Während beim etwas helleren Nebel IC 63 der rötliche Emissionsanteil überwiegt, dominieren beim blasseren IC 59 die bläulichen Reflexionsanteile. High overhead in northern autumn evenings lies the W- shaped constellation Cassiopeia, in mythology the Queen and mother to Andromeda, to us brilliant against the background of the Milky Way and fully circumpolar from most of the United States and all of Canada. Während beim etwas helleren Nebel IC 63 der rötliche Emissionsanteil überwiegt, dominieren beim blasseren IC 59 die bläulichen Reflexionsanteile. As a result, its equatorial radius is larger than its polar radius, giving the star a flattened shape. Its brightness has been slowly increasing since to about magnitude 2.2. IC 59 lies a bit farther from the star and shows less hydrogen-alpha emission and more reflected blue light. The open clusters NGC 189 and NGC 129 appear in the area between Gamma Cassiopeiae and its bright neighbour Caph, the rightmost star of the W asterism. Gamma Cassiopeiae does not have a formal name.

No está en la foto pero aun así es posible sentir la fuerte presencia de esta estrella tan béstia (en la parte superior derecha de la imagen) como esa luz azul que va a la nebulosa. The “e” suffix indicates hydrogen emission lines in the star’s spectrum. With an apparent magnitude that varies from 1.6 to 3.0, it sometimes outshines its neighbours Schedar, Caph and Segin to become the constellation’s brightest star. Cassiopeia is one of the 88 modern constellationswe see today. The ultraviolet radiation energizes the electrons within the nebula, and the electrons release the energy as hydrogen-alpha emission, which gives the nebula its red glow. If you would like to get a little bit more serious with this hobby, you would need to have acces to some astronomy equipment and accessories, including telescopes, telescope mounts, eyepieces, filters, and software or star charts.

The colours in the eerie nebula showcase how the nebula is affected by the powerful radiation from the distant star. Gamma Cassiopeiae has a mass 17 times that of the Sun and, as it ended its main sequence lifetime, it has expanded to a size of 10 solar radii. Schedar can be used to find the bright emission nebula NGC 281, popularly known as the Pacman Nebula. The star’s estimated age is only 8 million years. In the late 1930s it underwent what is described as a shell episode and the brightness increased to above magnitude +2.0, then dropped rapidly to +3.4. Even though it is a very young star, Gamma Cassiopeiae has already left the main sequence and begun its death process. astrokuky. For more distant galaxies it might be more than 65 million years so you might be looking at an image when dinosaurs still lived on our planet Earth.

Thanks to astrophotography you can see things not not available to an open eye, a colorfull wonders of the Universe. Since there were no signs of a companion in the spectrum of Gamma Cassiopeiae, the system was adopted as a single-lined spectroscopic binary, that is to say, a system where the spectrum of only one component is seen and the presence of a companion is inferred from spectral lines periodically shifting towards the blue, then towards red and then towards blue again, indicating that the components are moving toward us and away from us, i.e. From Redmond , Gamma Cassiopeiae Nebula is visible all night because it is circumpolar. 99% Upvoted.
