Pune, May 20 (PTI) AstroSat, India's first dedicated astronomy mission which is into space since 2015, has detected the birth of a black hole for the 500th time, Pune-based research institution IUCAA has said, a development scientists termed as a remarkable achievement .

Black holes are objects with a gravitational pull so strong that not even light can escape. They are the subjects of intense scrutiny from astronomers from all over the world. Scientists across the world are studying their formation.

Jamshedpur, May 11 (PTI) Scientists of CSIR-National Metallurgical Laboratory in Jamshedpur have developed a technology to produce corrosion-resistant rebar.

Principal Scientist Ashok Kumar Mohanty said on Wednesday that rust is formed on rebar when it is exposed to water and moisture. If rusted rebar is used to make concrete, the longevity reduces as rusted rebar does not bond properly with cement.

Kolkata, May 10 (PTI) Nobel Laureate mathematical physicist Roger Penrose has said that the present universe did not start with the Big Bang and that there was another universe before the present one.

Traces of the older universe can be discovered in present black holes and certain electromagnetic radiation spots in the sky, Penrose, said in his address at a virtual meet at the Saha Institute of Nuclear Physics here from Oxford on Monday.

Kanpur: The Indian Institute of Technology, Kanpur and the Ordnance Factory Medak, Telangana, a unit of Armoured Vehicles Nigam Limited, developed India's first soft recovery system for supersonic projectiles.

This recovery system can stop a 30mm supersonic projectile moving at Mach 3 - three times the speed of sound - at a distance of nearly 50 meters.

According to a release, the technology has been developed under leadership of Nachiketa Tiwari of IIT-K and Alok Prasad, General Manager of Ordnance Factory MedaK.

TAIYUAN, Feb. 26 (Xinhua) -- The city of Yangquan in north China's Shanxi Province on Friday issued a license to Baidu for the commercial operation of unmanned autonomous driving services -- the first license of its kind issued in China.
