\n Ever since its discovery in October 2017, researchers have speculated what the interstellar object \u2018Oumuamua is: an alien \u201clight sail\u201d from another civilization; it\u2019s made of something almost unheard of in science<\/a>; others suggest it is a comet or an asteroid.<\/p>\n

A new study now suggests it might be something very common on Earth: a cosmic \u201cdust bunny.\u201d<\/p>\n

The research, published in Astrophysical Journal Letters, theorizes the 900 foot-long cigar-shaped object is comprised of dust fragments from an interstellar comet, which had a chunk of rock broken off. From there, the dust and rock combined and would be \u201cejected\u201d into interstellar space by solar radiation.<\/p>\n

\u201cWe propose that \u2018Oumuamua\u2019s properties could be explained as those of a fractal dust aggregate (a \u2018dust bunny\u2019) formed in the inner coma of a fragmenting exo-Oort cloud comet,\u201d the researchers wrote in the study\u2019s abstract.<\/p>\n

They continued: \u201cSuch fragments could serve as accretion sites by accumulating dust particles, resulting in the formation of a fractal aggregate. The fractal aggregate eventually breaks off from the fragment due to hydrodynamic stress. With their low density and tenuously bound orbits, most of these cometary fractal aggregates are then ejected into interstellar space by radiation pressure.\u201d<\/p>\n

The idea of a \u201cdust bunny\u201d being created from the rock and dust of another comet is similar to another theory put forth earlier this year. In April, another group of researchers suggested \u2018Oumuamua \u2013 which means \u201cpathfinder\u201d or \u201cscout\u201d in Hawaiian \u2013 could have been ripped from a larger object due to gravity from a nearby star.<\/p>\n

No longer observable by telescopes as of January 2018, many have speculated about what \u2018Ouamumua is, as it travel<\/a>ed through the Solar System at 57,000 mph.<\/p>\n

A study published in November 2018 from the Harvard Smithsonian Center for Astrophysics suggested it could be \u201ca lightsail of artificial origin\u201d sent from another civilization.<\/p>\n

The researcher who discovered \u2018Oumuamua, Canadian physicist and astronomer Robert Weryk, said the idea it was from another civilization was just \u201cwild speculation.\u201d<\/p>\n

The mystery about its exact nature deepened in late 2018, when NASA said it had been looking in \u2018Ouamumua\u2019s direction for two months but did not originally see it.<\/p>\n

A second interstellar object, Comet 2I\/Borisov, was discovered in August 2019.\n <\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/div>\n
