GS Paper 3 (Science and Technology): space-based astronomy has become a key area of global scientific competition. Wide-field survey telescopes like Roman generate huge datasets on dark energy and exoplanets, which links to India's own space science missions such as AstroSat and its push for open data and international collaboration. The way forward is to build indigenous capacity in space instruments and data analysis while joining global missions.

উত্তর: A — Correct: 100 times — Roman's wide field of view is about 100 times that of Hubble's infrared camera. • 10 times — wrong: 10 times understates the gain; the figure is about 100 times. • 50 times — wrong: 50 times is too low; the figure is about 100 times. • 500 times — wrong: 500 times is an overstatement; the figure is about 100 times.
