The Sun is the star at the centre of our solar system and is almost three quarters Hydrogen, whilst most of the remaining mass is Helium. At around 4.6 Billion years old it is considered to be middle-aged (or a Yellow Dwarf) having already burned off about half of its store of Hydrogen. It has a surface temperature of 5500 °C compared to the Earths -88 to 58°C but inside, the temperature can reach 15 million degrees Celsius: At the Sun’s core, energy is generated by nuclear fusion, as Hydrogen converts to Helium.
The solar flares that are seen in this image occur when magnetic energy is released by the Sun during magnetic storms, which we see as sunspots. In sunspots, the magnetic lines are twisted and they spin, much like a tornado would on Earth. The Sun generates a solar wind, which is a stream of charged particles, which travel through the Solar System at approximately 450 kilometres per second. Solar wind occurs where the magnetic field of the Sun extends into space and observers near the poles on Earth sometimes see beautiful lights in the night sky known as auroras, that are the result of the solar wind interacting with the Earth's magnetic field and atmosphere.
Eventually, about 130 million years after all the Hydrogen has been burned, the Sun will expand to the point that it will engulf Mercury, Venus and the Earth and at this stage it will have become a Red Giant. The final stage of the Sun's life will occur when it collapses, retaining its enormous mass, but containing the approximate volume of our planet. When this happens, it will be called a White Dwarf.
Light from the Sun takes eight minutes to reach Earth but although this energy reaches Earth in a few minutes, it will already have taken millions of years to travel from the Sun’s core to its surface.
Please note that this range of jewelry is not 100% waterproof and should be removed before bathing. You may also wish to use a silver cleaning cloth from time to time to maintain the sparkle!
These beautiful earrings contain high resolution images of the Sun set into a nickel free silver plated base. The wires are sterling silver and there is the option of having transparent Czech lustre glass beads added for extra sparkle! They are presented either on a beautiful photo card with envelope and with information of the planet on the reverse or in a small jewellery box with descriptive photo card. They come in two sizes - small 1.2cm gem earrings are approx. 3cm long with bead, (2cm without) and the large 1.6cm gem earrings are approx. 3.5cm. long with bead (3cm without).
