The galaxy NGC 1566 is a spiral with two arms wrapped around the center of the galaxy, like a dancer snaking on a dance floor with his arms outstretched.
To photograph the Spanish Dancer, astronomers made observations of the center of the galaxy NGC 1566 with the Dark Energy Camera at the Cerro Tololo Inter-American Observatory, Chile. The spiral galaxy NGC 1566 is in the constellation Dorado about 70 million light-years from Earth.
This Spanish dancer is the brightest galaxy among about 50 other galaxies in the Dorado group. A group of galaxies is a collection of less than 50 galaxies bound by the gravitational force between galaxies.
To understand groups of galaxies, stars of different ages, and black holes, astronomers usually choose to observe the Spanish Dancer. NahThis Spanish dancing galaxy is interesting because it contains stars at all stages of evolution as well as a supermassive black hole at the heart of the galaxy. So you could say that Spanish dancers are ideal objects for studying the evolution of stars.
In the image, it appears a bright blue color at the outermost arm of the galaxy. The blue color represents very bright young stars. In addition there are dark spots inside the sleeves which are dust grooves. The galaxy arm of NGC 1566 is very rich in gas. Therefore in this area there is a large area of star formation. Close to the center of the galaxy, there is an older, cooler star with large amounts of dust in a reddish tint.
This image was taken for the needs of the dark energy survey, a study that aims to map millions of galaxies to find out about dark energy. Dark energy is one of the ingredients that make up the universe. To be more precise, this dark energy dominates the universe. This research involved 400 scientists from 26 institutions in 7 countries.
Cool Facts:
Spanish dancers are targets that have been prepared to be observed. In this galaxy astronomers witnessed a star that exploded as a supernova (SN2010el) in 2010. In addition, the James Webb Space Telescope will also observe the Spanish Dancer along with 18 other galaxies with its infrared eye!
