Uranus’ moon Miranda shows signs of past geological activity, with deep canyons and other chaotic terrain. Photo Credit: NASA/JPL-Caltech Seventy years ago, the existence of a new world was added to the growing vault of human knowledge. More than 1.8 billion miles (2.9 billion km) from Earth, circling the gaseous planet Uranus, its small […] 
The Voyager adventure began 40 years ago, today, on 20 August 1977. Image Credit: NASA/JPL-Caltech Forty years ago, today, on 20 August 1977, a space explorer rose from Earth on a multi-decade adventure, which would unveil all four of the Solar System’s giant gaseous planets in unprecedented detail. Despite being originally detailed to visit […] 
Uranus and Neptune: the Solar System’s unique ice giant planets, of which we only got brief glimpses during the Voyager 2 flybys in the 1980s, beckon for further, more detailed exploration. Image Credit: NASA Last year’s historic close flyby of Pluto by NASA’s New Horizons spacecraft put the outer Solar System firmly back in […] 
From NASA: “NASA’s Juno spacecraft captured this view as it closed in on Jupiter’s north pole, about two hours before closest approach on Aug. 27, 2016.” Image Credit: NASA/JPL-Caltech/SwRI/MSSS Jupiter, with its complex layers of clouds and storms, is revealing itself to be a multifaceted jewel of a planet. Over forty years after […]

Image Credit: NASA At 12:59 p.m. EST (5:59 p.m. GMT) today, exactly three decades passed since NASA’s Voyager 2 spacecraft became the first machine fashioned by human hands to visit Uranus, the seventh planet in line from the Sun. […] 
Visible only as a crescent, Uranus recedes from Voyager 2 in the days after Closest Approach. Photo Credit: NASA Thirty years ago, today and tomorrow, NASA’s Voyager 2 spacecraft gave humanity its first close-up glimpse of Uranus. Known for more than two centuries, and frequently the “butt” of many off-color jokes, this giant gaseous […] 
Uranus (left) and Neptune (right). These two ice giants and their many moons are awaiting further exploration. Image Credit: NASA The outer Solar System has been a busy place lately, with the ongoing Cassini mission at Saturn and New Horizons’ recent spectacular flyby of Pluto. Literally in-between those two worlds, however, it has been […] One Day to Pluto: Looking Back at Humanity's First-Time Successful Encounters With the Sun's PlanetsTomorrow’s historic flyby of the dwarf planet Pluto and its binary companion, Charon, will mark the completion of humanity’s first-time exploration of each of the Solar System’s nine traditional planets. Photo Credit: NASA Tomorrow, the United States will become the first nation to have conducted a close-range reconnaissance of all nine “traditional” planets in […] A computer-generated impression of the view from the surface of Pluto. The Sun looks like a very bright star on the sky (upper right), while Charon, Pluto’s biggest satellite, looms large near the horizon (at left). The scientific study of the Pluto-Charon system, has been one of expanding horizons and increased awareness of our […] A series of images of Uranus and Neptune that were taken with the Hubble Space Telescope. The top row reveals the ice giant planets in natural colors, showing the planets as they would appear if we could see them through a telescope. The images at the bottom were taken with certain types of different […] |
