[SAPOD]Today’s “Space Image”. We introduce characteristic images introduced by sorae in the past, attractive images released by space agencies of various countries, and images submitted by space astronomy fans and experts. (There is a link to the original article at the end of the article)

- *** – A collaboration between three space telescopes. “Phantom galaxy” “M74” captured with multiple wavelengths
This was introduced by sorae in an article on June 3, 2023.Spiral galaxy “M74”“is.
M74 is a spiral galaxy located approximately 32 million light-years away in the direction of the constellation Pisces, and is known as a “grand design spiral galaxy” because it has distinct spiral arms. ) are classified.
This image was not taken with a single telescope. The images were created using data acquired by the Hubble Space Telescope, the Chandra X-ray Observatory, and the James Webb Space Telescope.

In this way, observing the same celestial body not only with visible light but also with electromagnetic waves of various wavelengths such as infrared, ultraviolet, radio waves, and X-rays is called “multi-wavelength observation.” Multi-wavelength observation reveals properties and structures that are not clear when observing only at a specific wavelength.
