In case you missed it, there\u2019s a fascinating object from another part of the universe visiting our neck of the woods.<\/p>\n

Dubbed 3I-ATLAS \u2014 \u201cthree\u201d as in the third known interstellar object from outside of our solar system \u2014 the bizarre entity has had the astronomical community in a quiet fervor since it was first spotted in early July.<\/p>\n

The object is widely believed to be an interstellar comet, although a handful of experts, including Harvard\u2019s ever-controversial astronomy researcher Avi Loeb<\/a>, have suggested that it might be a visitor<\/a> from an alien civilization. Many of Loeb\u2019s peers have dismissed that possibility<\/a>, but that hasn\u2019t quieted the firebrand researcher.<\/p>\n

The object is currently hidden behind the Sun, where it\u2019s slated to remain unobservable from Earth for the better part of a month \u2014 a blind spot that Loeb had already speculated<\/a> the object might use to do something unexpected. Now, the latest images from Nordic Optical Telescope, located in the Canary Islands, have provided him with new fodder.<\/p>\n

Those images suggest that a \u201ctail\u201d of debris the object sprouted<\/a> as it neared the Sun has now changed directions, and is instead facing toward the Sun<\/a>. Astronomers call this an \u201canti-tail,\u201d a phenomenon which has been observed in a number of other comets<\/a> going back decades.<\/p>\n

Anti-tails have a simple explanation: as the object approaches the sun, our relative position<\/a> makes the long trail of particulate appear to flip, when in reality it hasn\u2019t changed. Basically, we\u2019re getting a 3D optical illusion, exacerbated by the Sun\u2019s gravity and our relative position in space.<\/p>\n

Loeb, though, has another explanation. In his latest blog on the interstellar object, Loeb posits that the anti-tail could show an alien craft applying \u201cbraking thrust\u201d \u2014 slamming on the brakes, essentially, as it seeks to prolong its sojourn through our star system.<\/p>\n

\u201cIf the object is an alien spacecraft slowing down, and the anti-tail is braking thrust, then this change from anti-tail to tail would be entirely expected near perihelion,\u201d Loeb wrote, referencing an idea shared by his colleague Adam Hibberd at the Institute for Interstellar Studies.<\/p>\n

\u201cIn that case,\u201d Loeb continues, the \u201ctransition would constitute a technosignature in the form of an unexpected phenomenon indicative of controlled maneuvering, possibly with the intention of achieving a bound heliocentric orbit between Mars\u2019s and Jupiter\u2019s orbits.\u201d<\/p>\n

Either way, it\u2019ll be a while before we know for sure. The object isn\u2019t expected to reappear until December 19, at which point it\u2019ll be clear whether its trajectory has been altered by a braking maneuver \u2014 or if it\u2019s still simply hurtling through space like the inert snowball that most scientists believe it to be.<\/p>\n
