Urban areas are currently responsible for ~70% of the global energy-related carbon dioxide (CO2) emissions, and rapid ongoing global urbanization is increasing the number and size of cities. Thus, understanding city-scale CO2 emissions and how they vary between cities with different urban densities is a critical task. While the relationship …
Mumbai: Even as Nasa’s $2.5 billion Curiosity mission is beginning its scientific activity on the surface of the Red Planet, the space agency on Monday announced another mission to Mars which has been designated as InSight. Slated for launch in 20I6, the primary role of the In-Sight mission would be …
NASA climatologist James Hansen made headlines during the US heatwave of 1988, declaring in testimony to Congress and during interviews on prime-time television that a build-up of greenhouse gases was increasing the probability of weather extremes. Now, as much of the United States sizzles through another torrid summer and the …
If Martians exist, those in the vicinity of the Gale Crater were in for a treat this Monday: Curiosity reached their planet. NASA’s Jet Propulsion Laboratory erupted in cheers when the unmanned rover aced its landing, having braved the much-discussed seven minutes of terror in a feat of creative engineering …
NASA’s Curiosity rover has transmitted its first colour photo and a low-resolution video showing the last two-and-a-half minutes of its dramatic dive through Martian atmosphere, giving a sneak peek of a spacecraft landing on another world. As thumbnails of the video flashed on a big screen late Monday, scientists and …
Nasa: Extreme Summers To Become Routine, Global Warming To Blame. Washington: Most of Earth’s land areas might experience an extreme summer heat wave than they did in the middle of 20th century, Nasa scientists have warned. Earth’s northern hemisphere, which comprises of 90% of the planet’s land has become much …
National Aeronautics and Space Administration (NASA) of the United States opened a new chapter in the history of interplanetary exploration on Monday when its $2.5 billion nuclear-powered robot, Curiosity, beamed back pictures from the surface of Mars. The one-tonne mobile lab is the largest rover ever sent to Mars, and …
In a flawless, triumphant technological tour de force, a plutonium-powered rover the size of a small car was lowered at the end of 25-foot-long cables from a hovering rocket stage onto Mars early on Monday morning. The rover, called Curiosity, ushers in a new era of exploration that could turn …
The percentage of the earth’s land surface covered by extreme heat in the summer has soared in recent decades, from less than 1 percent in the years before 1980 to as much as 13 percent in recent years, according to a new scientific paper. Smog from peat fires outside Moscow …
The US space agency has just landed a huge new robot rover on Mars. The one-tonne vehicle, known as Curiosity, was reported to have landed in a deep crater near the planet's equator at 06:32 BST (05:32 GMT). It will now embark on a mission of at least two years …
"It is too early to proclaim the 'ice sheet's future doom'" caused by climate change, lead author Kurt Kjaer of the University of Copenhagen wrote in a statement of the findings in Friday's edition of the journal Science. An examination of old photos taken from planes revealed a sharp thinning …
Greenland's surface ice cover melted this month over a larger area than ever detected in more than 30 years of satellite observations, NASA said recently. According to measurements from three separate satellites analyzed by NASA and university scientists, an estimated 97 per cent of the ice sheet surface thawed at …
NASA, the US space agency has included two Indian innovators for its conference on waste management. Mr Nitin Gupta from Attero Recycling and Mr Anshu Goonj from Goonj are among nine innovators from across the globe that made it to the NASA conference on waste management, which started yesterday. Supported …
WASHINGTON, 12 JULY: US astronomers using the Hubble Space Telescope have discovered a fifth and tiniest moon yet orbiting the icy dwarf planet Pluto. The mini-moon is estimated to be irregular in shape and between 10 km and 25 km across. It is visible as a speck of light in …
Washington: The claim by Nasa scientists that they have discovered a new form of bacteria which thrive on arsenic has been disapproved by two new studies, which say the bugs can’t substitute arsenic for phosphorus to survive. Two scientific papers, published in the journal Science, refuted the 2010 Nasa finding …
Astronomers: ‘Unseen Substance’ Spotted For First Time. Washington: For the first time, astronomers have discovered a giant string of invisible dark matter across the universe between a pair of galaxy clusters. The universe is thought to be filled with such strings of dark matter, a mysterious substance that cannot be …
The U.S. space agency NASA said Thursday that it was leaving the door open to reviving a canceled plan for a major Southeast Asia climate study that may have run afoul of internal Thai politics. No decision has been made "on whether NASA will be able to fly the mission …
Beijing: A Chinese spacecraft carrying three astronauts docked manually with an orbiting module on Sunday, a first for the country as it strives to match American and Russian exploits in space. The Shenzhou 9 capsule’s maneuver with the Tiangong 1 module was shown live on national television. It follows a …
Nasa Spacecraft Suggests Water Source On Lunar South Pole Washington: Scientists claim to have found new evidence which suggests that the largest crater on the south pole of the moon may be tantalizingly rich in ice. The interiors of polar craters on the moon are in nearly perpetual darkness, making …
Antarctica was much warmer and wetter that helped plant life to thrive some 20 million years ago, a new Nasa research has suggested. Examining plant-leaf wax remnants in sediment core samples taken from under the Ross Ice Shelf of Antarctica, researchers found that summer temperatures along the Antarctic coast 15 …
