Washington, March 20 : A team of scientists has confirmed the origin of supernovae as being produced from dying red supergiant stars.
The scientists are from the Dark Cosmology Centre at the Niels Bohr Institute, University of Copenhagen and from Queens University, Belfast.
A star is a large ball of hot gas and in its incredibly hot interior hydrogen atoms combine to form helium, which subsequently forms carbon, other heavier elements and finally iron.
When all the atoms in the centre have turned to iron the fuel is depleted and the star dies.
Washington, March 20 : An international team of scientists has come a step closer to understanding the Universe with the discovery of a fundamental building block of nature.
The recent discovery of a single top quark at the U. S. Department of Energy’s Fermi National Accelerator Laboratory near Chicago is a major breakthrough in understanding matter and energy.
Washington, March 18: German scientists have come up with a technology that can enable windows and doors to sensitise any suspicious movements, and sound an alarm.
Researchers at the Fraunhofer Institutes for Applied Polymer Research IAP in Potsdam-Golm and for Computer Architecture and Software Technology FIRST in Berlin say that the heart of their technology is a motion sensor and a special coating.
They say that their innovation may one day provide even more security by enabling window panes and glass doors to detect whether and how quickly something is moving.
According to them, if anything changes in front of the pane, or someone sneaks up to it, an alarm signal is sent to the security guard.
London, Mar 16: A thief stole 100,000 pounds worth of lead from the roofs of buildings – using Google Earth.
By using the popular Internet tool, which shows aerial photographs of towns across the world, Tom Berge was able to identify museums, churches and schools across south London with lead roof tiles.
After the 27-year-old builder found a potential target on his home computer he would scale its roof, take the valuable roof materials and abseil down the side of the building, before selling the lead to scrap metal dealers.
