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 …
Building on the success of Curiosity’s Red Planet landing, Nasa has announced plans for a robust multi-year Mars programme, including a new robotic science rover set to launch in 2020. The announcement comes a day after Nasa released the results of the first soil tested by the Curiosity rover, which …
Nasa plans to send a new rover to Mars in 2020 as it prepares for a manned mission to the Red Planet, said the US space agency. The announcement came yesterday a day after Nasa released the results of the first soil tested by the Curiosity rover, which found traces …
Mercury is as cold as ice. Indeed, Mercury, the closest planet to the Sun, possesses a lot of ice — 100 billion to one trillion tonnes — scientists working with Nasa’s Messenger spacecraft reported on Thursday. Sean C Solomon, the principal investigator for Messenger, said there was enough ice there …
Scientists on Thursday announced new evidence that Mercury, the planet orbiting nearest the sun, hosts massive caches of ice and revealed new information on how water reached our solar system’s inner planets. “The new data indicate the water ice in Mercury’s polar regions, if spread over an area the size …
NEW DELHI: The combined rate of melting for the ice sheets covering Greenland and Antarctica has increased during the last 20 years says a landmark study published Thursday in the journal Science. The study was carried out by an international team of 47 experts from 26 laboratories supported by NASA …
India’s “Silicon Valley” Bengaluru has been rated among top polluted megacities in the world, claims a new study, using data collected by Nasa’s high-tech satellites. Scientists at Tel Aviv University tracked pollution trends for 189 megacities, including Mumbai, New York City and Tokyo, by analysing eight years’ worth of data …
Punjab and Haryana may have given themselves a clean chit over allegations of being directly responsible for the hazardous smog that engulfed the Delhi region, but the Centre today clearly held the two states accountable for the 12-day “extreme pollution episode” on the basis of “scientific analysis” conducted by it. …
Sat Photos Reveal Alarming Trend Washington: Greenland is losing an average of 200 million tonnes of ice every year since 2003, which could have a big impact on sea levels, scientists claim. The latest analysis by scientists studying the changing mass of the island using satellite data backs the previously …
Days after Delhi blamed the northern states, particularly Punjab, for the choking smog hanging over Delhi's sky, the Punjab Government on Thursday strongly refuted the "unsubstantiated allegation", saying there was no scientific evidence to hold it responsible. An official team from Punjab, headed by chief secretary Rakesh Singh, is expected …
Delhi Cabinet takes help of NASA images to discover cause of the smog With the Capital facing constant haze and smog over the past many days, the Delhi Cabinet on Wednesday took help of pictures taken by the U.S. National Aeronautics and Space Administration (NASA) to find an answer to …
Washington: Nasa’s Curiosity rover which completed its first soil analysis on Mars has found minerals on the Red Planet similar to weathered basalt volcanic soils in Hawaii. X-ray diffraction image of first Martian soil sample showed the presence of crystalline feldspar, pyroxenes and olivine mixed with some non-crystalline material — …
Mars rover Curiosity has found definitive proof that water once ran across the surface of Mars, US space agency NASA announced. There is earlier evidence for the presence of water on Mars, but this evidence -- images of rocks containing ancient streambed gravels -- is the first of its kind. …
Water & Organics Began Journey To Earth On Icy Particles, Say Researchers Washington: To better understand the origin of life on Earth, Nasa researchers led by an Indian scientist are creating concoctions of organics or carbon bearing molecules, on ice in a lab. The research at Nasa’s jet propulsion laboratory …
From regulating climate systems to offering food and medicines, to being home to many plants, animals, and indigenous people, rainforests are not only a local ecosystem but their benefits extend globally. Adding to its effects is new research that shows rainforests have a huge impact on rainfall. A team from …
When environmental engineer John Feighery got an internship at NASA in the 1990s, he wanted to be an astronaut but he was given a job working with a team designing the U.S. bathroom for the space station. The small, closet-like space needed a toilet and room for hand washing, bathing …
The amount of sea ice in the Arctic has fallen to the lowest level on record, a confirmation of the drastic warming in the region. Satellites tracking the extent of the sea ice found over the weekend that it covered about 1.58 million square miles, or less than 30 per …
Washington, DC 28 August 2012 – Arctic sea ice has hit record lows with weeks still to go in the melt season, an indication of accelerating global warming. Arctic sea ice has reached the lowest level ever observed in the three decades since polar cap observations began, according to scientists …
Melbourne: A new smartphone case, made up of same material as Nasa spacecraft, claims to reduce cellphone radiation and cancer risks as it cuts the exposure by up to 95%. Although it still remains unclear as to exactly how bad the problem of cellphone radiation is, the WHO has already …
As Long As There Are History Books, Neil Armstrong Will Be In Them: Nasa Neil Armstrong, who made the “giant leap for mankind” as the first human to set foot on the moon, died on Saturday. He was 82. His family said the cause was “complications resulting from cardiovascular procedures.” …
London: Nasa’s Curiosity rover, scheduled to take its maiden test drive on the surface of Mars, on Wednesday reported its first setback when a sensor on its weather station was damaged. However, the mission team says this is not a major problem and will merely degrade some measurements, not prevent …
