Astronomers at Max Planck Institute for astronomy has just created a three -dimensional map of our galaxy dust.
The map uses 130 million spectrum spectrums from the European Gaia mission to reveal the properties of dust, which causes the universe between our world and everything in the Milky Way. The 3D map states that most clouds are the waters of the universe, as well as the regional chart. The “extinction” of light is less affected than specific. The research of the team is Published Today in science
Dust distorts the perspective of the stars and other bodies, causing them to appear to live life and fade more than they are. The latter effect is called extinction or absorption and scattering of the background light by medium objects – in this case, grains dust.
From the 220 million specifications issued by the GAIA mission in June 2022, the research team chose 130 million stars they specified will be used for searching for their dust.
After that, the researchers trained the nervous network – the learning system of the machine that pulled the conclusion by mimic the process of the nerve cells in the brain – to create the spectrum according to the qualified qualifications of the dust.
The creation of the above image shows how the dust arcs caused by dust around our sun for up to 8,000 light years in all directions. The red region in the graphics that the extinction of the light depends on the length of the increased wave, which does not depend on the length of the wave in the blue area.
The gray shape shows the area that has a density of dust rising in the map. And if the above graphics make you not see the greatness in this part of the universe, just look at the Web space telescope Shock Of Carina Nebula (at the bottom of the top image)
According to the Max Planck Institute releaseThe 3D map also revealed that the extinction curve for a dense area of dust. (Consistent with only 20 pounds or 10 kilograms or dust in the world with radius of the world) more steep than expected Researchers are wondering if a steep curve may be caused by hydrocarbons in a fertile form in the universe – the position they hope to understand by observing more.
Gaia gather Observing more than three trillion The Chang Chang between July 24, 2014 to January 15, 2025. After that, Gaia's in and out of the Space, the information of GAIA helps scientists create a newly created viewpoint of our galaxies, as it seems that external observers in January. But not all maps: Telescopes also have a great record with a black hole, helping researchers stating The heaviest black hole In April 2024 and found The well known black hole To the world in 2022
