Three Suns in the Sunset...

The latest extrasolar planet to be announced is another "hot jupiter", but this time it's in a triple star system about 149 light years away...
"The fact that a planet can even exist in a multiple-star system is amazing in itself," Konacki said For one thing, the planet has to contend with the gravitational pull of three other bodies [the suns]. For another thing, the theories and models of solar-system formation suggest that planets are very unlikely to form in such environments.
Time to get back to the planetary formation drawing boards.



For recent SF involving hot jupiters, may I direct your attention towards Brenda Cooper and Larry Niven's collaboration Building Harlequin's Moon. It's a rather interesting tale of terraforming in a very hostile solar system...

I heard this on Today, yesterday, full of bemused comments about the planet defying the known laws of physics because it "simply shouldn't be there."

BTW, where did you get the image? Last time I saw it was on the cover of Eric Brown's The Fall of Tartarus.

I found it on the Wikipedia hot jupiter entry. Apparently it's a freely available NASA image...

The back cover credit says 'Illustration by kind permission of NASA and the Hubble Heritage Team'. Looks great... almost makes me want to read it!
