Because the impact basins were often the lowest places on the Moon’s surface, they would begin to fill with erupting lava. These dark areas formed when massive asteroid or meteorite impacts on the Moon’s surface created basins. ![]() In the Moon’s youth, its interior was still molten, and magma would erupt onto its surface. These gray patches are solidified volcanic lava flows. ![]() Looking at the Moon with only your eyes, you see mostly areas of white and gray. The shadows on the surface will be more pronounced, and help distinguish features you might otherwise miss. ![]() You can look at the Moon during any of its illuminated phases, but for better viewing of craters and mountains, try phases other than the full Moon. During its crescent phase in the twilight or dawn, you can also sometimes see the dark portion of the Moon glowing faintly in the sunlight that reflects off Earth, an effect called earthshine. The Moon has no glow of its own, but shines with the reflected light of the Sun.

I’m an expert on eclipses-the editor of and author of The Complete Guide To The Great North American Eclipse of Ap. Check planet-rise/planet-set, sunrise/sunset and moonrise/moonset times for where you are. For the most accurate location-specific information consult online planetariums like Stellarium and The Sky Live. Times and dates given apply to mid-northern latitudes. Everywhere else in North America will see a partial solar eclipse. That’s what happens on October, 14, 2023 during which the moon will cover just over 90% of the Sun’s disk-though only seen from a path from Oregon through Texas. However, if the New Moon is at apogee (farthest from the Earth) and thus smaller in the sky it black only the central part of the sun’s disk in an annular (ring) solar eclipse. During this eclipse season a New Moon at perigee (closest to Earth on its elliptical orbit) can block out 100% of the Sun’s disk and cause a total solar eclipse.

Solar eclipse glasses will be necessary for everyone everywhere. ![]() Everywhere else in the Americas, save for Alaska and the southern tips of Argentina and Chile, will see a partial solar eclipse. However, that weird sight will only be visible from a 125 miles wide path through nine U.S. Since it’s a little farther from Earth than on average on its elliptical path it cover only 91% of the sun’s center to create a “ring of fire.” September’s New Moon does something special today when it fits perfectly in front of the sun to cause a solar eclipse.
