According to the findings of a study published in the journal Science on April 26, the core of our planet is about 1,000 degrees Celsius hotter than it was estimated to be by a study carried out about 20 years ago .
This 
temperature has been detected quite close to the center of our planet ( at the boundary between the inner and outer core , to be more precise ) and is estimated to reach 6,000 degrees Celsius .
The new evidence may help better explain why and how our planet can produce a magnetic field .
As Our Amazing Planet, the temperature difference between the inner core and the mantle (there is a difference of at least 1,500 degrees Celsius), along with rotation the planet's is what causes the magnetic field. reports , to exist
