In the Northern sky is the beautiful constellation named Corona Borealis. six of its stars form a neat semicircle thet is easy to recognise. The brightest star of this constellation is called GEMMA. It looks like a jewel in the crown. Corona Borealis culminates at around 9:30 p.m. during the first of July.
The southernmost zodiacal constellation of the night sky is the Scorpio or the Vrischika (Indian Name). When it is fully up, it is a beautiful sight and is easy to recognisre. We can identify it by the brightest star named Antares (mag. 0.99). Antares is 30,00,000 times larger than our sun!!!! Fortunately it lies about 425 light years from us. To find Antares we have to face South with Corona Borealis directly overhead. In the first week of July the whole constellation is up in the sky at around 9:00 p.m.
If we look to the east of Scorpius while facing the South we may spot the Sagittarius constellation. It's some of it's stars form the distinctive teapot shape. The brightest star of this constellation is the Kaus Australis. As the brightest part of the Milky Way pass through this constellation, it is richly composed of faint stars and clusters. Sagittarius culminates around 9:00 p.m. during the third week of August.
From Sagittarius if we look towards the northern sky , we may spot a bluish white star named VEGA (mag. 0.04). It is the brightest star in the constellation Lyra or the Harp. The star VEGA fifth brightest star of the night sky. If we look carefully, we may spot one triangle and one small parallelogram. The opposite star of VEGA is a brilliant multiple star. If we look through a small pair of binoculours we may spot two separate stars. It is a unique example of multiple star. Another interesting object of the constellation is the Ring nebula or M57. It can be spotted between the stars of the parallelogram. If we look through a pair of powerful binoculours it can offer us hours of interesting view. Lyra culminates around 9:00 p.m. during the third week of August
To the east of Corona Borealis we can see the constellation Hercules. It is a very large constellation consisting of 200 stars but none of the star is brighter than magnitude 3. The head of the Hercules is made up of a red giant star named Ras Algethi. It has a diameter of at least 45,000,000,000 kilometers which makes it the largest knowing star. Another interesting object of the constellation is the globular cluster named M13. It is 34,000 light years from us and consists of more than 500,000 stars!!! A pair of high powered binoculars reveal many tiny dots. Hercules culminates around 9:00 p.m. during the third week of July.
