Topic: Uranus
It is the first time such electromagnetic emissions in the far-ultraviolet have been documented on a celestial object other than a planet or moon. A paper on the findings was released today in the journal Nature Astronomy. ![]() This composite is a mosaic comprising four individual NAVCAM images taken from 19 miles (31 kilometers) from the center of comet 67P/Churyumov-Gerasimenko on Nov. 20, 2014. The image resolution is 10 feet (3 meters) per pixel. (ESA/Rosetta/NAVCAM) «Read the rest of this article» Sections: Technology | No Comments
NASA’s Heatshield for Extreme Entry Environment Technology (HEEET)
NASA needs technology to protect spacecraft as they enter the atmospheres of worlds near and far, from Venus to Uranus. And when we finally bring samples back from places like Mars, NASA needs to ensure those precious pieces of alien worlds are safe as they come back to Earth. «Read the rest of this article» Sections: Technology | No Comments
NASA’s Cassini spacecraft data may hold answers to why Saturn is so Hot
New analysis of data from NASA’s Cassini spacecraft finds a viable explanation for what’s keeping the upper layers of Saturn, and possibly the other gas giants, so hot: auroras at the planet’s north and south poles. ![]() This false-color composite image shows auroras (depicted in green) above the cloud tops of Saturn’s south pole. The 65 observations used here were captured by Cassini’s visual and infrared mapping spectrometer on Nov. 1, 2008.

NASA Scientists take new look at Voyager 2 Data, Find new Discovery about Uranus
Over the next few hours, Voyager 2 flew within 50,600 miles (81,433 kilometers) of Uranus’ cloud tops, collecting data that revealed two new rings, 11 new moons and temperatures below minus 353 degrees Fahrenheit (minus 214 degrees Celsius). The dataset is still the only up-close measurements we have ever made of the planet. ![]() Voyager 2 took this image as it approached the planet Uranus on Jan. 14, 1986. The planet’s hazy bluish color is due to the methane in its atmosphere, which absorbs red wavelengths of light. (NASA/JPL-Caltech) «Read the rest of this article» Sections: Technology | No Comments
NASA’s latest instrument to probe Uranus, Neptune’s Atmospheres
A NASA scientist and his team at the Goddard Space Flight Center in Greenbelt, Maryland, are taking advantage of those advances to mature a smaller, more capable net flux radiometer. This type of instrument tells scientists where heating and cooling occurs in a planet’s atmosphere and defines the roles of solar and internal heat sources that contribute to atmospheric motions. ![]() NASA’s Voyager 2 spacecraft gave humanity its first glimpse of Neptune and its moon, Triton, in the summer of 1989. This image, taken at a range of 4.4 million miles from the planet, shows the Great Dark Spot and its companion bright smudge. These clouds were seen to persist for as long as Voyager’s cameras could resolve them. (NASA) «Read the rest of this article» Sections: Technology | No Comments
NASA’s Voyager 2 Probe leaves Heliosphere, enters Interstellar SpaceNASA Jet Propulsion Laboratory
Members of NASA’s Voyager team will discuss the findings at a news conference at 10:00am CST (8:00am PST) on Monday, December 10th at the meeting of the American Geophysical Union (AGU) in Washington. The news conference will stream live on the agency’s website. ![]() This illustration shows the position of NASA’s Voyager 1 and Voyager 2 probes, outside of the heliosphere, a protective bubble created by the Sun that extends well past the orbit of Pluto. Voyager 1 exited the heliosphere in August 2012. Voyager 2 exited at a different location in November 2018. (NASA/JPL-Caltech) «Read the rest of this article» Sections: Technology | No Comments
NASA explains why it’s important to study Space RocksNASA’s Jet Propulsion Laboratory
Those clues come in the form of asteroids, comets and other small objects. Like detectives sifting through forensic evidence, scientists carefully examine these small bodies for insights about our origins. ![]() The small worlds of our solar system help us trace its history and evolution, including comets.

NASA looks for Water deep in Jupiter’s AtmosphereWritten by Lonnie Shekhtman
But one critical question has bedeviled astronomers for generations: Is there water deep in Jupiter’s atmosphere, and if so, how much? ![]() This visualization was created from images captured by NASA’s Juno spacecraft, which has been studying Jupiter since it arrived there July 4th, 2016.

NASA believes collision caused Uranus to rotate on it’s sideNASA’s Ames Research Center
The research team, led by Durham University, UK, in collaboration with scientists at NASA’s Ames Research Center in Silicon Valley, used advanced computing techniques to create the most detailed simulation to date of the suspected impact. «Read the rest of this article» Sections: Technology | No Comments
NASA detects Hydrogen Sulfide in clouds on UranusNASA’s Jet Propulsion Laboratory
A global research team that includes Glenn Orton of NASA’s Jet Propulsion Laboratory in Pasadena, California, has spectroscopically dissected the infrared light from Uranus captured by the 26.25-foot (8-meter) Gemini North telescope on Hawaii’s Mauna Kea. They found hydrogen sulfide, the odiferous gas that most people avoid, in Uranus’ cloud tops. The long-sought evidence was published in the April 23rd issue of the journal Nature Astronomy. ![]() Arriving at Uranus in 1986, Voyager 2 observed a bluish orb with extremely subtle features. A haze layer hid most of the planet’s cloud features from view. (NASA/JPL-Caltech) «Read the rest of this article» Sections: Technology | No Comments
