Recently and during the twentieth conference American Astronomical SocietyFrom beautiful pictures Cosmic dust Unveiled by Herschel Telescope Recorded, a telescope that before James Webb It was the largest infrared telescope in the world.
It should be noted when looking at images of galaxies outside Milky Way We look, we generally see the light of the stars that are in them. However, the stars are not the only components of these super-cosmic structures, and if we think of a galaxy as a bowl of soup, the stars are the only vegetables in the soup.
Make no mistake, this soup in which celestial bodies float is not an empty space, and Intergalactic interface It is full of fine clouds or sometimes dense dust that usually flows in the distance between the stars.
It is worth noting that these beautiful cosmic dusts from which stars are born and will be transformed again are often lost in the bright light of their children, yet they carry a great deal of information about the structure and activities inside the galaxy.
as the same way 4 images A new version of this dust has been released, which well shows the distribution of this dust among the 4 galaxies close to the Milky Way, and from large and small clouds. MagellanicA massive spiral galaxy Andromeda With a distance equal to 2.5 million Light years as well as galaxies Triangle (Triangle) With equivalent distances 2.73 million Light years have been prepared.
New images of cosmic dust
In short, stars are formed when a dense nucleus of matter collapses inside a cold cloud of molecular gases under gravity. After death, the same star releases matter into its dense nucleus, along with other heavier elements created during its lifetime, into cosmic dust.
However, this cosmic dust is not distributed uniformly, and stellar winds, galactic winds, as well as gravitational effects are involved in the form we see in the images.
Based on the above images, Hydrogen gas Which is the most abundant element of the universe in color Red Shown are also the seemingly empty, black spots where new stars are born, which move the dusty stars around them as the wind blows, creating an empty space.
On the other hand shine Green In these images, the dust indicates that it is cold, and the blue dust indicates that the area is warmer due to stellar activity or other processes.
Finally, it should be noted that these images help scientists better understand the internal interactions of galaxies and learn more about the conversion cycle of these gases and cosmic dust.
