At the time of the 1997 flyby, about 124 miles (200 kilometers) above Europa’s surface, the Galileo team didn’t suspect the spacecraft might be grazing a plume erupting from the icy moon.

This was also Galileo's closest approach to Europa, when it came to within 206km and flew near the Pwyll Crater region. During this pass, the spacecraft's magnetometer measured significant changes ...

Now, researchers report in a new study that NASA's Galileo Jupiter probe, which orbited the planet from 1995 to 2003, also detected a likely Europa plume, during a close flyby of the icy moon in 1997.

Jupiter’s icy moon Europa may have been spitting into space for at least 20 years. Analyzing old Galileo mission data suggests that the NASA spacecraft flew through a plume of water vapor from ...

The Galileo data were collected during a Europa flyby in 1997 at an altitude of less than 250 miles. The spacecraft's magnetometer, used to detect and measure magnetic field strength, and its ...

Clues hidden in data from NASA’s Galileo spacecraft—which explored the Jupiter system between 1995 and 2003—suggest very strongly that the icy moon Europa is venting water into space ...

Jupiter's moon Europa probably has a vast ocean under its surface, and it may blast plumes of water out into space. It turns out that Galileo, a probe that visited Jupiter in the 1990s, probably ...

While six spacecraft have visited and imaged Europa since it became one of the first moons found beyond Earth, the best evidence of a subsurface ocean was gathered by NASA’s Galileo spacecraft ...

The Galileo mission has given astronomers an astonishing wealth of discoveries to ponder, but none, perhaps, as dramatic as the clear indication that Europa, the smallest of the four Galilean ...

Galileo was sent plunging into Jupiter's atmosphere in 2003 to prevent a possible impact with Europa. A few years back, NASA's Cassini spacecraft flew through a similar plume emanating from Saturn ...

While six spacecraft have visited and imaged Europa since it became one of the first moons found beyond Earth, the best evidence of a subsurface ocean was gathered by NASA’s Galileo spacecraft ...

A NASA mission to explore a Jupiter moon believed to be one of our galaxy's most promising locations to search for life-supporting conditions is at long last underway. The Europa Clipper launched ...
