Searching for distant and wandering worlds
In a global exoplanet observation experiment, NASA’s Kepler K2 mission and Earth-based observatories on six continents hope to survey millions of stars toward the centre of our Milky Way galaxy. Using a technique called gravitational microlensing, scientists will hunt for exoplanets that orbit far from their host star and for free-floating exoplanets that wander between the stars.
