Image:
This shimmering view of interstellar gas and dust was captured by the European Space Agency’s Euclid space telescope. The nebula is part of a so-called dark cloud, named LDN 1641. It sits at about 1300 light-years from Earth, within a sprawling complex of dusty gas clouds where stars are being formed, in the constellation of Orion.
Self-Replicating Probes Could be Operating Right now in the Solar System. Here's How We Could Look for Them
In 1949, famed mathematician and physicist John von Neumann delivered a series of addresses at the University of Illinois, where he introduced the concept of "universal constructor." The theory was further detailed in the 1966 book, Theory of Self-Reproducing Automata, a collection of von Neumann's writings compiled and completed by a colleague after his death. In the years that followed, scientists engaged in the Search for Extraterrestrial Intelligence (SETI) considered how advanced civilizations could rely on self-replicating probes to explore the galaxy.
