Oumuamua is the first confirmed interstellar visitor to our solar system, which sparks curiosity and debate among scientists. Tap to know more about it.
Because ‘Oumuamua — named after a Hawaiian word for “visitor” and designated 1I as the first interstellar object found — is unique and tantalizing for many reasons.
We find that ‘Oumuamua was small, with dimensions 45 m × 44 m × 7.5 m at the time of observation at 1.42 au from the Sun, with a high albedo of 0.64. This albedo is consistent with the N2 ...
Unidentified interstellar visitor 'Oumuamua might be a comet that lost its tail after being hit by the sun's cosmic rays.
But Oumuamua was too small to have any surface dust—denying it the glowing halo, or coma, that circles the body of common comets as well as creating the comet’s characteristic tail.

The controversy is not likely to evaporate anytime soon. Avi Loeb, an astronomer at Harvard who has proposed that Oumuamua could have been a light-sail or some other alien artifact, was quick to ...
The strange outer-space object 'Oumuamua, which flew through our solar system in 2017, wasn't a spaceship. Scientists now have a simple explanation.
Scientists have a new idea to explain the strange behavior of ‘Oumuamua, our solar system’s first known interstellar visitor. In October 2017 astronomers first spotted the object by chance as ...
‘Oumuamua’s Bizarre Acceleration May Have Been Caused by Hydrogen, Not Alien Technology According to a new paper, a perplexing interstellar object was just a comet sweating hydrogen.
Astronomers later confirmed that 'Oumuamua was the first object ever detected to have visited our solar system from another star. But almost as soon as the object had arrived, it was on its way ...
