We have some great chances to see a new comet this month which won't be back for another 6800 years.
The comet is named NEOWISE after the NASA mission that discovered it: the Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE). It will be a little easier to see in the northwest sky every night through July 23. To the naked eye, NEOWISE will look like a fuzzy star with a bit of a tail, NASA says. So try to use at least binoculars or a small telescope.
“From its infrared signature, we can tell that it is about 5 kilometers [3 miles] across, and by combining the infrared data with visible-light images, we can tell that the comet’s nucleus is covered with sooty, dark particles left over from its formation near the birth of our solar system 4.6 billion years ago,” said Joseph Masiero, NEOWISE deputy principal investigator at NASA’s Jet Propulsion Laboratory in Southern California.
To find NEOWISE, look just below the Big Dipper in the northwest sky. Remember, the time to look is just after sunset. It’s about that simple, but the map below is a good guide. Happy comet hunting!
