Recent discoveries by the James Webb Space Telescope (JWST) have highlighted planets that may be entirely covered by water.
These missions collect "bathymetric" data (sea depth and contours) and meteorological info. This is critical for undersea warfare , as temperature and salinity data help submarine commanders elude detection and improve sonar performance. Distant Ocean
A planet 100 light-years away that is 70% larger than Earth and may be a complete ocean world with no landmasses. Recent discoveries by the James Webb Space Telescope
This is the most famous candidate. Scientists at the University of Cambridge have detected methane and carbon dioxide in its atmosphere, suggesting a hydrogen-rich environment and a potentially massive liquid ocean. A planet 100 light-years away that is 70%
In a terrestrial context, "distant-ocean" refers to deep-sea maritime operations, particularly those by the People's Liberation Army Navy (PLAN) and civilian researchers.
"Distant ocean" most often refers to two very different things: far outside our solar system, or specialized maritime survey activities conducted by nations like China in deep-sea regions. 1. Astronomical "Ocean Worlds" (Exoplanets)
Astronomers may have found traces of dimethyl sulfide (DMS) on K2-18b. On Earth, this molecule is only produced by life, specifically marine phytoplankton. However, researchers remain cautious as unknown chemical processes could also explain it. Other Candidates:
