Nebulae are among the most breathtaking and enigmatic objects in our universe. These vast clouds of gas and dust are the birthplaces of stars, the remnants of stellar explosions, and cosmic canvases painted with the raw materials of creation. The study of nebulae offers profound insights into the life cycles of stars and the chemical evolution of galaxies.

Our solar system consists of the Sun, eight planets, numerous moons, dwarf planets, asteroids, and comets. It is a vast and fascinating place, constantly revealing new insights through scientific exploration.

ere’s an overview of Ancient Astronomers and their key contributions to early astronomy:

Here’s a breakdown of the main types of planets, based on their physical characteristics, composition, and location—used in both our solar system and exoplanet classification:

What Is Microgravity?

Microgravity occurs when objects are in free fall, such as astronauts orbiting Earth in the International Space Station (ISS). It creates the illusion of weightlessness but still involves small gravitational forces.

What Is Space Debris?

Space debris (also called “space junk” or “orbital debris”) refers to non-functional, human-made objects in Earth’s orbit. This includes:

Radiation is one of the most dangerous and persistent challenges for astronauts during space missions, especially for long-duration travel beyond low Earth orbit (LEO), like missions to the Moon or Mars.

Here are some major challenges in space exploration that scientists, engineers, and astronauts face:

1. Human Spaceflight Missions

Apollo Program (NASA, USA)

• Goal: Land humans on the Moon and return them safely

The Sun isn’t just the center of the solar system—it is the solar system, in terms of mass.

Here are some of the most famous comets in history, known for their brightness, long tails, or dramatic appearances near Earth:

Saturn is home to one of the most fascinating and diverse collections of moons in our solar system. Here's an overview of its most notable moons and key facts:

Galaxies are vast systems of stars, gas, dust, and dark matter bound together by gravity. Astronomers classify them into several types based on their shape and structure. Here's a breakdown of the main types of galaxies:

Here’s a breakdown of the main types of orbits, categorized by altitude, shape, and purpose. Each orbit serves a specific function in satellite and space mission design:

How Gravity Works: A Simple Explanation

Here are the key characteristics of the Moon, Earth’s only natural satellite:

General Space Facts

1. Outer Space Begins at the Kármán Line
   This imaginary boundary is 100 kilometers (62 miles) above sea level — officially marking the start of outer space.

Here’s a look at some of the major space programs around the world that are shaping humanity’s exploration beyond Earth:

Stars are categorized by their temperature, color, mass, and life stage. Here are the main types of stars:

Estimating the number of stars in the known (observable) universe is incredibly complex, but here's the best approximation based on current astronomical knowledge:
