Astronomers make detailed record of the Medusa Nebula




Using the Very Large Telescope of ESO in Chile, astronomers have captured the most detailed picture to date of the Medusa Nebula. The spray is formed by a dead star in the middle of the gas cloud.

ESO VTL Medusa Nebula This requires the organization on its site. The new images of the Medusa Nebula are based on data from the Fors -camera on the VLT. This camera is part of the Antu telescope of the VLT and is also called the “Swiss Army Knife” of the telescope named for its properties to capture astronomical objects in many different ways. For example, the Fors a camera for visible light, it can be used for multi-object spectroscopy and the instrument is able to measure the polarization of light. The camera includes two 4K CCD with pixel size of 15μm.

The Medusa Nebula, also known as Abell 21 and Sharpless 274, located 1,500 light-years from Earth. The diameter of the nebula is an estimated 4 light-years but despite this size, the quality of the wax images until now a fraction of those of the new images. The hoses in the nebula are the serpentine glowing gases in the nebula. The red glow comes from oxygen, which results in soft green. Because the gas discharge of the star extinguished intermittently come out, rise to the structures.

The nebula is in the constellation Gemini and was discovered in 1955. The nebula is named after the Gorgon Medusa from Greek mythology. The mythical Medusa would have aroused the wrath of Athena, and Athena Medusa’s hair turned into a nest of writhing snakes and anyone who looked at Medusa’s eyes would turn to stone.
