Note that the meridional circulation is much lower than the zonal circulation, which transports heat between the day and night sides of the planet. All winds on Venus are ultimately driven by convection. [3] Hot air rises in the equatorial zone, where solar heating is concentrated and flows to the poles.
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 ...
The visible cloud tops of Jupiter and Saturn provides further evidence on its deep atmospheric circulation demonstrating the presence of atmospheric super-rotation. [8] Jupiter's auroras, in particular, highlight the planet's rapid atmospheric movements through their ethereal glow and varying cloud depths.
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 stream, which starts at 6.30pm GMT on Thursday, is titled ‘The Kiss between Venus and Jupiter’. It is one of several night sky events noted by Nasa for March, which include a full Moon on ...
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 dense greenhouse atmosphere on Venus keeps its surface hot enough to melt lead throughout the night. [33] [34] Its planetary wind system, driven by solar heat, reverses direction from day to night. Venus's winds flow from the equator to the poles on the day side and from the poles to the equator on the night side.
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 ...
