Due to the similarity in pressure and temperature and the fact that breathable air (21% oxygen, 78% nitrogen) is a lifting gas on Venus in the same way that helium is a lifting gas on Earth, the upper atmosphere has been proposed as a location for both exploration and colonization.
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 the place of the first interplanetary human presence, mediated through robotic missions, with the first successful landings on another planet and extraterrestrial body other than the Moon. Currently in orbit is Akatsuki, and other probes routinely use Venus for gravity assist manoeuvres capturing some data about Venus on the way. [253]
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 terraforming of Venus or the terraformation of Venus is the hypothetical process of engineering the global environment of the planet Venus in order to make it suitable for human habitation. [1] [2] [3] Adjustments to the existing environment of Venus to support human life would require at least three major changes to the planet's atmosphere ...
Compared to Mercury, the Moon and other such bodies, Venus has very few craters. In part, this is because Venus's dense atmosphere burns up smaller meteorites before they hit the surface. The Venera and Magellan data agree: there are very few impact craters with a diameter less than 30 kilometres (19 mi), and data from Magellan show an absence ...
A NASA spacecraft has captured never-before-seen images of Venus, providing stunning views of the hellishly hot surface of the second rock from the sun. Dark side of Venus revealed in new NASA ...
This heat is transferred to the gas in contact with the surface, both greenhouse, and non-greenhouse. Then the atmosphere is warmed by convection. This allows heat to be retained through the night, etc. Why Venus is so hot is one of the outstanding mysteries of science, so I obviously can't give you a fully satisfactory answer.
