The researchers have finally detected the most ancient type of molecule in our universe in space for the first time ever. They used NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA) to detect helium hydride in a planetary nebula NGC 7027 about 3,000 light-years away from Earth. Helium hydride ion (HeH+) was the first molecule that ..

NASA’s flying observatory SOFIA has detected Helium hydride ion (HeH+), the first molecule that formed almost 14 billion years ago towards a planetary nebulae. It is the first type of molecule that formed in the universe after the Big Bang. At that time, ionised hydrogen and neutral helium atoms reacted to form Helium hydride ion. ..
The International Labour Organization (ILO) has recently released the report titled ‘The Safety and Health at the Heart of the Future of Work – Building on 100 years of experience’. In it, the 1984 Bhopal gas tragedy which killed thousands of people is among the world’s “major industrial accidents” of the 20th century (after 1919). ..
The scientists at University of Edinburgh have discovered a new state of physical matter – which allows atoms to exist as both solid and liquid at the same time. Until now, atoms in physical matter were understood to exist typically in one of three states — solid, liquid or gas. An international team of physicists ..
Astronomers have captured the first-ever image of a black hole, which is located in a distant galaxy known as ‘Messier 87’ (M87), through a network of 8 linked radio telescopes known as the Event Horizon Telescope (EHT) Collaboration. The black hole in the centre of M87 has a mass of more than six billion solar ..
Computer scientist Katie Bouman, who is still a graduate student at MIT has developed the algorithm to create the first image ever of a black hole. Katie has named the algorithm ‘CHIRP’ (Continuous High-resolution Image Reconstruction using Patch priors) which was needed to gather data from 8 radio telescopes across the world working under Event Horizon ..
University of Wisconsin-Madison scientist develops a new pin-sized sensor that can detect dangerous chemicals
The scientists at the University of Wisconsin-Madison in the US have developed a novel sensor that can be used in smartphone-sized devices to detect dangerous chemicals based on a unique fingerprint of absorbed and emitted light. Devices called spectrometers are light-splitting instruments that have long been both bulky and expensive, preventing their use outside the ..
Scientists from University of Michigan in the United States have found that dangerous airborne viruses can be rendered harmless on-the-fly when exposed to ‘cold plasma’ – a stream of energetic, charged fragments of air molecules. The researchers have measured the virus-killing speed and effectiveness of non thermal plasmas – the ionised, or charged, particles that ..
