Spiculum, Lagoon Nebula (M8, NGC6623) Facts Emission Nebula in Sagittarius

Spiculum, Lagoon Nebula (M8, NGC6623) is an emission nebula object of interest in space. It lies at a distance of about 4,100.00 light years away in the constellation of Sagittarius.

It is referred to as M(8) when it was catalogued by Charles Messier in 18th - 19th Century France. It is also referred to as NGC(6523) in the New General Catalogue. This is a list of deep space objects that was compiled by John Louis Emil Dreyer in 1888 in an update to John Herschel earlier catalogue.

The Emission Nebula's location is 18:03.8 (R.A.) and -24:23 (Dec.). Its Visual (Apparent) Brightness is 6.00 Magnitude with an apparent dimension of 90x40 . The object can be seen with the naked eye from Earth, that is, you don't need a telescope/binoculars to see it.

The Lagoon nebula (M8, NGC6523) is an Emission Nebula that was first discovered by Giovanni Battista Hodierna before 1654, and was then recovered by Guillaume Le Gentil in 1747 and independently noted as a "Nebula" by John Flamsteed about 1680 - who cataloged it as his Number 2446 ref:U.T.

Travel Time to Spiculum, Lagoon Nebula (M8, NGC6623)

The time it will take to travel to this star is dependent on how fast you are going. U.G. has done some calculations as to how long it will take going at differing speeds. A note about the calculations, when I'm talking about years, I'm talking non-leap years only (365 days).

The New Horizons space probe is the fastest probe that we've sent into space at the time of writing. Its primary mission was to visit Pluto which at the time of launch (2006), Pluto was still a planet.
