Similarly, Joel Kowsky, the astronomer of NASA recorded the lunar occultation of Venus the same day from Washington, D.C. The lunar occultation of Venus on this date was the second lunar occultation of the Venus in the same year. [13] 2020 Venus was eclipsed by the Moon at 19 June 2020 from 9:44:15 - 10:46:12 PM (UTC+2). [14] [15] 2021
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 ...
At V band, the emission from airglow is V = 22 per square arc-second at a high-altitude observatory on a moonless night; in excellent seeing conditions, the image of a star will be about 0.7 arc-second across with an area of 0.4 square arc-second, and so the emission from airglow over the area of the image corresponds to about V = 23.
Venus, Mars, Jupiter and Saturn will line up in the sky this week and could stay visible to the naked eye for a number of weeks. ... The Moon will also join the line-up on April 23, with a fifth ...
The reason for this is that when Venus is closest to Earth, it is between the Earth and the Sun, so only its night side is seen. Even when Venus is brightest in the Earth's sky, humans see only a narrow crescent. For a Mercurian observer, on the other hand, Venus is closest when it is in opposition to the Sun
It would be a very large object in the night sky, shining about 8% [nb 3] as bright as the Moon (it would appear darker than the Moon because its lesser illumination comes from a larger disc). Charon's illuminance would be about 14 mlx (for comparison, a moonless clear night sky is 2 mlx while a full Moon is between 300 and 50 mlx).
