Thanks For The Heat, SDC

Thanks For The Heat, SDC<br /><br />The Spitzer Gallery: The Heat Is On ... from the link on the homepage is really nice. I copied each caption and picture to it's own directory. Keeping up on Astronomy is getting tough. Remember black and white? Things were easy then; I only had to remember one way for something to look. Now, with IR, X-RAY, UV and visible wavelengths, it is getting hard for me to keep track of what is what. Is it the Eskimo in visible or the Ring in IR? That's not a real good example off the top of my head, but does anyone else get the feeling that sometimes a thing will look, in one wavelength, like something else in another?<br /><br />This link will probably still work after the gallery is off the front page.<br /><br />http://www.space.com/php/multimedia/imagegallery/igviewer.php?imgid=3725&gid=272&index=0<br /><br />Anyway, thanks SDC for getting all those great pictures in one place for me. <br /> <div class="Discussion_UserSignature"> </div>

That is very cool. <img src="/images/icons/wink.gif" /><br /><br />My favorite example of how things vary in different wavelengths is the Crab Nebula. During the Saturn occultation, Hubble and Chandra teamed up to take pictures in multiple wavelengths; Spitzer was, alas, not yet available. But it's really remarkable, and the motion pictures they took are especially astounding. In X-ray, most of what you see is the pulsar, its accretion disk, and two jets over its poles. But that's not how it looks in visible frequencies.<br /><br />Check this out. It's a composite of the Crab in three freqeuncies. Red is radio, green is visible light, and blue is X-ray. I got it from Astronomy Pic of the Day. <div class="Discussion_UserSignature"> <p> </p><p><font color="#666699"><em>"People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint it's more like a big ball of wibbly wobbly . . . timey wimey . . . stuff."</em>  -- The Tenth Doctor, "Blink"</font></p> </div>

You are right about that, the X-ray part of the Crab still seems pretty unique to me. <div class="Discussion_UserSignature"> </div>
