Today, the WorldWide Telescope has been made available to the general public. You may remember the WorldWide Telescope as the technology that made Scoble cry, but even without that hype, the project stands on its own as an amazing platform for scientific exploration and discovery. This virtual telescope is actually comprised of terabytes of imagery, collected and combined from the best ground and space-based telescopes in the world. Using Microsoft's Visual Experience Engine, you can use the telescope to pan and zoom through the night sky, moving in and around planets, stars, and even galaxies. Of course you can view the moon and the planets with WWT, but the imagery from this telescope also lets you do things you've never been able to before from your computer - like watching stars being born or galaxies collide.  

For both scientists and educators, the WorldWide Telescope will help to teach astronomy, computational science, and even provide opportunities for scientific discovery. For users of the telescope, there are rich media tours to that offer narration, music, text, and graphics to guide you through the night sky. It's like going to the planetarium without leaving your home! You can also make your own tours to share with others - a feature that teachers will really enjoy.

I've been playing with WWT tonight and it really is amazing to see the galaxies in their actual positions in the universe and be able to zoom and move them around on the screen. There are several different collections of images to explore - constellations, Hubble images, planets, and many more that I wasn't familiar with but were just as amazing. Click on one of the items from the collection zooms you right to the object in the sky. WWT is rich with technology that will appeal to astronomers, but it's still simple enough for the everyday user.

The telescope is based on technology that came out of Microsoft Research, an area of the company that has operated for 16 years which focuses on long-term, broad-based projects such as this. It's built on work that began with Jim Gray’s SkyServer and contributions to Sloan Digital Sky Survey.

A new article over at PCWorld.com offers up 22 tips on more efficient ways to perform common tech tasks - things like reinstalling Windows, backing up your data, creating a podcast, making a web site, sharing photos, and more. Here are a few sample tips from the article:

Add a Folder to Your Favorites: Drag the beloved folder from Windows Explorer to the Start button, and from there to the Favorites menu. In Windows XP, you also have the option of opening the folder and then clicking Favorites, Add to Favorites from inside the Explorer window.

Fix a Photo's Exposure: Microsoft's Windows Live Photo Gallery app improves on Vista's Photo Gallery program. Select Fix, Adjust Exposure In Windows Live Photo Gallery (which runs in both Vista and XP), and you'll get both Highlights and Shadows sliders and a histogram, as well as the familiar old Brightness and Contrast options.

Read the News: A number of free services can send you RSS feeds over e-mail. My favorite is SendMeRSS.com, which is so easy that you don't even have to register with the site, although doing so will make adding feeds simpler. Just enter the URL for the RSS feed you want, type in your e-mail address, and click Feed. From then on, new items will automatically appear in your inbox.

Email Large Files: My rule of thumb: Never e-mail more than 1MB of content without the express permission of the recipient. As an alternative, try YouSendIt, a brain-dead-simple take on the FTP transfer. The service is free for any file under 100MB, and individual files can be downloaded up to 100 times. You don't even have to sign up and enter a password (though the service offers additional features if you do, and even more if you pay). Just enter both e-mail addresses, point to the file, and click the Send button.

There are eighteen other great tips like those above, so you're sure to discover some tip, idea, or software app to use that you didn't already know about before.

Last week, the startup Xobni launched their public beta, so now everyone can get their hands on the Outlook plugin that turns your inbox into a social network. Xobni (that's "inbox" backwards!), taps into the hidden social network you spend time with every day: your inbox. The plugin runs in a sidebar where it analyzes and extracts info about you and your relationships.

During their private beta, they tweaked several things, fixed bugs, and even decided to streamline the plugin a bit by removing the "organize" tab, instead choosing to focus on their core product's offerings - super-fast search and relationship management. Using Xobni, you have access to features like threaded conversations, analytics, user profiles, a "related people" feature, shared attachments, and other automatically extracted info - like phone numbers for your contacts. To get in on the Xobni public beta, just visit the Xobni homepage and sign up.

Remember how I told you that you could add Wikipedia to your choices in Windows Vista's default search? Well, there are other ones you can add, too, like these:

Live Search: http://search.live.com/results.aspx?q=%+

IMDB: http://search.imdb.com/find?s=all&q=%+

Dictionary Search: http://dictionary.reference.com/search?r=2&q=%+

Now what I need to know is how I can use all of them - the gpedit.msc section (see earlier instructions on this) only lets you pick one. I want them all! Any ideas?
