Astrophotography using Smartphones

               Astrophotography is a fascinating combination of art and science that involves capturing stunning images of the night sky and celestial objects. Many people believe that astrophotography requires expensive and complicated equipment, such as telescopes, cameras, and filters. However, with just a smartphone and a few simple accessories, anyone can capture beautiful photos of the stars, planets  and even the Milky Way. In this article, we will show you how to get started with astrophotography using smartphones. We will discuss what you need to prepare, how to set up your camera. By following these steps, you will be able to impress your friends and family with your amazing images of the night sky.   To get started with astrophotography, you need a smartphone.

Linear Time and Its Paradoxes

Time is one of the most fundamental aspects of our experience, but also one of the most mysterious and controversial. How do we understand time? Is it a fixed and objective reality, or a subjective and relative construct? Is time travel possible, and if so, what are the implications for causality and free will? In this article, we will explore the concept of linear time and its paradoxes, and explain why it is unlikely to be true. What is Linear Time? Linear time is the idea that time has a beginning and an end, and that it flows in one direction from past to future. This view of time is influenced by the Christian worldview, which posits that time was created by God at the moment of Genesis, and that it will end at the Last Judgement. Linear time implies that there is a clear distinction between past, present and future, and that events are ordered by their temporal sequence. Linear time is also compatible with some scientific theories, such as the Big Bang model of cosmology, which s...

Space Junk: A Growing Threat to Our Satellites and Space Missions

Space junk, also known as orbital debris, is any human-made object that orbits the Earth but has no useful function. It includes defunct satellites, rocket stages, fragments from collisions and explosions, and even paint flakes and dust. According to the European Space Agency (ESA), there are more than 34,000 objects larger than 10 cm, about 900,000 objects between 1 and 10 cm, and more than 128 million objects smaller than 1 cm in orbit around the Earth. These numbers are expected to increase as more satellites are launched and more collisions occur. Why is space junk a problem? Space junk poses a serious threat to our satellites and space missions for several reasons. First, space junk can damage or destroy operational satellites that provide vital services such as communication, navigation, weather forecasting, and Earth observation. A collision with a small piece of space junk can create a dent or a hole in a satellite, affecting its performance or rendering it useless. A collision...
