Astronomers are investigating a narrowband radio signal detected by China's FAST radio telescope that appears to be coming from the direction of the super-Earth exoplanet K2-155 d, located 238 light-years away. This discovery is exciting for sky-watchers because it highlights the ongoing search for extraterrestrial life and the potential for radio signals to be a key part of that search. The signal's origin is still uncertain, with scientists considering the possibility of earthly radio interference, and further analysis is needed to determine its source.

A new study suggests that the binary star system 70 Ophiuchi, located about 16 light-years from Earth, could support an Earthlike planet. This discovery is exciting for sky-watchers because it brings to life the possibility of finding a planet with conditions similar to those of Earth, but with the unique feature of orbiting two stars. The idea of such a planet is captivating, especially for fans of science fiction, and it may inspire further research into the possibilities of life beyond our solar system. Sky-watchers can look up the 70 Ophiuchi system, although the potential planet itself would not be visible to the naked eye.

A long-standing space weather mystery has been solved, with researchers determining the validity of a reported magnetic storm from 1871. This resolution is significant for sky-watchers because it helps clarify our understanding of historical space weather events, which can inform predictions of future storms. By studying past events, astronomers can better prepare for and track space weather that may impact aurora visibility and other celestial phenomena.

NASA's SpaceX Crew-12 mission is concluding, with the crew set to return to Earth in early October after supporting research on the International Space Station. This mission is significant for sky-watchers because it contributes to our understanding of space and its potential for human exploration. The crew's research has benefits for life on Earth and prepares humans for deep space missions, making their accomplishments a notable step forward in space travel. Sky-watchers can look forward to the crew's return in early October, marking the end of a successful mission.
