Aliens Might Have Their Radio Signals Blurred By Their Star's Solar Wind

Back in the early 2000s, my computer screen, like that of many other space enthusiasts, was typically covered in a series of rainbow-colored spectral signals. As my computer crunched through thousands of data points of radio signals collected by the SETI@Home initiative, I was hoping I was in some small way contributing to one of humanity’s greatest scientific endeavours - the search for extraterrestrial life. But, according to a new paper published in The Astrophysical Journal by Vishal Gajjar and Grayce Brown of the SETI Institute, it seems unlikely that the signals SETI@Home was tailored to look for actually exist. That doesn’t mean there weren’t aliens yelling into the void at the top of their electronic lungs, but simply that the space weather from their local star might have changed the signal to make it unrecognizable by the time it reached us.
