June new moon 2021: See a ‘ring of fire’ solar eclipse as the moon goes dark

The new moon occurs Thursday (June 10) at 6:52 a.m. EDT (1052 GMT), and it brings with it a solar eclipse at least partially visible over a large part of the Northern Hemisphere. Two days later the moon makes a close pass to Venus, while an active meteor shower graces the predawn skies. 

Solar eclipses occur when the moon is directly between the Earth and sun, at the new moon. Technically, a new moon means the sun and moon share the same celestial longitude, a projection of the Earth’s longitude lines onto the sky. This position is also known as a conjunction. Usually the new moon passes near, but not in front of, the sun because its orbital plane isn’t perfectly lined up with that of Earth; it’s about five degrees off. Sometimes, though, the two line up, and the result is a solar eclipse.
