In September 2014, NASA reported that HAT-P-11b is the first Neptune-sized exoplanet known to have a relatively cloud-free atmosphere and, as well, the first time molecules of any kind have been found, specifically water vapor, on such a relatively small exoplanet.
PSR J1719−1438 b is an extrasolar planet that was discovered on August 25, 2011, in orbit around PSR J1719−1438, a millisecond pulsar.The pulsar planet is most likely composed largely of crystalline carbon but with a density far greater than diamond.
Motion interpolation of seven images of the HR 8799 system taken from the W. M. Keck Observatory over seven years, featuring four exoplanets. This is a list of extrasolar planets that have been directly observed, sorted by observed separations. This method works best for young planets that emit infrared light and are far from the glare of the star.

They recreated Neptune's conditions at Stanford's SLAC Laboratory and successfully observed the formation of diamond rain, thanks to the help of some very powerful lasers. Scientists recreate ...
This is the first time the atmosphere of a super-Earth exoplanet was analyzed successfully. [31] [32] In November 2017, it was announced that infrared observations with the Spitzer Space Telescope indicated the presence of a global lava ocean obscured by an atmosphere with a pressure of about 1.4 bar, slightly thicker than that of Earth.
The exoplanet closely orbits its host star, and the intense heat and radiation received from that sun-like star — more than 4,000 times the amount of radiation that Earth gets from our sun ...
The first exoplanet atmosphere ever observed was that of HD 209458b, a Hot Jupiter orbiting a G-type star similar in size and mass to our sun. Its atmosphere was discovered by spectroscopy; as the planet transited its star, its atmosphere absorbed some of the star's light according to the detectable absorption spectrum of sodium in the planet's atmosphere.
