One day humanity might journey to new worlds and settle them, or discover life already on them, but first we’ll have to find those exoplanets under aliens suns.

Can humanity last another 400,000 years? We might have to if we want to talk to another technological civilization.

If there are so many galaxies, stars, and planets, where are all the aliens, and why haven’t we heard from them? Those are the simple questions at the heart of the Fermi Paradox. In a new paper, a pair of researchers ask the next obvious question: how long will we have to survive to hear from another alien civilization?

Their answer? 400,000 years.

China’s Zhurong rover found geologically recent water on Mars, billions of years after it should have been gone.

This week’s “Heard in the Milky Way” offers audio and video talks and interviews with leading astronomers and astrophysicists that range from Would Data from an Alien Intelligence be Lethal for Us to Neal Stephenson on Sci-Fi, Space, Aliens, AI and the Future of Humanity to Is Alien Life Weirder than We Think, and much more. This new weekly feature, curated by The Daily Galaxy editorial staff, takes you on a journey with stories that change our knowledge of Planet Earth, our Galaxy, and the vast cosmos beyond.

“In light of significant efforts being taken toward manned deep space exploration, it is of high technological importance and scientific interest to develop the lunar life support system for long-term exploration. Lunar in situ resource utilization offers a great opportunity to provide the material basis of life support for lunar habitation and traveling. Based on the analysis of the structure and composition, Chang’E-5 lunar soil sample has the potential for lunar solar energy conversion, i.e., extraterrestrial photosynthetic catalysts. By evaluating the performance of the Chang’E-5 lunar sample as photovoltaic-driven electrocatalyst, photocatalyst, and photothermal catalyst, full water splitting and CO₂ conversion are able to be achieved by solar energy, water, and lunar soil, with a range of target product for lunar life, including O₂, H2, CH4, and CH3OH. Thus, we propose a potentially available extraterrestrial photosynthesis pathway on the moon, which will help us to achieve a “zero-energy consumption” extraterrestrial life support system.”

Chang’E-5 lunar soil was used as the lunar extraterrestrial photosynthetic catalyst for water splitting and CO₂ conversion. Solar energy and water were converted into a wide range of valuable products for lunar life support, including O₂, H2, CH4, and CH3OH. A “zero-energy consumption” extraterrestrial life support system was thus proposed.

A recent study of Jupiter’s moon, Europa, showed that radiolytic oxidants made at the surface of its ice can travel to the ocean beneath its ice shell, according to a team of researchers led by the University of Texas at Austin. This means that the icy moon could be suitable for alien life.

Science Fiction often shows us alien civilizations so advanced they are godlike, but how realistic are they, and what would such entities be like?

Consciousness defines our existence. It is, in a sense, all we really have, all we really are, The nature of consciousness has been pondered in many ways, in many cultures, for many years. But we still can’t quite fathom it.
