Missions like Kepler, TESS and ground-based observatories have identified about 5788 confirmed exoplanets (as of 27 Nov 2024)...

The vastness and beauty of the night sky have captivated humanity for centuries. The countless stars visible to the naked eye represent only a small fraction of the greater cosmic puzzle. Our eyes are sensitive only to those astronomical objects that emit maximum radiation in the optical waveband (λ = 350-750 nm).
