Power Ministry, DRDO Signs MoU for Early Warning System for Hydro Projects

The Power Ministry signed a memorandum of understanding (MoU) with the Defence Research and Development Organization (DRDO) for the implementation of an early warning system for vulnerable hydro projects or power stations.
The ministry and the DRDO will jointly work towards developing suitable mitigation measures against avalanches, landslides, glaciers, glacial lakes and other geo-hazards.
The expertise of the DRDO will also be utilized in developing comprehensive Early Warning System (EWS) for vulnerable hydro projects/ power stations in hilly regions.
The ministry has taken the initiative of implementing Early Warning System (EWS) in the hydro power projects especially those located in upper reaches of hilly regions.
The EWS is an integrated system of hazard monitoring, forecasting and prediction, disaster risk assessment, communication and preparedness for timely action to reduce disaster risks in advance of hazardous events.

Scientists Discover "Poor Old Heart" of the Milky Way Galaxy

Scientists discovered an ancient galactic core at the centre of the Milky Way, which they are calling as the heart of our galaxy. The cluster of 18,000 stars is from our galaxy's infancy. The researchers used cutting-edge technology, including the most accurate three-dimensional map of the Milky Way ever compiled and neural network that analysed around two million stars. Previous studies had pointed towards this, but it is the first time that scientists have so emphatically announced the discovery of remnants of the past.
The 18,000 stars are from a time when the Milky Way was just a compact collection of proto-galaxies coming together to form a bigger thing.

NASA Formally Retires Mars InSight Lander after 4-year Mission

NASA formally retired its Mars InSight lander, the first robotic probe specially designed to study the deep interior of a distant world, four years after it arrived on the surface of the red planet (Mars).
Mission controllers at NASA's Jet Propulsion Laboratory (JPL) near Los Angeles determined the mission was over when two consecutive attempts to re-establish radio contact with the lander failed, a sign that InSight's solar-powered batteries had run out of energy.
InSight landed on Mars in late November 2018 with instruments designed to detect planetary seismic rumblings never before measured anywhere but Earth, and its original two-year mission was later extended to four.
From its perch in a vast and relatively flat plain called Elysium Planitia just north of the planet's equator, the lander has helped scientists gain new understanding of Mars' internal structure.
Researchers said InSight's data revealed the thickness of the planet's outer crust, the size and density of its inner core and the structure of the mantle that lies in between.

Golden Jubilee of Telescope Celebrated in TN's Tirupathur

The Vainu Bappu observatory celebrated the golden jubilee of its Vainu Bappu 40-inch optical telescope at Kavalur in Tirupathur district of Tamil Nadu. It was installed in 1972 and comes with a mirror with a diameter of 102 cm.
The telescope set up by Professor Vainu Bappu has played a significant role in astronomy with major discoveries like the presence of rings around the planet Uranus, a new satellite of Uranus, the presence of an atmosphere around Ganymede which is a satellite of Jupiter.
Several important kinds of research were conducted with the telescope, including the discovery and study of many 'Be Stars', Lithium depletion in giant stars, optical variability in Blazars, and the dynamics of the famous supernova SN 1987A.
