WASHINGTON, June 27 (Xinhua) -- An international team of astronomers has found that "'Oumuamua," the first interstellar object discovered within our solar system, is moving faster than predicted, suggesting that it is most likely an interstellar comet instead of an asteroid. The discovery, report...
For astronomers like me, this question has proved tricky — so tricky that we were very nearly fooled when the first recorded interstellar object, named'Oumuamua, was spotted passing through the inner solar system in 2017. Astronomers once thought that any object moving under its own speed, with...
Abraham Loeb, one of the co-authors and chair of the astronomy department at Harvard University, told Xinhua on Tuesday `Oumuamua showed unusual features since its discovery. "These features make `Oumuamua weird, belonging to a class of objects that we had never seen before." ...

observations point to the possibility that other star systems regularly eject small comet-like objects and there should be more of them drifting among the stars. Future ground- and space-based surveys could detect more of these interstellar vagabonds, providing a larger sample for scientists to anal...
The researchers believe the strong gravitational stretching that occurs in these scenarios could explain Oumuamua's long, thin cigar-like shape. The researchers calculated the number of interstellar objects we should see, based on estimates that a star system likely ejects a couple of Earth-masses ...
interstellar dust penetration/ A9600 Solar system A9840B Interstellar matterBecause of the motion of the Sun through the surrounding interstellar medium, interstellar dust particles may penetrate deep into the Solar System. In this paper, we investigate the conditions for this penetration and find ...
Astronomers have spotted two interstellar objects to our solar system in the last two years, and that’s just the beginning. Researchers believe that in the future, we can expect to see several large objects that originated outside of our solar system zipping through it. And there could be ...
