Don't know if someone already referred to this in another topic and I didn't know where to put it so...

Well - the key announcements in this field have been the detection of smaller and smaller planets. First super-jupiters, then jupiter sized, then uranus sized....there's not much left really
 Perhaps better spectra extracted from them? Doug |

QUOTE (djellison @ Jan 24 2006, 01:22 PM) Perhaps better spectra extracted from them?  I didn't think they could get direct spectra yet? In any case my bets are on a Jupiter range planet or two with orbits similar to our own Jupiter. As far as I can recall such a configuration should make an earth sized planet in the goldilocks zone much more likely. |

Not direct spectra, but they can look at a spectra during and after transits and do maths on those to pull something out of the actual planet.

I thought that some kind of spectra (IR?) was obtained from one of the exoplanets that transits its star - I can't remember it's alpha-numeric designation right now...

Tomorrow we'll see... http://television.esa.int/default.cfm Yes, I had already started a thread on this under EVA, with SpaceRef and ESA TV links. I wasn't sure the best spot either. Perhaps there could be a forum or subforum just for extrasolar planets Doug? Perhaps also under 'Beyond'? http://www.unmannedspaceflight.com/index.php?showtopic=2100 Someone in the Space.com forum said he had heard some other info that it involves a smaller planet(s), closer to Earth-size, but don't know how accurate that is yet. |

Sorry Paul but I haven't seen your post...Maybe Doug can merge both into one new in 'Beyond' as you said... Earth-sized planet if it is that that would be Major indeed... -------------------- "Ride, boldly ride," The shade replied, "If you seek for Eldorado!"

I'm pretty sure it is the one noticed by the Slacker Astronomers in the AAS meeting:
QUOTE A funny thing happened to me on my way to the forum. A poster just 2 slots down from my own had a big sign and red cross on it. The sign read: "This poster has been withdrawn due to anm embargo and will appear in the January 26 issue of nature." (paraphrase) From the title (the only other thing we could read), it was about the discovery of a low mass extrasolar planet. So far most planets have been larger than Earth. Is this the first Earth-sized planet? We'll find out in about 2 weeks when Nature releases its grip.

Earth-sized planet if it is that that would be Major indeed... That's fine, as long as it gets discussed! I like the merge idea. In the meantime, I found another reference to a possible smaller (lower mass) planet: http://sa-blog.livejournal.com/2804.html Exciting if so, but will be interesting I'm sure anyway, whatever the news is. Addendum: And now just as I'm posting this, Jyril's post showed up with the same link, oh well.

It's a 5 earth-mass planet 25,000 light years away?
