Have astronomers using Kepler discovered the first exomoon?

The uncertainty of science: Using data from Kepler astronomers think they have spotted the first exomoon, orbiting a star 4,000 light years away.

They think it might be the size of Neptune, and orbits a planet about ten times more massive than Jupiter.

All this is unconfirmed, however, especially because their conclusions are based on data from only three transits. They plan to use the Hubble Space Telescope to do more observations and hopefully confirm the discovery.

    A star 4000 miles away … you might want to proofread this. Light years perhaps?

  • mike shupp: Error fixed. When you type as much as I do, errors like this happen. I don’t have a staff here (except my readers) to proof read me.

    Oh yeah. Actually I didn’t think it was your error, just a byproduct of scanning a document or web page elsewhere on which somebody else had goofed. Glad to be of service!

    They call it “Nept-moon” I shall call it Yavin 4.
