It has been a superb winter for viewing the queen of the planets, Venus. February marks the pinnacle of its evening visibility as it stands like a sequined showgirl nearly halfway up in the western sky at sunset.
You can't miss it. Just look west after sunset. In fact, you can see it during the day if you know where to look. Find it just after sunset one evening, then scan around the same spot just before sunset the next day.
Currently shining at its greatest brilliance for this current apparition, this dazzling evening "star" currently appears as a distinct crescent shape in small telescopes, which is growing progressively larger in size as it approaches our Earth; its cloudy disk is now about one-fourth illuminated and shrinking nightly but right now its diminishing phase exactly offsets the gain in brightness from its growing apparent size. It is what astronomers call the "greatest illuminated extent" of this planet's disk.
On Friday night, Feb. 27, a lovely crescent moon will appear to snuggle up close to Venus, particularly for skywatchers across the Western Hemisphere. It will make for an eye-catching scene as the two brightest sky objects of the night dominate the early evening scene for about three hours after sundown; even those who do not normally look up will likely have their attention drawn to this "dynamic duo" during their normal commute home from work or school.
What will make this array especially attractive is the fact that it will look almost three-dimensional; the moon will look almost like an eerily illuminated blue and yellow Christmas ball hovering next to the brilliant-white diamond that is Venus.
Sadly, this will be the last in the current series of evening get-togethers between the moon and Venus, for during March Venus will slide rapidly down into the sunset glow and by month's end will disappear from our evening sky until the spring of 2010.
