Question

Astronomers from which institution discovered the origin of a Coronal Mass Ejection (CME) shock for the first time?

• A. Vikram Sarabhai Space Centre
• B. Indian Space Science & Technology Organisation
• C. Tata Institute of Fundamental Research
• D. Indian Institute of Astrophysics

Hint:

For questions regarding specialized deep-space observations, stellar anomalies, or solar corona discoveries, the Indian Institute of Astrophysics (IIA) based in Bengaluru is typically the lead institution.

Answer 1

The Correct Option is D

Step 1: Understand the question.
We need the institution whose astronomers first found the origin of a Coronal Mass Ejection (CME) shock.

Step 2: Identify it.
The Indian Institute of Astrophysics (IIA) made this discovery.

Step 3: Why IIA.
The IIA, under the Department of Science and Technology, specialises in solar physics. Using coronagraph and observatory data, its team mapped where the shock wave first forms.

Step 4: Rule out others.
VSSC focuses on launch vehicles and TIFR on broad physics, but the leading solar observational centre here is the IIA.

Step 5: Conclude.
The institution is the Indian Institute of Astrophysics.

Answer: Indian Institute of Astrophysics
