While looking at an Unknown object they found a comet that is so close you can now see it with the naked eye in the Northern Hemisphere.
NEOWISE did, however, manage to discover another object that they understand more about. Late last year, they also found C/2016 U1, a comet that is cruising by Earth right now.
It will be viewable from the Northern Hemisphere during the first week of 2017 in the southeastern sky during the hours before sunrise. You’ll even be able to catch a glimpse of it with a good pair of binoculars, if the cloud coverage and unpredictable brightness of the comet is favorable.
