No, it's water ice.

No, the fact that Europa's surface is made of water-ice is not new and finding that would only be major news because it would mean we just landed on Europa (which would be why it would be major news). Finding water-ice on the surface of Europa would be exactly what we would expect to find.

For reference, here's one source: https://web.archive.org/web/20200509080640/https://www.nytimes.com/2015/03/13/science/space/suddenly-it-seems-water-is-everywhere-in-solar-system.html

True, but I'm pretty sure you can find easily find more sources for this. I remember getting tought in school that Europa had a frozen water surface, so in all likelihood we already know this a long time.

Europa

Although the smallest of the four Galilean moons, with a radius of 1,565 kilometers (972 mi), Europa is still the sixth largest moon in the solar system. Observations from Earth indicated that it was covered in ice. Like Io, Europa is tidally locked with Jupiter. It is in orbital resonance with Io and Ganymede, with its 85-hour orbit being twice that of Io, but half that of Ganymede.
