As Oumuamua traveled through our solar system, it didn't follow the normal path of a typical comet under the sun's gravity. Rather, it slightly shifted off course, which couldn't be explained by ...

such as in the case of the interstellar object 1I/2017 U1 ‘Oumuamua. Aside from the effects of outgassing, comet orbits are also constantly changing simply due to the competing gravitational pulls of ...

This artist's impression shows the first interstellar object discovered in the Solar System, Oumuamua. Observations made with the NASA/ESA Hubble Space Telescope, CFHT, and others, show that the ...

They estimate that the number of streams crossed by the Sun and co. is a million or more ... [62 miles], is comparable to the number of 1I/Oumuamua-sized objects in the stream of ISOs originating ...

When studied by a team led by Dr Marco Micheli, part of 'Oumuamua's observed acceleration was best accounted for by the effect of the Sun's heat on its icy surface. Comets consist of both rock and ...

Avi Loeb shares the story of how a Tesla Roadster had some astronomers convinced for a time that they had discovered a new ...

Eventually, the sun will bombard Earth with enough high ... object to pass through our solar system - a rock named "Oumuamua" - was an advanced alien spaceship scouting Earth and nearby planets ...

In a comet’s case, ice turns into gas when heated by the Sun, and that gas escapes into ... the case of the interstellar object 1I/2017 U1 ‘Oumuamua. Aside from the effects of outgassing ...
