A moon at the new phase comes most nearly – for any particular month – to passing between the Earth and sun. Next new moon is March 28, 2017 at 02:57 UTC. For time zones in the Americas, that’s the evening of March 27; translate to your time zone.

Modern techniques – telescopes, filters, photography – have made it possible to see the moon even at the instant it becomes. That’s the case with Thierry Legault’s image, above, which he acquired in 2013. Read more about the image here.

But – for most of us, on the day of new moon – unless we’re viewing an eclipse of the sun, we won’t see the new moon. That’s because a new moon rises when the sun rises. It sets when the sun sets. It crosses the sky with the sun during the day.

A new moon is too close to the sun’s glare to be visible with the eye.

The next solar eclipse will be total and visible from North America. It’ll be the first total solar eclipse visible from contiguous North America since 1979. Read more about the August 21, 2017 total solar eclipse. Composite image of a 2006 solar eclipse by Fred Espenak.

It’s only as the moon moves in orbit, as its lighted hemisphere begins to come into view from Earth, that we can see it in our sky. Then we see the moon in the west after sunset as a slim waxing crescent – what some call a young moon.

That typically happens a day or two after new moon, but – with the March 2017 new moon – if you’re in North America, you might spot the moon on March 28, the day your calendar says it’s new. There are a couple of reasons for this, which you can read about here.

On March 28, and for a couple of nights after that, the very young, very slim crescent moon will be moving up past the planets Mercury and Mars in the western twilight sky.

Watch for it!
