To find alien life in our universe, scientists have considered searches for optical lasers or even giant energy-harvesting structures known as Dyson spheres. Now they’re suggesting a more mundane sort of search, a hunt for air pollution in exoplanet atmospheres. Source: https://earthsky.org/space/can-pollution-help-us-find-alien-life…

Search for ETs among 10 million stars comes up empty
Astronomers used a radio telescope in Australia to search for artificial radio signals among 10 million stars. The search came up empty. But, they say, that’s not bad news for those hoping to find intelligent extraterrestrials. Source: https://earthsky.org/space/search-for-extraterrestrial-intelligence-10-million-stars…
Astronomers Find No Signs of Alien Tech After Scanning Over 10 Million Stars
A new large-scale survey of the sky looked into the dark forest of the cosmos, examining over 10 million stars, but failed to turn up any evidence of alien technologies. CNET reports: The study, published in Publications of the Astronomical Society of Australia on Monday, details a search for extraterrestrial intelligence (SETI) using the Murchison Widefield Array (MWA), a collection of…

Exoplanet-hunter TESS completes its primary mission
NASA’s 2nd planet-hunter, TESS, has spent 2 years surveying the sky for exoplanets orbiting distant stars. It has found over 2,000 exoplanets so far. TESS now moves into its extended mission phase. Source: https://earthsky.org/space/exoplanet-hunter-tess-completes-primary-mission…
How many ETs are in our galaxy? Ask the Alien Civilization Calculator

New Exotica Catalog will help guide search for ET
“What if extraterrestrial intelligences are not like us, but are found in the frigid reaches of the outer solar system, the extreme gravity of neutron stars, the brilliant cores of active galaxies, or the hearts of the richest galaxy clusters?” Source: https://earthsky.org/space/the-breakthrough-listen-exotic-target-catalog-seti-extraterrestrial-intelligence…
Breakthrough Listen releases catalog of “Exotica” – objects of interest as “technosignatures”
Breakthrough Listen, the initiative to find signs of intelligent life in the universe, today released an innovative catalog of “Exotica”—a diverse list of objects of potential interest to astronomers searching for technosignatures (indicators of technology developed by extraterrestrial intelligence). The catalog is a collection of over 700 distinct targets intended to include “one of everything” in the observed universe—ranging from comets…
