Tonight (Tuesday, 5/22) if you're fortunate to have an unobstructed view of the western sky, you might see the tiniest sliver of new moon hanging close to Venus and much fainter Elnath, second brightest star in the constellation Taurus.

This will be the final pass the Moon makes by Venus before she disappears from the evening sky.  All spring she has dazzled us with her radiance, culminating with the startingly lovely conjunction with Jupiter in mid-March that brightened the western sky for hours after sunset.  Once Venus disappears below the horizon, she will trace a particularly historic path between Earth and the Sun – one that will cast a visible silhouette over the Sun's glowing disk.  Then, by the end of June, she will step back onto the starry night's stage, this time cast as the glorious 'Morning Star,' joining her pal Jupiter to herald the dawns of mid-summer.

Check back here in the next few days for more musings on Venus's transit of the Sun, and tonight appreciate the waxing crescent moon's goodbye kiss to our celestial sister.  The next time the two meet will be when the moon is waning to new in mid-July.  One annular solar eclipse down; one transit of Venus and a partial lunar eclipse to go.
