2.5 million light-year away from Andromeda Milky Way, which is a spiral galaxy like our own that has allowed scientists to better understand our village. A new overall image reveals our nearest galactic neighbor in five different wavelengths of light, combined together to create a surprisingly detailed view of Andromeda.
The telescope captures images in various wavelengths, which, from low -frequency radio waves to extremely high frequency gamma rays, looking at a specific part of the electromagnetic spectrum. By using different wavelengths, astronomers are able to see the universe more, whether dust and stars shine or colliding with galaxies.
For the latest image of Andromeda, also known as M31, astronomers depicted X-ray data from NASA’s lunar observatories, which reveals high-energy radiation around the supermasive black hole at the center of the galaxy.
X-ray data captured by the XMM-Nuton of the European Space Agency is shown in red, green and blue. YouLtraviolet data from NASA’s retired galax is in blue; NASA’s retired Spitzer Space Telescope, Infrared Astronomy Satellite, Cob, Planck and Hersel infrared data in red, orange and purple; And according to the radio data radio telescope in red-orange, from Westerborec synthesis NASAAStrophfotographer Jacob Sahner and Tarun Kotri provided some optical data using ground-based telescopes.
Andromeda is a classic spiral, with beautiful weapons that revolve around a central bulge. It is spread over 220,000 light-year, double the size of the Milky Way. The two galaxies are on a course of an unfortunate confrontation with each other and are expected to merge in about 4.5 billion years. Or Maybe notAs the research published earlier this month suggested.
Astronomers also converted multi-wavelength data into sound, making Andromeda a beautiful tune from the dust lane and star cluster. To create a new song from Andromeda, scientists separated the layers captured by each telescope and stack them horizontally over each other, initially started with X-rays and then proceeded through ultraviolet, optical, infrared and radio.

Each type of light is mapped into a separate range of notes, through high energy of X-rays from low-energy radio waves all the way. The brightness of each source controls the amount of Ganges song, and the vertical location directs the pitch.
Andromeda’s latest overall image was released in honor of the mythological astronomer Vera Rubin, who found evidence for the dark matter by measuring the velocity of stars in the spiral galaxy. In the 1960s, Rubin carefully looked at Andromeda and determined how the unseen matter was affecting how the galaxy spirals were rotated. Earlier this week, Vera c. Rubin Observatory, named after the leading astronomer, Released its first images of the universe,
