Not exact matches

Uncertain krypton measures from earlier probes presented two possibilities: Venusian levels could match Earth's, indicating the two planets probably formed from similar ingredients in the primordial nebula, or they could differ enough to force scientists to toss out their theories on Venus's origins.

Studies of hydrogen molecules in the Venusian atmosphere by NASA's Pioneer - Venus probe indicate that the planet once had liquid water on its surface, perhaps even expansive oceans.

Suzanne Smrekar of the Jet Propulsion Laboratory and her colleagues deduced that lava flows on the flanks of several Venusian volcanoes appear unweathered, meaning that the flows must be no more than 2.5 million years old.

Prospects for Venusian life have been dismissed because of harsh conditions on the planet's surface: there is no water, temperatures reach 477 °C and the atmospheric pressure is 92 times that on Earth's surface.

To create such a feature, lava would have to remain fluid over great distances, prompting geologists to suggest that Venusian volcanoes discharge carbonatite lava, just like that one oddball volcano on Earth, Ol Doinyo Lengai.

In the July 25 issue of SN: A special report on time, Kennewick Man's ancestry, sex - change lizards, Venusian volcanism, Earth's missing craters and more.

One of the Venusian surprises discovered at that time is that radio waves are reflected differently at different elevations on Venus.

The first sighting of the light spectacle on another planet reveals properties of the mysterious Venusian clouds

Venus» composition is largely unknown because of a lack of Venusian meteorites found on Earth, and that mystery won't be unlocked anytime soon: No missions to Venus are planned.

The simulated image at left shows how the smaller particle size in Venusian cloud tops (compared to a typical 10 to 40 micrometers in terrestrial ones) causes the colored fringes to spread further apart than they would appear on Earth.

The hope is that this year's Venusian transit will provide a benchmark for further efforts to uncover the properties of these distant worlds (see «Transit of a lifetime: Why all eyes are on Venus now «-RRB-.

[Response: Yes, the Venusian atmosphere is a headache on many fronts.

Rocks interact with the Venusian atmosphere differently than they would with the surface atmosphere on Earth or Mars.

Kargel's estimate should be considered to be a lower limit on when the planet dried up because it did not include the effect of clouds in the Venusian atmosphere.

You can create and customize a male or female character based on one of three classes (Fighter, Engineer, Outcast), as well as one of three races (Human, Mercurian or Venusian).

Instead, the developers behind Incredipede and Pineapple Smash Crew have collaborated on one of the most bizarre and intriguing game concepts you'll see this year: an alien jellyfish procreation simulator set beneath the thick Venusian clouds, which challenges us to help an intrepid Cnidarian spread its seed and fertilise a variety of extraterrestrial flora.

If they mean a real transition to Venusian conditions, that is ridiculous, but if they only mean to imply that there are some amplifying feedbacks, then there is no argument (except on the terminology)-- but the issue is whether they will be large or small.

There was never runaway warming on Venus, and a bit more attention to the evidence, as Harry Huffman has done, shows the Venusian CO2 = warming is simply bad science.

He was an astronomer on the Pioneer Venus project before he joined NASA GISS but he shows a total ignorance of Venusian geology.

SummaryFor two years beginning in 2013, a large team led by Sanjay Limaye set out to combine and compare the following: Venusian atmospheric data collected by probes in the 1970s and 1980s (used to create the Venus International Reference Atmosphere, or VIRA) Venus Express data on the vertical and horizontal structure of the atmosphereEarth - based observations of the upper atmosphere temperature structure of Venus made since VIRAFigure 1a: Vertical coverage of post-VIRA atmospheric structure experi....

Hansen is wrong both about the possibility on earth and in Venusian past history.

It goes on to assert that any point in the Venusian atmosphere at the same pressure as the Earth's would be at the same temperature with appropriate adjustment for the relative power received from the sun.

You simply say that you don't believe the greenhouse effect can be responsible for Venusian temperatures and move on — despite the fact that some very, very fine scientific minds thought quite differently, and had the math to prove it.

(And of course, both Carl Sagan and James Hansen cut their scientific teeth on studies of the Venusian atmosphere.)

Sagan had proposed very high Venusian surface temperatures, and ascribed them to an ultra-strong greenhouse effect on the basis of careful calculations using all that was then known.

This same relationship seems to hold all throughout the Venusian atmosphere, so when you go to OTHER altitudes on Venus where the pressures are the same as on Earth, you see temperature differences in the same ratio, 1.176 (within a reasonable margin of error).
