NASA's highly anticipated comet 3I/ATLAS images have been released, with a space agency official shooting down alien rumors and stressing that the interstellar visitor is a comet.

The space agency has called a press conference for 8pm GMT to share new images of 3I/Atlas. Some experts claim it is a comet, but others argue it is a spaceship

Is the viral 3I/Atlas leaked photo real or fake? A clear fact check on its origin, what NASA data show, why basic optics say no, and how social media fueled the debate.

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.
