Our perception of a volcano is reddish fire and destruction, which is conditioned by the images of molten lava wreaking havoc on human settlements and animal habitats. Yet, there is more to volcanoes than that, as pointed out by a report in sciencenews.org which states that a new study suggests how two billion years ago such volcanic eruptions on the moon led to water vapour becoming ice on its poles. The details of this study have been reported in the Planetary Science Journal of May month. The presence of ice on the moon was confirmed in 2009 and since then it has been argued as to how it came into being on the moon. The options discussed included comets, charged atoms carried by the solar wind, asteroids or that it originated on the moon itself because of eruptions in volcanoes between 4 to 2 billion years ago. Planetary scientists from University of Colorado, Boulder Andrew Wilcoski observed: “It’s a really interesting question how those volatiles [such as water] got there. We stil

  New York’s Stony Brook University (SBU) team of researchers were in for a surprise when they spotted gentoo penguin colonies on Andersson Island of Antarctica and also on an archipelago which has remained unexplored and is located off the Antarctica Peninsula’s northern point. According to a report in smithsonianmag.com, these places are some of the southern-most for gentoo breeding. Interestingly, gentoo penguins favour places that are warmer to raise their offspring and till recently found these regions too icy for their choice. That doesn’t seem so now as change in climate is helping them to expand their habitat – “gentoofication” as some scientists refer to it as. Talking to Mongabay, Heather Lynch, said: “It’s may be a cliché at this point, but they’re the canary in the coal mine for climate change because they’re so closely tied to those sea ice conditions.” Read More
