Images of strange solar system visitor peel away some of the mystery
Madison WI (SPX) Nov 17, 2017
A strange visitor, either asteroid or comet, zipping through our solar system at a high rate of speed is giving astronomers a once-in-a-generation opportunity to examine up close an object from somewhere else in our galaxy. "It's a really rare object," explains Ralf Kotulla, a University of Wisconsin-Madison astronomer who, with colleagues from UCLA and the National Optical Astronomy Observatory (NOAO), used the 3.5 meter WIYN Telescope on Kitt Peak, Arizona, to take some of the first pictures of ... read more
