stars: individual (Cygnus OB2 No. 8A)stars: mass lossstars: winds, outflowsX-rays: starsThe Cyg OB2 association contains some of the most luminous OB stars in our Galaxy, the brightest of which are also among the most luminous in X-rays. We obtained a Chandra High Energy Transmission ...
The North America Nebula is an emission nebula located in the constellation Cygnus, near the bright star Deneb. This nebula covers an area more than four times the size of the full moon and makes a great wide-field target thanks to the emission of hydrogen gas, which gives nebulae their re...
TheFireworks Galaxyis an intermediate spiral galaxy in Cepheus. It is approximately 22 million light-years distant. It lies on the border between Cepheus and Cygnus. The galaxy was discovered by William Herschel in September 1798. NGC 7380 is an open star cluster also known as theWizard Nebula...
Cygnus, the Swan, which contains Deneb, will be to the right (eastwards) and Altair will be at about 45 degrees. In the Southern Hemisphere the sky is reversed, so the Summer Triangle points away from the horizon. If one follows the line from Vega to Altair eastwards and passes the ...
Some examples of the names:Denebis Latin fortail(because it marks the tail of The Swan - Cygnus);Antaresis Greek forrival of Mars(because of its red colour);Aldebaranis Arabic foreye of the bull(because it marks the eye of The Bull - Taurus). ...
Deneb will be the Pole Star in the year 9800 AD. It is located at the tip of the Northern Cross asterism made up of the brightest stars in Cygnus, the others being Albireo (Beta Cygni), Gamma Cygni, Delta Cygni, and Epsilon Cygni. The Summer Triangle consists of 3 bright stars – Ve...
