For those aiming to view the beautiful constellation from the Southern Hemisphere, during the months of July and August, Cygnus can be seen in the north-eastern sky from about 9 — 10 pm as it moves towards west throughout the night. From mid-northern latitudes, the constellation Cygnus rises high into the sky on summer nights.
This means that it is very easy to spot without the worry of obstructions such as trees or neighboring houses. This is one of the many reasons Cygnus is such a popular choice for amateur astrophotography and visual observations through a telescope. Cygnus constellation star map. Sky and Telescope and the IAU.
The Cygnus constellation is associated with several myths. As the race got intense they flew too close to the sun and unfortunately, their chariots burned down. Both of them came crashing back to the Earth. When Cycnus regained his consciousness, he searched around for his dear friend Phaeton and found his dead body at the bottom of the Eridanus River. A star map depicting the Cygnus constellation as a Swan from If Zeus would allow Cycnus to transform into a swan, Cycnus would live only as long as a swan usually does.
The lovers secretly get married which the Goddess does not approve of at all and thus places a river in the sky to keep them apart. This river is our very own galaxy i. Milky Way. The legend goes that every year, in order to rejoin the lovers, all the magpies gather together and form a gigantic bridge over the river. Gienah is an orange giant star that is 62 times brighter than the Sun and has 11 times its radius.
Since Cygnus lies on the plane of the Milky Way, it is rich in deep-sky objects, including two Messier objects. M29 is an open star cluster that contains around 50 stars. M39 is another open star cluster than contains more than 30 stars. Both of these can easily be seen with a pair of binoculars. The North America Nebula is a colorful emission nebula close to the star Deneb.
Cygnus X is a large region of star formation and home of the famous black hole candidate known as Cygnus X Most of these objects can only be seen in large telescopes. You can see it as one star without using a telescope. The apparent visual magnitudes of the stars are 3. Astronomers enjoy viewing this star system as it offers the beautiful contrast of a gold-yellow star and its glorious azure blue companion 4.
It has an apparent visual magnitude of 3. It is times brighter than the Sun and has a radius of Zeta Cygni lies at the tip of the lower wing of the Swan. It also indicates the end of the lower crossbeam of the Northern Cross 5.
Tau Cygni is a double Cygnus star. The main star is a yellow-white subgiant star with an apparent visual magnitude of 3.
The companion star has an apparent visual magnitude of 6. Together, you can see them in dark skies without using a telescope. The star system lies about Tau Cygni is not a definitive star in the Northern Cross. It lies on the lower Cygnus wing 6. Messier 29 is an open cluster in the swan constellation, with an apparent visual magnitude of 7. It lies about 4, light-years away from our Solar System. You can see this deep-sky object with binoculars, but a telescope will give far more exciting views.
The Messier has a triangular shape, with three bright stars marking the corners. Charles Messier discovered the cluster in It lies near the star Gamma Cygni, to the south and east. The estimated age of the cluster is 10 million years.
Messier 39 is a relatively loose cluster. It has 30 confirmed members occupying an area about 7 light-years in diameter 7. NGC is a medium-sized spiral Cygnus galaxy that is super exciting.
It lies about 22 million light-years away from Earth. The galaxy has an apparent visual magnitude of 9. It is close to the galactic plane, obscured by the interstellar matter of the Milky Way. Cygnus X-1, a binary star system that is famous for its strong source of X-rays. It offered the first major evidence for the existence of black holes in the Universe.
Cygnus X-1 lies about 7, light-years from Earth. This is a binary star system, with a primary Cygnus supergiant, HDE It revolves around its companion star every 5. The X-ray emission is thought to be due to matter torn from the primary star that is heated as it is drawn to the black hole 9. If you look at images, you see that its shape closely resembles that of the continent of North America, hence the name! The shape is a massive cloud of dust that obscures the nebula.
The North America Nebula has an apparent visual magnitude of 4. It was discovered by William Herschel in Of interest to astronomers, is the area of great star-formation, known as the Cygnus Wall. In the image of the shape of America, this lies in the region which would be Mexico and Central America The Pelican Nebula is an emission nebula. It has an apparent visual magnitude of 8. The name comes from the fact that its shape resembles a pelican. NASA scientists say that this massive star-forming region will in millions of years, lose its pelican shape and will need a new name.
The nebula lies close to the nearby North America Nebula, separated from it by a large molecular cloud filled with dark dust. In astronomy terms, they are close at about 1, light-years apart. The two nebulae are about 1, light-years apart. The Pelican Nebula lies near Cygnus brightest star, Deneb. It can be found to the northeast of the star Sadr lies at the center of the Northern Cross, or on the back of the swan, between the wings.
The Sadr Region also includes the beautiful Butterfly Nebula, named because its shape resembles a butterfly. Sadr has an apparent visual magnitude of 2. There is an estimated distance of 1, to 5, light-years between the components in the Sadir region Exoplanets are planets that revolve around stars, other than our star, the Sun. Exoplanets excite astronomers as they may offer conditions similar to those in our Solar System, with the possibility of life. It is a Neptune-like exoplanet with a mass of It takes 4.
It lies about light-years away from Earth. Discovery was in This exoplanet excites astronomers as it has an abundance of Helium in its atmosphere. The observations show helium being blasted away from the planet by radiation from its host star. It is a gas giant with a mass of 3. HD is a yellow star that lies light-years away from Earth. It has 2 exoplanets revolving around it. The first is HD b. This gas giant has a mass of 0. The second is HD , a gas giant with a mass of 1.
It takes The exoplanets discovery was in and respectively. Meteor showers occur when Earth crosses the orbital path of a comet. This creates a spectacular show, often known as shooting stars. Meteors are blueish-white with short tails.
This shower is best viewed in the northern hemisphere. Sky Chart of Cygnus Constellation Here we provide a simplified sky chart of the Cygnus constellation. Alternatively it is possible to locate Cygnus in the night sky using our Online Interactive Planetarium.
Cygnus is circumpolar and transits at UTC altitude: The rise and set times provided here are just directional indications and they refer to a point approximately placed at the center of the constellation. In case of very large constellations like Cygnus actually is these times can have little relevance.
