Volcano in Venus

  1. Jun 24, 2012 #1
    Peaks of mountains in Venus are more than that on the Earth
    Is there any active volcano?

    Plz tell me about any active volcano in space

    Google. I found the answer to your questions using google in less than 30 seconds (and so can you). Just make sure you're looking at reliable websites.

    thanks for googling it
    but anything can be there right or wrong
    somewhere i read there are no active volcano somewhere else there are volcanos.......
    which is correct?
    have u observed any volcanic activities on venus personally?

    I personally have not had the pleasure of witnessing a live volcano erupt on Venus.

    I think the fact that, when you google it, there are seemingly credible sources arguing both ways, you have come to the conclusion that "we don't know for sure". In terms of Venus, it is particularly hard to know because of the dense clouds that surround it. The best look at it that we have been able to get is an infrared shot from an ESA spacecraft.

    This article is your best bet for high quality information on this subject. You may have to make an account there to read it, but that will be for the best, because then you'll be a member of a wonderful place, and will have access to more information should you have questions in the future.

    Good luck! (I don't mean to be vague, but so long as you read through that article that I linked you to, and possibly read others that are similar to it from the same journal, then most of your questions should be answered).

    EDIT: Only the first section is applicable to Venus and the possibility of active volcanoes in that article that I linked you to. For more in depth explanations of it, just do a quick search on that website and there should be others. Most of them have issues with presenting copies of them, so I don't know how well that would go down if I went around and posted links of it all over the internet.

    http://volcano.oregonstate.edu/oldroot/volcanoes/planet_volcano/venus/intro.html has an article entitled: "Volcanoes on Venus", which begins as follows:

    "Volcanoes on Venus

    "Overview

    "Venus has more volcanoes than any other planet in the solar system. Over 1600 major volcanoes or volcanic features are known (see map), and there are many, many more smaller volcanoes. (No one has yet counted them all, but the total number may be over 100,000 or even over 1,000,000). These volcanoes come in a variety of forms. Most are either Large Shields or Smaller Shield volcanoes, but there are also many Complex Features, several Unusual Constructs, and a few Large Flow Features. None is known to be active at present, but our data is very limited. Thus, while most of these volcanoes are probably long dead, a few may still be active."

    Actually, NASA's Magellan spacecraft used radar to map 98% of the Venusian surface, per the JPL webpage http://www2.jpl.nasa.gov/magellan/ which begins as follows:

    "Magellan MIssion to Venus

    "Welcome to the Magellan Project home page!

    "NASA's Magellan spacecraft made a dramatic conclusion to its highly successful mission at Venus when it is commanded to plunge into the planet's dense atmosphere Tuesday, October 11, 1994. During its four years in orbit around Earth's sister planet, the spacecraft has radar-mapped 98 percent of the surface and collected high-resolution gravity data of Venus. The purpose of the crash landing is to gain data on the planet's atmosphere and on the performance of the spacecraft as it descends.

    "This home page offers Venus images taken by Magellan and other highlights from the mission."

    The ESA's satellite was more recent, and it took infra-red imaging of the planet, which is more useful when determining which volcanoes would have been most recently active.

    It's true that we just don't know. Venus' surface shows evidendce of having been recently resurfaced, but does not appear to have tectonic plates, which has lead some astronomers to believe that all the volcanoes erupt at once, then go dormant while pressure and heat build up below the crust.

    That's just one model, and I think it's possible that the surface just looks young because the high temps and thick atmosphere keep it constantly re-paving. Further observation is definitely needed. All we no so far is that none are active right now.

    personally/optically viewing volcanoes on Venus is a tad difficult
    Maybe you dont realise that Venus is totally shrouded in cloud :)
