New Satellites of Jupiter Discovered
dss902 writes "The discovery of 18 new satellites of Jupiter, bringing the total of known Jupiter satellites to 58 were made using the world's two largest digital cameras at the Subaru (8.3 meter diameter) and Canada-France-Hawaii (3.6 meter diameter) telescopes atop Mauna Kea in Hawaii. Recoveries were performed at the University of Hawaii 2.2 meter with help from Yanga Fernandez and Henry Hsieh also from the University of Hawaii. Brian Marsden of the Harvard-Smithsonian Center for Astrophysics performed the orbit fitting for the new satellites.

We ran a story on the
first eight,
but now... eighteen.
Some new worlds to explore with my starship made from a floppy!

... that all this time Jupiter has been mooning us 58 times simultaneously. That cheeky devil!

I don't know if the telescope is associated with the company. However, in Japanese, "Subaru" is the name for the the Pleiades star cluster.

In the proportion 1:3:9?
You mean the Canada-Freedom-Hawaii!! Silly Americans! Tricks are for kids!
Get your own Jupiter moon NOW! We offer to name any newly discovered satellite of Jupiter with a word of your choice. Rates starting at just $100/moon! For satellites up to a diameter of 500 km we charge only $100, and $50 extra for every 200km of additional size. You can pre-book a name for yet to be discovered satellites up to 3 years in advance! We have exclusive contracts with international astrophysical society. So hurry!!
The dept line says "jupiter's-a-daddy"..
Who is the mommy? Mother Earth of course! Why not Venus? Although hot, she's deadly.
The only problem is that Earth has things that can be transferred from planet to planet.. humans! A cosmic STD if you will.
When modding "Informative", please make sure it both has a source and IS actually informative.
What's the difference between a moon and a lump of rock? Why catalog rocks at Jupiter and let all the rocks in Saturn's rings go uncatalogued? Where is the dividing line?
Infuriate left and right
Yes, they make a telescope, and it transfers power from the moons that slip to the moons that grip!
In Soviet Rush, today's Tom Sawyer gets high on you.
What is a moon? We don't even have a definition for a planet yet.
Cloaking device? "That's no moon..."
One line blog. I hear that they're called Twitters now.
Please explain the logic that lead to your conclusion that these moons are so close to Jupiter? Smaller has NEVER meant closer to the primary. Mars is smaller than Earth. Saturn, Uranus and Neptune are smaller than Jupiter. Kuiper-Belt and Oort Cloud comets are smaller than nearly anything else. I could go on with this listing for quite a while, but you get the point.
If you check the database, all of these newly discovered moons are outside of the orbits of most of the heretofore known moons. Well, well outside, in fact. These irregular moons are probably captured asteroids.
For your calculation to be right, by the way, the moons would be orbiting Jupiter 35 meters from it's barycenter. I'm going to question your orbital semi-major axes. (Also, your mass of Jupiter is incorrect. It's 318 times the mass of Earth.) Also, moons don't rotate about their planet, they revolve. Rotate means to spin.
to think that given the size of the universe we are still discovering things that are practically on top of us. Makes you wonder what else is out there.
Do not try to read the dupe, thats impossible. Instead, only try to realize the truth
What truth?
There is no dupe
I always use Jupiter's satellites to name my servers and I was getting out of options.
I think someone should mod the parent poster up. Even if this is a serious attempt to criticize linux, it's more funny then a troll. I guess it is sort of off topic though.
Many of Jupiter's moons have distant orbits.
Thebe, Amalthea, Metis and Adrastea are small and close in, then Io, Europa, Ganymede, Callisto. The rest of them are in a mess of orbits going out quite a way.
Well, it's only appropriate that Jupiter have such a harem of consorts. Any idea what they'll be named?

It says satellites, not moons, big difference. It was my understanding that jupiter, along with all of the gas giants, each had inumerable satellites, they're called rings.

And they tend to stick to mythology names... Last October 11 Jupiter moons discovered 2-3 years earlier were assigned names from the Greco-Roman mythology.
If scientists want to find 100 moons orbiting Jupiter, there are going to be many Slashdot articles on new Jovian moons. Thus, I propose we create a new icon for all of these articles.
You know how it is with those crash diets. First you cut back until you're only 254 times as massive as the Earth. Then, you get a sudden craving for a frozen treat and have a couple of comets and bam! You're up to 318 again.
Galileo discovered only four but this (among other reasons) was enough for Roman Church to prosecute him. The existence of objects moving arround Jupiter was a serious problem for the official geocentric model of the universe, and therefore, a challenge to the authority of the Church. Only recently, the Pope apologized for that.
I wonder what would they think of the existence of 58 Jovian satellites, just to mention one of the wonders that science has discovered.. Can we reach conclusions from the past history and apply them to the present ?
Actually its owned by the Japanese goverment. As I recall, the prime contractor was Mitsubishi. That was a long time ago (10+ years) though, so I might be wrong. Big ass piece of glass though. 30+ tons, shipping box weighed another 30 tons.

Little background on the scope

so, everything smaller than us doesn't worth existing?
The article says that the orbits they'v calculated are only preliminary. I wonder if, when other gravitational fields are taken into acount, they're really closed around Jupiter. The satellites are orbiting backward, which sounds a lot like they used to orbit the sun forwards a little clsoer iun than Jupiter.
I wouldn't be surprised if they become sun-orbiting asteroids within 100 years.

So, you are better then them? What are you doing here on /. then? Why aren't you at the observatory providing us with better figures than they did?
...how long it will take for these moons to appear in Celestia.
Quaoar and 2002 MN were added only a few days after being discovered.

Why would Mitsubishi make a telescope named after a rival, Subaru? That seems like a bonehead move.

Ah, the sweet smell of prejudice. First off, I wouldn't think that I'd meet your definition of "hippie-slacker" all too well (whatever that might be). If by hippie-slacker you mean "CS student with a basic understanding of physics that shaves regularly and is just a little sceptical about governments going gung-ho", then yes, that's about me.
Second, I'd like to know what rights an asteroid has in your whacky little - and certainly interesting in case of a hit - world. That's a problem a lot of people would certainly love to see answered. I can imagine a dialogue going like this:
Fight hunger. Filet a politician and send him to a 3rd world country of your choice.
In addition, the logo you see on all Subaru cars is a set of stars - a stylized version of the constellation itself.
