Comet McNaught as the Great Comet of 2007. A great comet is a comet that becomes exceptionally bright. There is no official definition; often the term is attached to comets such as Halley's Comet, which during certain appearances are bright enough to be noticed by casual observers who are not looking for them, and become well known outside the astronomical community.
It was the brightest comet in over 40 years, and was easily visible to the naked eye for observers in the Southern Hemisphere in January and February 2007. With an estimated peak magnitude of −5.5, the comet was the second-brightest since 1935. [6] Around perihelion on 12 January, it was visible worldwide in broad daylight. Its tail measured ...
Comet Hale–Bopp (formally designated C/1995 O1) is a long-period comet that was one of the most widely observed of the 20th century and one of the brightest seen for many decades. [10] [11] [12] Alan Hale and Thomas Bopp discovered Comet Hale–Bopp separately on July 23, 1995, before it became visible to the naked eye.
The unusually bright quasar is located 13 billion light-years away and experts say the discovery could unlock clues about our universe’s early beginnings.
The comet, known as C/2024 G3 or ATLAS, could be the brightest of 2025, but it’s too early to tell, said Bill Cooke, lead of the National Aeronautics and Space Administration’s Meteoroid ...
Neowise, which is named after the space telescope used to discover it, is also the brightest comet to appear in 23 years (the last was Comet Hale-Bopp in 1997).
The comet became bright enough to photograph in broad daylight, [16] [17] and was reported to be visible with the naked eye. [18] This made the comet the fifth comet in the last 100 years to have been observed in the daylight with the naked eye, joining Skjellerup-Maristany in 1927, Ikeya-Seki in 1965, West in 1976, and McNaught in 2007.

A comet that orbits the Sun every 160,000 years will appear in the night sky this week, offering a rare chance. The Comet C/2024 G3 (ATLAS) is expected to be the brightest comet in nearly 20 years ...
