Regarding so-called "exospots", they're just called Starspots http://en.wikipedia.org/wiki/Starspot

"Observed starspots are in general much larger than those on the Sun: up to about 30% of the stellar surface may be covered, corresponding to sizes 100 times greater than those on the Sun."

Man, that would be nice to see in SE!

And, apparently, we can map sunspots on eclipsing binaries... http://star-www.st-and.ac.uk/~acc4/coolpages/movies.html

There was a story recently about a Kepler planet that was not found by the transit method, but rather by relativistic effects, the first such discovery. I forgot to post about it. Kepler-76 b.

Wait, what? It was discovered by the effect of relativistic beaming? That's insane! wacko

Absolutely is, hopefully not was! Even if it has already accomplished its objectives and lived its scheduled lifetime. smile

I really hope they can spin it up or take measurements with only two operational wheels. But that makes me wonder. Why are the wheels failing? Was it a design flaw or have they exceeded their lifetimes?

Boo for the manufacturers making the lifetime too short. If only replacing sattelite parts in space was easy, see Hubble for what I mean (and that took months of planning and Earthside practice).

...so you think that they can just wave their magic tools and make parts that last forever? It's a mechanical part that is moving non-stop for years in a harsh environment, it's going to wear out eventually.

No, just wish it would last longer and I'm sure we all wish that.

Of course we do, but that's no reason to accuse the manufacturers of intentionally creating short-lived parts.

A new proposal for use of the Spitzer telescope on an extended mission would have it look for planets, including potentially habitable ones, down to Mars-sized, around brown dwarfs.
