch early on in an interaction were more likely to be seen as dominant and influential than those whose vocal pitch went up early in conversation. Those viewed as dominant also were more likely to convince others to go along with their ideas than those seen as less dominant. In another report based on the same data, the researchers found that dominant participants were not considered more prestigious, esteemed or admirable by their peers, however. Those judged to be admirable, but not dominant, also tended to excel at influencing others. “What excites me

‘Only one in five people tell the truth on Facebook’

Written by | April 7, 2016 | 0
Less than 20 per cent of people portray themselves truthfully on social networking websites such as Facebook and Twitter, a new UK-based study has found. According to the survey of 2,000 Britons, just 18 per cent represent themselves accurately, while the huge majority only post content which makes their lives look more interesting to their friends and family. The results also showed that men are more likely to lie through their social networking profiles than women. Nearly half (43 per cent) of men admitted that their social media profile is not an accurate representation of their real lives. Almost one third of participants said their profile pages on Facebook and Twitter are “pretty accurate, just with all the boring bits removed.” Nearly 14 per cent admitted that their profiles make
