What's up in Space

BLUE MOON: This Thursday evening, the Moon over North America will become full for the second time in the month of May. According to folklore, that makes it a Blue Moon. But will it really be blue? Believe it or not, blue-colored Moons are possible. Get the full story from Science@NASA.

A DAY AT THE BEACH: New sunspot 958 is not very large but it has a marvelous white beach. Pete Lawrence sends this picture from his backyard in Selsey, UK:

Astronomers call the phenomenon plage--French for beach. Plage is not sand but a bright, hot magnetic froth that surrounds many sunspots. It shows up particularly clearly in solar telescopes tuned to the purple glow of ionized calcium. Lawrence used a Calcium-K Personal Solar Telescope to obtain the photo above.

FIND THE MOON: On May 23rd, when photographer Guillaume Bertrand looked at the sky over Saint Laurent sur Sèvre, France, he was transported thousands of light years away. "The scene reminded me of a star-forming region in the Small Magellanic Cloud," he says. (continued below)

Photo details: Canon 300D

But when he took the picture and examined it closely, he found no stars--only the Moon! "Can you find it?" he asks. Click here to search.

When you locate the Moon, note how its surface brightness compares favorably to that of bright white clouds. That's why, contrary to popular belief, the Moon is so easy to see during the day.

Near-Earth Asteroids
Potentially Hazardous Asteroids (PHAs) are space rocks larger than approximately 100m that can come closer to Earth than 0.05 AU. None of the known PHAs is on a collision course with our planet, although astronomers are finding new ones all the time.
On May 30, 2007 there were 863 potentially hazardous asteroids.

Notes: LD means "Lunar Distance." 1 LD = 384,401 km, the distance between Earth and the Moon. 1 LD also equals 0.00256 AU. MAG is the visual magnitude of the asteroid on the date of closest approach.
