If there was any doubt that the Earth was round, the famous Blue Marble photograph definitely put it to rest 35 years ago. After you’ve checked out the photo for yourself, read on for our earthly updates.

• Vista from the ground up: It’s just a pre-beta version now, but Yahoo! Messenger just got its full Vista-cred from the bottom up with new features like drag and drop tabs for your conversations, emoticons with a little extra oomph, options to change skin color for every IM window (for the color-conscious) , and sending files (fun photos or work documents) larger than 2G to friends and coworkers. That’s just the start, there’s much more we’re planning and testing, so try it out and tell us what you think. And stay tuned for the next release here.
• Take us on your trip: We’ve launched a new “My Travel” experience on Yahoo! Travel so you can keep track of all your trip plans, user reviews, photos and recent searches. You can also use this anthology to share your travel interests with other Yahoo! Travel users. There's even an interactive map that can be personalized with all the places you’ve been to and places you want to go. The best part? The Yahoo! FareChase will automatically monitor and pull up price drops for flights to your dream locations. Talk about reminding yourself to take a vacation! Start your profile page now so you can take us with you on your next journey!
