Nightly Events

  • Tonight:

    The brightest star in the sky, Sirius, sparkles due south at 7:45, and heads into the southwest later this evening, one of the first stars out as twilight fades. Its brilliance is due, in part to its relative closeness, only 8.6 light years away, as well as putting out about 25 times more light than our Sun.

  • March 20:

    The Vernal or Spring Equinox marks the calendar arrival of Spring just as the Sun is setting at 5:58 PM EDT, when the Sun is positioned directly above the Earth's equator. At this same moment, the Full "Worm" Moon is rising due east, and will spend 12 hours crossing the nighttime skies.

  • March 21:

    With the last of twilight gone near 8 o'clock, look to the east, where a nearly Full Moon climbs into skies, escorted by the brilliant pale-orange star Arcturus well to its left. Arcturus ranks second in brightness for the stars, in part because it is relatively nearby, at 37 light-years away.
