An asteroid is a rocky body that orbits Sun and is primarily found in the region known as the asteroid belt, located between the orbits of Mars and Jupiter. These sky bodies are remnants from the early solar system, formed about 4.5 billion years ago during the formation of the planets. Unlike planets, asteroids are much smaller, irregularly shaped and lack atmospheres. Their sizes range from a few meters to hundreds of kilometers, and the largest asteroid, Ceres, is also classified as a dwarf p

The Sun is the source of everything on Earth. Our light, our heat, our seasons—all are made possible by the Sun’s steady luminosity. But a major question arises in the mind: What happens when the Sun one day dies? First, it is essential to understand: The Sun is not a star capable of exploding like a supernova. The reason is its relatively small mass. Supernova explosions occur only in massive stars with at least eight to ten times the mass of the Sun. Therefore, the Sun’s fate is not to explode

HD 219134 b (HR 8832 b) is a super-Earth located just 21.25 light years from Earth in the direction of the Cassiopeia constellation. This planet is one of the closest known transiting exoplanets. It orbits a K-type star named HD 219134. The high-precision measurement of both its mass and radius has made HD 219134 b an important reference point for scientific studies on the densities and internal structures of rocky exoplanets. Based on the obtained data, its dense structure suggests that it like

Planets were once described as “wandering points of light” in the sky. At that time, people believed Earth was at the center of the universe. But as science advanced, telescopes were invented and astronomers made new discoveries. We now know that planets orbit a star, can vary in shape and size, and each moves along its own unique orbit. So why is a celestial body classified as a “planet”? Scientists spent years observing the sky to find the answer. Now I will share that answer with you—but don’

Dwarf planets are celestial bodies that orbit the Sun, possess sufficient mass for their self-gravity to overcome rigid body forces so that they assume a nearly spherical shape, but have not cleared their orbital paths of other objects of comparable size. The key distinction between traditional planets and dwarf planets is the orbital clearance criterion established by the International Astronomical Union (IAU) in 2006.【1】 According to this definition, dwarf planets must orbit a star, have suffi

Photovoltaic (PV) technology is a method of generating electrical energy from sunlight. PV cells are made from semiconductor materials that directly convert sunlight into electricity. These cells are typically a few centimeters in size and each generates about 1-2 W of power. Photovoltaic cells are often coated with protective materials such as glass and plastic to safeguard them from external factors. OPERATING PRINCIPLE OF PV CELLS PV cells are stimulated by photons from sunlight, which releas

Solar Apex is an astronomical term that denotes the direction of motion of the Sun System within the Milky Way Galaxy. The Sun and all associated planets, galaxy are moving along a specific orbit. During this motion, the direction in which the Sun is presumed to be advancing is referred to as the Solar Apex.The Solar System is an astronomical system composed of planets, dwarf planets, moons, asteroids, comets, and other celestial bodies bound together by the gravity of the Sun. The Solar System

Asteroid mining is a space activity focused on extracting and utilizing water, volatile compounds, and metal-rich raw materials from Solar System asteroids. This approach aims to enhance the sustainability of space missions and transform space logistics by leveraging extraterrestrial resources. The accessibility of near-Earth asteroids and their diverse compositions have made these bodies significant targets for scientific and technical studies. Resource Potential of Asteroids Asteroids contain

Our planet travels a long journey around the Sun in space. During this journey, when calendars show June 21, a unique natural phenomenon occurs in the sky and on Earth. This event is called the summer solstice. The summer solstice is astronomically recognized as the beginning of summer in the Northern Hemisphere—that is, the upper half of Earth where our country, Türkiye, is located.
