    The original plans for the Juno mission to Jupiter didn’t include a color camera. You don’t need color images when the mission’s main goals are to map Jupiter’s magnetic and gravity fields, determine the planet’s internal composition, and explore the magnetosphere. But a camera was added to the manifest, and the incredible images from the JunoCam have been grabbing the spotlight. ... Hundreds of ‘amateur’ image processing enthusiasts have been processing raw data from the JunoCam, turning them into stunning images, many reminiscent of a swirling Van Gogh ‘starry night’ or a cloudscape by Monet. ... Many of the images...

    Yet another Jovian fireball? On May 26th, amateur astronomers recorded a rare impact flash in Jupiter's north polar region. Jupiter just got beaned for the sixth time (that we know about)! On the evening of May 26th, between 19:24.6 and 19:26.2 Universal Time, Sauveur Pedranghelu, a French amateur from Corsica, detected an impact flash live on video in Jupiter's north polar region. The flash was very brief, lasting only about 0.7 second, and displayed two brightness peaks. A bright dot — about the size of Europa when seen in transit — marked the site of impact at latitude 51° north...

    Early science results from NASA’s Juno mission to Jupiter portray the largest planet in our solar system as a complex, gigantic, turbulent world, with Earth-sized polar cyclones, plunging storm systems that travel deep into the heart of the gas giant, and a mammoth, lumpy magnetic field that may indicate it was generated closer to the planet’s surface than previously thought. “We are excited to share these early discoveries, which help us better understand what makes Jupiter so fascinating,” said Diane Brown, Juno program executive at NASA Headquarters in Washington. "It was a long trip to get to Jupiter, but these...

    Our current theories regarding the formation of the Solar System claim that the planets formed about 4.5 billion years ago from a Solar Nebula (i.e. Nebular Hypothesis). Consistent with this theory, Jupiter is believed to have formed as a result of gravity pulling swirling clouds of gas and dust together. Jupiter acquired most of its mass from material left over from the formation of the Sun, and ended up with more than twice the combined mass of the other planets. In fact, it has been conjectured that it Jupiter had accumulated more mass, it would have become a second star....

    his giant world, which harbors nearly three times as much mass as all the other planets put together, attains opposition tonight (April 7), forming a straight line with Earth and the sun. Opposition also marks the point in a planet's orbit when it's closest to Earth; indeed, Jupiter is currently just 415 million miles (670 million kilometers) from Earth. Interestingly, for the first time in a dozen years, opposition comes when Jupiter is just past aphelion (the farthest point from the sun during planet's orbit, where Jupiter was on Feb. 16). This is therefore one of the most distant oppositions...

    NASA made the decision to leave the Juno spacecraft, currently orbiting Jupiter, in its current orbit that cycles around the gas giant every 53 days. The choice hinges on worries surrounding Juno's main engine, which displayed some out-of-the-ordinary readings as the team was preparing to shorten the probe's orbit. “Juno is healthy, its science instruments are fully operational, and the data and images we’ve received are nothing short of amazing,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate in Washington. “The decision to forego the burn is the right thing to do – preserving a valuable asset so...

    The NASA-employed Science Definition Team has been crafting a plan to launch a mission that would search for alien life on Jupiter's icy moon Europa. The extraterrestrial world of Europa is considered as among the most likely places in the solar system to have the ability to support life as we know it. Scientists have gathered evidence that the salty ocean that lurks beneath the icy crust of the moon could be hospitable to life. Recent models also hint that the icy world can produce oxygen and hydrogen, which suggests it may have the necessary energy to support life.

    Cher probably won’t be voting for Donald Trump in 2016. The billionaire host of “The Celebrity Apprentice” announced his presidential bid on Tuesday, and the pop icon was not happy about it. In a series of Tweets, Cher took Trump to task, declaring him a “Loudmouth Asshole, Who’s terrified of Windy Days.” “Donald Trump Can’t come up with a hairstyle that looks human,how can he come up with a plan to defeat ISIS,” she wrote in a reply to another user. Despite her assertion that the only state Trump would win in an election would be “The State of Desperation,”...

    Mods, this is such a vanity! Please move or remove as you see fit, if necessary. Could use some moving to Florida advice. Retiring in a few years from the DC, Maryland area. Have looked at Ocala because of the cool 55+ communities there, but the crime rate is scary. Also looking at Lake Mary and surrounding area. Costs are a lot less than in Maryland, and I admit to being a pathetic Disney junky. Advice, Floridians?

    NASA's Juno Jupiter probe won't be settling into its final orbit around the giant planet this week after all. Juno was scheduled to fire its main engine for the final time during the probe's close Jupiter flyby on Wednesday (Oct. 19), in a maneuver that would reduce the time it takes the spacecraft to circle the gas giant from 53 Earth days down to 14 days. But the mission team decided to postpone the burn in order to investigate an issue with valves that are part of Juno's fuel-pressurization system, NASA officials said. "Telemetry indicates that two helium check valves...

    Astronomers using NASA's Hubble Space Telescope have imaged what may be water vapor plumes erupting off the surface of Jupiter's moon Europa. This finding bolsters other Hubble observations suggesting the icy moon erupts with high altitude water vapor plumes. The observation increases the possibility that missions to Europa may be able to sample Europa’s ocean without having to drill through miles of ice. “Europa’s ocean is considered to be one of the most promising places that could potentially harbor life in the solar system,” said Geoff Yoder, acting associate administrator for NASA’s Science Mission Directorate in Washington. “These plumes, if...

    NASA has called a press conference on Monday when the space agency will announce a breakthrough on the planet Europa. The US group sent out a cryptic message, stating that there is “surprising activity” on Europa – the most well known of Jupiter’s 67 moons. NASA has been analysing data from its Hubble Space Telescope which is currently prowling the universe. The space experts said in a statement announcing the event on Monday, to be broadcast live at 7PM UK time: “Astronomers will present results from a unique Europa observing campaign that resulted in surprising evidence of activity that may...

    Tonight (Aug. 27), look toward the western horizon to see a rare celestial event and a parade of planets — no telescope required. Just above the horizon, Venus and Jupiter will appear so close to each other that, from some locations, the two planets will almost seem to touch. The next time Venus and Jupiter will get this close will be in November 2065. In addition to keeping a look out for this planetary conjunction, look higher up in the sky to see three other planets on parade: Saturn, Mercury and Mars.

    The San Diego-made camera aboard the Juno spacecraft survived in good working order when the satellite went into orbit around the gas giant on July 4th. NASA on Tuesday released the first image taken by "JunoCam" since the satellite began its primary mission of studying Jupiter's physical and chemical composition. The two megapixel camera developed by Malin Space Science Systems was turned off for operational reasons shortly before Juno entered orbit. But NASA switched the camera back on on July 10th and took a low resolution image that shows half of Jupiter and three of its moons, Io, Europa and...

    As Juno nears Jupiter tonight, the giant planet's powerful gravity will accelerate the spacecraft to an estimated top speed of about 165,000 mph (265,000 km/h) relative to Earth, mission team members said. "I don't think we've had any human[-made] object that's moved that fast, that's left the Earth," Juno principal investigator Scott Bolton, of the Southwest Research Institute in San Antonio, said during a news conference last week. The all-time speed record is currently held by NASA's Helios 1 and Helios 2 spacecraft, which launched in the mid-1970s to study the sun. Both probes reached top speeds of about 157,000...

    Having a great July 4th? The day gives us another cause to celebrate, as the Earth reaches aphelion today, or our farthest point to our host star. Aphelion is the opposite of the closest point of the year, known as perihelion. Note that the ‘helion’ part only applies to things in solar orbit, perigee/apogee for orbit ’round the Earth, apolune/perilune for orbit around the Moon, and so on. You’ll hear the words apijove and perijove bandied about this week a bit, as NASA’s Juno spacecraft enters orbit around Jupiter tonight. And there are crazier and even more obscure counterparts out...
