"Astronomical sealing observatory" Document
Abu Dhabi, October 8 / WAM / The astronomical sealing observatory in the Abu Dhabi desert managed to record a series of pictures of gas and dust, and document the scenes of the birth of the stars.
After a 16 -hour photo session, the Observatory took a picture of the Teddy Bear Nebula – NGC7822, which was named by this name because of the likeness of the children’s bear doll.
Al -Sadim is located within the Group of Qivus, 2900 light years away, and its diameter is about 150 light years, which means that the light taken by the pictures was launched around the year 875 BC.
The nebula is characterized by its bright colors resulting from the ionization of gas molecules due to the UV rays issued by the surrounding stars, the most prominent of which is the star (BD+66 1673), which is one of the most heat stars near our solar system, at a surface temperature of 45 thousand degrees Celsius, which is brighter than the sun with a hundred thousand times.
The Observatory also succeeded in filming the “Trifid Nebula – M20) after 11 hours of filming; This neb is located in the bow group, 4,100 light years away, and has a diameter of about 42 light years.
The neb is divided into three lobes due to dark dust, and the stellar fountains flowing from one of the gas clouds reveal in the heart of the nebula in the form of “two centuries”, which constitute a wonderful heavenly scene as a result of the birth of a new star that pushes the surrounding gases, and the length of this fountain reaches three quarters of light years.
The observatory also managed to document an image of the “cat’s claw” in the Scorpio Group after 10 hours of filming; As the captured light was launched about 4,370 years ago.
The nebula is a nebula, an active site for the formation of stars, and appears with two distinctive colors; Red for hydrogen and blue oxygen, and this name is called to like the foot of the cat.
The photography of this nebula is difficult due to its low height from the horizon, which increases the effect of optical pollution and atmosphere on the images.
The Observatory recorded a picture of the Eagle, known as “Creation Pillars” (M16), 5700 light years within the group of lives, where the giant columns show the process of the formation of modern stars inside the nebula.
These columns were filmed using a 14 -inch diameter telescope for accurate details, as well as a 5 -inch diameter telescope for a comprehensive vision, with a comparison between the captured images and the Hubble Space Telescope, to highlight the exact capabilities of the observatory in space monitoring.
