Astronomers searching for signs of life beyond earth have spotted something strange. An as-yet unexplained radio signal appears to be coming from the direction is the closest to the sun – a small red star roughly 4.2 light-years away called proxima centuari.
Adding to the excitement, at least two planets orbit this star, one of which might be temperate and Rocky like Earth. What are the odds that another technological civilization would be located at the very nearest star to us?
With so many billions of stars in our galaxy? The odds seem very much against it, but all we can do is follow tha data and evidence as we learn it. The signal seemingly must either be from proxima centuari, another unrelated source within the beamwidth of the telescope, or from terrestrial interference.
Past experience suggests the third option, but there is still a lot more analysis to be done.
NASA revealed the 18 astronauts names on December 9 at Kennedy space center in Florida. It’s currently targeting a 2024 human landing. Among the astronauts announced today is one of the five NASA crew members currently living and working in orbit.
Kate rubin’s was selected in the astronaut class of 2009 and arrived at the international space station in October for a six-month stint. The fight is her second; she also flew in 2016.
During that mission, Rubin’s became the first Scientist to sequence DNA in orbit. The Artemis astronaut cadre also includes christina Koch, who was selected to train as an astronaut in 2013 and has flown to space once, spending 328 days in the second longest single flight by an American astronaut in 2019 and 2020.
During her time in orbit, she participated in six spacewalks, including three with colleague Jessica Meir that were the first all-woman space walks.
