Description:
Located in the constellation of scorpion, we have one of the most beautiful open agglomerates of our sky. Ptolemy observed this cluster as early as the second century, in 1764 Charles Messier cataloged it in his list of objects as Messier 7. In a sky with little light pollution it is possible to observe it with the naked eye, near the tail of the scorpion. It has an estimated age of 220 million years and is 800 light-years from Earth. Its apparent magnitude is 3.3. At the bottom of this image we can observe hundreds of thousands of stars. Walking through the background of this image gives us a little notion of our size in the universe. Above this dense veil of our home, the Milky Way, we can observe in its splendor the Ptolemaic Agglomerate. There are about 100 stars that make up this gem encrusted in the tail of the scorpion. Another highlight factor is the dust clouds. They cover up part of the background of the image, which gives us a sense of its density, darkening some regions of the image. In the upper left corner, we can also observe a globular cluster denominated: NGC 6453, discovered in 1837 by John Herschel
