IC2177 Seagull Nebula (Canis Major)

Lainate, 15 Dicembre 2018
Ultima ripresa della scorsa notte su questa estesa nebulosa situata sul confine tra le Costellazione del Cane Maggiore e quella dell'Unicorno. L'inquadratura (parziale, per le dimensioni della nebulosa) è incentrata sulla testa del Gabbiano.

💫NGC 1068 Winds of Change

This is a composite image of NGC 1068, one of the nearest and brightest galaxies containing a rapidly growing supermassive black hole. X-ray data from the Chandra X-ray Observatory are shown in red, optical data from the Hubble Space Telescope in green and radio data from the Very Large Array in blue. The spiral structure of NGC 1068 is shown by the X-ray and optical data, and a jet powered by the central supermassive black hole is shown by the radio data. The X-ray images and spectra obtained using Chandra's High Energy Transmission Grating Spectrometer show that a strong wind is being driven away from the center of NGC 1068 at a rate of about a million miles per hour. This wind is likely generated as surrounding gas is accelerated and heated as it swirls toward the black hole. A portion of the gas is pulled into the black hole, but some of it is blown away. High energy X-rays produced by the gas near the black hole heat the ouflowing gas, causing it to glow at lower X-ray energies.

This Chandra study is much deeper than previous X-ray observations. It allowed scientists to make a high-definition map of the cone-shaped volume lit up by the black hole and its winds, and make precision measurements of how the wind speed varies along the cone. Using this data it is shown that each year several times the mass of the Sun is being deposited out to large distances, about 3,000 light years from the black hole. The wind likely carries enough energy to heat the surrounding gas and suppress extra star formation. These results help explain how a supermassive black hole can alter the evolution of its host galaxy. It has long been suspected that material blown away from a black hole can affect its environment, but a key question has been whether such "black hole blowback" typically delivers enough power to have a significant impact.

💫IC405 Flaming Star Nebula (Auriga)

Lainate, 12 Dicembre 2018
Altra serata/nottata favorevole, anche se il cielo non è più limpido come nelle sere precedenti, ma comunque più che accettabile.
