  What are Exoplanets? •• Planets that orbit stars outside our solar system • • First confirmed discovery in 1992
• 3.
  Detection Methods • •Transit Method – Observing dips in a star’s brightness • • Radial Velocity – Detecting wobble in star movement • • Direct Imaging and Gravitational Microlensing

• 5.
  Prominent Discoveries • •Kepler-22b, Proxima Centauri b, TRAPPIST-1 system • • Thousands of candidates identified by Kepler and TESS missions
• 6.
  Search for Life •• Astrobiology studies life’s potential elsewhere • • Key factors: Atmosphere, temperature, presence of water
• 7.
  Future Prospects • •James Webb Space Telescope and upcoming missions • • Goal: Find biosignatures and signs of habitability
