NASA's WFIRST Hubble Telescope renamed after astronomer Nancy Grace Roman

  • NASA has renamed its next-generation space telescope- Wide-Field Infrared Survey Telescope (WFIRST), after the space agency's first chief astronomer Nancy Grace Roman.
  • The Nancy Grace Roman Space Telescope or Roman Space Telescope is set for launch in 2025. 
  • NASA's first Chief Astronomer Nancy Grace Roman had paved the way for space telescopes focused on the broader universe.
  • She is considered as the mother of Hubble Space Telescope, which had launched 30 years ago.

4 Indian Astronauts Resume Training in Russia for India's First Manned Mission to Space 'Gaganyaan'

  • The four cosmonauts shortlisted for Gaganyaan, India's first manned space mission, have resumed their training in Russia, after it was put on hold due to COVID-19 scare.
  • Gagarin Research & Test Cosmonaut Training Center (GCTC) resumed training of the Indian cosmonauts under the contract between Glavkosmos, JSC (part of the State Space Corporation Roscosmos) and the Human Spaceflight Center of the Indian Space Research Organisation (ISRO).

IASST Develops Electrochemical Sensing Platform

  • Institute of Advanced Study in Science and Technology (IASST), Guwahati, developed an electrochemical sensing platform.
  • It will detect carcinogenic or mutagenic compound N-nitrosodimethylamine (NDMA) and N-nitrosodiethanolamine (NDEA) that are found in food items like cured meat, bacon, some cheese, and low-fat milk.
  • It was achieved by developing a modified electrode by immobilizing carbon nanomaterials (carbon dots) in Deoxyribonucleic acid (DNA).
  • People are exposed to harmful chemicals belonging to Nitrosamine family in cured meats, bacon, some cheese, low-fat dry milk, and fish.

IIT-M Researchers Develop Low Cost Solar Parabolic Trough Collector

  • Researchers at the Indian Institute of Technology-Madras (IIT-M) have developed a low cost Solar 'Parabolic Trough Collector' (PTC) system for concentrating solar energy with industrial applications in areas such as desalination, space heating and space cooling, among others.
  • This indigenously designed and developed system was lightweight with high energy efficiency under Indian various climatic and load conditions.
  • The National Solar Mission was launched with the target of providing 20,000 MW through solar power by 2022.
  • However, lower rate of energy generation through solar power was a major roadblock in achieving this target.

Australia 'Records Fastest Internet Speed Ever'

  • Researchers in Australia claim they have recorded the fastest ever internet data speed.
  • A team from Monash, Swinburne and RMIT universities logged a data speed of 44.2 terabits per second (Tbps).
  • At that speed, users could download more than 1,000 high-definition movies in less than a second.
  • According to Ofcom, the average UK broadband speed currently is around 64 megabits per second (Mbps) - a fraction of that recorded in the recent study.

Researchers Found a New Species Fungi Named Troglomyces Twitteri

  • Researchers from the University of Copenhagen's Natural History Museum of Denmark discovered new species of parasitic fungus via Twitter.
  • The newly discovered fungus was named "Troglomyces twitteri", after Twitter.
  • The discovery was made by the biologist and associate professor Ana Sofia Reboleira of the National Natural History Museum.
  • She stumbled upon a photo of a North American millipede shared by US colleague Derek Hennen of Virginia Tech on Twitter in 2018.
  • The researcher spotted a few tiny dots on the North American millipede.

Exoplanet Climate 'Decoder' Aids Search For Life

  • After examining a dozen types of suns and a roster of planet surfaces, Cornell University astronomers have developed a practical model -- an environmental color "decoder" -- to tease out climate clues for potentially habitable exoplanets in galaxies far away.
  • Madden and Kaltenegger are co-authors of "How Surfaces Shape the Climate of Habitable Exoplanets," released May 18 in the Monthly Notices of the Royal Astronomical Society.
