Correct Option: D
Explanation:

Astrobiology encompasses the study of the origin and evolution of life on Earth, the search for life beyond Earth, and the understanding of the conditions necessary for life to exist.

Which Indian space agency is responsible for astrobiology research?

  1. Indian Space Research Organisation (ISRO)

  2. National Aeronautics and Space Administration (NASA)

  3. European Space Agency (ESA)

  4. Japan Aerospace Exploration Agency (JAXA)


Correct Option: A
Explanation:

The Indian Space Research Organisation (ISRO) is responsible for astrobiology research in India.

What is the name of ISRO's dedicated astrobiology mission?

  1. Mangalyaan

  2. Chandrayaan-2

  3. Astrosat

  4. NISAR


Correct Option: C
Explanation:

Astrosat is ISRO's dedicated astrobiology mission, launched in 2015.

What is the primary objective of the Astrosat mission?

  1. To study the origin and evolution of galaxies

  2. To search for exoplanets

  3. To study the properties of black holes and neutron stars

  4. To study the cosmic microwave background


Correct Option: B
Explanation:

The primary objective of the Astrosat mission is to search for exoplanets, or planets orbiting stars other than the Sun.

Which instrument on Astrosat is specifically designed for exoplanet detection?

  1. Ultraviolet Imaging Telescope (UVIT)

  2. Large Area X-ray Proportional Counter (LAXPC)

  3. Scanning Sky Monitor (SSM)

  4. Cadmium Zinc Telluride Imager (CZTI)


Correct Option: A
Explanation:

The Ultraviolet Imaging Telescope (UVIT) on Astrosat is specifically designed for exoplanet detection.

What is the significance of UVIT in exoplanet detection?

  1. It can detect exoplanets directly

  2. It can detect exoplanets indirectly by observing their transits

  3. It can study the atmospheres of exoplanets

  4. It can measure the masses of exoplanets


Correct Option: B
Explanation:

UVIT can detect exoplanets indirectly by observing their transits, which occur when an exoplanet passes in front of its host star and blocks some of the star's light.

How many exoplanets has Astrosat discovered to date?

  1. 0

  2. 1

  3. 5

  4. 10


Correct Option: B
Explanation:

As of 2023, Astrosat has discovered one exoplanet, named HAT-P-7b.

What is the name of the first exoplanet discovered by Astrosat?

  1. HAT-P-7b

  2. Kepler-452b

  3. TRAPPIST-1e

  4. Proxima Centauri b


Correct Option: A
Explanation:

The first exoplanet discovered by Astrosat is HAT-P-7b.

What is the significance of HAT-P-7b's discovery?

  1. It is the first exoplanet discovered by an Indian space agency

  2. It is the first exoplanet discovered in the habitable zone of its host star

  3. It is the first exoplanet discovered with a mass similar to Earth's

  4. It is the first exoplanet discovered with a thick atmosphere


Correct Option: A
Explanation:

The significance of HAT-P-7b's discovery lies in the fact that it is the first exoplanet discovered by an Indian space agency.

What are the future plans for astrobiology research in India?

  1. To launch more dedicated astrobiology missions

  2. To collaborate with international space agencies on astrobiology projects

  3. To establish an astrobiology research center

  4. All of the above


Correct Option: D
Explanation:

India plans to launch more dedicated astrobiology missions, collaborate with international space agencies on astrobiology projects, and establish an astrobiology research center.

How does astrobiology contribute to our understanding of the universe?

  1. It helps us understand the origin and evolution of life

  2. It helps us search for life beyond Earth

  3. It helps us understand the conditions necessary for life to exist

  4. All of the above


Correct Option: D
Explanation:

Astrobiology contributes to our understanding of the universe by helping us understand the origin and evolution of life, search for life beyond Earth, and understand the conditions necessary for life to exist.

Why is the search for life beyond Earth important?

  1. It can help us understand the diversity of life in the universe

  2. It can help us understand the conditions necessary for life to exist

  3. It can help us understand the origin and evolution of life

  4. All of the above


Correct Option: D
Explanation:

The search for life beyond Earth is important because it can help us understand the diversity of life in the universe, the conditions necessary for life to exist, and the origin and evolution of life.

What are some of the challenges in searching for life beyond Earth?

  1. The vastness of space
