Interesting crater on Thebe

[vogon13]

Jupiters enormous gravity has an enormous focusing effect on debris that passes near the Jupiter system.<br /><br />Thebe is one of the closest moons to Jupiter we know of.<br /><br />In addition to the lightning, IIRC, Voyager photographed meteors on Jupiters dark side.<br /><br /><br /><br /> <div class="Discussion_UserSignature"> <p><font color="#ff0000"><strong>TPTB went to Dallas and all I got was Plucked !!</strong></font></p><p><font color="#339966"><strong>So many people, so few recipes !!</strong></font></p><p><font color="#0000ff"><strong>Let's clean up this stinkhole !!</strong></font> </p> </div>

I see I still don't have the knack for enlarging yet. The pic, while small, does seem to sharpen up some of the surface features. {found the enhaced version on another site}<br /><br /><br /><br /> <div class="Discussion_UserSignature"> <p><font color="#ff0000"><strong>TPTB went to Dallas and all I got was Plucked !!</strong></font></p><p><font color="#339966"><strong>So many people, so few recipes !!</strong></font></p><p><font color="#0000ff"><strong>Let's clean up this stinkhole !!</strong></font> </p> </div>

Enlarging a small image only enhances the low resolution that makes the small image small to begin with which has nothing to do with your image enhancement skills. <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.

The thinking goes that while space seems very empty, given enough time (and the majority of these objects are billions of years old), impacts are inevitable. <p><hr /></p></p></blockquote>The craters on Thebe, Mimas, and Tethys, as well as Callisto, Miranda, Proteus, and other gas-giant moons, are too uniform to be explained by chance encounters. These are organized.<br /><br />Objects formed in a moon's L4 and L5 points will zero in on the moon and hit it every time. So you see a bunch of high-mass, low velocity craters.

I didn't enhance the image, it was done at another site by someone who stacks images and some other techniquesI don't understand. I have so few computer skills, I can't even post a pic the size it was on his site. It did look better. The one 'spot' now appears to be a largish chunk of debris lying on the surface.<br /><br />I just wamted to post two pictures at the same size to highlight what the processing did. The little runty postage stamp image makes me sad.<br /><br /><br /><img src="/images/icons/frown.gif" /><br /><br /><br /><br /><br /><br /><br /> <div class="Discussion_UserSignature"> <p><font color="#ff0000"><strong>TPTB went to Dallas and all I got was Plucked !!</strong></font></p><p><font color="#339966"><strong>So many people, so few recipes !!</strong></font></p><p><font color="#0000ff"><strong>Let's clean up this stinkhole !!</strong></font> </p> </div>

It's over at UMSF, I'll try and get the coordinants when I am done here. Thanx for your interest.<br /><br /><br /><br /> <div class="Discussion_UserSignature"> <p><font color="#ff0000"><strong>TPTB went to Dallas and all I got was Plucked !!</strong></font></p><p><font color="#339966"><strong>So many people, so few recipes !!</strong></font></p><p><font color="#0000ff"><strong>Let's clean up this stinkhole !!</strong></font> </p> </div>

This is a simple 4x enlargement of the enhanced image you posted. <div class="Discussion_UserSignature"> <font size="3" color="#ff9900"><p><font size="1" color="#993300"><strong><em>------------------------------------------------------------------- </em></strong></font></p><p><font size="1" color="#993300"><strong><em>"I hold it that a little rebellion now and then is a good thing, and as necessary in the political world as storms in the physical.

I think Thebe is like a rubble pile held together by grivity, much like the main belt asteroid 253 Mathilde (as seen by the NEAR on way to asteroid 433 Eros). Such objects can be hit hard without shattering, as the loosly held material can be 'pushed in'. <br /><br />Thebe's bigger inner sibling Amalthea has also been seen to have a low density, thus increasing my suspicions that Thebe too is of low density. Interesting feature though. <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world.
