EarthSky Tonight—September 8, High tide alert! Closest new moon of 2010

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Today – September 8 – features the closest new moon of 2010. Look for higher-than-usual tides along coastlines throughout the world. Because it crosses the sky with the sun during the day, you cannot see today’s extra-close new moon. Yet, it will usher in large tides along the ocean coastlines for the next several days, especially if these high tides are accompanied by strong onshore winds. 
Why is this moon so close? ... Full Story

EarthSky Tonight—September 5, Hazy pyramid of light in east? False dawn.

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Late summer and early autumn present the best time of year to see the false dawn, also known as the zodiacal light. With the moon out of the morning sky for the next two weeks, this is your chance to catch the zodiacal light before dawn. This light can be noticeable and easy to see from latitudes like those in the southern U.S. I’ve seen it many times from the latitude of southern Texas, sometimes while driving a lonely ...

EarthSky Tonight—September 1,  Venus, Mars, Spica meet in west after sunset early September

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org The first few evenings of September 2010 present a celestial trio – the planets Venus and Mars, and the star Spica fitting within a circle that is smaller than 5 degrees in diameter. Because a typical binocular field spans about 5 degrees of sky, there is a good chance of seeing all three luminaries squeezing up together inside a single binocular field. All three should be bright enough to see with the unaided eye, if your sky ... Full Story
