    The Juno spacecraft orbiting Jupiter has discovered an FM radio signal coming from the moon Ganymede. The find is a first-time detection from the moon. Patrick Wiggins, one of NASA’s Ambassadors to Utah, says, “It’s not E.T. It’s more of a natural function.” Juno was traveling across the polar region of Jupiter, where magnetic field lines connect to Ganymede, and that’s when it crossed the radio source. Scientifically, it is called a “decametric radio emission.” Here on earth we know it as Wi-Fi. And we use it every day. According to, Jupiter’s radio emissions were discovered in 1955, and...
  • Rare Mercury, Jupiter, and Saturn ‘triple conjunction’ to light up sky this weekend

    From Jan. 9-12, Mercury, Jupiter, and Saturn will be visible in the southwestern sky. The celestial event is known as a “triple conjunction,” which means two planets and a third planet meet each other in the sky for a short period of time. Shortly after sunset on Jan. 9, look above the west-southwestern horizon and you will see Mercury to the left of Saturn and Jupiter positioned just above Saturn. “From Friday evening to Monday evening, the planet Mercury will appear to pass first by Saturn and then by Jupiter as it shifts away from the horizon, visible each evening...

    Today's image is a video at link. Explanation: Yes, but have you seen a movie of Jupiter and Saturn's Great Conjunction? The featured time-lapse video was composed from a series of images taken from Thailand and shows the two giant planets as they angularly passed about a tenth of a degree from each other. The first Great Conjunction sequence shows a relative close up over five days with moons and cloud bands easily visible, followed by a second video sequence, zoomed out, over 9 days. Even though Jupiter and Saturn appeared to pass unusually close together on the sky on...

    Explanation: It was time for their close-up. Two days ago Jupiter and Saturn passed a tenth of a degree from each other in what is known a Great Conjunction. Although the two planets pass each other on the sky every 20 years, this was the closest pass in nearly four centuries. Taken early in day of the Great Conjunction, the featured multiple-exposure combination captures not only both giant planets in a single frame, but also Jupiter's four largest moons (left to right) Callisto, Ganymede, Io, and Europa -- and Saturn's largest moon Titan. If you look very closely, the clear...

    THE GREAT CONJUNCTION OF JUPITER AND SATURN: Want to see something that astronomers have been waiting 800 years to witness? Just step outside at sunset and look southwest. Jupiter and Saturn are having their finest conjunction since the Middle Ages--and they're bright. Bertrand Kulik sends this picture from Paris:"On Dec. 20th, the planets were visible right beside the Eiffel Tower," says Kulik. "It was a magical view!" At closest approach on Dec. 21st, the two planets will lie just 0.1 degrees apart. That’s so close, some people will perceive them as a single brilliant star. Viewed through binoculars or a...

    The first image below is pretty much the situation in the night sky now, Nov 25, 2020. Little by little, Jupiter, from our perspective, is inching closer and closer to Saturn. And by mid-December the two planets will appear to be practically on top of each other, I think both within the space of a full moon! The 2nd image below is the situation in mid-December (this is NOT a one-day, or even one week, thing).In fact the two planets are fairly close to each other right now, Nov 25 (first image below).But in reality, Saturn is actually something like...

    Explanation: Why do colorful cloud bands encircle Jupiter? Jupiter's top atmospheric layer is divided into light zones and dark belts that go all the way around the giant planet. It is high horizontal winds -- in excess of 300 kilometers per hour -- that cause the zones to spread out planet-wide. What causes these strong winds remains a topic of research. Replenished by upwelling gas, zonal bands are thought to include relatively opaque clouds of ammonia and water that block light from lower and darker atmospheric levels. One light-colored zone is shown in great detail in the featured vista taken...

    Just after sunset on the evening of December 21, 2020, Jupiter and Saturn will appear closer together in Earth’s night sky than they have been since the Middle Ages, offering people the world over a celestial treat to ring in the winter solstice. Jupiter and Saturn have been approaching one another in Earth’s sky since the summer. From December 16-25, the two will be separated by less than the diameter of a full moon. Though the best viewing conditions will be near the equator, the event will be observable anywhere on Earth, weather-permitting. Hartigan said the planetary duo will appear...
  • Europa glows: Radiation does a bright number on Jupiter's moon

    This illustration of Jupiter's moon Europa shows how the icy surface may glow on its nightside, the side facing away from the Sun. Variations in the glow and the color of the glow itself could reveal information about the composition of ice on Europa's surface. Credit: NASA/JPL-Caltech ======================================================================= As the icy, ocean-filled moon Europa orbits Jupiter, it withstands a relentless pummeling of radiation. Jupiter zaps Europa's surface night and day with electrons and other particles, bathing it in high-energy radiation. But as these particles pound the moon's surface, they may also be doing something otherworldly: making Europa glow in the...

    Mercury will likely be the hardest planet to spot, and binoculars would help. First, look for Venus. Venus is still the brightest of the planets and the third brightest celestial object, only behind the sun and the moon. Venus will be easy to find in the east before and during dawn. Once you’ve located Venus, look beneath it toward the horizon. Mercury will be low in the east-southeast about an hour before sunrise. Mars, Jupiter and Saturn will be visible in the evening. Mars is getting less bright by the day, but it will still be easy to find in...

    Explanation: Saturn and Jupiter are getting closer. Every night that you go out and check for the next two months, these two bright planets will be even closer together on the sky. Finally, in mid-December, a Great Conjunction will occur -- when the two planets will appear only 0.1 degrees apart -- just one fifth the angular diameter of the full Moon. And this isn't just any Great Conjunction -- Saturn (left) and Jupiter (right) haven't been this close since 1623, and won't be nearly this close again until 2080. This celestial event is quite easy to see -- already...

    JACINTA BOWLER 5 OCTOBER 2020 Mars, our second closest cosmic cousin, has been in our collective imagination for decades. Between fantasies of martian visits and the promise of water under its icy surface, Mars doesn't need to do much to be in our collective good books. But very soon, Mars is not just going to be close to our hearts, but also nearest to our actual planet - a mere 62.1 million kilometres (38.6 million miles) away from Earth. This is the closest it'll be for the next 15 years. And it means that stargazing is highly recommended as Mars...

    Its frozen shell is encrusted with a layer of white and orange ice. The endless twisting and pulling of Jupiter’s gravity leaves a surface crisscrossed by deep valleys, ridges, and not yet fully understood “chaos zones” of deep tectonic activity. Its immense dark oceans, heated by underwater volcanoes, are hidden by this icy surface — that is, except for when it explodes outwards in titanic geysers, shooting plumes of liquid water hundreds of miles into space.No, this isn’t science fiction — this is Europa, the hauntingly beautiful yet bizarre ocean moon of Jupiter. Scientists have called Europa “the most...

    Set your alarm for two hours before sunrise to catch the best view of Jupiter sinking in the southwestern sky with Saturn just above and to the right, according to Travel and Leisure magazine. Trace a curved line through both planets into the southern sky and you'll hit Mars high above the southeastern horizon. To see Venus and Mercury, trace Mars' curve down to the horizon in the northeast. Before you get there, you'll easily spot Venus, one of the brightest objects in the night sky. Also, be sure to pencil in a special date between these five planets. Just...
