This week's science news includes the potential visibility of comet 'Lemmon', a trio of comets, the explanation of a mysterious glow at the center of the Milky Way , the science behind the perception of time's acceleration with age, and a discussion regarding the possible revival of Neanderthals .
\One of the most exciting astronomical events highlighted is the trajectory of interstellar comet 3I/ATLAS, which is the third interstellar object ever found in our solar system. This comet is remarkable for being the largest, fastest-moving, and potentially the oldest interstellar object ever observed. As 3I/ATLAS approaches its perihelion, the point closest to the sun, on October 29th, it is expected to begin its months-long journey out of our cosmic neighborhood. Newly released images from the National Science Foundation-operated Gemini South telescope in Chile may offer the most detailed view yet of this fascinating celestial body. The images show the comet potentially turning bright green. As 3I/ATLAS approaches the sun, solar radiation will heat the ice on its nucleus, resulting in the expulsion of gas and dust forming a coma and a prominent tail. The comet is expected to release gas at an increased rate as it reaches perihelion, and when it becomes visible again in early November, it may appear brighter and larger than before. Astronomers are preparing to utilize a full array of instruments to study this unique interstellar visitor, hoping to uncover secrets about the galaxy's outer reaches and its distant past. The study of 3I/ATLAS could potentially unlock untold secrets about the origins and composition of interstellar objects, providing valuable insights into the formation and evolution of planetary systems beyond our own.\Furthermore, the news covers other intriguing developments. One involves the discovery of a 2,700-year-old cuneiform text near the Temple Mount, which reveals that the Kingdom of Judah was late in making a payment to the Assyrians. Another noteworthy finding indicates that Neanderthals were more susceptible to lead poisoning than modern humans, offering a possible explanation for an advantage gained by modern humans. This difference in susceptibility might have played a role in the eventual decline of Neanderthals. The exploration into the perception of time's acceleration with age is also another area of interest. Moreover, other comets and the mysteries of our galaxy are under investigation.
