What’s in March’s night sky? Here are the highlights:

  • Venus, the “Evening Star,” is returning to the skies, after a year’s absence! Each evening, 30 minutes after sunset, it’s ever so slightly higher up. Get more details about Venus here.
  • Mercury has its best evening star showing of the year. To the right of returning Venus, it begins rather low in evening twilight but gets higher and brighter and looks best from the 5th to the 18th, still to the right of Venus.
  • March March 18 on your calendar. Venus is strikingly joined by the thin crescent Moon. Look 35 minutes after sunset and an amazing line up will float just above the spot where the Sun set. From left to right the thin crescent moon, Venus, and the elusive planet Mercury, a don’t miss apparition.
  • Jupiter rises at midnight, with the Moon nearby on the night of the 6th to 7th. In the predawn scene, the Moon hovers between Mars and Saturn on the 10th. Those two planets meet on the last two mornings of the month.
  • Spring begins with the equinox on the 20th, at 12:15 P.M. ET.  Here’s more information about Spring Equinox 2018.

The Moon

March is a special month, not only because it’s when the spring equinox occurs, but also because it will host two full Moons this year—one on the 1st and another on the 31st. See the March 2018 Moon Guide.

a visible planet in the night sky

I have recently been seeing during the night a very bright planet (or star...) somewhat near the moon. It doesn't seem to be the time when I should be seeing either Venus or Jupiter and there doesn't seem to be a constellation where I'm seeing the bright star or planet. Do you know what this is? Thank you.
