Infographic: Profile of planet 51 Pegasi b

The first exoplanet discovered around a sun-like star, 51 Pegasi b made us question what we knew of our universe and launched the search for new worlds.

Astronomers have discovered one of the most distant planets known, a gas giant about 13,000 light-years from Earth, called OGLE-2014-BLG-0124L. The planet was discovered using a technique called microlensing, and the help of NASA's Spitzer Space Telescope and the Optical Gravitational Lensing Experiment, or OGLE. In this artist's illustration, planets discovered with microlensing are shown in yellow. The farthest lies in the center of our galaxy, 25,000 light-years away.

Astronomers were elated to find clear skies on a Neptune-size planet called HAT-P-11b, as illustrated here. Without clouds to block their view, they were able to identify water vapor molecules in the planet's atmosphere. The blue rim of the planet in this image is due to scattered light, while the orange rim on the part of the planet in front of the star indicates the region where water vapor was detected.

We now believe there is at least one planet for every star in our galaxy. This could mean as many as 100 to 400 BILLION planets in our galaxy alone. This major finding from the Kepler mission, launched in 2009, reveals a crowded galaxy and the sheer magnitude of potential discoveries: strange worlds we never thought could exist, and maybe one day, a world like our own.
