I had thought that only massive objects of stellar size provided enough light-bending for a noticeable effect. (I don't know the equations for the lensing effect.) In this article, the planetary system is between us and a further star. Could microlensing also provide evidence of planets around the star that is furthest away in the alignment? (Has it?)

I only wish I was 40yrs younger so I would be around for the upcomming world discoveries. I'll leave it to my son to fill me in when he joins me in the other realm.

Kulick Wed, 04 Jun 2008 22:12:11 +0000 http://www.universetoday.com/?p=14662#comment-22776 julst a quick comment, The discovery of jupiter sized planets so close to their mother star was a suprise and not expected. Planetary systems were anticipated to be like our sytem. It was believed that the radiant energy from the central star pushed out matter, keeping the inner planets from getting too big. Now new theories are being proposed that would allow large planets to migrate inward to the central star. (A theory created after the fact should be recognized as a weak theory). (It is my belief that our sun exploded 5 billion years ago and stripped the inner planets of their atmospheres. This explains the evidence of the isotope of "strange xeon" and the dispursal of angular momentium of our solar system out toword Jupiter and provides the material for the astroids and explains the loss of the would be planet between jupiter and mars. ). julst a quick comment,

I'm more interested in the composition, and atmosphere. Especially a planet with a large amount of water. Be it 9 times larger than earth or not. To me, this would be a much bigger find than one the size of Mars or Earth. Large or small doesn't make a difference to me. I'm more interested in the composition, and atmosphere.

Of course it would be amazing to find one no matter how it was found. I agree with astrofiend. Of course it would be amazing to find one no matter how it was found.

" That would be disappointing in my opinion. Having the first Earth-mass exoplanet detection be a fleeting glimpse of an event with no possibility for follow-up study would be a bit of a let down in comparison to a radial velocity find which we could then train all of our equipment on over a long period of time to really nail it down and study it well. Not saying that it wouldn't still be a momentous and important achievement though... ""I'll hazard a prediction that the first extra-solar Earth-mass planet will be found by microlensing. "
