WONDER SPACE OBJECT --- OUMUAMUA

 

WONDER SPACE OBJECT --- OUMUAMUA

     On 19^th October 2017 a wonder space object was detected by Robert Weryk using the pan-starrs telescope at Haleakala Observatory Hawaii. It was close to the Sun on 9^th September. When it was first observed it was about 33 million k m away from the Earth. It is about 400 meters long and is about 10 times longer than its width. It was moving at a speed of about 90 k m per second.

     It is not possible to specify whether it is a space object or a space ship sent by super intelligent aliens. It has no similarity to comets or asteroids of solar system. It has no tail like comets and it has no similar dimensions of asteroids. It is more elongated than the asteroids of solar system. Its speed is also enormous compared with objects of solar system. It is not only spinning but also tumbling. It has non-gravitational acceleration. It is understood that the object does not belong to solar system.  It seems it has circulated Milky Way galaxy several times and thus may have originated from entirely different part of Milky Way galaxy several billions of years ago.

     On observation it seems to be coming from the direction of star Vega in the northern constellation of Lyra. As it leaves the solar system in the year 2022 it will head for the constellation Pegasus. Each star has many asteroids of different sizes at the end of its gravitational pull. For example our Sun (star) has oort cloud very far away from the Sun where its gravity is very much less. Due to enormous speed of these asteroids some may go out of the gravitational control of their star and wander in the space. There may be many such asteroids. Scientists expect about 50 such interstellar objects spanning at least 50 miles across in our solar system at any given time. Interstellar objects have greater speed than the objects of our solar system.

     21/Borisov another interstellar object was discovered on 30^th August 2019 and was soon confirmed to be interstellar comet. It arrived in the direction of constellation Cassiopeia. The object was close to the Sun on 8^th December 2019.

     But the appearance and the size and movement etc. of Oumuamua is entirely different from that of 21/Borisov. The present technology of ours is quite insufficient to recognize the interstellar object Oumuamua correctly. But our technology is fast improving and in near future we may be able to recognize any such object correctly whether it is a space object only or a space ship of aliens. For the present some scientists assume it as a space ship of aliens, while majority of scientists consider it as a space object wandering in Milky Way galaxy since billions of years.
