Weizmann scientists help unveil the depths of Jupiter's winds

Juno is now scheduled to remain in orbit around Jupiter until July 2018, but NASA is looking at ways to extend the mission.
The Weizmann Institute of Science in Rehovot, Israel, is one of the world's top-ranking multidisciplinary research institutions. Each of the 15 storms appear to persist independently without merging for reasons that remain unknown.
Among the scientific mysteries uncovered are weird geometric constellations of cyclones on both of Jupiter's poles. Those eight circumpolar cycles that surround the larger central cyclone on the planet's north pole are 2,500 to 2,900 miles in diameter.
At Jupiter's north and south poles, the cyclones are so densely packed that they actually touch one another.
They also say the massive cyclones on the planet's north and south poles are unique - nothing in the solar system can compare to them. "Our results imply that the outer differentially-rotating region should be at least three times deeper in Saturn and shallower in massive giant planets and brown dwarf stars".
The researchers said that in future orbits they plan on using similar gravitational studies to investigate the depth and structure of Jupiter's iconic spot. At the south pole, it was the same arrangement, only with five storms. Thought to be as old as the planet itself, these bands are sculpted by high-speed winds whipping around the orb in opposite directions, and constitute the "face" Jupiter presents to the outside world.
The study is published across four separate articles in the journal nature (1,2,3 and 4), covering the planets asymmetrical gravitational field, polar cyclones, atmospheric flows and interior makeup. "This was certainly a surprise". We've spent so long only being able to see the striped glory of the very top layer of its atmosphere that it's hard to think Juno and its suite of instruments won't learn something we never even imagined. 2018. Jupiter's atmospheric jet streams extend thousands of kilometres deep.
"As of recently, we just had a shallow comprehension of them and have possessed the capacity to relate these stripes to cloud includes along Jupiter's planes".
Guillot and his colleagues say the gravitational asymmetry is the result of complex atmospheric and interior wind flows. Among the measurements Juno beamed back to Earth are those of the planet's gravity field, sent via radio waves: As the planet's gravity pulls on the spacecraft in its flyby, the radio signal is also shifted a bit; this shift in the wavelengths, though minuscule, is measurable.
That's one of the biggest mysteries about Jupiter right now: We aren't sure if the planet is gas and liquid through and through or if there's something solid buried deep within it. Gravity measurements collected by Juno during its close flybys of the planet have now provided an answer.
In the first paper, researchers led by Luciano Iess of the Sapienza University of Rome in Italy used Doppler data to study Jupiter's gravitational field. Using the radio link between Juno and the Earth, the team was able to measure the velocity of the probe down to changes of one-hundredth of a millimeter.
According to prisoners rights group Addameer, there were 6,119 Palestinian prisoners being held in Israeli custody as of February. The clashes followed a weekly demonstration against the recent USA decision to recognize Jerusalem as Israel's capital.
Union Home Minister Rajnath Singh and Bharatiya Janata Party (BJP) president Amit Shah will attend the ceremony. The independent candidate Tongpang Ozukum and JD (U)'s G Kaito Aye were also inducted into the new cabinet.
On the other hand, JD (U) also promised the support of its lone MLA to the alliance, despite a previous alliance with NPF. The BJP leaders informed the governor that Y Patton had been elected the BJP Legislature Party leader in the Assembly.
As far as screen size goes, the Note 9 may well match the 6.3 inches of the Note 8 , just a shade bigger than the S9 Plus. The Note has been said to apply an under-display sensor which is something Samsung wasn't' able to do on the S9.
That amount of snow would shred the record for snowfall in Philadelphia on this date - 4 inches in 1969. Breezy, with a west southwest wind 8 to 16 miles per hour , with gusts as high as 23 miles per hour .
Jordan, being the nice guy that he is, felt a little bad about the whole thing and offered a helping hand. Jordan later tweeted out a public response to her in which he offered to replace her retainer.
Alabama lawmakers have proposed multiple measures in response to last month's killings of 17 people at a Florida high school. School official confirmed the shooting did not come from "someone from the outside came into the school", according to ABC .
The constantly changing "weather" in space makes it hard to predict when the space station would crash-land on Earth. It is expected that Tiangong-1's re-entry will be longer (and more dazzling) due to its greater size.
The French CAC 40 rose by 0.22% lifted by utilities, the Italian FTSE MIB 100 climbed by 0.17% and the UK's FTSE 100 was flat. Silver was down 0.2% at $16.47/oz, while platinum fell 0.4% to $948.70/oz after touching its lowest since January 4 at $943.

Unlike the last Senate election in 2015, lawmakers were prohibited from taking their phones into the assemblies during the vote. Nearly all political parties have expressed dismay at the elections laws of Senate and promised to improve them.
