✨🇲️🇦️🇬️🇮️🇨️🇦️🇱️ 🇺️🇳️🇮️🇻️🇪️🇷️🇸️🇪️ - The open cluster Collinder 261

Using the Very Large Telescope, an international team of astronomers has shown how to use the chemical composition of stars in the clusters to learn more about the formation of our Milky Way. This discovery is a fundamental test for the development of a new chemical marking technique that discovers the birth and growth of our galactic cradle. The formation and evolution of galaxies, and in particular of the Milky Way, the so-called Insular Universe, in which we live, is one of the greatest riddles of astrophysics, in fact there is still a detailed physical scenario and its comprehension requires the effort set of observations, theories and complex numerical simulations. ESO astronomer Gayandhi De Silva and his colleagues used the Ultraviolet Spectrograph and Visual Echelle (UVES) in the VLT to find new ways to approach this fundamental enigma. "We have analyzed in great detail the chemical composition of the stars in three stellar groups and we have shown that each group has a high level of homogeneity and a very distinctive chemical signature," says De Silva, who began this research while working on Mount Stromlo. Observatory, in Australia. "This paves the way to chemically label stars in our galaxy in common star formation sites and thus unravel the history of the Milky Way," he adds. "Galactic star clusters are witness to the galactic disk's formation history," says Kenneth Freeman, also of Mount Stromlo and another member of the team. "The analysis of its composition is like studying ancient fossils, we are chasing pieces of galactic DNA!" The open star clusters are between the.....

✨🇲️🇦️🇬️🇮️🇨️🇦️🇱️ 🇺️🇳️🇮️🇻️🇪️🇷️🇸️🇪️ - Nebulae in Orion by Terry Hancock

At Grand Mesa Observatory we have collected an image processed in an unusual way by the extraordinary astronomer Terry Hancock. With a total of 12 hours of exposures, the composition was processed by assigning to the Hubble palette the red color to sulfur SII, the green to hydrogen H-Alpha and the blue to oxygen OIII. The fans of space science have no choice but to marvel at the view of the complex of nebulae of Orion that the elaborate image offers us. Up in the center is the Great Orion Nebula M42, which shines brightly in the colors assigned by the astrophotographer, the technological advances in photographic processing allow to see with better details the filaments of which both the internal and external part of the great nebula. The Orion Nebula, cataloged as Messier 42 and NGC 1976, is a diffuse nebula located south of the Orion belt. It is one of the brightest nebulae that exist, and can be observed with the naked eye over the night sky. It is located 1,270 light years from Earth, and has an approximate diameter of 24 light years. The Orion Nebula is one of the most photographed, examined, and investigated astronomical objects. From it has obtained decisive information about the formation of stars and planets from clouds of dust and gas in collision. Astronomers have observed in their entrails protoplanetary disks, brown dwarfs, strong turbulence in the movement of gas particles and photoionizing effects near very massive stars near the nebula. But in the image appear other objects of interest, such as the.....

Welcome to Little Physicians. Let's be friends altogether sharing our interest in Physics whatever you want. Just upload your knowledge. Until now, we have only these categories : astronomy, electronic and electrical engineering, ocean science. You can make a new category if you want.

Then, let's be physicians ourselves.

✨🇲️🇦️🇬️🇮️🇨️🇦️🇱️ 🇺️🇳️🇮️🇻️🇪️🇷️🇸️🇪️ - 1,700 X-ray sources in the Eagle Nebula

The warm outer atmospheres of young stars produce X-ray emission. The dust and gas discs, detectable with infrared observations, surround many young stars. The astronomers used data from the Chandra X-ray Observatory and infrared observations to identify 1,183 young stars in the M16 Eagle Nebula. His work shows that X-ray activity in young stars with discs is, on average, sometimes less intense than in young stars without discs. The Eagle Nebula, also known as Messier 16, contains the young star cluster NGC 6611. It is also the site of the spectacular star formation region known as The Pillars of Creation, which is located in the southern portion of the Eagle Nebula. . Using Chandra, the researchers detected more than 1,700 individual sources of X-rays in the Eagle Nebula. The optical and infrared identifications with stars were used to classify casual intruders in the foreground or in the background, and to determine that more than two thirds of the sources are possible young stars that are members of cluster NGC 6611. The unique capacity of Chandra to solve and locate sources of X-rays allowed to identify hundreds of very young stars, and those that are still in the process of formation, known as protostars. The infrared observations of the Spitzer Space Telescope and the European Southern Observatory indicate that 219 of the X-ray sources in the Eagle Nebula are.....

✨🇲️🇦️🇬️🇮️🇨️🇦️🇱️ 🇺️🇳️🇮️🇻️🇪️🇷️🇸️🇪️ - M92 by Adam Block

Messier 92, also known as NGC 6341, is a globular cluster located in the constellation of Hercules. It was discovered by Johann Elert Bode in the year 1777 and independently rediscovered by Charles Messier on March 18, 1781, who added it to his famous catalog with the number 92. It is located at a distance of about 26,000 light years from Earth, above the galactic plane, so that its visual appearance is less impressive for the photographic image or CCD, however it is visible to the naked eye under exceptionally good conditions. M92 is one of the brightest globular clusters that can be seen in the northern hemisphere, but it is often overlooked by astronomers because of its proximity to an even more spectacular cluster, the M13 globular cluster. M92 has a metallicity, contained in heavy chemical elements, extraordinarily low, approximately one hundredth of the metallicity of the Sun, this could be explained if it were one of the oldest clusters of the Milky Way, since its component stars would only contain hydrogen and helium. The age of M92 can be estimated in some.....
