Comets are small celestial bodies composed of ice, dust, rock, and other volatile compounds. They orbit the Sun in elliptical or elongated trajectories. As a comet approaches the Sun, the frozen material on its surface ...
Emission Nebulae

Emission Nebulae (H II)

Emission nebulae are interstellar clouds of gas and dust that emit light in various wavelengths due to the excitation of their atoms by high-energy radiation, such as ultraviolet light from nearby hot stars. When an ...


Galaxies are vast, gravitationally-bound systems of stars, gas, dust, and dark matter that make up the visible structure of the universe. They come in a wide variety of shapes and sizes, ranging from small, irregularly ...
Globular Cluster

Open Clusters

Open Clusters

Open clusters are groups of young stars that are loosely bound together by gravity. They typically contain anywhere from a few dozen to a few thousand stars, which are all thought to have formed from ...
Planetarische Nebel

Planetary Nebulae

Planetary nebulae are glowing shells of gas and dust that are formed when a low-mass star reaches the end of its life and runs out of fuel to sustain nuclear fusion in its core. As ...
Reflection Nebulae

Reflection Nebulae

Reflection nebulae are clouds of gas and dust in space that are illuminated by nearby stars, causing the nebula to reflect the starlight and appear luminous. They are different from emission nebulae, which emit their ...
