Titan: Saturn’s Moon with Atmosphere, Lakes, and Organic Haze

noor-e-aishaAugust 12, 2025

Titan, Saturn’s largest moon, has a dense, planet-like atmosphere composed mainly of nitrogen (95%) and methane (5%), with a surface pressure slightly higher than Earth’s. Unique among moons, Titan hosts stable bodies of liquid methane and ethane, including lakes, rivers, and seas. The surface temperature is extremely cold, around -179°C (-290°F), and beneath the icy […]

Metis: Jupiter’s Closest Moon Feeding Its Main Ring

noor-e-aishaAugust 11, 2025

Metis is the innermost known moon of Jupiter, orbiting within the planet’s main ring system. It has a very short orbital period, completing a full orbit in just about 7 hours. Because it is so close to Jupiter, Metis is tidally locked, meaning the same side of the moon always faces the planet. Its long […]

Io: Jupiter’s Volcanic Moon Fueled by Tidal Heating

noor-e-aishaAugust 10, 2025

Io is the most volcanically active moon in our solar system, orbiting the planet Jupiter. It hosts over 400 active volcanoes, with lava fountains that can reach dozens of miles into space. The surface features vast lakes of molten silicate lava, such as Loki Patera, which spans more than 200 kilometers in diameter. Io’s surface […]

The Mysterious Planet Vulcan: Myth, Discovery Claims, and Disproof Explained

noor-e-aishaJuly 21, 2025

Vulcan was a proposed planet that some pre-20th-century astronomers believed existed in an orbit between Mercury and the Sun. Speculation about intermercurial bodies—objects orbiting inside Mercury’s path—dates back to the early 17th century. Although the planet was never confirmed, it was seriously considered due to unexplained anomalies in Mercury’s orbit. Early Observations and Hypotheses In […]

Theia and the Giant Impact Hypothesis: Origins of Earth’s Moon

noor-e-aishaJuly 18, 2025

In Greek mythology, Theia was one of the Titans, the sister and later wife of Hyperion, and the mother of Selene, the goddess of the Moon. This mythological narrative interestingly parallels the scientific theory regarding the planet Theia’s role in the Moon’s formation. According to the giant impact hypothesis, Theia was a Mars-sized planetary body […]

Evidence and Search for Planet Nine: A Hypothetical Giant

noor-e-aishaJuly 16, 2025

In January 2016, astronomers Konstantin Batygin and Mike Brown from the California Institute of Technology (Caltech) announced research suggesting the existence of a planet about 1.5 times the size of Earth in the outer solar system. This theoretical world, dubbed “Planet Nine,” has not been directly observed, but its possible presence is inferred from the […]

Oort Cloud Explained: Distance, Formation, Structure, and Comet Origins

noor-e-aishaJuly 11, 2025

The Oort Cloud is the most distant region in our solar system, and it’s jaw-droppingly far away, extending perhaps one-quarter to halfway from our Sun to the next star.To appreciate the distance to the Oort Cloud, it’s helpful to set aside miles and kilometers and instead use the astronomical unit, or AU — a unit […]

What Is a Black Hole? Origins, Physics & Discovery Explained

noor-e-aishaJuly 11, 2025

A black hole is a massive, compact astronomical object so dense that its gravity prevents anything—even light—from escaping. Albert Einstein’s theory of general relativity predicts that a sufficiently compact mass will form a black hole. The boundary beyond which nothing can escape is called the event horizon. While a black hole has a profound effect […]

Full Moon Tonight: July 10, 2025 – Meaning, Color, and Visibility Explained

noor-e-aishaJuly 10, 2025

Today, July 10, 2025, the Moon is in its Full Moon phase, one of the most visually striking lunar phases. During this phase, the entire face of the Moon that faces Earth is fully illuminated by the Sun, making it appear as a complete, bright circle in the night sky. This occurs because the Earth […]

The Kuiper Belt: A Gateway to the Early Solar System

noor-e-aishaJuly 10, 2025

The name Kuiper is of Dutch origin and is an occupational surname meaning “cooper,” or barrel maker. In astronomy, however, the Kuiper Belt refers to a vast region of the outer solar system named after Dutch-American astronomer Gerard Kuiper, who theorized about the existence of such a zone, although he did not predict its current […]
