News 1 - LIGO observatory set up in India


The MoU was signed between India’s Department of Atomic Energy and the US' National Science Foundation (NSF) on setting up Laser Interferometer Gravitational-wave Observatory (LIGO) in India, on the sidelines of the Nuclear Security Summit in Washington. The Union cabinet had said "LIGO-India will also bring considerable opportunities in cutting edge technology for the Indian industry" which will be responsible for the construction of the new observatory's 4-kilometer-long beam tubes.

Indian scientists at Raja Ramanna Centre for Advanced Technology (RRCAT) Indore have designed a special testing/prototype facility for receiving Advanced LIGO parts; have been training the teams that will install and commission the detector; and are currently cross-checking the IPR vacuum-system drawings against the Advanced LIGO detector drawings, to ensure a good fit and rapid installation for the third Advanced LIGO detector.

The world's smallest diode of a size of a single molecule, has been developed jointly by U.S. and Israeli researchers from the University of Georgia and Ben-Gurion University of the Negev (BGU). The study was published online in Nature Chemistry.

The discovery can lead to progress in the design and construction of nanoscale electronic elements that are at least 1,000 times smaller than current components.

News 7 - Low Cost Micro Solar Dome Surya Jyoti launched

Micro Solar

Union Minister for Science & Technology and Earth Sciences, Dr. Harsh Vardhan, launched the Low Cost and Environment-friendly solar lighting device, Surya Jyoti. The device has been developed under the aegis of the Department of Science & Technology.

It would prove to be a boon for the urban and rural households in the country that do not have reliable access to electricity. Photo-Voltaic Integrated Micro Solar Dome costs about Rs.1200 and the Non Photo-Voltaic version around Rs. 500.

News 8 - Gravity Gobbler ‘Black Hole’ weighing 17 billion Suns Found in Cosmic Backwater

Gravity Gobbler

The astronomers at National Aeronautics and Space Administration (NASA) discovered a super massive Black Hole in the center of a galaxy in a sparsely populated area of the universe.

The supersized black hole resides in the center of a massive elliptical galaxy, NGC 1600, located in a cosmic backwater, a small grouping of 20 or so galaxies, which weighs about 17 billion times the mass of Sun," said astronomer Chung-Pei Ma, head of the MASSIVE Survey.

Falcon 9 rocket

The SpaceX successfully landed Falcon 9 rocket on a drone ship at sea after being launched into space. This was the first time that the company succeeded in landing the rocket in Ocean.

This was the second time SpaceX successfully landed one of its rockets post-launch, the first time was on 21 December 2015, when the company's Falcon 9 rocket touched down at a ground-based landing site in Cape Canaveral, Florida, after putting a satellite into space.

News 10 - World's Thinnest Laptop Introduced by HR Inc. (Hewlett-Packard)

Thinnest Laptop

The American IT company HR Inc. (Hewlett-Packard) launched world thinnest laptop of 10.4 mm thickness, 13.3-inch full HD screen and weighs 2.45 pounds only. It has battery backup of 9 and a half hours. Surprisingly, the display isn't a touch-screen, and there's no option to get one.

News 11 - NASA’s Kepler Spacecraft goes into Emergency mode

Satellite Centre

NASA’s Kepler spacecraft has gone into emergency mode (EM). Emergency Mode is the lowest operational mode during the orbit.

Launched in March 2009, the spacecraft looks for Earth-like planets orbiting other stars. Since its launch, the mission has been highly successful. It has led to finding of more than 1,000 alien planets of which almost half are exo-planets to be ever discovered.

News 12 - Chinese researchers develop all-weather Solar Cell

all-weather Solar Cell

A group of researchers from the Ocean University of China and Yunnan Normal University have developed a new type of solar cell that can generate electricity during rain. The prototype solar cell uses "Graphene" which allows electrons to flow freely on its surface.

Rain water consists of bits of salt that separate into positive and negative ions. Graphene, on the solar panels, lets positive ions pair with negative electrons to produce electricity as the end product.
