Juno snaps images of Jupiter's moons as rendezvous approaches

Like any tourist, Juno is sending back snaps of its journey. The unmanned spacecraft was 6.8 million mi (10.9 million km) from Jupiter when it captured an image of the banded giant planet and its four largest moons, Io, Europa, Ganymede, and Callisto on June 21. The image was taken by the probe's JunoCam, which NASA describes as an "outreach instrument" to increase public participation in the US$1.1 billion mission.Read More

"Lucky imaging" creates fiery composite of Jupiter

At this moment, the Juno spacecraft is hurtling towards Jupiter where it is set to take up orbit on July 4. To help map the planet for that rendezvous, the European Southern Observatory has used an instrument on its Very Large Telescope to create a stunning image of the solar system's largest planet. To bring the image to life, the space agency relied on a technique known as "lucky imaging."Read More

Surprise package: Juno nears rendezvous with Jupiter

On July 4, Americans usually celebrate Independence Day with parades, fireworks and picnics, but this year NASA is adding its own contribution to festivities as the Juno deep space probe becomes just the second spacecraft in history to orbit Jupiter. After a five-year journey, the solar-powered unmanned explorer will autonomously fire its main engine for 35 minutes as it starts a 20-month mission to study the gas giant. What will be found remains to be seen, but if history is any indicator, it's likely to be very unexpected.Read More

Layer of strange "dark hydrogen" believed to exist on Jupiter-like planets

As the most abundant element around and the basis for a full three-quarters the mass of the universe, you'd think scientists would have uncovered all there is to know about hydrogen. Apparently, they haven't, as researchers at the Carnegie Institution for Science have just produced a third version of the element in a lab, that they believe is found on gas giant planets like Jupiter and Saturn. They're calling it dark hydrogen. Read More

Scientists break through the clouds to reveal source of Jupiter's wild weather

The standard image of Jupiter is of a mysterious planet shrouded in colorful strips, spots and swirls. But what exactly is going on beneath the atmosphere's chaotic exterior is a question that has mystified astronomers for some time. Researchers have now peeled back the curtain by producing the most detailed radio map of Jupiter's atmosphere yet, revealing swathes of ammonia gas that drive its stormy weather and possibly, other giant planets just like it.Read More

Solar activity sparks powerful X-ray aurorae on Jupiter

Solar activity can prompt a massive increase in the intensity of Jupiter's polar aurorae, according to a new study drawing on data collected by NASA's Chandra X-ray Observatory. Charged particles from a powerful solar storm were observed creating an impressive light show as they struck the Jovian planet in October 2011.Read More

Juno Jupiter probe sets solar-powered space distance record

NASA's unmanned Juno deep space probe may still be over six months away from reaching Jupiter, but it's already flown into the record books. On Wednesday, January 13 at 2:00 pm EST (19:00 GMT) the planetary orbiter became the most distant solar-powered craft from Earth as it passed a point 493 million miles (793 million km) from the Sun. Juno is the ninth deep space probe to visit the outer Solar System and the first to rely on solar panels for power instead of nuclear generators.Read More
