Interstellar Object 'Oumuamua' Appears To Be Wrapped In An Organic Insulation Layer

dryriver writes: Oumuamua is the cigar-shaped object -- about 400 meters long and only 40 meters in the other dimensions -- that originated from somewhere else in the Galaxy and visited our Solar system while moving at nearly 130,000 miles per hour. Scientists do not know where Oumuamua came from or what it is made of -- it is not shaped like commonly seen asteroids, and unlike comets, it does not leave a trail behind it, not even when it flew past the Sun. Oumuamua seems to be wrapped in a strange organic coat made of carbon-rich gunk that it likely picked up on its long travels through space. The coat, which gives Oumuamua a dark red appearance according to scientists, was examined by using spectroscopy, which looks at the light being reflected from its surface and splits it down into its wavelengths. By looking at those measurements, scientists can work out what the object might be composed of. Scientists regard it as likely that Oumuamua may be of icy composition on the inside, but that the ice doesn't come off the object due to the thick organic crust that is wrapped around it. Oumuamua has also got extraterrestrial watchers excited. Some believe that its strange, long shape suggests that it is a spaceship of some sort passing through our Solar system. Whatever Oumuamua turns out to be, it certainly has researchers and space watchers around the world fascinated and puzzled at the same time.
