Exoplanetary Science covers the detection, characterization, and study of planets orbiting stars other than our Sun. You'll learn about various detection methods like transit photometry and radial velocity, planetary formation theories, and the potential for habitable worlds. The course delves into planetary atmospheres, internal structures, and the search for biosignatures on distant worlds.
Exoplanetary Science can be challenging, especially if you're not strong in physics and math. It involves complex concepts from astrophysics, planetary science, and data analysis. That said, if you're genuinely interested in alien worlds and space exploration, the coolness factor can make it feel less daunting. Most students find it manageable with consistent effort and a solid foundation in basic astronomy.

Science Communicator: Translate complex exoplanetary science concepts for the general public. You might work for planetariums, science museums, or media outlets, creating engaging content about the latest exoplanet discoveries.
Aerospace Engineer: Design and develop instruments for exoplanet detection and characterization. You could work on next-generation space telescopes or contribute to the development of future exoplanet exploration missions.
How many exoplanets have been discovered so far? As of 2023, over 5,000 exoplanets have been confirmed, with thousands more candidates awaiting verification. This number is constantly growing as detection methods improve and more data is analyzed.
Can we actually see exoplanets directly? While most exoplanets are detected indirectly, a few have been directly imaged using advanced telescopes and imaging techniques. These are typically young, massive planets orbiting far from their host stars.
What's the most Earth-like exoplanet we've found? Several exoplanets have been identified as potentially habitable, but Kepler-452b is often cited as one of the most Earth-like. It orbits a Sun-like star and is located in the habitable zone, though it's about 60% larger than Earth.
