Oumuamua: Nasu reveals more about the mysterious "alien spaceship" asteroid

NASA has revealed more about the ommuahua, a space rock so strange that some scientists have suggested it could be a foreign spacecraft.

The space agency has discovered that the object can not be seen using the Spitzer Space Telescope. And it can reveal important clues about what it really is.

Oumuamua was passed by Earth in September 2017, making the first interstellar visitor ever make its way to our solar system from one another. As they passed, the researchers rushed to learn more about it and pointed to telescopes and other instruments to try to learn as quickly as possible before disappearing from the other side of the solar system.

Spitzer tried to pick up the rock in November, about two months after his closest approach. She could not see it – but this failure limits the size of the rock, because if it were big enough, he would notice, according to a new article published in the journal Astronomical and scientists writing in NASA's Jet Propulsion Laboratory in Pasadena, California.

This helps to lead the theory that the relatively small object is pushed together by a gas that was thrown out of the object. This gave the effect of adding an impulse as it traveled through the solar system, accelerating it.

It was this bizarre behavior that led scientists to claim that it could be a foreign probe, sent on Earth by a distant civilization. The extra propulsion could be caused by the object that works as a spotlight, designed to be conserved by solar radiation, Harvard scientists recently claimed.

The alternative and more acceptable theory of frozen gases within the expelled object and its thrust together depended on omamoa to be smaller than the typical ones in our solar system. With the statement that this is probably the case, the research seems to suggest theories about it being alien spaceships are less likely.

"Omamoa was full of surprises from day one, so we were eager to see what Spitzer might see," said David Trilling, lead author of the new study and professor of astronomy at the University of Northern Arizona. "The fact that Omamu was too small for Spitzer to recognize this is actually a very important result."
