First" Exomoon" Perhaps ?

[John]

Interesting finding by the Kepler Space Telescope - a possible moon that is as large as Neptune and orbiting a massive exoplanet orbiting a star 4000 light years away  !

Early days though, more confirming observations needed ....

Considering the number of moons so far discovered in our solar system, who knows how many moons there are out there!  

We will probably get used to news about exomoons and exoplanets in near future with the new coming telescopes.

Right now, it is an amazing news though! As far as this type of research (astronomy) concerns, I think we are lucky to live in an era with an almost exponential increase in knowledge and discoveries.
