Stars and the Milky Way

... • It is called the Milky Way because when astronomers looked up at the sky, they saw a line of light that looked like some milk had been spilt. • Stars in our Milky Way can be white, yellow or red. White stars are the hottest and red are the coolest. • It takes light over 100,000 years to travel fro ...

... If you see spectra of our sun then you would notice that green light is mostly emitted by it. Thus, the sun is also white. Stars of more mass to appear blue and less mass appear less. If talking about our solar system, some people say that Jupiter is a failed star. This means that, Jupiter was in th ...

Cygnus (constellation)



Cygnus /ˈsɪɡnəs/ is a northern constellation lying on the plane of the Milky Way, deriving its name from the Latinized Greek word for swan. The swan is one of the most recognizable constellations of the northern summer and autumn, it features a prominent asterism known as the Northern Cross (in contrast to the Southern Cross). Cygnus was among the 48 constellations listed by the 2nd century astronomer Ptolemy, and it remains one of the 88 modern constellations.Cygnus contains Deneb, one of the brightest stars in the night sky and one corner of the Summer Triangle, as well as some notable X-ray sources and the giant stellar association of Cygnus OB2. One of the stars of this association, NML Cygni, is one of the largest stars currently known. The constellation is also home to Cygnus X-1, a distant X-ray binary containing a supergiant and unseen massive companion that was the first object widely held to be a black hole. Many star systems in Cygnus have known planets as a result of the Kepler Mission observing one patch of the sky, the patch is the area around Cygnus. In addition, most of the eastern part of Cygnus is dominated by the Hercules–Corona Borealis Great Wall, a giant galaxy filament that is the largest known structure in the observable universe; covering most of the northern sky.
