The timing of the tick life cycle is why Lyme disease exists, Ostfeld said, and if warming temperatures change the timing, climate change could have a multiplying effect on the spread of the disease.
Like it's sister spacecraft, Voyager 2 also was designed to study the edge of our solar system beyond the planets. Uranus Accomplishments: Following its flybys of Jupiter and Saturn, Voyager 2 was to become the first spacecraft to visit Uranus. Voyager 2 is the only spacecraft to have flown by Uranus. The planet displayed little detail, but gave evidence of an ocean of boiling water about 800 km below the cloud tops.
Uranus and its five major moons are depicted in this montage of images acquired by the Voyager 2 spacecraft. The moons, from largest to smallest as they appear here, are Ariel, Miranda, Titania, Oberon and Umbriel.nglish astronomer William Lassell spotted Umbriel, the darkest of Uranus' big moons, in 1851. In Voyager 2's quick fly-by, scientists were unable to figure out how the surface got so dark, or why there is a bright ring on Umbriel's surface that is 90 miles (140 kilometers) in diameter.
