  A radio signal originating from atomic hydrogen in an extremely distant galaxy was detected by the Giant Metrewave Radio Telescope (GMRT) located in Pune. This is the largest astronomical distance over which such a signal has been picked up. The findings have been published in the scientific journal  Monthly Notices of the Royal Astronomical Society . Astronomers from McGill University in Canada and the Indian Institute of Science (IISc) in Bengaluru have used data from the telescope to detect atomic hydrogen.  GMRT is a low-frequency radio telescope that helps investigate various radio astrophysical problems ranging from nearby solar systems to the edge of the observable universe.  Atomic hydrogen is the basic fuel required for star formation in a galaxy. When hot ionised gas from the surrounding medium of a galaxy falls onto the universe, the gas cools and forms atomic hydrogen. This then becomes molecular hydrogen and eventually leads to the formation of stars.  www.downtoearth.or

  The primary mandate of HSFC is to spearhead ISRO’s Gaganyaan programme through co-ordinated efforts and focus all the activities that are carried out in other ISRO centres, research labs in India, Indian academia and Industries towards accomplishing the mission. HSFC, as the lead Centre for Human space flight activities conforms to high standards of reliability and human safety in undertaking R&D activities in new technology areas, such as life support systems, Human Factors Engineering, Bioastronautics, Crew training and Human rating & certification. These areas would constitute important components for future sustained human space flight activities like rendezvous and docking, space station building and interplanetary collaborative manned missions to Moon/Mars and near-earth asteroids. Gaganyaan Gaganyaan project envisages demonstration of human spaceflight capability by launching crew of 3 members to an orbit of 400 km for a 3 days mission and bring them back safely to ear
