Ashen light is a hypothesised subtle glow that has been claimed to be seen on the night side of the planet Venus.The phenomenon has not been scientifically confirmed, and theories as to the observed phenomenon's cause are numerous, such as emission of light by Venus, or optical phenomena within the observing telescope itself.
On rare occasions, Venus can actually be seen in both the morning (before sunrise) and evening (after sunset) on the same day. This scenario arises when Venus is at its maximum separation from the ecliptic and concomitantly at inferior conjunction; then one hemisphere (Northern or Southern) will be able to see it at both times. These respective ...
Venus is a primary feature of the night sky, and so has been of remarkable importance in mythology, astrology and fiction throughout history and in different cultures. The eight-pointed star a symbol used in some cultures for Venus, and sometimes combined into a star and crescent arrangement.
The EnVision Venus explorer will study that planet in unprecedented detail, from inner core to the top of its atmosphere, to help astronomers understand why the hot, toxic world didn’t turn out ...
The Belt of Venus – also called Venus's Girdle, the antitwilight arch, or antitwilight [1] – is an atmospheric phenomenon visible shortly before sunrise or after sunset, during civil twilight. It is a pinkish glow that surrounds the observer, extending roughly 10–20° above the horizon .
This situation results in a decrease in visual sensitivity in central vision at night. Based on the early work of Osterberg (1935), and later confirmed by modern adaptive optics, [7] the density of the rod cells usually reaches a maximum around 20 degrees off the center of vision. Some researchers have contested the claim that averted vision is ...
Throughout December, Venus will move higher and higher in the night sky, setting several hours after the sun. Because of how bright Venus will appear, some are referring to it as this year's ...
The reason for this is that when Venus is closest to Earth, it is between the Earth and the Sun, so we see only its night side. Indeed, even when Venus is brightest in the Earth's sky, we are actually seeing only a narrow crescent. For a Mercurian observer, on the other hand, Venus is closest when it is in opposition to the Sun and is showing ...
