What are the Parts of the Sun?

13 Sep , 2016 by Fraser Cain

Much like Earth, the Sun is not a single object, but is made up of layer. Each layer is responsible for a different function that adds up to it providing us with all the heat and light we need to live

What Is The Surface of Neptune Like?

20 Apr , 2016 by Matt Williams

As a gas giant, Neptune has no surface, in the traditional sense. But atop its cloud layers, some pretty amazing things are happening

What If We Dug a Tunnel Through the Earth?

27 Nov , 2015 by Fraser Cain

If we could dig a tunnel through the Earth, what would happen? And is this even possible?

Getting to the Core of Earth’s Falling Snow

2 Feb , 2012 by Jason Major

[/caption] An international plan is unfolding that will launch satellites into orbit to study global snowfall precipitation with unprecedented detail. With the upcoming Global Precipitation Measurement (GPM) satellites, for the first time we will know when, where and how much snow falls on Earth, allowing greater understanding of energy cycles and how best to predict […]

New Insights into the Moon’s Mysterious Magnetic Field

30 Jan , 2012 by Irene Antonenko

Ever since the Apollo era, scientist have known that the Moon had some kind of magnetic field in the past, but doesn’t have one now. Understanding why is important, because it can tell us how magnetic fields are generated, how long they last, and how they shut down. New studies of Apollo lunar samples answer […]

How the Moon Became Magnetized

10 Nov , 2011 by Jason Major

[/caption] It’s been a mystery ever since the Apollo astronauts brought back samples of lunar rocks in the early 1970s. Some of the rocks had magnetic properties, especially one collected by geologist Harrison “Jack” Schmitt. But how could this happen? The Moon has no magnetosphere, and most previously accepted theories state that it never did. […]

Hubble Finds “Oddball” Stars in Milky Way Hub

25 May , 2011 by Jason Major

Astronomers using the Hubble Space Telescope to peer deep into the central bulge of our galaxy have found a population of rare and unusual stars. Dubbed “blue stragglers”, these stars seem to defy the aging process, appearing to be much younger than they should be considering where they are located. Previously known to exist within […]

Why is the Center of the Earth Hot

15 Oct , 2010 by Tega Jessa

[/caption] It interesting that we have explored further into space than we have explored the depths of the Earth. The main reason for that is the pressure and the heat. We know through seismography that temperatures in the inner parts of the Earth actually exceed the surface temperature of the Sun! That is pretty hot. […]

Earth’s Layers For Kids

6 Oct , 2009 by Fraser Cain

My son recently came back from a science day camp with one of the coolest things. It was a model of the Earth that he had created out of modeling clay. It showed the internal structure of the Earth, and because he built it, he was able to remember all of the layers of the […]
