<p>Of course, they&#8217;re about as detailed as pictures of the stars at a science-fiction convention panel taken from the back of the room, or the band on stage from the upper-top-fifth-tier seating (see! that dot there is so-and-so!), but still&#8230;it&#8217;s a start.</p>
<p>There&#8217;s one photo from Hubble of the planetary debris disc around <a href="http://en.wikipedia.org/wiki/Fomalhaut">Fomalhaut</a>, with a little dot that apparently has been tracked in other images, consistent with being in orbit around the star.  It&#8217;s estimated at being about the size of Jupiter and about four times as far out from its star as Neptune is from the sun.</p>
<p>Meanwhile: consider that <strong>we can see something the size of Jupiter even though it&#8217;s 25 light years away!</strong></p>
<p>Then there&#8217;s one from the Gemini North telescope that has actually caught <strong>two</strong> planets in orbit around a star called HR 8799 &#8212; a photo of a <strong>planetary system</strong>!</p>
<p><b>Update:</b> Hubblesite <a href="http://hubblesite.org/newscenter/archive/releases/2008/39/">has more on Fomalhaut</a> including this image showing Fomalhaut B&#8217;s location in 2004 and 2006:</p>
