Quiz[edit | edit source]


1 Yes or No, Spring has finally come to the northern hemisphere of Uranus.


2 True or False, The aurorae of the planet Uranus are in line with its equatorial rings.


3 Complete the text:

Match up the type of Sun system astrogony with each of the possibilities below:
Babylonian epic story of creation - A
a primordial or first Greek god - B
the primeval chaos - C
creation of heaven and earth - D
Greek god personifying the sky - E
Cronus (Saturn) castrating his father - F
separation of the waters by a firmament

Chaos magno


watery abyss


Enuma Elish


4 Yes or No, A 1998 false-colour near-infrared image of Uranus show cloud bands, rings, and moons obtained by the Hubble Space Telescope's Near Infrared Camera and Multi-Object Spectrometer (NICMOS) camera.


5 True or False, According to Hesiod's Theogony, Uranus was conceived by Gaia alone, but other sources cite Aether as his father.


6 There is anecdotal evidence that people had seen the Galilean moons of Jupiter before telescopes were invented. Of similar magnitude, Uranus and

had most probably been seen but could not be recognized as wanderers because they appear so faint even at maximum brightness that their motion could not be detected.

7 Yes or No, As a demonstration of ALMA's new short wavelength capabilities, the commissioning team released a new image of planet Uranus as it appears in submillimetre wavelength light.


8 True or False, The discovery of Uranus' non-dipolar, non-axisymmetric magnetic field destroyed the picture-established by Earth, Jupiter and Saturn-that planetary magnetic fields are dominated by axial dipoles.


9 Which phenomena are associated with the dynamo of Uranus?

axisymmetric magnetic field
sulfur volcanoes
water oceans
bipolar magnetotail
detached bow shock
obtuse rotation

10 Yes or No, In January 1986, the Voyager 2 spacecraft flew by Uranus at a minimal distance of 107,100 km providing the first close-up images and spectra of its atmosphere. They generally confirmed that the atmosphere was made of mainly hydrogen and helium with around 2% methane.


Hypotheses[edit | edit source]

  1. Uranus is a remainder of a once large solar system that was intruded upon by the Sun.
