Until now planets around other solar systems have been detected by looking for effects from their gravitational pull on the stars that they orbit.

Now we have the first images , announced on the same day, one from Hubble, and one from a large earth based telescope.  

Fomalhaut

HR 8799

These are both young (~300million year old) stars, so the planets are still hot.

Pictures of earth-like planets will have to wait for the launch of the Terrestrial Planet Finder Mission.

Pogge:” This is the volume of a sphere with a 62 kilometer (about 39 miles) radius, which is considerably smaller than the 2,000 mile radius of the Earth.”
Wikipedia:” For Earth, the mean radius is 6,371.009 km(≈3,958.761 mi; ≈3,440.069 nmi).”
Wisp to Lester (on Pogge): Do you admit he was wrong about the basics?
Lester: No

Very exciting!  This is going to be something to keep an eye on as the technology and technique advances.  Eventually I think we'll find an earth-size planet with a telltale spectra of life on it.  An atmosphere with free ozygen in it would be a sure sign of life, for example.
