It's possibly as big as Manhattan, likely older than our own solar system and it's traveling through space at speeds of up to 153,000 miles per hour. It's also only the third confirmed interstellar object and the second comet from outside our solar system to be identified by humans.

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.

Because this comet is so rare, NASA is utilizing multiple spacecraft and telescopes to observe it. Since its discovery on July 1, twelve NASA missions have already taken pictures of it. More missions will also get a chance to capture it as it continues to move across space.

Collisions with the solar wind would ensure we were well aware of an antimatter comet entering our solar system, explains one reader

Astronomers refute Avi Loeb's 'misinformation' regarding interstellar comet 3I/ATLAS, proving its natural origins despite 'alien' anomalies.

Space agency NASA is monitoring two large bus-sized asteroids passing through Earth this week. NASA is closely keeping a watch on 2051 VPI and 3361 Orpheus amid the growing mystery surrounding interstellar comet 3I/ATLAS.
