14 DAY TRIAL // According to a research whose findings were published in the journal Science this April 26, our planet's core is about 1,000 degrees Celsius (roughly 1,800 degrees Fahrenheit) hotter than estimated by a study carried out about 20 years ago.
Thus, the temperature registered fairly close to our planet's center (i.e. at the boundary between the inner and the outer core, to be more precise) is now said to be one of 6,000 degrees Celsius (that's about 10,800 degrees Fahrenheit).
By the looks of it, these new figures help better explain why and how it is that our planet can generate a magnetic field.
As Our Amazing Planet reports, it is the difference in temperature between the inner core and the mantle (which need be one of at least 1,500 degrees Celsius / 2,700 degrees Fahrenheit), together with the planet's spin that cause the magnetic field to occur.
