Its temperature is estimated to be about 5,500-6,000 degrees (Celsius), similar to the sun's surface temperature," Tkalčić said. "If we were somehow able to dismantle the Earth by removing its mantle and the liquid outer core, the inner core would appear shining like a star. Indeed, it is a solid ball, approximately the size of Pluto and a bit smaller than the moon," said Australian National University geophysicist and study co-author Hrvoje Tkalčić. "I like to think about the inner core as a planet within the planet. The inner core's outer shell and its newly confirmed innermost sphere both are hot enough to be molten but are a solid iron-nickel alloy because the incredible pressure at the centre of the Earth renders it a solid state. Our study becomes possible thanks to the unprecedented expansion of the global seismic networks, particularly the dense networks in the contiguous US, the Alaskan peninsula and over the European Alps," Pham added. "We analysed digital records of ground motion, known as seismograms, from large earthquakes in the last decade. "We may know more about the surface of other distant celestial bodies than the deep interior of our planet," said observational seismologist Thanh-Son Pham of the Australian National University in Canberra, lead author of the study published in the journal Nature Communications. The new research studied waves from 200 quakes with magnitudes above 6.0 ricocheting like ping pong balls up to five times within the planet. Until now, scientists were able to detect these waves bouncing up to twice, from one side of Earth to the other and then back. The increasing sophistication of seismic monitoring enabled this to be confirmed.Įarthquakes unleash seismic waves that travel through the planet and can reveal the contours of its interior structure based on the changing shape of the waves. Scientists in 2002 proposed that lurking within this inner core was an innermost section separate from the rest, akin to a Russian Matryoshka nesting doll. This metallic inner core, about 2,440m wide, was discovered in the 1930s, also based on seismic waves travelling through Earth. The planet's internal structure comprises four layers: a rocky crust on the outside, then a rocky mantle, an outer core made of magma and a solid inner core. Researchers on Tuesday (Feb 21) said an intensive study of Earth's deep interior, based on the behavior of seismic waves from large earthquakes, confirmed the existence of a distinct structure inside our planet's inner core - a wickedly hot innermost solid ball of iron and nickel about 1,350km wide.Įarth's diameter is about 12,750km. The actual centre of the Earth is nothing like this fanciful depiction - and in some ways is even more dramatic. Along with a variety of Wiccan rituals and spell-casting, you will discover how to conjure positivity to attract the results you seek.WASHINGTON: In Jules Verne's classic 1864 novel Journey to the Center of the Earth, adventurers descend through an Icelandic volcano into a vast underground world populated by prehistoric creatures as they explore our planet's interior. This book also explains what manifestation is and isn't, and it teaches you all the basics of Wicca, such as how to work with solar and lunar cycles, deities, symbols and the five magical elements, create a sacred space and a 'book of shadows' to empower and amplify your intentions and manifestations. It also tells you the secret magic of the numbers 3,6, 9, and their use in manifestation techniques. This book shows you how to connect to your inner witch, cultivate confidence, self-belief, awareness and how to set powerful intentions. By drawing on Wiccan wisdom, you will amplify and enhance all aspects of realising those desires. Manifesting your goals and dreams is about making the things you want to happen, well, happen. The art of manifestation is not only about connecting to the universe to help you to achieve an outcome, but also about self-understanding, self-discovery and truly believing in your desires and intentions. A guide to harnessing Wiccan wisdom to manifest your own dreams.
