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.
This list of exoplanets discovered in 2025 is a list of confirmed exoplanets that were first reported in 2025. For exoplanets detected only by radial velocity , the listed value for mass is a lower limit.
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.
While we've yet to fully explore Neptune and its fellow gas giants, scientists have a lot of theories about them based on the info we know. For instance, they believe that it rains diamonds on ...
Hot atmospheres could have iron rain, [107] molten-glass rain, [108] and rain made from rocky minerals such as enstatite, corundum, spinel, and wollastonite. [109] Deep in the atmospheres of gas giants, it could rain diamonds [ 110 ] and helium containing dissolved neon.
2MASS J04414489+2301513 b is listed as the youngest planet in the NASA Exoplanet Archive, at an age of 1 Myr, [1] but fails the mass ratio criterion of the IAU working definition of an exoplanet; the mass ratio with the primary is larger than the L4/L5 limit of stability ≈ 1/25 [59] and 'more likely to have been produced by cloud core ...
The IAU's names for exoplanets – and on most occasions their host stars – are chosen by the Executive Committee Working Group (ECWG) on Public Naming of Planets and Planetary Satellites, a group working parallel with the Working Group on Star Names (WGSN). [1] Proper names of stars chosen by the ECWG are explicitly recognised by the WGSN. [1]
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 ...
