NASA revealed more about Oumuamua, a piece of cosmic rock so strange that some scientists suggested that it could be a foreign space ship.
The space agency has revealed that it can not see the object using its Spitzer Space Telescope. And that can reveal important hints about what it is.
Oumuamua passed through the Earth in September 2017, becoming the first known internist who ever came to our solar system from another. During the flight, the scientists rushed to learn more about it, pointing to telescopes and other instruments, trying to learn as much as possible before they disappeared on the other side of the solar system.

30/30 The Chandra Observatory sees the heart in the dark
Spitzer tried to choose a rock in November, about two months after his closest approach. This failed to be seen – but this defeat limits the limits of how large a rock can be, because if it were large enough it would be noticed, according to a new article published in the Astronomical Journal and co-author of the NASA Laboratory's Jet Propulsion scientists in Pasadena, California.
This helps to believe in the theory that a relatively small object is pushed by the gas ejected from the object. This gave the effect of adding thrust while traveling through the solar system, accelerating it.
This strange acceleration of behavior led scientists to suggest that it could be a foreign probe sent by Earth through a distant civilization. An additional drive could be caused by an object acting like a light signal designed to be carried by solar radiation, as Harvard scientists have recently suggested.
An alternative and more accepted theory of frozen gases inside a purged object and pushing it was dependent on Oumuamua being smaller than the typical comets inside our solar system. With the determination that this is probably the case, research seems to suggest that it is less likely that there are foreign spaceships.
"Oumuamua was full of surprises from the start, so we wanted to see what Spitzer can show," said David Trilling, lead author of the new study and professor of astronomy at the University of Northern Arizona. "The fact that Oumuamua was too small for Spitzer to detect him is in fact a very valuable result."
