Infrared image of the night-side of Venus, showing different layers of clouds at altitudes of 35 to 50 km in different colours. Red coloured clouds are the highest, green and blue are below. Carbon dioxide and monoxide areas are absorbing infrared signatures. Venusian clouds are thick and are composed mainly (75–96%) of sulfuric acid droplets ...
The planet's period of retrograde motion is 20 days on either side of the inferior conjunction. In fact, through a telescope Venus at greatest elongation appears less than half full due to Schröter's effect first noticed in 1793 and shown in 1996 as due to its thick atmosphere. Venus in daylight at 5 p.m. in the southern hemisphere ...
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 orbit of Venus is 224.7 Earth days (7.4 avg. Earth months [30.4 days]). The phases of Venus result from the planet's orbit around the Sun inside the Earth's orbit giving the telescopic observer a sequence of progressive lighting similar in appearance to the Moon's phases. It presents a full image when it is on the opposite side of the Sun.
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 ...
Earth's cosmic next-door neighbors will appear in the sky only a finger's width apart on July 12.
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.
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 ...
