Planets are large celestial bodies that orbit a star, such as the Sun in our solar system. They are massive enough to be rounded by their own gravity, but not massive enough to initiate nuclear fusion like stars. Planets can be divided into two main types:
1. Terrestrial Planets: These are rocky planets with solid surfaces, including Mercury, Venus, Earth, and Mars. They are smaller, closer to the Sun, and have few or no moons.
2. Gas Giants and Ice Giants: These are larger planets primarily composed of gases or ices. Jupiter and Saturn are gas giants, made mostly of hydrogen and helium. Uranus and Neptune are ice giants, containing more ices like water, ammonia, and methane. Planets do not produce their own light but reflect the light of their star. In addition to orbiting stars, some planets have moons, rings, and unique surface features like mountains, volcanoes, and canyons.
Here you can see my planetary images, categorized by planet., Just click on the image of the planet to see the corresponding pictures, hope you'll enjoy.

Moon

The Moon is Earth's only natural satellite. Its diameter is about one-quarter of Earth's (comparable to the width of Australia),making it the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet. It is larger than all known dwarf planets in the Solar System. The Moon is a planetary-mass object with a differentiated rocky body, making it a satellite planet under the geophysical definitions of the term. It lacks any significant atmosphere, hydrosphere, or magnetic field. Its surface gravity is about one-sixth of Earth's at 0.1654 g—Jupiter's moon Io is the only satellite in the Solar System known to have a higher surface gravity and density.

Galaxies

Galaxies are vast systems composed of stars, gas, dust, dark matter, and interstellar material, all bound together by gravity. They come in various shapes, including spiral (like the Milky Way), elliptical, and irregular. Galaxies can range in size from a few million to trillions of stars. They often contain star clusters, nebulae, and sometimes supermassive black holes at their centers. Galaxies can be part of larger structures, such as galaxy groups and clusters, and are fundamental building blocks of the universe, forming over billions of years.

Sun

The Sun is the star at the center of the Solar System. It is a nearly perfect ball of hot plasma,[18][19] heated to incandescence by nuclear fusion reactions in its core. The Sun radiates this energy mainly as light, ultraviolet, and infrared radiation, and is the most important source of energy for life on Earth.
Sun's radius is about 695,000 kilometers (432,000 miles), or 109 times that of Earth. Its mass is about 330,000 times that of Earth, comprising about 99.86% of the total mass of the Solar System.[20] Roughly three-quarters of the Sun's mass consists of hydrogen (~73%); the rest is mostly helium (~25%), with much smaller quantities of heavier elements, including oxygen, carbon, neon, and iron.

Nebulae

Nebulae are vast clouds of gas and dust in space, often serving as the birthplaces of stars. They are formed from ionized gases, primarily hydrogen and helium, and can vary in appearance. There are several types of nebulae:
Emission Nebulae: These glow brightly due to the ionization of their gases by nearby hot stars, emitting visible light (e.g., the Orion Nebula).
Reflection Nebulae: These don’t emit light but reflect the light of nearby stars, often appearing blue (e.g., the Pleiades Nebula).
Planetary Nebulae: These are formed when a star expels its outer layers at the end of its life cycle, leaving behind a glowing shell of gas (e.g., the Ring Nebula).
Dark Nebulae: These are dense clouds of gas and dust that block light from objects behind them, appearing as dark patches in space (e.g., the Horsehead Nebula). Nebulae are critical to the process of star formation, and their stunning visuals have made them a subject of fascination for astronomers and astrophotographers alike.

Comets

Comets are icy celestial bodies that originate from the outer regions of the solar system. They are composed primarily of dust, rock, and ices such as water, carbon dioxide, methane, and ammonia. When a comet approaches the Sun, the heat causes the ices to vaporize, creating a glowing atmosphere called a **coma**, and sometimes a long tail that always points away from the Sun due to solar wind. The tail can extend millions of kilometers into space. Comets are often considered remnants from the early solar system and typically come from regions like the Kuiper Belt and the Oort Cloud. Famous comets include Halley's Comet and Comet Hale-Bopp

Clusters

Clusters refer to groups of stars or galaxies bound together by gravity. There are two main types of clusters: Star Clusters: a) Open Clusters: These are loose, irregular groups of young stars, typically found in the spiral arms of galaxies. They contain a few hundred to a few thousand stars and are not tightly bound, so their stars gradually drift apart over time. An example is the Pleiades in the constellation Taurus. b) Globular Clusters: These are dense, spherical collections of old stars, containing tens of thousands to hundreds of thousands of stars. Globular clusters are tightly bound by gravity and orbit the halos of galaxies. An example is the Hercules Cluster (M13). Galaxy Clusters: These are large structures consisting of hundreds to thousands of galaxies held together by gravity. They are the largest known gravitationally bound structures in the universe. An example is the Virgo Cluster.
