Reply by the Central Pollution Control Board (CPCB) in compliance to the National Green Tribunal (NGT) order dated January 21, 2024 in the matter of ‘News item titled “Feeling anxious? Toxic air could be to blame” appearing in Times of India dated 10.10.2023’. NGT had directed CPCB to file a …
COME November 17 and sky watchers will get cricks in their necks. But it will be worth it. The Earth will wade through a spectacular rain of meteors left behind by a passing comet. The last time the planet passed through the cosmic debris in 1966, hundreds of thousands of …
Radio dish pieces which may have picked up some interesting evidence of extraterrestrial intelligence are on sale now. In 1977, search for extraterrestrial intelligence (SETI) programme was carried out by a huge Big Ear Dish at the Ohio State Radio Observatory, and it shot into fame when it picked up …
THEORIES of gravity are coming under scrutiny because of the bizarre behaviour of some spacecraft. "We have been working on this problem for several years, and we accounted for everything we could think of," says John Anderson, planetary scientist at the Jet Propulsion Laboratory, National Aeronautics and Space Administration (NASA), …
Controllers of the ill-fated Solar and Heliospheric Observatory (SOHO) are struggling to bring the spacecraft under control. Mission controllers lost the craft at the end of June, but regained contact recently. However, the craft is spinning in such a way that its solar power cells get very little sunlight. The …
In 1976 NASA's Viking spacecraft snapped a photograph of a feature on Mars that was startlingly familiar to all Earthlings: part of the rocky surface looked just like a human face. Most interpreted this Martian Mount Rushmore as a trick of light and shadow, but others credited it to alien …
FROM Einstein's equations of general relativity, Austrian physicists Joseph Lense and Hans Thirring derived in 1918 that an object that spins also twists the fabric of space-time around it. The Lense-Thirring effect is so small, however, that it has been hard to measure. An international team of Italian, Spanish and …
Look, up in the sky... No, it isn't Superman, It's an airship. And last month was the 160th anniversary of the birth of Count Ferdinand von Zeppelin, the man who started a new era in air travel. His first airship took off in July 1900 at Lake Constance, on the …
UNUSUALLY detailed pictures taken by the National Aeronautics and Space Administration's (NASA'S) unmanned spacecraft Galileo reveal that Jupiter's largest moon Ganymede has geologic hints of an early sub-surface ocean. Also seen was a chain of 13 craters, which were probably formed by impacts from a broken comet similar to the …
Satellites around the so-called giant planets in our solar system were thought to be of two broad types: large, regular satellites that are in almost circular equatorial orbits and small, irregular ones that have highly inclined orbits. Till now, the only exception to this was Uranus, which was thought to …
about 400 years after Galileo revolutionised the study of the Universe, a telescope will be commissioned on a 2,600-metre peak in northern Chile. This will be a vast improvement on the existing telescope technology. The Very Large Telescope (vlt) will, so obviously, be the largest in the world with a …
launch pads, manned colonies and perhaps even luxury sight-seeing tours. Yes, all this and more on the Moon - the most happening satellite ever since the us National Aeronautics and Space Administration (nasa) lunar probe discovered what the scientists had always expected our Moon to possess: plain, simple water. Only …
the old, frail and battered Mir spacecraft will be abandoned by December 1999, say Russian space officials. Cosmonauts on board would soon begin to manoeuvre it into a lower orbit. The officials say that a module would be launched towards Mir that would carry fuel to propel the station towards …
in the far reaches of space, cosmic thunderstorms are generating windspeeds of more than 965 kilometres per second and temperatures hotter than the Sun, report scientists. Massive clusters of galaxies are colliding at supersonic speed millions of light years away, creating intense shock and violent turbulence. However,there will be no …
two new findings by astronomers have raised hopes of discovering life elsewhere in the Universe. The first is the discovery of water vapour around stars, planets and their satellites by the European Space Agency's Infrared Space Observatory, which orbits the Earth. The second is a snapshot taken by us National …
Very soon, two satellites will be launched for measuring the changes in Earth's gravitational force due to mass changes equivalent to 1 cm of water over a quarter of a million square kilometres. The CHAMP mission (a joint German, US and French venture) in 1999 and a US National Aeronautics …
The next US National Aeronautics and Space Administration (NASA) mission to Mars will boast of a microphone on board to record the sounds of the Red Planet. These sounds, recorded by the microphone on the Mars Polar Landau, which is due to touch down on the planet in 1999, will …
easy . Just call Tethers Unlimited, a us -based company, whose areas of expertise include "hauling' all those dead satellites back home, either for a burial or for resurrection. This Washington-based company claims that the method it has developed is not only simple, but economically viable too. In fact, the …
The Moon has never had it so good. Looked at longingly by both lovers and werewolves for centuries and composed of the stuff which lends wings to poetry, today the Moon is full of a precious resource which is attracting the attention of the National Aeronautics and Space Administration ( …
After giving a detailed survey of our Universe, the Hubble Space Telescope (HST), has now provided astronomers with proofs of a newborn planet in the dust cloud surrounding a nearby star. The disk, encircling Beta Pictoris (a star 60 light years away from us), is warped, suggesting planet birth. The …
