(Best Syndication) Astronomers say that most of the universe is made up of dark matter, which acts like a glue that holds the galaxies together. On Tuesday NASA scientists revealed an image of a “ghostly ring” taken by the Hubble Space Telescope. The ring is apparently composed of dark matter.

The NASA astronomers got their first-hand view of how dark matter behaves during a titanic collision between two galaxy clusters. The ghostly ring is similar to the ripple effect caused by dropping a rock into a pool of water. The ring can be seen in the “blue map” of the cluster’s dark matter distribution, which is superimposed on an image of the cluster.

Yahoo and Google Personalized Homepage Comparison – Google Has Done It Again With More Features and No Advertisements

Personal Google Home Page

(Best Syndication) Which personalized home page is better: Yahoo or Google? Although Google is relatively new to the personalized home page game, their home page is far easier to create with many more options. Also, the Google home page does not inundate you with advertising like Yahoo.

Both companies offer news, sports and entertainment, but Google offers a larger selection of sources. Yahoo is signed up with the big ones like Reuters, Associated Press and now some news papers; however Google News has over 4,500 news sources and is more likely to offer your local newspaper.

Yahoo is now offering a customizable calendar. The company is playing catch-up because Google has offered the customizable calendar with more features for some time now. The Google Calendar can also be embedded in forums and websites with simple HTML tags. We use the Google calendar on a few of our websites, and with one update we can modify all the calendars at once. Google also offers multiple calendars.

Amazon to compete with iTunes by selling MP3 Music Online with no Copy Protection

[Best Syndication] Amazon is going to expand their downloading of files for instant access to your favorite music. The good news is that they do not intend to have a complicated copy protection system.

Amazon.com will be competing against Apple’s iTunes, and Microsoft’s Zune music download sites.

The problem with copy protected music can be extremely frustrating. Sometimes the special program key could be lost when a computer system gets replaced. You could even have everything installed correctly and it still can glitch on you. If you invested in iPod technology and change out to a Zune you will find that the Zune isn’t able to play songs that you purchased on iTunes. If you buy songs from Napster or RealNetworks you can play them on an iPod. So you see how frustrating this can become when you want to change to a different MP3 music player.

NASA scientists believe that greenhouse gases will cause summer temperatures in the eastern United States to increase by nearly 10 degrees Fahrenheit by 2080.

Think about this, the study predicts temperatures to be between 100 -110 degrees Fahrenheit in Chicago, Washington, and Atlanta during the peak summer months of July and August by 2080.

"There is the potential for extremely hot summertime temperatures in the future, especially during summers with less-than-average frequent rainfall," said lead author Barry Lynn of NASA's Goddard Institute for Space Studies and Columbia University, New York.
