Cracked, Frozen and Tipped Over: New Clues from Pluto's Past

Introduction

Pluto, the dwarf planet, has always been a mystery to scientists. However, with the help of NASA's New Horizons spacecraft, we are now able to uncover some of the secrets of Pluto's past. In this article, we will explore the latest findings from NASA's New Horizons mission and what they reveal about Pluto's history.

The Discovery of Pluto

Before we dive into the latest findings, let's take a brief look at the discovery of Pluto. Pluto was discovered in 1930 by Clyde Tombaugh, an American astronomer. It was the first object to be discovered in what is now known as the Kuiper Belt, a region of the solar system beyond Neptune that is home to many icy objects.

The New Horizons Mission

In 2006, NASA launched the New Horizons spacecraft with the goal of studying Pluto and its moons. After a nine-year journey, the spacecraft finally reached Pluto in 2015 and began sending back data and images.

The Latest Findings

One of the most interesting findings from the New Horizons mission is the discovery of cracks on Pluto's surface. These cracks are similar to those found on Earth's surface, and they suggest that Pluto may have experienced tectonic activity in the past.

Another discovery is the presence of frozen nitrogen on Pluto's surface. This nitrogen is thought to have come from Pluto's atmosphere, which is mostly made up of nitrogen. The frozen nitrogen is also responsible for the bright patches on Pluto's surface.

The New Horizons mission also revealed that Pluto is tipped over on its side. This means that its axis of rotation is tilted at an angle of about 120 degrees, which is much greater than the tilt of any of the planets in our solar system.

What These Findings Reveal About Pluto's Past

The discovery of cracks on Pluto's surface suggests that the dwarf planet may have experienced tectonic activity in the past. This activity could have been caused by the cooling and contraction of Pluto's interior, which would have led to the formation of faults and cracks on its surface.

The presence of frozen nitrogen on Pluto's surface suggests that the dwarf planet may have had a much thicker atmosphere in the past. This atmosphere would have been able to support the formation of nitrogen ice on the surface.

Finally, the fact that Pluto is tipped over on its side suggests that it may have experienced a collision with another object in the past. This collision could have caused Pluto to be knocked off its original axis of rotation.

Conclusion

The latest findings from NASA's New Horizons mission have given us new insights into the history of Pluto. The discovery of cracks on Pluto's surface, the presence of frozen nitrogen, and the fact that Pluto is tipped over on its side all provide clues about the dwarf planet's past. While there is still much to learn about Pluto, these findings are a significant step forward in our understanding of this mysterious world.
