interstellar dust (Interstellar dust), accounting for 1% of the mass of the “interstellar medium” (Interstellar medium), reflects 30% of star light in the infrared wavelength range. Dust plays an important role in the formation of stars and the evolution of galaxies. The team was led by astronomers from the Max Planck Institute for Astrophysics in Germany. I have tried to create a dust map and The first 3D dust map of our Milky Way galaxy has been published. It’s a 3D map of dust 3,000 light years away.
Astronomers revealed that Scattering and absorption of starlight by dust particles. Allowing astronomers to explore dust clouds in 3D, the 3D dust maps penetrate deeper into space with greater resolution than ever before. The processing technique allowed the team of astronomers to examine the dust distribution beyond 1 kiloparsec, while also interpolating nearby dust clouds with parsec-level precision. A parsec is the distance from the Sun. The sun reaches astronomical objects such as stars outside the solar system.
This dust map has a resolution of 1.25 kiloparsecs, and the results are consistent with previous studies. Includes available 3D dust maps. But the new map is even more satisfying. Due to the development of more comprehensive areas It has higher spatial resolution than before.
