Using a series of very technical tests, scientists from the French research facility CEA have determined that the Earth's core is roughly 6,000 degrees Celsius. That is approximately 1,000 degrees hotter than the temperature obtained by tests in the 1990s.
These new figures show that the center of the Earth is just as hot as the surface of the sun.
The experiment that supplied the new temperature used X-rays to probe tiny samples of iron at extraordinary pressures to examine how the iron crystals form and melt. The BBC reported that "To replicate the enormous pressures at the core boundary - more than a million times the pressure at sea level - they used a device called a diamond anvil cell - essentially a tiny sample held between the points of two precision-machined synthetic diamonds.
Once the team's iron samples were subjected to the high pressures and high temperatures using a laser, the scientists used X-ray beams to carry out "diffraction" - bouncing X-rays off of the nuclei of the iron atoms and watching how the pattern changed as the iron changed from solid to liquid."

Education has been turned upside down in light of the coronavirus pandemic. Schools across the country have been closed, and students thrust into remote learning. Teachers, in many cases, have had little or no time to really prepare to deliver this different form of instruction.
Parents have also been tasked with helping to guide students, as they juggle their own work from home.
Some education leaders are concerned about students falling far behind in their studies, and...
With many schools being postponed and even canceled for the rest of the school year, we have been given the gift of time. Even though we are scared, anxious, worried, and impatiently waiting for this to be over, we can go out and do things that we may have put off before this week or said there is no time in our day. I urge you, as an Early Childhood Professional, to use this time wisely. Here are some things you...
If you’re a teacher, you know that teaching can be a highly demanding, stressful job.
Unlike other professions, there is little if any downtime. You must constantly be on and present when teaching children or teenagers. Take your eye of the ball for a moment, and the opportunity for learning is gone (and students behave badly. Like sharks in water, I think they can smell the blood).
But seriously, teachers need a practical, sustainable method of self-care and, right now,...
With more and more schools closing as a precaution due to the coronavirus spreading in the United States, parents might find these free resources of interest to use with their children. Teachers who are working with students online, might also find these education FREEBIES of value. (Grades 4 and up)
Hoping our world gets back to some normalcy, soon. Stay healthy!
