In a recent paper penned by Amri Wandel, the astrophysicist aims to explain why extraterrestrials still haven’t made contact with us here on Earth. Wandel dives into numbers to illustrate “the size and scale of the universe as we understand it today, the probability that life exists on other worlds” and more.

Using a technique called “chromatic filtering,” scientists were able to reveal the animal’s nervous system and brain in an unsegmented head. Not only is this finding …
Macy Huston, a PhD candidate in astronomy and astrophysics at Penn State, and Jason Wright, a professor of astronomy and astrophysics at the university, have penned a thought-provoking essay on technosignatures—or the signs of alien technology that could lead to discovery. Both work on SETI, the search for extraterrestrial intelligence, and have addressed everything from radio waves to megastructures developed by advanced civilizations that harness …
