A new study suggests aliens on neighboring stars may detect Earth's radio broadcasts. The University of Manchester and the University of Mauritius used crowd-sourced data to replicate radio leakage from mobile towers to examine what alien civilizations would detect from close stars like Barnard's star, six light years from Earth. Here's Why NASA Signals May Have Reached Aliens, But It May Take 27 Years to Respond. The Monthly Notices of the Royal Astronomical Society journal reported that only sophisticated civilizations could detect Earth's mobile tower radio leakage. Despite weaker TV and radio transmitters, mobile communication networks are important worldwide. "While each system represents relatively low radio powers individually, the integrated spectrum of billions of th...

Astronomers have known the fate of planets like Mercury, Venus, and Earth when their host stars die, but they have never seen it in space until now. Scientists in Chile used the Gemini South telescope to see a dying star consuming an exoplanet. A extended, low-energy explosion indicated a planet skimming a star. Astronomers have uncovered stars that swallowed planets by doing a post-mortem autopsy on the dead star. The first direct evidence of star-eats-planet was reported in Nature. The group thinks the occurrence will help researchers find more stars eating planets. Earth's projected end is terrible. "Our interpretation…provides evidence for a missing link in our understanding of the evolution and final fates of planetary systems," the scientists said. According to th...
