The Formation of the Solar System

4.6 Billion years ago

Information

Our Solar System is part of the Milky Way Galaxy that contains billions of other stars. Our Sun is thought to be a third generation star created from the materials from two previous generations of stars which had reached the end of their lives and exploded sending their material out into the universe. About 4.6 billion years ago the solar system began to form within a molecular cloud, a concentration of interstellar dust and hydrogen gas. The cloud contracted under its own gravity and our proto-Sun formed in the hot dense centre. The remainder of the cloud formed a swirling disk called the solar nebula. It was within this solar nebula that beginnings of planets were born as dust and ice particles came together in a process called “accretion”. These planetesimals continued to grow, their gravity coming to influence each other’s motions causing more collisions and accretion and so creating proto-planets. This continued until there were only four large bodies in the inner solar system, Mercury, Venus, Earth and Mars. In the cold outer nebula much larger proto-planets formed, Jupiter, Saturn, Uranus, and Neptune. Our Moon was formed shortly after the formation of the Earth; the Earth was hit by an object half its size which disintegrated along with the outer layers of the Earth. The debris from this formed a ring around the Earth which accreted, clumped together, to form the Moon.

Holy Waters Run Deep

1397

Information

A peculiar landscape feature in Longthorpe has been the source of several myths and tall tales over the years and debate is still ongoing as to its origins. The holywell, situated in land to the west of Thorpe Hall, is also known as St Cloud's well. It was said to have been the home of hermit St Cloud in the past. It's first reference as a holy well is from a document dated to the Abbotship of William Genge (1396-1408), although the location was referenced earlier than that. (1) The well is in fact a natural spring which was contained under a mound in the eighteenth century to form a grotto. One myth surrounding the well is that the mound contained an entrance way to tunnels that led to the Cathedral. Although the land was once controlled by the Cathedral, it is geographically impossible for a tunnel to have existed between those two sites. Similarly the myths about hermits living there cannot be true due to the date that the mound was built. The spring feeds a series of medieval fishponds, which are still in place. Again there is some uncertainty about their origin. One idea is that they were used originally by the Cathedral and later by occupants of Thorpe Hall. Another argument is that they were created by the occupants of Longthorpe Manor. This suggestion is the favoured option because the Cathedral had their own fish ponds. Although eating fish that had swum in the waters of a holy well might have appealed to the religious community.
