NASA is at present using its Spitzer Space Telescope to study an object named “‘Oumuamua” which is one of the first interstellar objects known to have visited the solar system. The researchers are now making use of the infrared rays to analyze the ‘Oumuamua via the Spitzer telescope just immediately after being spotted in our system. The telescope has shown the object to look faint prior to its closest approach to the Earth. Thus, this puts a new thought about how large can the object actually be.
The size has been found to be consistent according to the studies and the gassing out has been misjudged to be the reason for the change in speed and direction of the ‘Oumuamua that had taken place last year. The gas being given out was gently pushing the object owing to its smaller size in comparison to the general comets found in the solar systems. The new object has thus been found to compose a lot of frozen gas exactly as the comets. The novel object has been a surprise package from the very beginning even though it has been an object difficult to spot owing to its tiny structure. The ‘Oumuamua was identified by Pan-STARRS 1 telescope of the University of Hawaii prior to the Spitzer’s tracking. The sunlight’s reflection and infrared energy have helped the multiple ground-based telescopes and NASA’s Hubble Space Telescope prove the ‘Oumuamua elongated dimension and optical observations.
The Spitzer helped study the object dimensions, size, composition, and spherical nature. The ‘Oumuamua has a very reflective surface which is commonly known as the albedo. This character changes as it gets closer to the sun and melts the entire frozen gases, sweeps dust, warms the ice, and make the surface more reflective. It has been orbiting in the interstellar space for a long period of time but has been spotted only lately. ‘Oumuamua is under the scanner of the existing telescopes owing to its diversifying characteristics. According to astrophysicist Jamie Holder and doctoral student Tyler Williamson from the University of Delaware identified a peculiar pair of gravitationally correlated stars known as the “gamma-ray binary system” wherein a massive star system is being orbited by a neutron star and it’s an once-in-a-lifetime experience.
