    Scientists obtained an incredibly detailed image using ground-based telescopes nebulae where new stars are born.

    Astronomers from the Paranal Observatory, Chile, using the VISTA infrared telescope, take an incredibly detailed image of the Sh2-54 nebula, in which new stars are being born. Thanks to infrared light, scientists have been able to see the stars that hide the gas and dust from which they are born, writes Space.

    In the new image, the Sh2-54 nebula, 6,000 light-years away, appears as a bright, glowing ball containing thousands of newborn stars. This nebula lies in the constellation Serpens, which gets its name from its serpentine appearance.

    In images taken earlier by the VLT telescope from the Paranal Observatory, the stars in the nebula were mostly obscured by the huge clouds of gas and dust from which they emerge. But thanks to infrared light, astronomers were able to see through this obstacle and they were presented with a truly amazing picture.

    Now scientists were able to examine the structure of the nebula in as much detail as possible, and also protostars born in it. Before a star becomes an object that can be called a full-fledged star, it goes through the protostar stage.

    It all starts with the fact that in a nebula, such as Sh2-54, gravity forms dense patches of dust and gas, mainly consisting of hydrogen and helium. These areas increase in size over time, their mass and gravitational influence grow.

    These dense areas of space turn over time into molecular clouds that gain such a huge mass that they eventually shrink under the influence of their gravity and give birth protostar.

    Although protostars resemble ordinary stars in appearance, but they are not yet hot enough for thermonuclear fusion to begin in their nuclei. Through this process, hydrogen is converted into helium, which gives life energy to the star. Instead, the luminosity of protostars comes from matter heating up as the object continues to contract under its own gravity.

    And at this time, the protostar continues to absorb matter from the surrounding molecular cloud. When the core of this object reaches a temperature of 10 million degrees Celsius, thermonuclear fusion will begin, which will be the beginning of a real young star. But after that, the evolution of its star system begins, because the remnants of the molecular cloud still surround the young star in the form of a disk of matter, and it is in it that the formation of planets occurs.

    Scientists believe that tens of thousands are located in the Sh2-54 nebula , both protostars and young stars, so this region looks brighter than, for example, a neighboring open star cluster called NGC 6604, which is 500 light-years closer to Earth.

    Focus< /em> already wrote that the Hubble Space Telescope took a picture of the “star fireworks”, which is 50 thousand light-years away.

    As for other amazing photos from space, Focus already wrote that South Korea's first lunar orbiter took images of the Moon and the Earth.
