A fifth planet discovered in a distant solar system

November 07, 2007

Astronomers led by Debra Fischer of San Francisco State University in California and Geoff Marcy of the University of California in Berkeley have discovered a fifth planet in the 55 Cancri system, and it seems that it is now becoming possible to detect solar systems that look like our own. Most planets discovered outside our own solar system so far were generally very huge and hot, but 55 Cancri now looks like a Sun-like system with a larger number of planets.

This discovery could also be interpreted as a proof that a solar system like ours is not that unusual, that Earth-like planets could likely exist in other solar systems too, and potentially even support life. The newly discovered planet is located inside the so-called habitable zone, even if it has a mass 45 times that of the Earth and is probably a gas planet that doesn't allow life at all. "We can only imagine that it might look something like a beefy Neptune-like planet or perhaps a Saturn-like planet with rings and moons around it," Fischer says, and she also suggests that "if there is a moon orbiting this new, massive planet, it might have pools of liquid water on a rocky surface.".

But it looks like 55 Cancri's habitable zone could contain more planets, even Earth-like and life-friendly ones, but todays technology is not yet capable of detecting such small objects at such a distance. 55 Cancri is about 41 lightyears away from our solar system, it is slightly cooler and dimmer than our own Sun. The newly detected planet orbits the star at a distance of 117 million kilometres.

7 Simple Steps to Create Your Own Solar System Online

November 03, 2007

Would you like to create your own online solar system with planets, moons and life forms and be part of a virtual galaxy? Well, if that's something you'd like to do, then Galaxiki is probably the place you're looking for. If you don't know Galaxiki yet, go ahead and take a look at our community site. So here's a short 10 step manual that will teach you how to get it done!

1. Go to the Galaxiki website (that's www.galaxiki.org) and create an accout if you don't have one yet (it's free, of course).

2. Explore the galaxy a bit so that you see how it works. There are stars with and without planets, double star systems, planets that allow life forms, neutron stars, black holes and so on.

3. Select a solar system you'd like to edit. As a site member you can edit solar systems owned by the community for free, or you may purchase your own system that only you will be able to edit.

Option a) If you'd like to edit a community system then you'll have to find one first. Check out your account page which lists some of them randomly, or go to the Community page sidebar and check out the "Recently freed community stars" or the "Solar systems donated by our users" for example. Simply click onto the solar system name to open it.

Option b) If you'd like to purchse your own system then you can chose whatever system you want, as long as it doesn't belong to someone else yet of course. Simply navigate through the galaxy until you find something you like, or go to the solar systems screen "Explore > popular solar systems" or "Community > popular solar systems" which lists a bunch of interesting and available systems, including double star systems and systems featuring planets that allow life forms for example. Once you purchased a solar system it will be listed on your account page so that it won't get lost...

4. Now that you selected a community solar system or purchased your own system, click onto the "edit" tab to name your star/system and your planets (you'll note that the entire editor logic is wiki based and pretty much Wikipedia-like). You're allowed to freely invent your star and planet names, but be careful not to use any trademarks, names from existing Sci-Fi novels or movies, or anything too silly.

5. After naming your star and planets you can edit them by clicking onto "edit star" or "edit planet". A text editor opens, this is where you can write the story of a planet and its life forms in your own words - quite cool for talented story writers, but don't panic if you're not a good writer, just put in a few lines, of leave it all empty if you want.

Tip: If you'd like to own or name solar systems but you're not a good writer, consider opening your solar system to the community. You can do this by clicking onto the first icon in the solar system list on your account page. Check out the legend for more info.

6. Finetune the dropdown options in the "Physics" and the "History, Habitability and Life" tabs (hint: information entered here will be used in future site search features, so it would be good to check them and to set them up correctly).

7. Click onto the "Images of..." Tab if you'd like to upload an drawing or rendering of your star, planet or solar system. That's an optional feature, but if you'd like to use it make sure not to use images that are copyrighted - in other words, upload your OWN drawings or renderings, not something you found somewhere on the web.

You're done!

If you finished all these steps then your solar system work should be completed now. It's already "published", so there's no need to take any further steps. But you may want to tell friends and other people about it now. Therefore each solar system has an ID as well as a permalink - here's an example for a link to RAF085, a double star system with 3 planets:

https://galaxiki.org/star/?RAF085

Use the permalink to send it to your friends, or to use it in your blog or on your website for example. If you own a website or a blog you can also place a solar system widget onto your site, which displays your star and planets as a 200 x 200 pixel image. Clicking onto the widget will lead visitors directly to your solar system.

NASA: New Lakes Discovered on Saturn's moon Titan

October 29, 2007

NASA Scientist Dr. Tony Phillips writes about the latest discoveries on Titan (or Saturn VI), which is "...the largest moon of Saturn, the only moon known to have a dense atmosphere, and the only object other than Earth for which clear evidence of stable bodies of surface liquid has been found." as Wikipedia tells us.

Newly assembled radar images from the Cassini spacecraft are giving researchers their best-ever view of hydrocarbon lakes and seas on the north pole of Saturn's moon Titan, while a new radar image reveals that Titan's south pole also has lakes.

About 14 percent of the mapped region is covered by what scientists believe are lakes filled with liquid methane and ethane. Lakes and seas are very common at Titan's high northern latitudes where winter is now underway. Scientists say it rains methane and ethane there, filling the lakes and seas.

Titan was discovered by Christiaan Huygens in 1655, it is the second-largest moon in the Solar System, after Jupiter's moon Ganymede.

Space: Hundreds of Black Holes Found

October 27, 2007

Posted by CowboyNeal on Slashdot:

"Hundreds of black holes that were thought to exist at the beginning of the universe have been found by NASA's Spitzer and Chandra space telescopes. From the article, 'The findings are also the first direct evidence that most, if not all, massive galaxies in the distant universe spent their youths building monstrous black holes at their cores. For decades, a large population of active black holes has been considered missing. These highly energetic structures belong to a class of black holes called quasars. A quasar consists of a doughnut-shaped cloud of gas and dust that surrounds and feeds a budding supermassive black hole. As the gas and dust are devoured by the black hole, they heat up and shoot out X-rays. Those X-rays can be detected as a general glow in space, but often the quasars themselves can't be seen directly because dust and gas blocks them from our view.' This is pretty big, as it's empirical evidence proving the existence of objects that theoretically had to exist but could not be detected previously."

The Dacor And Peoples Opinion

October 25, 2007

Has anyone seen the Dacor lately? They are surely making a name for themselves, aren't they? What I want to know, is what do you, my fellow galaxikians, think about the Dacor. Do you think the idea is goood? Should I develop it more? What could I do to improve.
