Although Venus is a terrestrial planet similar to Earth, its atmospheric circulation is much different and poorly characterized1. Winds at the cloud top have been measured predominantly on the dayside. Prominent poleward drifts have been observed with dayside cloud tracking and interpreted to be cause...
The planet Venus is covered by thick clouds of sulfuric acid that move westwards because the entire upper atmosphere rotates much faster than the planet itself. At the cloud tops, about 65 km in altitude, small-scale features are predominantly carried by the background wind at speeds of ...
Studies of how stars evolve suggest that the early Sun was only about 70 percent as luminous as it is now, so the temperature in Venus’ early atmosphere must have been quite a bit lower. Thus water vapor would have been able to liquefy and form oceans on Venus. But if water vapor ...
The observant and adaptable young turtle introduces us to the next aspect of the Crescent phase: the waxing sextile, which occurs when the transiting Moon goes sixty degrees ahead of the Sun. Like the semi-square, the sextile is a predominantly mental aspect, but it carries a greater awarene...
Venus is sometimes referred to as Earth’s evil twin on account of it being almost the same size but plagued with a thick noxious atmosphere and a sweltering 470ºC (880ºF) surface. Its high pressure and temperature is hot enough to melt lead – and destroy the spacecraft that dare...
By contrast, Venus is very dry and its thick atmosphere is mostly carbon dioxide. The original atmospheres of both Venus and Earth were derived at least in part from gases spewed forth, or outgassed, by volcanoes. The gases that emanate from present-day volcanoes on Earth, such as Mount ...
is, enough of the liquid water on Venus would have vaporized to create a thick cover of water vapor clouds.Since water vapor is a greenhouse gas, this humid atmosphere—perhaps denser than Earth’s present-day atmosphere, but far less dense than the atmosphere that envelops Venus today—...
This work reviews possible signatures and potential detectability of present-day volcanically emitted material in the atmosphere of Venus. We first discuss
This is where the atmosphere is thickest and the light pollution is strongest, therefore giving you potentially bad data. Fun fact: deep space objects are actually HUGE! They are just too dim to actually see with the naked eye which is why we use cameras to photograph them. You may be ...
The highlands of Venus are characterized by an altitude-dependent change in radar backscatter and microwave emissivity, likely produced by surface-atmosphere weathering reactions. We analyzed Magellan and Arecibo data for these regions to study the roughness of the surface, lower radar-backscatter areas...
