    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...

    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...

    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...

    Fusion power is the technology that is 30 years away, and always will be, according to skeptics, at least. Despite its difficult transition into a reliable power source, the nuclear reactions that power the sun have a wide variety of uses in other fields. The concept fusion drive, called a direct fusion drive (or DFD), is in development at the Princeton Plasma Physics Laboratory (PPPL). Though still under development, the engine itself exploits many of the advantages of aneutronic fusion, most notably an extremely high power-to-weight ratio. The fuel for a DFD drive can vary slightly in mass and contains...

    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...

    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...

    APOD.NASA ^ | 5 Jul, 2020 | NASA/Cassini Imaging Team
    Explanation: Why would clouds form a hexagon on Saturn? Nobody is sure. Originally discovered during the Voyager flybys of Saturn in the 1980s, nobody has ever seen anything like it anywhere else in the Solar System. Acquiring its first sunlit views of far northern Saturn in late 2012, the Cassini spacecraft's wide-angle camera recorded this stunning, false-color image of the ringed planet's north pole. The composite of near-infrared image data results in red hues for low clouds and green for high ones, giving the Saturnian cloudscape a vivid appearance. This and similar images show the stability of the hexagon even...

    As the weekend comes to a close, the night sky will have one more treat for stargazers as Jupiter, Saturn and the moon rise together to form a triangle on Sunday night. The astronomical meetup will take place one night after the full ‘Buck Moon Eclipse,' but the moon will still appear nearly full as it rises with the two planets on Sunday night. "On Sunday night into Monday morning, July 5 to 6, 2020, the full Moon and the planets Jupiter and Saturn will form a triangle," NASA said. "The Moon will reach its highest [point] in the sky...

    Saturn's rings, Titan and the much smaller moon Enceladus. (NASA/JPL/Space Science Institute) ===================================================================== On human timescales, things in the Solar System seem to be pretty set in place. Over cosmic timescales, it's all gradually falling apart. The planets are very, very slowly moving away from the Sun; and most of the moons are slowly moving away from their planets in a process called tidal acceleration. The fact that Titan is slowly moving away from its planet - Saturn - is therefore not at all unusual. But astronomers have found something really surprising: Titan's outward migration is faster than expected -...

    Not long after NASA's Cassini mission arrived at Saturn in 2004, researchers realized that the planet's rings were oscillating strangely. Instead of single waves, which are predicted by existing theory, the spacecraft revealed clusters of small waves that could be explained by the presence of gravity waves in the deepest part of the planet's interior. On rocky planets like Earth, disturbances beneath the planet's surface can move as a wave, traveling through the planet's interior and through its surface.... Eventually, interference from other traveling waves can create a standing wave pattern spanning the entire planet. The same process occurs on...

    Explanation: What are those dots between Saturn's rings? Our Earth and Moon. Just over three years ago, because the Sun was temporarily blocked by the body of Saturn, the robotic Cassini spacecraft was able to look toward the inner Solar System. There, it spotted our Earth and Moon -- just pin-pricks of light lying about 1.4 billion kilometers distant. Toward the right of the featured image is Saturn's A ring, with the broad Encke Gap on the far right and the narrower Keeler Gap toward the center. On the far left is Saturn's continually changing F Ring. From this perspective,...

    BGR ^ | 06/26/2020
    As NASA reports in a new post, researchers recently discovered that Voyager 2 cruised through a blob of charged gas called a plasmoid as it passed the planet. The spacecraft’s journey through the plasmoid lasted only about a minute, but that was still long enough for scientists to spot the anomaly in the decades-old data. The scientists believe that gas loss may have already drained as much 55% of the planet’s atmosphere. Loss of atmosphere resulting in plasmoids has been observed around other planets in our solar system, including Saturn and Jupiter, though it’s thought that Uranus has leaked far...

    Early Tuesday morning, the waning crescent moon will be visible with the four planets down and to the left. As the sky begins to brighten, Mercury will rise and both Saturn and Mars will begin to fade from view. Both the Moon and Jupiter will remain visible as it gets lighter. By Wednesday morning, the moon will be closest to Jupiter and Mars. Jupiter is currently the brightest morning planet and it will be easy to pick out. Mars will be much dimmer in comparison. The moon will continue to get thinner as the week goes on. On Thursday morning,...
