DAYTIME METEORS: The annual Arietid meteor shower peaks this week on June 7th and 8th. It's a strong shower, but the meteors are difficult to see because the sun is up when the shower is most intense. The Arietids are a rare daytime meteor shower. [more]

VENUS RETURNS: Have you noticed, lately, a bright pinpoint of light beaming through the rosy glow of sunset? That's Venus, returning to the evening sky after an absence of more than a year.

You can see Venus any evening this month. Wednesday, June 8th, is an especially good evening to look. The slender crescent Moon will be gliding by Venus. The pair are so bright, they pop into view even before the sky grows completely dark. [sky map]

Above: Can you find Venus in this picture? It's the light seemingly fixed atop one of the boat's masts. "This may be the only way for such a bright object to go unremarked," says photographer Laurent Laveder of Île-Tudy, Bretagne, France. "I do love this bright light in the twilight."

SOLAR ACTIVITY: The sun is a busy place today. Our star is peppered with 'spots, criss-crossed by dark filaments, and the limb of the sun is alive with arcing prominences. All of these things appear in the June 6th photo, below, from Gary Palmer of Los Angeles.

Despite all this activity, the chance of a strong solar flare remains low. None of today's sunspots have the sort of tangled, unstable magnetic fields that tend to explode.



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 are on a collision course with our planet, although astronomers are finding new ones all the time.

On 7 Jun 2005 there were 696 known Potentially
