Although space related research has come a long way over last couple of years, some of our earliest exploration outside of solar system came thanks to NASA’s probes that were launched in the 1970s. While the Voyager probes have left our solar system, researchers have claimed that the probe will take 20,000 years to reach other star systems.
In a recently published paper, researches sed data from Gaia space Telescope to reveal the estimate. In the paper, researchers Coryn Bailer-Jones and Davide Farnocchia said, “Following their encounters with the outer planets in the 1970s and 1980s, Pioneers 10 and 11 and Voyagers 1 and 2 are now on escape trajectories out of the solar system. Although they will cease to operate long before encountering any stars (the Pioneers already have), it is nonetheless interesting to ask which stars they will pass closest to in the next few million years.”
According to the researchers, the probes will pass Proxima Centauri first as they travel through space. The researchers claimed that Voyager 1 will pass the star system within the next 16,000 years. On the other hand, it will take 20,000 years for Voyager 2 to reach the system.
In addition to this, the Voyager 1 probe will visit several other stars. Among the most notable ones are flare star HD 28343 and Gliese 445. The HD 28343 is type of a star that showcases increased brightness that lasts for only few minutes. Whaile the reasons for such phenomenon are unknown, researchers predict that the flare is probably due to magnetic energy withing their atmospheres.
