Sirius up in the sky

Briefly about Sirius

Another bright star after the Polar Star in the northern hemisphere is Sirius. It is relatively close to our planet and can be easily observed by the naked eye. Sirius sparkles with red, green, white and blue. If you have no tiny idea about its colourful luminosity, you might take it for the lights of a plane blinking in the night sky. However, later you realize that no plane can remain so long at the same position so high above…

How can you find Sirius?

Only 8.6 light years separate us from Sirius. If you know where Orion is located, then it won’t be difficult for you to find Sirius which shines to the southwest of it. Sirius is a part of the constellation Canis Major. The Latin name can be translated as the greater dog. (The smaller one, by the way, can be found in the constellation Canis Minor.)

A binary star system

Actually, Sirius is a binary star system. It means there is Sirius A and Sirius B. They orbit around their centre of mass. Approximately every 50 years these two stars come very close to each other. As a result, both stars begin spinning faster. The energy releases and flows to the Sun which shares it with other planets.

'Siriusly', it's Sirius =)

Sirius and ancient people

Ancient Egyptians associated Sirius with Osiris, the god of the afterlife. The Dogon people, an African tribe, also worshipped Sirius where all souls were thought to be created. The Ancient Greeks also noticed Sirius and had a lot of superstitions, usually very negative ones. Less people know, less positive myths people make up.

I wish I could read a personal profile Love is beautiful - smiling, laughter, a loving thrill of the heart, excitement. However, the fairy tale  requires hard work . What if at a meeting with a new person who could potentially become the love of your life there were opportunities to view his/her personal file, like a profile of a character in a computer game? Could this help later avoid unnecessary acquaintances and any related hassle? For example, the file would introduce not only the positive aspects of a person (loving, tender, great hugger), but also the essence of his daily...
