"As scientists we want to discover and explore anything provided it gives us opportunity to explore new vistas of universe. Solve every question and go into depths of every single thing; from atoms to the universe. But unfortunately, our lives aren't as long as the life of the universe which makes it difficult for us to explore it. So we need to start exploring the most fascinating and critical things; objects that based on some general theories which can be used for the similar things.

I specifically chose lapetus as its not only interesting but unique in so many ways. The main difference that we first notice and is the trade-mark of lapetus is that it is half dark and half bright. As scientists we need to know why this phenomenon is only present in the moon lapetus, not in any other object in the known universe. What makes it so? There are many theories to it but we must be sure as this could be a principle of the universe. And to achieve this, we must explore lapetus with depth and deep understanding.

It is said that the leading side of this moon is dark as it gets hit by dust particles which are absorbed by the surface results in erosion and dims the surface. One of the possible reasons could be dust charging. The trailing side on the other hand gets no resisted particles so glows. But does it prove why there are so many patches and craters which are both dark and bright on either side of the moon? Or the fact that no explosion or charge is created when there is so many resistances?

In the brains of scientists curiosity is what gets them started and it be a huge lie to not be curious about how the bulk is created. And exactly on the equator. It could be the reason that in the early stage of the universe the rotation of the two hemispheres might be different and as the time passes it slows down and a ridge was appeared at the poles. The same rotational difference is known on the sun. It disintegrates and becomes uneven and so another theory comes that once it must have been a ring and this bulk might be it's remain.
lapetus has similar characteristics to that of our moon as it's tidally locked to its planet. Also that the ridge creates mountains higher than of our highest mountain and also the fact that its temperature is warm.

lapetus is highly interesting and its exceptions to theories make us rack our brains till we find a solution. By getting deeper and deeper into its conditions and happenings nor will we move towards a better answer but also to the evolution of the universe. Its walnut shape, two very different hemispheres with similar features to Earth's moon are such traits that can only and only, be seen in lapetus which makes it our first choice to be discovered further."
