Kepler was one of the most successful exoplanet-hunting missions so far. It discovered 2,600 confirmed exoplanets—almost half ...

Gravitational microlensing occurs when one star passes directly in front of a background star ... three of the smallest rocky exoplanets yet detected—each no larger than Mars—closely orbit ...

Finding this particular exoplanet was no easy task; it required more work than just pointing one telescope to the sky and noticing the novel celestial body. Instead, it required analyzing more than 20 ...

These exoplanets (planets orbiting a star other than our sun) orbit close to red dwarf stars that are smaller and cooler than the sun, and which make up over 75% of the 200 billion stars in the ...

Though no exoplanet has been found to precisely twin ... they tested each telescope's instruments' abilities to differentiate universal background noise from the planetary noise they aimed to ...
