Most Detailed Thousand-Color Image of Galaxy Unveiled
In the online researches in the Journal of Astronomy and Astrophysics on June 18, astronomers have achieved a groundbreaking milestone by capturing the most complex appearance of a galaxy to date. The photographs of the sculptor galaxy, also known as the NGC 253, which is about 11 million light years, exhibit the galactic system in thousands of colors, and a sharp contrast with its normal Galaxy paintings containing only one hand. Astronomers used the European Southern Observatory (ESO) instrument in Chile to observe the galaxy for more than 50 hours, and brought together more than 100 exposure to 65,000 light years in the galaxy, 90,000 light years. By mapping the galaxy on thousands of wavelengths, the team was able to analyze the age, composition and movement of the stars, gas and dust in sculptor galaxy.
With extraordinary sensitivity.
According to Universidad de Chile team leader Enrico Congiu, “Sculptor Galaxy is at a sweet point. We can solve the internal structure and examine the building blocks with incredible details, but we can still see it as a whole system.” The image cannot only zoom the working zones created by the stars on the same scale by an individual star, but also zoom to examine the entire galaxy. In the first examination, scientists were able to identify about 500 new planetary nebulars, an incredibly rare detection, except for our own straw. Beyond our Galactic neighborhood, we are usually dealing with less than 100 detection per galaxy about the importance of this discovery. These planetary nebulahs serve as vital markers to measure the distance that is very important for more work on the structure and evolution of the galaxy. This new image offers scientists a comprehensive map of the life cycle of sculptor galaxy, as well as exhibiting the beauty of galaxies. Other projects that use the map will investigate how the gas flows and changes while creating stars in this galaxy.
Before that, the most detailed observation of the sculptor galaxy was recorded in 1998 by Hubble Space Telescope. The galaxy has been observed many times since then and
Binoculars in ideal conditions.
