Seems it only gets better. Exoplanet reseacrh is by far, the field I have the most interest in. <div class="Discussion_UserSignature"> <p><strong>My borrowed quote for the time being:</strong></p><p><em>There are three kinds of people in life.

I think what's most exciting to me is that I truly believe that in my lifetime, we will be detecting terrestrial exoplanets with regularity.<br /><br />One thing that has already proven out is that it would seem planetary systems are ubiquitous in the universe.<br /><br />I live for the day I read the headline that says "Oxygen and Water Bearing Planet Detected in Orbit Of...."<br /><br />I love this exoplanet stuff. <img src="/images/icons/smile.gif" /><br /><br /><br /><br /> <div class="Discussion_UserSignature"> <em>"2012..

You n me both.

Hot Jupiter and Tdwarfs are hero of the day.Tdwarfs are brown dwarfs,

That they are. Without hot jupiters, we'd probably still be trying to find extrasolar planets.<br /><br />What is meant by the term Tdwarf? <div class="Discussion_UserSignature"> <p><strong>My borrowed quote for the time being:</strong></p><p><em>There are three kinds of people in life.

Considering the number of hot Jupiters we've detected in close orbit to their host stars, I've always wondered if Mercury might not be the remnant of a hot Jupiter after its atmosphere boiled off.<br /><br />What got me thinking about it was that some of those planets are so close to their Sun that even Iron is in gaseous form.<br /><br />I know also that the Moon is receding from Earth and will continue to do so until it reaches a stable orbit.<br /><br />Putting 2 and 2 together and coming up with 5 most likely, I just wonder if Mercury might not have been a hot Jupiter in a closer orbit at one time. <div class="Discussion_UserSignature"> <em>"2012..

Good point, it may well have been. And probably not for that long relatively speaking since its had the crap battered out of it. <div class="Discussion_UserSignature"> <p><strong>My borrowed quote for the time being:</strong></p><p><em>There are three kinds of people in life.

Brown dwarfs are too small to count.We have so many dwarfs.Names depleted .So brown dwarf is t dwarf.

Thanks for that info. I was wondering what I missed on that one. <div class="Discussion_UserSignature"> <p><strong>My borrowed quote for the time being:</strong></p><p><em>There are three kinds of people in life.

<font color="yellow">I think what's most exciting to me is that I truly believe that in my lifetime, we will be detecting terrestrial exoplanets with regularity.</font><br /><br />If Corot makes it into orbit in november and achieves the photometric precision that it's designed to achieve then there's a very good chance that by christmas 2007 they'll have discovered a number of transiting hot terrestrial planets (depending of course on how common they actually are, though there are predictions that they're quite a bit more common than the hot gas giants), and that HARPS will actually be able to measure radial velocities for them so that we can really say what their densities are and determine if they're terrestrial planets, or ocean planets or gas giants or what. <br /><br />And if Kepler manages to launch in 2008 and achieves the precision that they're supposed to achieve, then they're predicted to find 50-100 Earth-like transiting planets (i.e. planets the size of the Earth, orbiting 1AU from sun-like stars) though we wouldn't know about those discoveries until 2012 or 2013.<br /><br />This is such a great time to be alive I think <img src="/images/icons/smile.gif" />! <div class="Discussion_UserSignature"> </div>
