X-37B SIGHTINGS: Amateur satellite watchers have spotted a US Air Force space plane similar in appearance to NASA's space shuttle circling Earth in a heretofore secret orbit. Known as the "X-37B," it can be seen in the night sky shining about as brightly as the stars of the Big Dipper. Flyby predictions and more information may be found at http://spaceweather.com .

AURORA WATCH: A magnetic filament on the sun erupted yesterday (May 24th), and the blast hurled a coronal mass ejection in the general direction of Earth. High-latitude sky watchers should be alert for auroras around May 27th when the advancing cloud is likely to deal a glancing blow to our planet's magnetic field.

Atlantis and the ISS Transit the Sun
Space Weather News for May 23, 2010
http://spaceweather.com
SOLAR TRANSIT: Yesterday in Switzerland, Thierry Legault photographed the International Space Station and space shuttle Atlantis passing directly in front of the sun, not far from new sunspot 1072. The veteran astrophotographer calls the image his "best ever of a solar transit," and indeed the silhouette of the docked spaceships backlit by "solar fire" is a must see. It is featured on today's edition of http://spaceweather.com.
DOUBLE FLYBY ALERT: Atlantis is scheduled to undock from the ISS on Sunday, May 23rd, at 11:22 am EDT, setting the stage for double flybys over many towns and cities around the world. Need a flyby prediction? There's an app for that: http://simpleflybys.com .

Amazing 3D Space Station Movie
Space Weather News for May 14, 2010
http://spaceweather.com
Today's edition of spaceweather.com features a remarkable 3D movie of the International Space Station (ISS) recorded by French astrophotographer Thierry Legault. No special glasses are required to see the ISS pop out of your screen in amazing detail.
The movie will whet your appetite for a weekend of bright spaceships and planets. On Friday, May 14th at 2:20 pm EDT, space shuttle Atlantis is scheduled to launch from Kennedy Space Center on its final voyage to the ISS. An on-time liftoff would set the stage for an incredible sky show. On Saturday and Sunday, May 15th and 16th, many observers will be able to see Atlantis and the ISS flying past Venus and the crescent Moon in the evening sky. Visit http://spaceweather.com for sky maps and more information.
Seeing the ISS is easy if you know when to look. Sign up for Spaceweather PHONE (http://spaceweatherphone.com) and we will call you when the space station is about to fly over your hometown.

THE BIRDS AND THE TREES: As songbirds migrate across the United States each fall and spring, even tiny urban forests may offer a big boost to their chances for survival, according to a new study in the journal Landscape Ecology. Researchers used data from radio tags to learn the Swainson's thrush (pictured) often rests and refuels in small tree clusters while making its grueling cross-country trips, and they even deduced how the bird decides when to pull over. "We were able to record how long the birds were staying, and we found that it was not necessarily the forest size that was influencing the birds," one of the study's co-authors tells the BBC. "Instead, they were responding to internal factors, such as [the amount of] fat reserves they had." In other words, it's like a hungry family settling for fast food on a road trip instead of holding out for something better. But unlike McDonald's and Taco Bell, bird-friendly forests may be getting harder and harder to find, the authors write: "With the expansion of urban areas worldwide, migrating songbirds increasingly encounter fragmented landscapes where habitat patches are embedded in an urban matrix." Since land birds spend up to 90 percent of their migrations resting and regaining energy, the researchers say their study shows the importance of even minor tree-conservation efforts. "These findings suggest that remnant forests within urban areas have conservation value for Swainson's thrushes and, potentially, other migrant land birds," one says. "Obviously, larger forest patches are better, but even smaller ones are worth saving." (Source:
CAR TALK: Toyota has announced that it will purchase $50 million in stock of the electric car company Tesla during its initial public offering of stock later this year. The joint venture will operate out of the recently shuttered auto plant known as Nuumi in Freemont, Calif. Listeners of the popular This American Life radio show will be familiar with the Nummi plant, which revolutionized car assembly in the mid-1980s. (The radio show recently
