i jedna slicica aurore na saturnu:

A marketing?:)

Sta moze da se radi sa zavrsenom vishom astronomskom skolom?Ako takva uopste i postoji?

Od cega su sastavljeni prstenovi na saturnu i sta ih odrzava da budu tu?

[Guest]

dark matter, teleskopi od 64 metra, 21 centimetar talasne dužine... kako mi pojma nemamo, to je bruka :)

jel ono na saturnu polarna svetlost, kao ona koja se vidi na zemlji, ili nešto drugo?

[Dule_smor]

Kolio ja znam kod nas ne postoji visa astronomska...a sa faxom i ne mozes nesto mnogo da radis, znaces brdo matematike i zavrsiti kao neki profa:)...dok je astrofizika malo bolje resenje...u svakom slucaju u ovo zemlji nema leba od toga...a prstenovi, pa cestice prasine, komadici leda i taj krs...a drzi ih naravno saturnova gravitacija

a shta je ono plavo na sredini planete?

outdoor zenba za astronaute.

[Dule_smor]

aaaa, pa to plavo je aurora(polarna svetlost), i nije na sredini vec na polu...omg:))...mada bazen zvuci zanimljivo:)

uu reve ja bih mu sada iskopao ip i kaznio ga.

U cekaj, naleteo sam ja na neku dobru fotku ... just a sec ...

A large, bright and complex convective storm that appeared in Saturn's southern hemisphere in mid-September 2004 was the key in solving a long-standing mystery about the ringed planet.

Saturn's atmosphere and its rings are shown here in a false color composite made from Cassini images taken in near infrared light through filters that sense different amounts of methane gas. Portions of the atmosphere with a large abundance of methane above the clouds are red, indicating clouds that are deep in the atmosphere. Grey indicates high clouds, and brown indicates clouds at intermediate altitudes. The rings are bright blue because there is no methane gas between the ring particles and the camera.

The complex feature with arms and secondary extensions just above and to the right of center is called the Dragon Storm. It lies in a region of the southern hemisphere referred to as "storm alley" by imaging scientists because of the high level of storm activity observed there by Cassini in the last year.

The Dragon Storm was a powerful source of radio emissions during July and September of 2004. The radio waves from the storm resemble the short bursts of static generated by lightning on Earth. Cassini detected the bursts only when the storm was rising over the horizon on the night side of the planet as seen from the spacecraft; the bursts stopped when the storm moved into sunlight. This on/off pattern repeated for many Saturn rotations over a period of several weeks, and it was the clock-like repeatability that indicated the storm and the radio bursts are related. Scientists have concluded that the Dragon Storm is a giant thunderstorm whose precipitation generates electricity as it does on Earth. The storm may be deriving its energy from Saturn's deep atmosphere.
