The “pillars of creation”, a vast region of new stars in the Eagle Nebula, some 6,000 light-years away, have become a true attraction for astronomers studying the Milky Way since their discovery through the Telescope. Hubble Orbital. nineteen ninety five
Currently, as can be seen in a new image obtained by Hubble, these columns of cosmic dust and gas are being dispersed by the stellar wind of illuminated young massive stars in this “stellar motherhood,” reports Sunday Live Science.
The new Hubble image is in the infrared spectrum, invisible to human eyes. In this image of the “Pillars of Creation” many new illuminated young stars are visible in the dust clouds that form this galactic structure.
Spanning a distance of 5 light years (nearly 3.5 times the diameter of the Solar System), the “Pillars of Creation” are natural incubators for embryonic stars, thanks to numerous pockets of hydrogen gas, according to NASA. . As increasing amounts of cosmic gas and dust accumulate in areas or nuclei of greater gravity, these areas heat up due to the friction between the dust and the gas particles and represent embryonic stars or protostars. If such a prototype continues to attract gas and cosmic dust around it, its mass increases, and the temperature and pressure reach the levels at which the reaction of nuclear fusion of hydrogen into helium begins, a new star is born.
As you can see from the image, the most active region where new stars light up in this area of the Eagle Nebula is at the top of the largest of the “Pillars of Creation”, which glows with blue radiation .
According to NASA astronomer Paul Scowen, who coordinated Hubble’s initial exploration of the Eagle Nebula in 1995, as the stars at the top of the “Pillars of Creation” get larger, their radiation becomes stronger and begins to dissipate. gas clouds and cosmic dust around.
“These gas pillars are in the process of ionization, a process by which the electrons separate from their atomic orbits and are strongly heated by radiation from the massive new stars around them. Strong stellar winds and the dam of ionized particles emitted by these stars simply destroy the top of these pillars, “Scowen explained in a scientific statement released in 2015 by NASA.
This is probably why that image is really special, Live Science notes. The “Pillars of Creation” are changing and we will never see them exactly as they were when this picture was taken.
