Join us as we explore the cutting-edge techniques astronomers use to discover thousands of exoplanets orbiting distant stars and how the search has now evolved toward finding signs of life itself.
We dive into the transit method, radial velocity, direct imaging, and gravitational microlensing that have revealed everything from scorching hot Jupiters to potentially habitable super-Earths. Next we explain how next-generation telescopes like the James Webb Space Telescope and future giants such as the Extremely Large Telescope analyze exoplanet atmospheres for biosignatures: oxygen, methane, water vapor, and technosignatures that could betray the presence of biology or civilization.
From the first exoplanet discoveries in the 1990s to today’s hunt for a true “Earth 2.0,” this video reveals the science, the instruments, and the tantalizing clues that might finally answer whether we are alone in the universe.
