NASA will reveal new imagery of the interstellar comet 3I/ATLAS on Wednesday (Nov. 19), and you can watch it live. The 3I/ATLAS photos, which were "collected by a number of the agency's missions," according to a statement NASA posted on Monday afternoon (Nov. 17), will be unveiled during a press conference on Wednesday at 3 p.m. EST (2000 GMT).

As far as physical features, NASA says 3I/ATLAS has speed, color, and direction that are, “consistent with what we’d expect from a comet.” It has an icy nucleus and a coma—a bright cloud of gas and dust that surrounds the comet. That coma is emitted at increasing rates as the comet approaches the sun.

Harvard scientist Avi Loeb speculated that NASA’s recently released photos of 3I/ATLAS could potentially point to its artificial origins — and even wondered if the so-called comet was purposely targeting and sweeping meteorites out of its path. He posited his theory in a viral new blog post on Medium.

ESA's ExoMars orbiter has tracked interstellar comet 3I/ATLAS at unprecedented speed, refining its trajectory and offering vital lessons for planetary defence.

The new study involved taking a fresh look at the "Altamura Man," which is an exceptionally well-preserved Neanderthal skeleton covered in a thick layer of calcite, sometimes called "cave popcorn." The researchers' findings suggest that the size of Neanderthal noses might not have had anything to do with living in cold temperatures.
