[E] Gran Telescopio Canarias

Answer: A. James Webb Space Telescope

Explanation:

Nasa has pushed the planned launch of its $8.8 billion James Webb Space Telescope from October 2018 to the spring of 2019, citing spacecraft-integration issues. The successor to the famed Hubble Space Telescope, Webb will now launch between March and June 2019 from French Guiana, following a schedule assessment of the remaining integration and test activities, Nasa said.

4. USA has agreed to co-operate with which country to build moon's first space station?
[A] China
[B] India
[C] Russia
[D] Japan
[E] UK

Answer: C. Russia

Explanation:

Russia and the United States have agreed to cooperate on a NASA-led programme to build the first lunar space station, part of a long-term project to send humans to Mars. The US space agency said earlier this year that it was exploring a programme called the Deep Space Gateway, a multi-stage project to push further into the solar system. Russia and the United States also discussed using Moscow’s Proton-M and Angara rockets to help create the infrastructure of the lunar spaceport, the statement said, adding that the main works were scheduled to begin in the mid-2020s.
5. Virgo observatory is located in which country?
[A] India
[B] USA
[C] France
[D] Brazil
[E] Italy

Answer: E. Italy

Explanation:

Virgo observatory is located in Santo Stefano a Macerata, Cascina, Italy. ​On September 27, 2017, scientists from the Laser Interferometer Gravitational-wave Observatory (LIGO) and Virgo observatory said that they successfully detected on August 14 the fourth gravitational wave, ripples in space and time, from the merger of two massive black holes. The first two detections were made in September and December 2015 in quick succession and the third one came on January 4, 2017. LIGO-Virgo collaboration includes more than a thousand scientists from different countries, setting a great example in international scientific cooperation.
6.

Consider the following statements: (1) Mars Orbiter Mission on September 25, 2017, completed three years in Mars orbit.



(2) It was launched on 5 November 2012 by the Indian Space Research Organisation (ISRO).



(3)  It is India's first interplanetary mission and ISRO has also become the fourth space agency to reach Mars, after the Soviet space program, NASA, and the European Space Agency.



Which of the above statement/s is/are true?


[A] Only 2 and 3
[B] Only 1
[C] Only 3
[D] Only 1 and 3
[E] All of the above

Answer: D. Only 1 and 3

Explanation:

ISRO's low-cost Mars Orbiter Mission has completed 3 years in its Martian orbit.The Rs. 450 cr MOM mission aims at studying Martian surface & mineral composition. It will scan its atmosphere for methane which is an indicator of life on Mars.ISRO had launched the spacecraft from Sriharikota in Andhra Pradesh on November 5, 2013. Scientific analysis of data received from the spacecraft is in progress.
7. The Optical polarisation phenomenon was discovered by _____.
[A] Krishnaswami Alladi
[B] S. Krishnaswami Aiyangar
[C] Madhavan Ayyappath
[D] Subrahmanyan Chandrasekhar
[E] Kodandera M. Cariappa

Answer: D. Subrahmanyan Chandrasekhar

Explanation:

The Optical polarisation phenomenon was discovered by  Subrahmanyan Chandrasekhar in 1946.  Over 70 years after its discovery, scientists from the University of New South Wales (UNSW) in Australia and University College London in the UK detected it using a

highly sensitive piece of equipment to detect the polarised light from Regulus, one of the brightest stars in the night sky.The equipment provided unprecedented insights into the star, which is in the constellation Leo, allowing the scientists to determine its rate of spinning and the orientation in space of the star's spin axis. Optical polarisation is a measure of the orientation of the oscillations of a light beam to its direction of travel.

8. The Department of Science and Technology on September 21, 2017 has started the process of building a _____ computer.
[A] Quantum
[B] Chemical
[C] Biological
[D] Organic
[E] DNA

Answer: A. Quantum

Explanation:

The Department of Science and Technology is planning to fund a project to develop quantum computers.A quantum computer, still largely a theoretical entity, employs the principles of quantum mechanics to store information in ‘qubits’ instead of the typical ‘bits’ of 1 and 0.Canada’s D-Wave Systems, is a pioneer in quantum computers.
9. The Indian government on September 20, 2017 announced to build a lab on boat on the river______.
[A] Ganga
[B] Brahmaputra 
[C] Chenab
[D] Sabarmati
[E] None of the above

Answer: B. Brahmaputra 

Explanation:

A new project of the Department of Biotechnology aims at starting a lab on boat on Bramhaputra river for biological analysis of the river system. The ambitious project also proposes to have multiple mobile laboratories on the river and its tributaries along with providing access to local research institutions, officials said.The first laboratory under the Bramhaputra Biodiversity Biology Boat (B4) initiative will cover Pasighat, Dibrugarh, Neemati, Tejpur and Guwahati in Assam.
10. As per a report published by ___ and _____, aerosols have been detected over Asia.
___ और _____ द्वारा प्रकाशित एक रिपोर्ट के अनुसार, एशिया में एयरोसोल की उपस्थिति का पता लगाया गया है।
[A] ISRO, NASA
[B] JAXA, CNSA
[C] AEM, ISA
[D] ROSCOSMOS, CRTS
[E] UAESA, CNES

Answer: A. ISRO, NASA

Explanation:

A joint study by the Indian Space Research Organisation (ISRO) and National Aeronautics and Space Administration (NASA) of the US, which had commenced after satellite images showed the presence of an aerosol layer over the Asia region, has confirmed the same and has also found the presence of nitrate, which is a new finding.  Aerosol, the sub-micron size particles suspended in air are produced from a variety of man-made and natural processes such as vehicle exhaust, waste-burning, wind blown dust, volcanic eruptions et al, are mostly restricted to the first few ​kilometres from the surface of Earth's atmosphere—Upper Troposphere and Lower Stratosphere (UTLS).
