“Images taken by the Hubble Space Telescope in 2011 and 2012 revealed two previously unknown moons of Pluto. So far, we have been calling them “P4” and “P5”, but the time has come to give them permanent names. If it were up to you, what would you choose?” [x]
“The naming of a moon is a rare privilege for any astronomer. Fewer than 200 moons have been discovered orbiting the Solar System’s planets (dwarf or otherwise).
Over the centuries, the astronomical community has established standards for the naming of moons. Most names come from ancient mythologies. The moons of Uranus are the exception, with names coming primarily from the works of William Shakespeare.
These rules ensure that newly-discovered moons receive names that have already stood the test of time. The same names will still be in use centuries and even millennia from now. Whereas today’s literature might be long forgotten, we can be confident that future generations of astronomers (and maybe even astronauts) will still recall the stories from Mount Olympus and Stratford-upon-Avon.
I suspect these naming traditions did not arise by accident. For whatever reason, we humans seem to have a deep-seated, pre-scientific need to interpret the night sky in terms of stories. Naturally, we choose the big stories, involving grand themes, great powers and deep mysteries.
Starting today, we are trying something new. We are asking the public to help us name the moons. Visit plutorocks.seti.org and tell us what you think. We have seeded the ballot with a few names, or you can propose your own. The names will still have to be approved by the International Astronomical Union, but we will use your votes to help us decide the names we propose.”
Here raw footage from NASA’s Cassini and Voyager missions has been combined in a stunning portrait of Saturn and Jupiter. Watch as tiny moons create gravity waves in the rings of Saturn and observe the complicated relative motion between the cloud bands on Jupiter and the swirls and vortices that result. Fluid dynamics are truly everywhere. (Video credit: Sander van den Berg; submitted by Daniel B)
