Which of the following statement is/are True about India's AstroSat?

1. In November 2023, India's AstroSat space telescope has detected over 600 Gamma-
Ray Burst (GRB), marking the death of a massive star or merging of neutron stars.

2. The detection is a significant milestone, demonstrating the continued undiminished
performance of the Cadmium Zinc Telluride Imager (CZTI) eight years after its launch.

Correct option is B

Statement 1: In November 2023, AstroSat detected over 600 Gamma-Ray Bursts, extremely energetic cosmic events resulting from stellar collapses or neutron star mergers.

Statement 2: The continued performance of the Cadmium Zinc Telluride Imager (CZTI), even after 8 years in orbit, marks a significant milestone in India's space science capabilities.

• AstroSat observes the universe in X-ray, ultraviolet, and visible light, making it a multi-wavelength observatory.

• It was launched on 28 September 2015 aboard PSLV-C30 from Sriharikota.

• GRBs (Gamma-Ray Bursts) are the brightest electromagnetic events known to occur in the universe.

• AstroSat is operated by the Indian Space Research Organisation (ISRO) and has been extended beyond its planned 5-year lifespan.

• India became one of the few countries to have a space-based observatory alongside the US, Russia, and Europe.
