NASA Researchers Discover 7 Earth-Sized Exoplanets Nearby

With the discovery of seven Earth-sized planets orbiting a dwarf star, we are on the right track to find another habitable system! What makes this discovery by NASA’s Spitzer Space Telescope special is that this is the first time that a series of Earth-sized planets have been found around a single star, hence setting a new record for seemingly habitable planets around a single star outside our solar system. All seven planets may have water in the liquid state and be habitable in the future with...

Barren Island volcano in the Andaman basin is active

Barren Island volcano, located 140 km Northeast of Port Blair, is active and spewing smoke and lava again as reported by a team of scientists from CSIR-National Institute of Oceanography (CSIR-NIO), Goa. The scientific team led by Chief Scientist Dr Abhay V Mudholkar, on board CSIR-NIO’s research ship RV Sindhu Sankalp were busy collecting sea floor samples in the Andaman Basin near the Barren volcano when they witnessed the sudden spewing of ash on January 23,2017. The team immediately sprang...

Zealandia- The discovery of earth’s hidden continent

A group of scientist in Australia who have been working and gathering data for the past twenty years claim that New Zealand sits atop a previously unknown continent which is 94% underwater. Eight GNS Science geologists headed by Nick Mortimer along with colleagues from Victoria University, the Geological Survey of New Caledonia, and the University of Sydney summarize the evidence that 4.9 million square kilometers of the South West Pacific Ocean is underlain by a submerged continent. The lead...

Record warmest year third time in a row

NASA has declared this year to be the hottest year yet recorded. September turned out to be the warmest in modern temperature monitoring of 137 years. The recent findings follow record-breaking monthly anomalies throughout this year, leading the agency to believe that because of the highs reported so far. The first nine months of 2016, as reported by NASA, were characterized by much-warmer-than-average conditions across most of the globe's surface, resulting in the warmest January–September...

Why didn’t the human race end by year 2012?

Many people were worried about the possibility of a natural calamity towards the end of 2012 leading the human race to perish. Perhaps the first predictions rose from Mayan astrology – chalked out in a calendar built out of stones indicating an abrupt end of the world on 21 December 2012. But, mass extinction on Earth needs to take clues from a geological perspective to be anywhere near the truth.

The Glacial Lake Outburst Prone Regions of the Himalaya

Glaciers work as a water tower, sustaining the lives of millions downstream. The volumes of these glaciers vary - remaining sensitive to global temperature conditions. The glaciers have embedded within it many lakes which follow a seasonal pattern of freeze and thaw. With continuing warming trends, many glaciers are melting rapidly, giving birth to a large number of glacial lakes. These ‘moraine dammed’ lakes are comparatively feeble and its unexpected outburst is a threat to life, asset and infrastructure, downstream.

Preserving the Perishing Paradises

Antarctic, the cold oceans surrounding it and the greater parts of Arctic are often conceptualised as the 'common heritage of mankind' - most enchanting, picturesque and pristine - sustaining the complex ocean-atmosphere coupled system of our planet and thereby ensuring the sustenance of life itself. While appreciating the need for development, it is argued by environmentalists that the Earth has physical and biological limits and it is of utmost importance that these limits are honoured.

Mysteries of the Ancient Waters

Penetrating Lake Vostok in Antarctica, without mitigating the potential sources of contamination is likely to jeopardise the pristine nature of the Lake which makes it unique. The lubricants and anti-freeze used to bore a hole through the ice to reach the waters below may taint the very microorganisms that scientists are trying to discover.

Indian Plate Movement | Earthquake and Tsunami Risk Zones

The Indian plate, separated from the Antarctic, started moving to the north northeast about 180 million years ago. The present day movement of the Indian plate from the Carlsberg spreading ridge results in collision in the Himalaya and subduction in the Andaman-Sumatra. These plate margins, therefore, are the major seismic belts of the moving Indian plate.
