Andromeda is 2.5 million light years from the Milky Way, a spiral galaxy similar to ours which allowed scientists to better understand our galactic house. A new composite image reveals our closest galactic neighbor in five different light lengths, combined together to create an incredibly detailed view of Andromeda.
Telescopes capture images in different wavelengths by observing a specific part of the electromagnetic spectrum, radio waves at low frequency with extremely high frequency gamma rays. Using different wavelengths, astronomers can see many more cosmos, whether dust and shiny stars or collision galaxies.
For the latest image of Andromeda, also known as M31, astronomers presented X -ray data from the Chandra Observatory of NASA, revealing high energy radiation around the supermassive black hole in the center of the galaxy.
The X-ray data, captured by the XMM-Newton of the European Space Agency, is presented in red, green and blue. UThe NASA Retirement LTTRAVILET data is in blue; The infrared data of the retired Spitzer Spitzer of NASA, the satellite of infrared astronomy, Cobe, Planck and Herschel are in red, orange and purple; and the radio data of Westerbork synthesis Nasa. AStrophotographers Jakob Sahner and Tarun Kottary provided optical data using ground telescopes.
Andromeda is a classic spiral, with graceful arms that revolve around a central bulge. It covers 220,000 light years, twice the size of the Milky Way. The two galaxies are on a collision course unfortunate with each other and are expected to merge in around 4.5 billion years. Or maybe notAs research suggested earlier this month.
Astronomers have also converted multiple wavelength data into sound, creating a beautiful melody from Andromeda dust and star clusters. To create the new Andromeda song, scientists separated the layers captured by each telescope and stack them on each other horizontally, starting with X -rays at the top, then moving with Ultraviolet, Optics, Infrared and Radio at the bottom.

Each type of light is mapped to a different range of notes, low -energy radio waves throughout the high energy of X -rays. The brightness of each source controls the volume of the galactic song, and the vertical location dictates the height.
The latest composite image of Andromeda was released in honor of the legendary astronomer Vera Rubin, who discovered evidence of dark matter by measuring the speed of stars in the spiral galaxy. In the 1960s, Rubin carefully observed Andromeda and determined that the invisible matter affected the way in which the spiral arms of the galaxy turned. Earlier this week, the Vera C. Rubin observatory, named after the pioneer astronomer, published his very first images of the cosmos.
