M12: Rise, Set, Nighttime Path

M12

M12 Daily Motion

M12 will reach its transit before twilight, at 18:15. By the onset of twilight at 20:34, it will be at elevation, and it will set before sunrise, at 00:08.
M12 will be visible until October, 17, 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.

M12 - Globular Cluster

M12 is a globular cluster located in the constellation Ophiuchus. It was discovered by Charles Messier in 1764. This cluster is less concentrated than other globular clusters in Messier's catalog.

M12 spans about 75 light-years across and contains tens of thousands of stars. The cluster is approximately 15,700 light-years away from Earth and has an apparent magnitude of 6.7, making it visible with binoculars or a small telescope.

M12 Image Gallery

DSS Blue

M12 photo taken with blue filter
These images are valuable for highlighting the presence of younger, hotter stars, which emit more light in the blue wavelengths.

DSS Red

M12 photo taken with red filter
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

M12 color 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 M12, 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 M12 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.
