The Milky Way is probably full of dead civilizations
Most of the alien civilizations that ever dotted our galaxy have probably killed themselves off already. It says where and when life is most likely to occur in the Milky Way, and identifies the most important factor affecting its prevalence: intelligent creatures' tendency toward self-annihilation. "Especially since the Hubble Space Telescope and Kepler Space Telescope, we have lots of knowledge about the densities [of gas and stars] in the Milky Way galaxy and star formation rates and exoplanet formation ... and the occurrence rate of supernova explosions. In other words, we're likely a frontier civilization in terms of galactic geography and relative latecomers to the self-aware Milky Way inhabitant scene. Even an extraordinarily low chance of a given civilization wiping itself out in any given century — say, via nuclear holocaust or runaway climate change — would mean that the overwhelming majority of peak Milky Way civilizations are already gone.space.com

Astronomers see possible hints of life in Venus's clouds
Astronomers have found a potential sign of life high in the atmosphere of neighboring Venus: hints there may be bizarre microbes living in the sulfuric acid-laden clouds of the hothouse planet. They said it doesn't satisfy the “extraordinary claims require extraordinary evidence" standard established by the late Carl Sagan, who speculated about the possibility of life in the clouds of Venus in 1967. “It’s not a smoking gun," said study co-author David Clements, an Imperial College of London astrophysicist. After three astronomers met in a bar in Hawaii, they decided to look that way at the closest planet to Earth: Venus. ... Not a single process we looked at could produce phosphine in high enough quantities to explain our team’s findings.”That leaves life.
