✨🇲️🇦️🇬️🇮️🇨️🇦️🇱️ 🇺️🇳️🇮️🇻️🇪️🇷️🇸️🇪️ - Markarian 3 by Judy Schmidt

Astronomer Judy Schmidt, presents us with 2 images of the early-type galaxy Seyfert, Markarian 3. In the upper part, the image is from the Hubble Space Telescope, and the lower image is a composition of Hubble images with images from the X-ray Observatory Chandra Astronomers have used these observations to study the active core of this galaxy, which contains an energetic AGN, which is known as a galactic supermassive black hole. A preliminary analysis of the first high-resolution X-ray spectrum of a Seyfert 2 galaxy, Markarian 3, was obtained with the high-speed energy transmission spectrometer on board the Chandra X-ray Observatory. The high-energy spectrum is dominated by the reflection of the continuous radiation of the active galactic nucleus in a cold, optically thick medium and contains bright fluorescent lines of iron and silicon, as well as weak and mixed lines of sulfur and magnesium. The emission of soft X-rays extends spatially along the ionization cone and shows discrete emission signatures after recombination and photoexcitation produced in a warm photoionized region. The measured iron line fluxes indicate that the emission of colliding ionized plasma is almost completely insignificant and does not contribute significantly to the total energy budget of the X-ray emission. We find that significant fractions of the H-type resonance lines are produced. and He, as well as the observed iron L-lines, through re-emission from the warm absorption medium observed in the Seyfert-1 type galaxies. Their spectral X-ray properties are qualitatively consistent with those of a Seyfert galaxy. in a different orientation and provide additional convincing evidence of the existence of a.....

Messier 54, cúmulo globular por ESO.

Esta nueva imagen, obtenida con el telescopio de rastreo del VLT, instalado en el Observatorio Paranal de ESO, en el norte de Chile, muestra una vasta colección de estrellas: el cúmulo globular Messier 54. Se trata de un grupo muy parecido a tantos otros cúmulos, pero éste tiene un secreto: Messier 54 no pertenece a la Vía Láctea, sino que forma parte de una pequeña galaxia satélite, la galaxia enana de Sagitario. Esta diferencia ha permitido a los astrónomos utilizar el Very Large Telescope (VLT) para comprobar si también se encuentran bajos niveles de litio en estrellas que no pertenezcan a la Vía Láctea.

✨🇲️🇦️🇬️🇮️🇨️🇦️🇱️ 🇺️🇳️🇮️🇻️🇪️🇷️🇸️🇪️ - 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.....
