Earlier this week, NASA officials released long-delayed images<\/a> of interstellar visitor 3I\/ATLAS.<\/p>\n

One of the shots, taken by the HiRISE camera attached to the agency\u2019s Mars Reconnaissance Orbiter, shows the mysterious object blazing past the Red Planet in early October. The image shows a \u201cfuzzy white ball,\u201d per NASA associate administrator Amit Kshatriya, which is being lit up by the Sun \u2014 a \u201ccloud of dust and ice called the coma, which is shed by the comet.\u201d<\/p>\n

The image was our closest look at the object yet, and was taken from a mere 19 million miles away, with a resolution of around 19 miles per pixel.<\/p>\n

And according to Harvard astronomer Avi Loeb, who has long proffered the far-fetched theory that 3I\/ATLAS could be an alien spacecraft visiting the solar system<\/a>, there\u2019s something off about the latest image. (NASA has yet to release its own closer analysis of the HiRISE data, though it\u2019s pushed back against Loeb\u2019s theorizing<\/a>, saying the overwhelming evidence points to it being a natural comet, though a very unusual one.)<\/p>\n

For his part, Loeb says there\u2019s something strange about the jets emanating from the object<\/a>, which appear to be pointing in the direction of motion, not in the direction of the Sun, as previously identified in Hubble Space Telescope data<\/a>.<\/p>\n

\u201cIt is easy to explain a plume of gas and dust extended towards the Sun as a result of the illumination of pockets of ice by sunlight or away from the Sun as a result of radiation pressure or the solar wind,\u201d he wrote in a blog post<\/a>. \u201cIt is also possible to explain a trailing stream that the object leaves behind as the drag on the solar wind slows it down relative to the object.\u201d<\/p>\n

\u201cBut it is much more difficult to account for a plume extended perpendicular to the direction of the Sun and ahead of the object,\u201d he concluded.<\/p>\n

While Kshatriya appears to have vexed Loeb<\/a> by opening Wednesday\u2019s announcement livestream with an outright denial of any fringe theories that suggest 3I\/ATLAS is anything but a natural comet, the Harvard astronomer is still holding onto his guns.<\/p>\n

\u201cCould this be a technological signature of illuminating or clearing the path from any hazardous micrometeorites that may cause damage to a technological object?\u201d he pondered of the counterintuitive plume.<\/p>\n

Fortunately, 3I\/ATLAS is expected to make its closest pass of Earth on December 19, allowing ground- and space-based telescopes to once again take a closer look, allowing us to \u201ccharacterize the jets of 3I\/ATLAS by measuring their composition, speed and mass loading rate,\u201d per Loeb.<\/p>\n

Doing so could finally convince Loeb that 3I\/ATLAS is either a natural comet from a different star system \u2014 or an alien mothership that may or may not pose an existential risk to humanity.<\/p>\n

\u201cThese details will inform us without a doubt whether the jets are produced by natural pockets of ice that are warmed by sunlight or by technological thrusters,\u201d Loeb wrote.<\/p>\n
