Pyrotex Posted January 25, 2006 Report Share Posted January 25, 2006 Here is a marvelous 4-frame "video" of the light echos surrounding supernova 1987-A. Like ripples in a pond. The supernova acts like a "flash" on your camera, sending out a thin "shell" of intense light in all directions. As this shell expands, it collides with clouds of gas or dust and reflects. We see the reflections as thin rings around the supernova that get larger each year. http://antwrp.gsfc.nasa.gov/apod/ap060125.html Quote Link to comment Share on other sites More sharing options...
InfiniteNow Posted January 25, 2006 Report Share Posted January 25, 2006 Yeah, I saw that myself this morning (love love love the APOD site). It's amazing that the frames shown are seperated by an entire year ( I think they show btw 2000 and 2004)... not milliseconds like the movies we watch. Ah, just a splash in the cosmic pond...
