The Astronomy of Mother's Day
Science@NASA - 06 May 2010
Looking for a great Mother's Day gift? Your search is over.
Mom wants a wake up call.
At dawn on Sunday, May 9th--Mother's Day--the crescent Moon and Jupiter are getting together for a lovely conjunction. Only 5o of arc will separate the two bright celestial delights as they hang together in the sunrise-colored sky. Mom doesn't even have to go outside. A glance out any east facing window will frame the show quite nicely:

...
Only Mom can tell you if this is going too far at 5:30 in the morning.
In rare cases, Mom will not want to be woken up at the crack of doom--er, dawn. She might even refuse to get out of bed. If this happens, you'll need a backup plan.
Good news: There's also a nice display at sunset. Just as the sun is going down and the sky is fading to a deep cobalt blue, two bright lights will pop out of the twilight: Venus and Sirius. You can't miss them (especially Venus) shining halfway up the western sky:

...
Heavenly pearls and diamonds are a nice way to wrap up the day—especially if you misjudged that wake up call.
Happy Mother's Day!
