The sun prevents humanity from hearing aliens SETI has probably received signals from aliens hundreds of times, but “space weather” distorts their messages.

New research shows space weather distorts interstellar messages through spectral broadening of radio waves in stellar winds near the source star or Sun, potentially making signals indistinguishable from noise and exp… #aliens #california #mountain_view #ovni #uap #ufo #ufosky #universemagazine #usa

Plasma around stars may hide signals from aliens Among the multitude of signals filling space, it is quite difficult to find artificial ones. One of its characteristics is considered to be the narrowness of the transmission band

Plasma turbulence around stars can scatter and broaden narrow-band transmissions from orbiting planets, reducing their contrast with natural radio noise and potentially masking artificial signals—especially around red dwarfs with turbulent magnetos… #aliens #ovni #uap #ufo #ufosky #universemagazine

Can aliens live on the Hycean planet K2-18b? K2-18b is a so-called Habitable Zone planet located 124 light-years away from us. Scientists are interested in the possibility of life existing on it.

While K2-18b remains a compelling Hycean candidate with a potentially global ocean and CO2- and methane-rich atmosphere, a VLA- and MeerKAT-based technosignature search applying five filtering criteria found no unambiguous narrow… #aliens #ovni #south_africa #uap #ufo #ufosky #universemagazine #usa
