Aug 25, 2023 · Ever since Voyager 2 flew past Neptune in 1989, the giant dark smudges that appear in the distant planet's atmosphere have presented a strange puzzle. Now, for the first time, we have observed one with Earth-based instruments in unprecedented resolution, helping scientists figure out why those patches appear so dark and why they are so different from spots on other planets.
Plot 1 is viewed from the north ecliptic pole, to scale. Plots 2 to 4 are third-angle projections at 20% scale. In the SVG file, hover over a trajectory or orbit to highlight it and its associated launches and flybys. Voyager 2 is a space probe launched by NASA on August 20, 1977, as a part of the Voyager program.
Nov 14, 2024 · Credit: NASA/JPL-Caltech. Now, new research analyzing data from that 38-year-old flyby has shed light on this mystery, revealing it was likely due to a cosmic coincidence. Just days before Voyager 2’s flyby, an unusual space weather event compressed Uranus’s magnetosphere, dramatically altering the planet’s magnetic field and creating the ...
Nov 13, 2024 · After traveling some 1.8 billion miles to reach Uranus 38 years ago, Voyager 2 gathered its data on the planet in less than six hours, discovering ten new moons and two rings alongside the void ...
Aug 26, 2019 · In the summer of 1989, NASA’s Voyager 2 became the first spacecraft to fly by Neptune, its final planetary encounter. Managed by the Jet Propulsion Laboratory in Pasadena, California, Voyagers 1 and 2 were a pair of spacecraft launched in 1977 to explore the outer planets. Initially targeted only to visit Jupiter and Saturn, Voyager 2 took ...
The Small Dark Spot, sometimes also called Dark Spot 2 or The Wizard's Eye, was an extraterrestrial vortex on the planet Neptune. [1][2] It was the second largest southern cyclonic storm on the planet in 1989, when Voyager 2 flew by the planet. When the Hubble Space Telescope observed Neptune in 1994, the storm had disappeared.
