A new multimillion-rand telescope in the Karoo will offer astronomers an unprecedented view of the stars. The MeerLICHT instrument in Sutherland will be specifically linked to the MeerKAT radio telescope array near Carnarvon in the Northern Cape. Unlike its bigger brother SALT (Southern African Large Telescope), the MeerLICHT is meant …
EXPERIMENTAL observations have amply confirmed the Big Bang theory, but some of its shortcomings have led scientists to develop the so-called inflationary theory, to pursue their bid to trace the early history of the universe. Proposed originally by Alan Guth of MIT in 1980, the inflationary theory predicts the density …
ASTRONOMERS are excited about the recent observations made by the satellite ROSATwhich provide the strongest evidence yet that as much as 90 per cent of the matter in the universe is invisiblewhose presence is indicated by its gravitational pull on matter in space. Astronomers have been searching for this invisible …
The full moon is said to drive people loony. Now, a scientist says the sun makes them murderous. V S Venkatavardhan, director of the Nehru Planetarium in Bombay, asserts major disturbances on earth occur during solar flares, which are increased eruptions of nuclear protons, electron particles and gamma rays oii …
THE CAMPAIGN by astronomers to stop artificial light in cities from affecting stellar views, which prevents them studying stars, is gaining a wider audience. Relentless light from surrounding cities has shut down the largest telescope at Mount Wilson in Southern California. Scientists believe artificial lights should be shielded so that …
THREE-and-a-half centuries after the rest of the world, the Catholic church has finally discovered the sun does not revolve around it, or even around the earth. The result is the rehabilitation of Pisan astronomer and pioneer of modern physical science Galileo Galilei by Pope John Paul on November 1, in …
RECENT studies by four independent teams of astronomers indicate that planetary systems resembling the young solar system may exist in nearby parts of the galaxy. Three of these studies, presented at a recent meeting of the American Astronomical Society, focussed on a star called Beta Pictoris, which is visible from …
FOR the first time ever humans have grabbed a peep-hole into the birth of the universe about 15 billion years ago. Since the Big Bang theory was first mooted in 1964, scientists have found it difficult to explain how the universe acquired its lumpy character, that is, its stars, planets …
