Lagoon Nebula (M8) Observation Details

M8 Daily Motion

M8 will reach transit at 14:30. By the time twilight starts at 18:13 it will be at an elevation of 7° degrees and will set at 19:00, before twilight ends.
M8 will be visible until January, 1, when it will move too close to the Sun. During this time, its proximity to the Sun will cause it to disappear from the night sky, making it unobservable for a while.

M8 - Lagoon Nebula

The Lagoon Nebula (M8) is a giant interstellar cloud in the constellation Sagittarius. It was discovered by Guillaume Le Gentil in 1747 and included in Messier's catalog in 1764. The nebula is a region of active star formation.

M8 spans about 110 light-years across and is illuminated by the hot young stars it contains. The nebula is approximately 4,100 light-years away from Earth and has an apparent magnitude of 6.0, making it visible to the naked eye under dark skies and easily seen with binoculars or a small telescope.

M8 Image Gallery

DSS Blue

These images are valuable for highlighting the presence of younger, hotter stars, which emit more light in the blue wavelengths.

DSS Red

These images are excellent for detecting older, cooler stars, as well as emission nebulae, which glow primarily in the red due to hydrogen alpha emissions.

DSS Near-Infrared

These images can penetrate dust clouds that obscure visible light, revealing structures and objects hidden within.

DSS Composite image

DSS Color images are composite images created by combining the blue, red, and often near-infrared images to produce a full-color representation.

The photos are taken from the Digitized Sky Survey 2 (DSS2), which was produced at the Space Telescope Science Institute (STScI) under NASA contract, using data from the UK Science and Technology Facilities Council (STFC), the European Southern Observatory (ESO), and the National Geographic Society-Palomar Observatory Sky Survey (POSS II).

Special thanks to the National Optical Astronomy Observatory (NOAO), the Royal Observatory, Edinburgh, and the California Institute of Technology for their significant contributions.

The graph illustrates the annual visibility pattern of a M8, providing a comprehensive overview of its daily appearances and transit times throughout the year.
The graph is structured with the vertical axis showing the hours of the day, ranging from 12 AM to 12 AM the next day, while the horizontal axis spans each day of the year.
The reddish shaded area indicates the periods when the M8 is above the horizon, visible to observers. The white line marks the times when the celestial object reaches its highest point in the sky each day, known as the transit.
