New Horizons Mission Finds Evidence of Subsurface Ocean on Pluto
The New Horizons mission, launched by NASA in 2006, has been making groundbreaking discoveries in the far reaches of our solar system. One of the most exciting findings so far is evidence of a subsurface ocean on Pluto, which could have significant implications for the potential for extraterrestrial life.
The evidence for the subsurface ocean comes from observations of the Sputnik Planitia region on Pluto's surface, which appears to be a large basin filled with ice. However, the basin is not located in the expected position based on Pluto's gravitational field, suggesting that there may be a large mass beneath the surface affecting the planet's rotation. Scientists believe that this mass may be an ocean or a giant blob of very cold, dense material.
If the mass is indeed an ocean, it could be home to microbial life. Despite being located so far from the sun, the subsurface ocean would be kept warm by the heat generated by the decay of radioactive isotopes in the planet's core. Additionally, the ocean would be protected from the harsh radiation environment of space by the thick layer of ice above it.
The discovery of a subsurface ocean on Pluto also raises questions about the potential for similar bodies of water on other icy worlds in the outer solar system. As we continue to explore these distant regions, we may discover even more evidence of subsurface oceans and the potential for extraterrestrial life.
