This Month's Stargazing Tips - from


Orion, Taurus, and Auriga, constellations that rep- resent autumn and winter, vanish in the western evening twilight this month. Hercules is well up in the east-northeast by then, with Ophiuchus just climbing into view in the east. Pairs of planets bracket the sky for much of the month: Jupiter and Saturn before dawn, and Venus and Mercury just after sunset.

May 9: Evening Mercury

The planet Mercury is in the early evening sky now. It looks like a bright star quite low in the west-northwest during twilight, well above brighter Venus. It will remain in view for most of the month.

May 10: Meeting the Milky Way

Although it is the combined light of millions of stars, the Milky Way is so faint that almost any artificial light source blocks the view. To see the Milky Way, get away from city lights, then look low in the east after midnight.

May 11: New Moon

The Moon is “new” today, as it crosses the imaginary line between Earth and Sun. It is lost in the Sun’s glare but will return to view as a thin crescent quite low in the west early Saturday evening.

May 12: Moon and Venus

The Moon and Venus, which is just beginning its reign as the Evening Star, stand side by side, quite low in the western sky, shortly after sunset. Venus will remain low in the sky for months before finally pulling into better view.

May 13: Moon and Mercury

Mercury is putting in one of its best appearances of the entire year. The little planet is low in the west-northwest as evening twilight fades. It looks like a fairly bright star. Tonight, it’s quite close to the crescent Moon.

May 14: Hercules

The constellation Hercules is in good view by the time it gets dark and soars high overhead during the night. Look for the Keystone — four stars that form a lopsided square. It’s in the northeast as darkness falls.

May 15: Farthest Stars

Virgo is well up in the southeast at nightfall, marked by its brightest star, Spica. The constellation contains the most distant star in our own galaxy yet seen, a million light-years from Earth. It is much too faint to see without a telescope.
