  • This May Be the Best Evidence Yet of a Water Plume on Jupiter's Moon Europa

    05/14/2018 10:23:16 AM PDT · by Simon Green · 16 replies
    Space.com ^ | 05/14/18 | Mike Wall,
    The case for a giant plume of water vapor wafting from Jupiter's potentially life-supporting moon Europa just got a lot stronger. NASA's Hubble Space Telescope has spotted tantalizing signs of such a plume multiple times over the past half decade, but those measurements were near the limits of the powerful instrument's sensitivity. Now, researchers report in a new study that NASA's Galileo Jupiter probe, which orbited the planet from 1995 to 2003, also detected a likely Europa plume, during a close flyby of the icy moon in 1997. The newly analyzed Galileo data provides "compelling independent evidence that there seems...
  • Jupiter and Venus Change Earth’s Orbit Every 405,000 Years

    Over the course of the past 200 million years, our planet has experienced four major geological periods (the Triassic, Jurassic and Cretaceous and Cenozoic) and one major ice age (the Pliocene-Quaternary glaciation), all of which had a drastic impact on plant and animal life, as well as effecting the course of species evolution. For decades, geologists have also understood that these changes are due in part to gradual shifts in the Earth’s orbit, which are caused by Venus and Jupiter, and repeat regularly every 405,000 years. But it was not until recently that a team of geologists and Earth scientists...

    That bright “star” is actually a planet, the king of them all as far as our Solar System is concerned: Jupiter. May also ushers in Jupiter observing season, as the planet reaches opposition on May 9th, rising in the east opposite to the setting Sun to the west. Jupiter now joins Venus in the dusk sky, ending the planetary drought plaguing many an evening star party. Shining a magnitude -2.5 near opposition, you can even pick Jupiter out against the deep blue daytime sky… if you know exactly where to look for it. The Moon visits Jupiter once every orbit,...

    The unnamed asteroid shares Jupiter's orbital space while moving in the opposite direction as the planet, which looks like a recipe for a collision, astronomers said. Yet somehow, the asteroid has managed to safely dodge Jupiter for at least tens of thousands of laps around the sun, a new study showed. It was given the provisional designation 2015 BZ509 with the nickname "BZ." Scientists noticed that the asteroid moves in the opposite direction of every planet and 99.99 percent of asteroids orbiting the sun, in a state known as retrograde motion. ... BZ may seem like a lucky asteroid, narrowly...

    Io boasts more than 130 active volcanoes with an estimated 400 total, making it the most volcanically active place in the Solar System. Juno used its Jovian Infrared Aurora Mapper (JIRAM) to take spectacular photographs of Io during Perijove 7 last July... Juno’s Io looks like it’s on fire. Because JIRAM sees in infrared, a form of light we sense as heat, it picked up the signatures of at least 60 hot spots on the little moon on both the sunlight side (right) and the shadowed half. Like all missions to the planets, Juno’s cameras take pictures in black and...

  • Juno Isn’t Exactly Where it’s Supposed To Be. The Flyby Anomaly is Back, But Why Does it Happen?

    universetoday.com ^ | 12/01/2017 | Matt Williams
    In the early 1960s, scientists developed the gravity-assist method, where a spacecraft would conduct a flyby of a major body in order to increase its speed. Many notable missions have used this technique, including the Pioneer, Voyager, Galileo, Cassini, and New Horizons missions. In the course of many of these flybys, scientists have noted an anomaly where the increase in the spacecraft’s speed did not accord with orbital models. This has come to be known as the “flyby anomaly”, which has endured despite decades of study and resisted all previous attempts at explanation. To address this, a team of researchers...

    Jupiter is a big, complex, chaotic planet. It has long been known as the most dominant feature in our sun’s orbit, but it wasn’t until last May that the planet’s internal features began to be revealed. During a few close passes, NASA’s $1.1 billion Juno spacecraft collected data on the gas giant that revealed cyclones the size of Earth and a surprisingly strong magnetic field. Now, data collected by Juno have uncovered more never-before-seen features on its north and south poles. In a study published this week in the journal Nature, a team of scientists report bizarre geometric storms surrounding...

  • Jupiter’s Great Red Spot may be dying, and could disappear within our lifetimes

    “In truth, the GRS has been shrinking for a long time,” Glenn Orton of NASA’s Jet Propulsion Laboratory told Business Insider. The storm was once as large as four times the diameter of Earth, but more recent observations have shown that it’s rapidly losing steam. “Now it’s something like 13 degrees wide in longitude and only 1.3 times the size of the Earth,” Orton says. “Nothing lasts forever.” Late last year, Juno revealed some surprising information about the huge storm, including how deep into the planet it goes. The data showed that the storm is up to 100 times deeper...

    Like Jupiter, Neptune has a giant spinning mystery. NASA's Hubble Telescope captured a time-lapse of the storm for the first time and found a surprising conclusion—it is shrinking. Officially called a "dark vortex," the Neptunian storm shares a few properties with Jupiter's Great Red Spot (GRS). Like the GRS, a dark vortex is moving in a anti-cyclonic direction that sweeps up material from the planet's icy atmosphere. “We have no evidence of how these vortices are formed or how fast they rotate,” said Agustín Sánchez-Lavega from the University of the Basque Country in Spain in a NASA press statement. “It...

    A stunning new Nasa image shows raging storms on Jupiter with clouds that stretch for thousands of miles - and it looks just like an oil painting. Nasa's Juno spacecraft was a little more than one Earth diameter from Jupiter - or 8,292 miles (13,345 kilometres) - when it captured this mind-bending view of the planet's tumultuous atmosphere. The incredible colour-enhanced image was captured at a latitude of 48.9 degrees and depicts vasts swirling cloud formations that travel at about 129,000 mph (60 km/s) over the gas giant planet's surface. The spacecraft, which has been orbiting the planet since 2016,...

    (Summarized from E. L. Martin, "The Star that Astonished the World," ASK Publications, Box 25000, Portland Or. 1991) (1) The date of the birth of Christ hinges on just one thing, the statement of Josephus (Antiquities 17.6-8) that Herod died shortly after an eclipse of the moon. Astronomers supply the dates for such eclipses around those years: None in 7 or 6 BC. In 5 BC, March 23, 29 days to Passover. Also in 5 BC. Sept. 15,7 months to Passover. In 4 B.C. March 13, 29 days to Passover. 3 and 2 B.C. no eclipses. In 1 BC. January...

    The Epistle ^ | Bruce Gerig
    The modern search for the Star of Bethlehem began with Johannes Kepler (imperial astronomer for Rudolph II of Germany), who shortly before Christmas in 1603 observed a conjunction (pairing) of Jupiter with Saturn from his observatory in Prague. That this occurred in the constellation of Pisces he thought was important as well – perhaps recalling Rabbi Isaac Abarvanel's belief, noted in his 15th-century commentary on Daniel, that not only does a conjunction of Jupiter and Saturn foretell important events, but in Pisces this holds a special significance for Israel; and such an event might even foretell the coming of the...

    For centuries, historians, scientists and scholars have debated the existence of the Star of Bethlehem in the Biblical telling of Christ’s birth. Now Texas lawyer and professor Rick Larson says he has proven the existence of this celebrated, yet debated, star. He sets forth his case in a documentary, “The Star of Bethlehem.” “Historically, people have taken two positions on the Star,” said Larson in a news release. “Either they believe the Star is true or they think it was made up by the early Church. I took a different approach in my research and treated the Star as a...

    According to a new study conducted by an international team of scientists, it may have something to do with a massive impact that occurred in the past. Since Venus appears to have never suffered such an impact, its never developed the dynamo needed to generate a magnetic field. ... According to the most widely-accepted models of planet formation, terrestrial planets are not formed in a single stage, but from a series of accretion events characterized by collisions with planetesimals and planetary embryos – most of which have cores of their own.

    Jupiter and Venus will pair up in the sky on Monday morning, shining brightly together shortly before sunrise. The two planets will appear so close together that they may look like they are just one bright star rather than two planets. This is the closest these two planets will appear all year, an astronomical event known as a conjunction. Venus and Jupiter may appear very close to each other in the morning sky, but they are actually more than 400 million miles away from each other. Venus and Jupiter will rise together about one hour before sunrise in the eastern...
  • Juno Finds that Jupiter’s Gravitational Field is “Askew”

    Jupiter’s gravity field varies with depth, which indicated that material is flowing as far down as 3,000 km (1,864 mi). Combined with information obtained during previous perijoves, this latest data suggests that Jupiter’s core is small and poorly defined. This flies in the face of previous models of Jupiter, which held that the outer layers are gaseous while the interior ones are made up of metallic hydrogen and a rocky core. ... Another interesting find was that Jupiter’s gravity field varies with depth, which indicated that material is flowing as far down as 3,000 km (1,864 mi). Combined with information...
