European Observatory at night to see the amazing sights

The European Southern Observatory (ESO) has released the most detailed”ominous” image of the Sirius 3 Dark Nebula to date.Sirius 3 The dark nebula is one of the densest star-forming regions closest to the sun. Sirius 3 is about 600 light-years away from Earth, in the direction of the constellation Scorpio, and is believed to have a large number of young stars and protostars.

Nebula is an amazing collection of cosmic dust and gas, Under the reflected light of hot, bright young stars, they glow in their diffuse form. Most of the stars in our galaxy are formed in smaller star”nursery”, like Sirius 3, which makes astronomers try to understand how stars form and develop.

Sirius 3 is a dark nebula, also known as the light-absorbing nebula. The dust particles that form this special cosmic cloud are so cold and dense that they effectively block and scatter most of the light emitted by the stars embedded in them, giving them a dark, ominous appearance.

The new ESO image is actually made by ESO’s Very Large Telescope and the aperture 2.2 A collage of many smaller images taken by Mi’s MPG/ESO telescope, both in Chile.

The interference in the molecular dust causes it to gather together, forming a denser junction than the surrounding material. Over time, more and more materials are attracted until the dense nebula collapses under its own gravity and starts to heat up, resulting in the creation of one or more protostars.

This is also 40 During the birth of our sun billions of years ago, two dazzling stars can be seen in the center of the image above. These medium-mass, bright blue stellar bodies are called Herbig Ae/Be (HAeBe) stars, which were once hidden in the nebula’s suffocating material. However, they will become hotter and bigger afterwards. This transition caused strong solar wind and star radiation, effectively clearing the surrounding nebula material, so that they can appear and shine into the universe. Despite their ability to destroy nebulae, HAeBe is not yet mature. The light they emit is the result of the conversion of gravitational energy into heat due to core contraction.
