LOS ANGELES, Dec. 17 (Xinhua) — A NASA study of exoplanets found that 17 exoplanets may have oceans containing liquid water. It is an important component for living things. Under the ice crust
NASA identifies extrasolar planets It is a world outside our solar system. Water from these oceans may occasionally erupt through the ice in the form of geysers or natural geysers.
A team of scientists has calculated the amount of geyser activity on the planet for the first time. and identified two exoplanets close enough to allow these eruption signals to be observed with telescopes.
“Our analysis suggests that 17 of these worlds may have icy surfaces,” said Lynney Quick, an expert at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. But it receives enough internal heat from the decay of radioactive elements and tidal force, which causes the phenomenon of tides and tides from the host star. to preserve the inner ocean
Quick added that all of the planets in our study may still display icy volcanic activity. (cryovolcanic) in the form of a cloud of smoke similar to a geyser. This is due to the amount of internal heat they are exposed to.
