http://nightskylive.net has live feeds from a number of small fish-eye lens all-sky cameras installed at major observatories around the world. I couldn't access their site checking it just now, but I think it usually works. They aren't necessarily the prettiest pictures you'd see (black and white, with fish-eye distortion) but you can usually pick out some of the prominent constellations, the milky way, the moon if it's up (though it saturates the camera). You can sometimes also catch neat things such as satellites/iridium flashes, meteors or the zodiacal lights. I think most people use them though as a way to check the weather conditions outside without leaving the telescope control room <img src="/images/icons/smile.gif" />. <br /><br />Probably the best live astronomical images you can get are of the Sun. These are taken with the SOHO space telescope -
http://sohowww.nascom.nasa.gov/data/realtime-images.html<br />The real-time movies linked at the bottom show the sun over the last 48 hours. The EIT images are images taken at different extreme ultaviolet wavelengths (you're looking at the corona here - these are all false-color in that human eyes can't see extreme ultraviolet light) you can see things like flares and prominences in these images, the MDI Continuum image is basically what the Sun looks like in light that we can see - you can watch spots moving across the disk of the sun in these movies, the MDI Magnetogram shows the magnetic field on the sun, the two LASCO movies show the corona/solar wind away from the Sun (the sun itself is blocked out with the big circle in these images) you can see lots of neat things in the LASCO movies like mass ejections, and you can also watch the stars appear to move in the background (due to the telescope orbiting the sun, actually at the same period that the Earth orbits it).<br /><br />T <div class="Discussion_UserSignature"> </div>
