25 Dark Sky Parks In The U.S. To See The Comets, Meteors And Aurora
Comet Lemmon and Comet SWAN, both green from released gases, are visible this week with closest approaches on Monday and Tuesday, offering a rare dual comet sighting.
- Skywatchers in the Northern Hemisphere can currently spot two bright green comets, Comet Lemmon and Comet SWAN , streaming across the sky.
- Originating from the solar system's outer reaches, Comet Lemmon and Comet SWAN are frozen leftovers from the solar system’s formation billions of years ago.
- Heating toward the sun causes gas release that makes them green, with Comet SWAN spotted by an amateur using NASA and the European Space Agency photos, while Comet Lemmon was found by telescopes searching for near-Earth asteroids.
- After sunset, look low to the horizon for Comet Lemmon in the north and Comet SWAN in the southwest; both appear as gray, fuzzy patches visible with binoculars through the end of the month.
- On Monday, Comet SWAN will fly by Earth but likely dim as it moves away from the sun, while Comet Lemmon approaches closest on Tuesday; earlier this year, a green comet broke up.
