Clementine's camera reveals (from right to left) the Moon lit by earthshine, the Sun's glare rising over the Moon's dark limb, and the planets Saturn, Mars, and Mercury (the three dots at lower left). Planetshine is the dim illumination, by sunlight reflected from a planet, of all or part of the otherwise dark side of any moon orbiting the body.
Astronomers have been tracking the so-called Halloween comet, also known as C/2024 S1, since it was discovered in September by a telescope in Hawaii. Rare comet visible in the night sky won’t ...
Earthlight is the diffuse reflection of sunlight reflected from Earth's surface and clouds. Earthshine (an example of planetshine ), also known as the Moon's ashen glow , is the dim illumination of the otherwise unilluminated portion of the Moon by this indirect sunlight.
Paranal Observatory nights. [3] The concept of noctcaelador tackles the aesthetic perception of the night sky. [4]Depending on local sky cloud cover, pollution, humidity, and light pollution levels, the stars visible to the unaided naked eye appear as hundreds, thousands or tens of thousands of white pinpoints of light in an otherwise near black sky together with some faint nebulae or clouds ...
Satellite flare, also known as satellite glint, is a satellite pass visible to the naked eye as a brief, bright "flare".It is caused by the reflection toward the Earth below of sunlight incident on satellite surfaces such as solar panels and antennas (e.g., synthetic aperture radar).
Planetshine – Illumination by reflected sunlight from a planet Earthshine – Light reflected from the Earth; Zodiacal light – Faint solar glow caused by interplanetary dust at sunset and sunrise; Gegenschein – Optical effect of interplanetary dust reflections
Zodiacal light is produced by sunlight reflecting off dust particles in the Solar System known as cosmic dust. Consequently, its spectrum is the same as the solar spectrum. The material producing the zodiacal light is located in a lens-shaped volume of space centered on the sun and extending well out beyond the orbit of Earth.
Lunar nearside with major maria and craters labeled Earthshine reflecting off the Moon. The bright region at left is directly illuminated by sunlight, while the rest of the Moon is faintly lit by sunlight reflected off the Earth. Generally, the Moon can be viewed even with the naked eye, however it may be more enjoyable with optical instruments.
