Interstellar dust, which represents 1% of the mass of the interstellar medium, reflects 30% of starlight in the infrared wavelength range. Dust plays an important role in star formation and galaxy evolution. The team was led by astronomers from the Max Planck Institute for Astrophysics in Germany. I attempted to create a dust map and the first 3D dust map of our Milky Way Galaxy was published. It's a 3D map of dust 3,000 light-years away.
Astronomers revealed that scattering and absorption of starlight by dust particles. By allowing astronomers to explore dust clouds in 3D, 3D dust maps penetrate deep into space with greater precision than ever before. The processing technique allowed the team of astronomers to examine dust distribution beyond 1 kiloparsec, interpolating nearby dust clouds to a resolution down to the parsec level. A parsec is the distance from the Sun, and 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 much more satisfying. Due to the development of more extensive fields it has a higher spatial resolution than before.
