A full moon sinking behind San Gorgonio Mountain, California, on a midsummer morning. Moonrise and moonset are times when the upper limb of the Moon appears above the horizon and disappears below it, respectively. The exact times depend on the lunar phase and declination, as well as the observer's location.
The crescent moon will appear to align with Venus and nearby Jupiter shortly after sunset on Feb. 23, an alignment that will be visible from the heart of bustling cities to the dark sky parks ...
This map, based on a survey of 300 TLPs by Barbara M. Middlehurst and Patrick Moore, shows the approximate distribution of observed events. Red-hued events are in red; the remainder are in yellow. A transient lunar phenomenon (TLP) or lunar transient phenomenon (LTP) is a short-lived change in light, color or appearance on the surface of the Moon.
The Moon is Earth's only natural satellite. It orbits at an average distance of 384,400 km (238,900 mi), about 30 times the diameter of Earth. Tidal forces between Earth and the Moon have synchronized the Moon's orbital period (lunar month) with its rotation period at 29.5 Earth days, causing the same side of the Moon to always face Earth.
The strongest geomagnetic storm in nearly 20 years began slamming into Earth on Friday, and as nightfall approaches in Idaho, there’s a good chance the Gem State’s sky could be alight with the ...
The Worm Moon will mark 2024’s first lunar eclipse. Thomas reveals lunar eclipses "are three times more intense, emotional and powerful." Thomas reveals lunar eclipses "are three times more ...
The Moon's maximum and minimum declination vary because the plane of the Moon's orbit around Earth is inclined by about 5.14° with respect to the ecliptic plane, and the spatial direction of the Moon's orbital inclination gradually changes over an 18.6-year cycle, alternately adding to or subtracting from the 23.5° tilt of Earth's axis.
"The Aristarchus plateau is one of the most geologically diverse places on the moon: a mysterious raised flat plateau, a giant rille carved by enormous outpourings of lava, fields of explosive volcanic ash, and all surrounded by massive flood basalts," said Mark Robinson, principal investigator of the Lunar Reconnaissance Orbiter Camera at ...
