How was Earth formed? New Research reveals exciting answers regarding similar chemical origin in Earth and Planetary Objects

In 2005, a small variation in 142Nd was detected between chondrites, which are stony meteorites, considered essential building blocks of the Earth and terrestrial rocks

  • Neodymium-142 (142Nd) is one of seven isotopes found in the chemical element neodymium which may explain the origin of Earth and Solar system
  • In 2005, the small variation in 142Nd was detected between chondrites, which are stony Meteorite
  • These results were widely interpreted as an early differentiation of the interior of the Earth and these chondrites within the first 30 million years of its history

Ontario, September 15, 2016: Neodymium-142 (142Nd) is one of seven isotopes found in the chemical element neodymium which is widely distributed in the Earth’s crust and most commonly used for magnets in commercial products like microphones and in-ear headphones.

These results were widely interpreted as an early differentiation of the interior of the Earth (including the crust and mantle) and these chondrites within the first 30 million years of its history.

The new results published in the journal Nature from Bouvier and Boyet showed that these differences in 142Nd were in fact already present during the growth of Earth and not introduced later, as was previously believed.

“How the Earth was formed and what type of planetary materials were part of that formation are issues that have puzzled generations of scientists. And these new isotopic measurements of meteorites provide exciting answers to these questions about our origins and what made the Earth so special,” said Audrey Bouvier, Cosmochemist at the Western University.

    While everyone is busy making this planet come to an end
    Its really nice to read how Earth came into existence.

  • Anubhuti Gupta

    Tracing our origins is indeed a very curious and important subject.

  • Manthra koliyer

    Mother Earth has given us lots and we should preserve it.

  • Arya Sharan

    Knowing about the origin and reason of Earth’s existence is a great thing to know.

WMO: Earth Witnesses Record Breaking Temperature in June 2019

Nullis says the heat wave will affect millions of people from the Great Plains to the East Coast. She says temperatures of 38 to 43 degrees Celsius are expected

The World Meteorological Organization (WMO) says the world’s leading weather stations confirm the Earth has just had the warmest June on record, since record keeping began in 1880.

Meteorologists say nine of the 10 warmest Junes on record have occurred since 2010.  The 10th record-holder was in June 1998.  WMO says last month’s record-breaking temperatures were felt across the globe.  It says no land or ocean areas have recorded cold temperatures in June.

But WMO spokeswoman Claire Nullis says temperatures are only part of the story. “June saw the second-smallest Arctic sea ice extent for the month on record and the lowest Antarctic sea ice extent,” she said. “… There is a lot of concern this week about fires in Greenland as part of the unusual spike in Arctic blazes.”

Nullis notes Alert, Canada, the northernmost settlement on Earth, reached a high of 21 degrees Celsius (70 degrees Fahrenheit) for the first time in history a few days ago.  And now, she says the U.S. National Weather Service is issuing warnings about dangerous heat and humidity through this weekend in two-thirds of the United States.

Nullis says the heat wave will affect millions of people from the Great Plains to the East Coast.  She says temperatures of 38 to 43 degrees Celsius are expected. “Twenty to 30 record high temperatures are expected and no relief at night is expected,” she said. “Again, the National Weather Service is predicting that about 123 minimum overnight temperature records may be tied or broken.”

Scientists say heatwaves such as the one Earth is currently experiencing are consistent with climate scenarios. They predict more frequent, drawn out and intense heat events as greenhouse gas concentrations lead to a rise in global temperatures. (VOA)
