| 説明 | I never get tired of these intimate looks into dusty nebulas facilitated by the wonder of infrared photography. This is a single-channel (monochrome) near-infrared image of an object suspected to be a binary protostar. The actual protostar is located about 1/3 of the way from the top of the image centered horizontally.A GIF animation of the protostar's light echo is available here: geckzilla.com/astro/LRLL-54361_animation.gifThe animation plays fast, but the light actually took 23 days to go that far!For further information, a press release from a few years back is available here: hubblesite.org/newscenter/archive/releases/2013/04/full/They have done their own video, but I wanted to do my own version of the animation as a looping GIF without any interpolation. Interpolation means the animation was smoothed out by adding more frames with best-guesses between the originals. I also wanted to show the rest of the image, which is nice on its own.All channels: WFC3 / IR F160WNorth is NOT up. It is 15.84° counter-clockwise from up. |
