Ball lightning is a possible source of legends that describe luminous balls, such as the mythological Anchimayen from Argentinean and Chilean Mapuche culture.. According to a statistical investigation carried out in 1960, of 1,962 Oak Ridge National Laboratory monthly role personnel, and of all 15,923 Union Carbide Nuclear Company personnel in Oak Ridge, found 5.6% and 3.1% respectively ...
Global map of lightning frequency--strikes/km 2 /yr. The high lightning areas are on land located in the tropics. Areas with almost no lightning are the Arctic and Antarctic, closely followed by the oceans which have only 0.1 to 1 strikes/km 2 /yr. The map on the right shows that lightning is not distributed evenly around the planet. [5]
NGC 6397 (also known as Caldwell 86) is a globular cluster in the constellation Ara that was discovered by French astronomer Nicolas-Louis de Lacaille in 1752. [9] It is located about 7,800 light-years from Earth, [3] making it one of the two nearest globular clusters to Earth (the other one being Messier 4).
See also: Globular cluster, List of globular clusters NGC 6558 is a globular cluster , located about 24,000 [ 4 ] [ a ] light years away in the constellation Sagittarius . Its apparent magnitude is about 11 and its apparent diameter is about 10 arcminutes. [ 2 ]
NGC 6760 is a globular cluster [2] in the constellation Aquila. It may have contributed to the formation of the open cluster Ruprecht 127 during NGC 6760's passage through the galactic disk 71 million years ago. [5] At least two millisecond pulsars have been found in NGC 6760. [6]
As lightning is influenced by climate change, there is a corresponding change to the lightning’s influence on climate. These changes can lead to further climate change, thus creating a climate change feedback. [173] Lightning leads to the production of tropospheric ozone and destruction of methane, both greenhouse gases and air pollutants ...
NGC 6441, sometimes also known as the Silver Nugget Cluster, [9] is a globular cluster in the southern constellation of Scorpius.It was discovered by the Scottish astronomer James Dunlop on May 13, 1826, who described it as "a small, well-defined rather bright nebula, about 20″ in diameter".
NGC 6624 is a globular cluster in the constellation Sagittarius. It was discovered on 24 June 1784 by the astronomer William Herschel. It is given an apparent magnitude of 7.6 to 8.5. [4] Six pulsars are known in NGC 6624. The first of these to be discovered was PSR J1823-3021A.
