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 …
Washington: Planetary scientists claim to have for the first time found concrete evidence for the presence of liquid water in a comet. A team, led by Arizona University in the United States, says the finding has shattered the current paradigm that comets never get warm enough to melt the ice …
Nasa has released the first-ever 360-degree panoramic images of the Sun. Two Solar Terrestrial Relations Observatory (Stereo) satellites, launched in 2006, have gradually been drifting apart
Washington: Mysterious dark sand dunes around Mars' northern polar cap are shifting with the seasons, as carbon dioxide gas changes form and sparks landscape-altering avalanches, said a study. Imagesfrom Nasa’sMarsReconnaissance Orbiter, which hasbeen collecting data from the red planet for five years, have shown the unexpected shifts, said the research …
New government figures for the global climate show that 2010 was the wettest year in the historical record, and it tied 2005 as the hottest year since record-keeping began in 1880. The new figures confirm that 2010 will go down as one of the more remarkable years in the annals …
Washington: Lurking in the depths of a California lake, researchers found a bacteria that can thrive on arsenic, an explosive discovery that could expand the search for other life on Earth and beyond. The Nasa-funded findings redefines what science considers the necessary elements for life, currently viewed as: carbon, hydrogen, …
London: For the first time since the last Apollo landings of 1968s, scientists are planning to explore the dark side of the Moon using a manned spacecraft. Engineers with aerospace giant Lockheed Martin want to send up astronauts into stationary orbit above the planet to study it further. The American …
Researchers identified the mineral as hydrated silica Washington: American scientists claim to have found evidence that suggests Mars had a warm and wet climate which could have supported life some 3.5 billion years ago. A team, led by planetary geologists at Brown University, found mounds of a mineral deposited on …
Washington: It may sound like Hollywood science fiction, but Nasa is mulling a new one-way mission in which astronauts will be sent to another world such as Mars to settle there for ever. The US space agency has confirmed that it is carrying out feasibility studies to asses whether astronauts …
WASHINGTON, 22 OCT: A year after announcing the discovery of water molecules on the moon, Nasa scientists have now said the earth's satellite is not only rich in useful materials, it has a water cycle of its own. In fact, new studies suggest that there is a lot more water …
Washington: The universe and everything in it could end in less than 3.7 billion years from now, claims a new study. The universe, began in a Big Bang about 13.7 billion years ago, has been expanding at an ever accelerating rate ever since and according to standard cosmology models it …
Kathmandu: A new system that will allow scientists to monitor the impact of climate change in the Himalayas using images from Nasa satellites was launched in the Nepalese capital Kathmandu on Tuesday. Experts say Himalayan glaciers are melting at an alarming rate, threatening to bring floods and later drought to …
In the early and mid- 1980s, Doordarshan news would sometimes show pictures of celestial bodies taken by the US spacecraft Voyager 1 and Voyager 2. It changed our worldview. Saturn, Uranus, Jupiter and Neptune were not the vaguely spherical celestial entities depicted in encyclopedia and school textbooks. They had mountains, …
