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

Concept: Coronal Mass Ejections (CMEs) are massive bursts of solar wind and magnetic fields rising above the solar corona. Tracking the exact origins where a CME generates its initial shockwave is vital for space weather forecasting, as these shocks can disrupt satellite communications, GPS systems, and power grids on Earth.

Step 1: Identify the specialized scientific body. The Indian Institute of Astrophysics (IIA), an autonomous research institute under the Department of Science and Technology, specializes in solar physics, stellar dynamics, and astronomical instrumentation.

Step 2: Analyze the research breakthrough. Leveraging advanced data from space-borne coronagraphs and ground observatories, researchers at IIA successfully mapped the precise acceleration regions where solar plasma transformations create an initial shock wave, marking a significant milestone in observational astrophysics.

Step 3: Eliminate alternative institutions. The Vikram Sarabhai Space Centre (VSSC) focuses primarily on launch vehicle development (like PSLV/GSLV); IISST is a space university. While TIFR conducts broad fundamental physics research, the premier center dedicated directly to solar observational physics of this nature is the Indian Institute of Astrophysics.
