Uranus, when discovered in 1781, was the first planet discovered using technology (a telescope) rather than being spotted by the naked eye. Theoretically, in a typical dark sky, the dark adapted human eye would see the about 5,600 stars brighter than +6 m while in perfect dark sky conditions about 45,000 stars brighter than +8 m might be visible.
According to photos and experiences from viewers, the northern lights were visible to the naked eye May 10-11 in the Asheville area. Though previous reporting from the Citizen Times stated that ...
The limiting magnitude for naked eye visibility refers to the faintest stars that can be seen with the unaided eye near the zenith on clear moonless nights. The quantity is most often used as an overall indicator of sky brightness, in that light polluted and humid areas generally have brighter limiting magnitudes than remote desert or high altitude areas.
The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated in the Milky Way, being south of Orion's Belt in the constellation of Orion, [b] and is known as the middle "star" in the "sword" of Orion.

28.2 (in 2003) [14] Halley's Comet, Comet Halley, or sometimes simply Halley, officially designated 1P/Halley, is the only known short-period comet that is consistently visible to the naked eye from Earth, [15] appearing every 75–79 years. [1] It last appeared in the inner parts of the Solar System in 1986 and will next appear in mid-2061.
