CONSTELLATIONS :
If you look in the sky year after year, you will see that stars do indeed appear fixed relative to each other. Furthermore, throughout the year each night the entire pattern of stars appears to rigidly orbit the Earth. If you gaze at the sky on a clear, dark night you will able to notice this patterns, technically called "Asterisms", formed by bright stars. These recognizable patterns of stars are informally called "constellations". The celestial sphere (click the link) is divided into 88 constellations of different sizes and shapes. The boundaries of the constellations are straight lines that meet at right angles.
ZODIAC CONSTELLATIONS:
The constellations through which the Sun moves throughout the year as it travels along the ecliptic are called "Zodiac constellations". We cannot see the stars of these constellations when the Sun is among
them, but we can plot the Sun's path on the celestial sphere to determine through which constellations it moves. Basically, there are 12 zodiac constellations whose borders were set in antiquity. Later astronomers confirmed that there were 13 constellations through which the Sun moves throughout the year. In this list, you will find all the 13 zodiac constellations and the time when the sun passes through them.
In this section, we gonna talk about the basic constellations that we always see by our naked eyes. some of the well-known constellations are "Orion", 'Ursa Major", "Scorpius", "Ursa Minor" etc
CONSTELLATIONS USED IN NAVIGATING OTHER STARS:
From the ancient time before the invention of compass, people use the constellations in navigation. Constellations can be used to find other stars too.
🎵 BIG DIPPER: If you live in northern hemisphere, you can use the Big Dipper to find the north direction by find out the North Star. To do this, at first locate the Big Dipper. if you see the dipper upside down in the sky, imagine the dipper resting on an upside-down table above it. Locate the two stars of the
bowl farthest from dipper's handle. They're called "pointer Stars". Connect the pointer stars by a line and take it away from the table, the first bright star you see is "Polaris". It's also known as "North Star" because it's located almost over the North Pole. So you can easily find North Star like this. North Star is widely used in navigation. Whenever you face Polaris or North Star, you are actually facing north. East is then on your right, south is behind you and west is on your left side.
Now being familiar with Big Dipper, you also easily can locate other stars. Imagine, you gripped the handle of the Dipper and slammed its bowl straight down, the first group of bright stars you encounter will be "Leo". The brightest star in this group is Regulus.
🎵 WINTER TRIANGLE: Winter Triangle connects 3 bright stars of the constellations of "Orion",Sirius". While you're facing the Orion locate it's belt, follow the mental line from it to the left, the first bright star that you will encounter is the brightest star in the sky "Sirius".
"Canis Major", "Canis Minor". You can observe this triangle during the winter months in the northern hemisphere. It passes the sky at night during the middle of the winter.If you able to find the winter triangle, you can also encounter the Orion. It will be easy for you then to find the brightest star in the sky "
🎵 SUMMER TRIANGLE: The "summer triangle" graces the night sky in summer. It connects 3 bright stars of the constellations of "Lyra", "Cygnus", "Aquila", names of the stars are "Vega", "Deneb", "Altair" from the 3 constellations respectively. A conspicuous portion of the Milky Way forms a beautiful
background for these constellations, Which are nearly overhead during the middle of the summer at midnight.
These are some examples which are used to detect other stars or in navigation. apart from these there are some constellations which are very large like "Ursa Major", which can describe an entire area of the sky and all the object in it.
