3I/ATLAS is ready for its close-up.

After much anticipation, NASA will release images of Manhattan-sized comet 3I/ATLAS — including the much-awaited HiRISE snaps — as it streaks through our solar system.

Harvard scientist Avi Loeb believes the images could potentially shed light on their artificial origins. “It would be interesting to know if there was any evidence for new objects that either accompanied 3I/ATLAS or came from it towards Mars,” the astrophysicist told The Post in an email. “They could imply an iceberg that breaks up or a mothership [that] releases mini-probes.”

The eye-opening photos, which were taken “during a number of the agency’s missions,” will be unveiled on Wednesday, November 19, at 3 p.m. EST at “NASA’s Goddard Space Flight Center in Greenbelt, Maryland,” the space agency announced in a release.

Meanwhile, virtual stargazers will be able to watch the interstellar unveiling remotely via a livestream on NASA’s YouTube channel.

The agency didn’t specify when the 3I/ATLAS photo-ops were taken or which imagers captured the comet on camera, only disclosing that they were snapped via “spacecraft across the solar system, as well as ground-based observatories” supported by the agency.

However, an agency source told the Post last week that the footage included snaps taken by the Mars Reconnaissance Orbiter’s HiRISE camera as it passed by the Red Planet from Oct.1 to Oct. 7. They were not released because of the government shutdown, which ended late Wednesday.

Loeb likely felt slightly vindicated, having previously accused the agency of holding the photos hostage for “bureaucratic reasons” as a result of the government shutdown, which has since concluded.

“Science should have been prioritized over bureaucracy,” Loeb told The Post last week. “The truth about the nature of 3I/ATLAS will be revealed by the sharing of data, not by the storyline of gatekeepers.”

In addition, the NASA source told the Post that the images are expected to be the highest resolution photos of the object to date.

Loeb was over the moon about the news. In a recent blog post, the researcher said that the photos could potentially provide a clear picture of the comet’s structure, including the nucleus and the infamous anti-tail — which points toward the sun rather than away as is typical of comets.

He said that the HiRISE camera images will be the clearest yet, eclipsing the snaps taken by the Hubble Space Telescope on July 21, which have provided the starkest picture to date.

“The images from the HiRISE camera onboard the Mars Reconnaissance Orbiter would give us a side-view of the anti-tail, as well as a spatial resolution that is 3 times better than that of the Hubble Space Telescope,” Loeb wrote.

“The brightest pixel in the HiRISE image will constrain the nucleus size and reveal the geometry of the glow around it,” Loeb told the Post. He had previously speculated that the center could in fact be nuclear — and possibly an engine crafted by an alien race.

Other possibilities include the aforementioned probes, which he claimed in September could appear as UAPs (unidentified anomalous phenomena).

This would perhaps point to Loeb’s prior theory that 3I/ATLAS — which is the third ever interstellar object recorded in our solar system — is an alien probe sent to spy on him, potentially with hostile intentions.
