W.M. Keck Observatory has two Telescopes in the Hawaii Island which lies in the middle of the Pacific Ocean.
The two Keck telescopes can see both infrared and visible light. Each telescope has a diameter of 10m and weigh 300 tons. The mirror used is made of 36 Hexagonal segments and a single segment is 1.8m in diameter which is only a little bit greater than the average human height.
Keck1 telescope started observing in May 1993 and Keck2 telescope in October 1996.
A recent science news released by Keck Observatory tells us about a star orbiting the supermassive black hole at the centre of our galaxy, which was thought to be binary. The star named S0-2 is now proved to be single.
The orbit of S0-2 is shown in blue in the image below.
There are several theories which describe how S0-2 can form near the black hole and the theory that S0-2 should be a binary is one of them.
But the news that S0-2 does not have a companion deepens the mystery of its formation.
