Some of us may remember the launches of Voyagers 1 and 2 in 1977. They were ambitious missions to fly by the outer planets. Who would have believed that they would still be sending back scientific data from the distant reaches of the sun’s influence?
Voyager 1 has energy to continue its mission until 2025, Voyager 2 until 2020. Voyager 1 is about 146 times further from the sun than the Earth and is the most distant man-made object. Voyager 2 is about 120 times further from the sun than the Earth. Both have reached the interstellar medium and are now providing data that shows information about cosmic rays from interstellar space.We hope you will join us for Public Night at the Observatory the first Friday each month from sunset to 10 p.m. Check out the stars, planets (Jupiter and Saturn), and objects through our large telescopes: humbleisd.net/observatory.
