The Mini - Star Trail is an art installation and at the same time a short themed trail that is specially illuminated at night. On a short stretch of 105 m in the centre of Steinegg / Collepietra, we encounter 11 selected stars. Away from the sun, these are laid out in the correct scale. A light year here is 4 cm. You have to imagine that a light year is the enormous distance that light travels in one year. You have to bear in mind that light travels almost 300,000 km in one second. That is 9.46 trillion kilometres in one year.
But what is a star? A star is a gigantic burning ball of gas. It consists of hydrogen and helium. When hydrogen burns, energy is released that we perceive as light and heat.
How big is a star anyway? There are many stars that are significantly larger than our star, the Sun. For example, the star Antares is 820 times bigger than the Sun. In order to better understand these dimensions, we will find a comparison of the size of the star and the sun at the respective stations of the mini star trail.
Why do stars shine in different colours? When observing the starry sky closely, we can also see with the naked eye that stars shine in different colours: reddish, bluish, white, etc. This has to do with the different surface temperatures of the stars.
In the evening and at night, the stars on the Mini - Star Trail are also illuminated from the inside with the right mixture of light. So it is now possible to walk along the romantically illuminated Mini - Star Trail in the centre of Steinegg / Collepietra in the evening and get to know exactly these peculiarities of the starry sky.
This theme trail is financed by the Interreg project Skyscape. The measures of the Interreg project "Skyscape" are supported by the European Regional Development Fund and Interreg V-A Italy-Austria 2014-2020.
