This Earth map fragment is intended to illustrate celestial motion across the sky, emphasizing both bearing and elevational perspectives. The map's center point corresponds to the transit, showcasing celestial objects at their highest point, while elevation gradually decreases towards the map edges. This dynamic representation offers insights into the changing positions of celestial bodies with a focus on their bearing and elevational trajectories.

M47 Observation Details

M47

M47 Daily Motion

M47 will not be observable tonight. It will reach its transit at 38° by 17:59 and set at 23:12. Throughout the night, from 04:44 to 05:22, it will be below the horizon. M47 will rise again after sunrise, at 12:42.
M47 will become visible in September, 29. After being too close to the Sun to observe, it will reappear in the night sky. Starting from September, 29, M47 can be seen again, providing a good opportunity for observation.

M47 - Open Cluster

M47 is an open cluster located in the constellation Puppis. It was discovered by Giovanni Batista Hodierna before 1654 and independently by Charles Messier in 1771. The cluster contains a rich population of young, hot stars.

M47 spans about 12 light-years across and contains around 50 stars. The cluster is approximately 1,600 light-years away from Earth and has an apparent magnitude of 4.4, making it visible to the naked eye under dark skies and easily seen with binoculars or a small telescope.

M47 Image Gallery

DSS Blue

M47 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

M47 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

M47 photo taken with Near-Infrared filter
These images can penetrate dust clouds that obscure visible light, revealing structures and objects hidden within.

DSS Composite image

M47 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 M47, 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 M47 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.
