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:

What Are Constellations?

Constellations are patterns formed by groups of stars that resemble figures, animals, or objects. While the stars in a constellation may be light-years apart, from Earth they appear close together and form recognizable shapes. Across history, people used constellations for storytelling, navigation, and marking seasons. The International Astronomical Union officially recognizes 88 constellations.

Planet Profile: Venus

1. Basic Facts

Venus, the second planet from the Sun, is often called Earth’s twin due to its similar size, mass, and composition. However, beyond these similarities, Venus is an incredibly hostile world with scorching temperatures, crushing atmospheric pressure, and toxic clouds. It has a diameter of 12,104 km (7,521 miles), making it slightly smaller than Earth. Unlike Earth, Venus has a thick, dense atmosphere composed mostly of carbon dioxide, trapping heat and creating the hottest planetary surface in the Solar System. Venus has no moons or rings, and its surface is dominated by vast volcanic plains, mountains, and deep craters. Despite its extreme conditions, Venus has fascinated astronomers for centuries and remains an important target for future exploration.
