New Delhi: A novel theory by three Indian scientists has paved way to unlock the mysteries of the ionhole structures - a localized plasma region where the ion density is lower than the surrounding plasma. Harikrishnan Aravindakshan, Prof. Amar Kakad, and Prof. Bharati Kakad from the Indian Institute of Geomagnetism (IIG), an autonomous institute under the Department of Science and Technology, have developed thetheory. Prof. Peter Yoon of the University of Maryland, USA also joined the Indian scientists. The theory solves every bit of uncertainty regarding the conflict between the observations from Magnetospheric Multiscale (MMS) Mission. It’s a NASA robotic…

New Delhi: Indian Scientists have indigenously designed and developed a low-cost optical spectrograph that can locate sources of faint light from distant quasars and galaxies, regions around supermassive black-holes around the galaxies, and cosmic explosions. Named Aries-Devasthal Faint Object Spectrograph & Camera (ADFOSC), the instrument was designed and developed by Aryabhatta Research Institute of observational sciences (ARIES), Nainital, an autonomous institute of the Department of Science and Technology (DST), Government of India. It is about 2.5 times less costly compared to imported ones and can locate sources of light with a photon-rate as low as about 1 photon per second.…
