Publish a new detailed map of the Milky Way galaxy

A Japanese telescope has created the most detailed radio image of. For a period of 3 years, Nobeyama 45m telescope observes the galaxy Milky Way for 1100 hours to create this map.

The 45-meter Nobeyama telescope is located at the Nobeyama Observatory, near Minamimaki, Japan. The telescope has been operating since 1982, and has made many contributions to radio astronomy. This map is made using the new FOREST receiver installed on the telescope.

This image is part of a project called FUGIN.(Image source: Phys).

When we look up, a star and gas and dust will appear. But there are also black spots, which look like pores. But they are not gaps; they are molecular cold gas clouds that do not emit light, so it is difficult to see. To see what's happening in these dark clouds requires radio telescopes like Nobeyama.

This new detail will allow astronomers to study both large-scale and small-scale structures in detail. This includes providing new data on large structures such as spiral arms and even the entire Milky Way down to smaller structures such as individual molecular cloud cores.

To collect this data, the Glass observed an area of ​​130 square miles, accounting for more than 80% of the area between galactic latitudes -1 and +1 and the galactic latitudes of 10 to 50 degrees. and from 198 to 236 degrees. Basically, the map tried to observe the 1/3 and 1/4 angles of the galaxy to capture spiral arms, dust and gas cloud structures and gas molecular rings.
