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 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.
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. [15] [16] On rare occasions, Venus can actually be seen in both the morning (before sunrise) and evening (after sunset) on the same day.
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 European Space Agency has officially adopted two new space missions to study Venus from its atmosphere to inner core and to search for gravitational waves.
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 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 ...
This month’s stargazing agenda brims with planet sightings. We have planet pairings, moon-planet hangouts, and a special treat to end the month: several evenings with all seven of our space ...
