NASA's Europa mission has been in the spotlight for quite some time now, especially after the space agency started to share the observations being made on the Jupiter's weird moon. Now, NASA said that it has a big announcement to make about Europa.

NASA recently gave a hint that it has discovered an unusually and surprising activity on the surface of Europa, Jupiter's moon, that has always been the center of discussion when it comes to alien life. However, NASA's announcement may not have anything to do with aliens on Europa at all.

The American space agency is scheduled to conduct a press conference on Sept. 26, Monday, to make the big announcement about Jupiter's icy moon. The findings that will be shared during the meeting are based on the photographs captured by the Hubble Space Telescope.

While UFO enthusiasts and alien hunters must have become excited upon the announcement that NASA will soon share the surprising finding, the space agency did not take even a minute to tweet that the information has nothing to do with the aliens.

Any announcement about Europa's inhabitant life would not have been a possibility in any case, since it is not possible for the Hubble Space Telescope to seek clear evidence of extraterrestrial life. Instead, NASA is expected to share key findings about the presence of subsurface water on the icy cold moon, which makes it a potentially habitable object in space.

The teleconference will be conducted by a team of scientists involved in NASA's Europa mission, including Jennifer Wiseman or NASA's Goddard Space Flight Center and Paul Hertz

Alien hunters are not the only ones excited about finding crucial evidence of life on the surface of Europa, but NASA itself believes that it may be true. In fact in 2015, NASA has announced that with abundant amount of salts, rocky core and energy generated through tidal heat, Europa is one of the best celestial body to observe when it comes to finding extraterrestrial life.
