Spaceflight Now | Breaking News | Kepler finds 11 new solar systems beyond our own

Cool on this part "One of the stars, named Kepler-33, has five planets slightly larger than Earth orbiting closer than Mercury to the sun. "

Space give us one marvel after the other.

And if I'm not mistaken, considering Kepler need 3 "positive" detections of a planet orbiting a sun before confirming it, the announcement of a few rocky planets in the habitable zone (goldilocks) around suns similar/same category to ours is like...NOW.

But are they really planets? (According to the definition that got Pluto kicked out)

If they're orbiting closer than Mercury, and they are still in the Goldilocks zone, that would mean the star is much smaller.

Actually Habitable zones are not stable. Over the life of a star, the nature of the zone moves and changes. Definitions of Habitable zones are used in the Search for Extra-Terrestrial Intelligence.
