Around 4.5 billion years ago, the early solar system was a violent, chaotic place filled with newborn planets, drifting debris and colossal collisions. One such event, often described as a cosmic accident, reshaped Earth permanently and set the stage for life as we know it. The Catastrophic Collision Scientists believe a Mars-sized protoplanet, commonly called…
NASA’s Parker Solar Probe has made history by becoming the first spacecraft to fly directly through the Sun’s outer atmosphere, known as the corona. Launched in August 2018, the mission was designed to solve long-standing mysteries about the Sun by getting closer than any spacecraft before it. During its closest approaches, Parker traveled to within…
1. What the “Shifting Smile” Means The “Shifting Smile” refers to the changing shape of the Moon that we see from Earth — the phases of the Moon. Sometimes it looks like a thin crescent, sometimes a half-circle and sometimes full. This smile is not because the Moon changes shape but because the sunlight hitting…
1. NASA Prepares for Humanity’s Return to the Moon NASA’s Artemis initiative is rapidly shaping up to become the most ambitious human spaceflight program since Apollo. Building on decades of research, new commercial partnerships and evolving international cooperation. Artemis aims not just to visit the Moon but to stay. The program is targeting the lunar…
1. What Is the Solar Wind? The solar wind is a continuous stream of charged particles (mostly electrons + protons) that flow outward from the Sun in all directions. Key facts: The Sun’s intense heat gives particles enough energy to escape the Sun’s gravity → causing a constant outward “wind”. 2. Why Does the Solar…
At first glance, Moon dust may seem harmless just fine gray soil covering the lunar surface. But scientists and astronauts now agree on one thing: Moon dust (called lunar regolith) is one of the most dangerous hidden threats to future space exploration. It damages equipment, harms human lungs and could even limit long-term stays on…
The Sun, often seen as a steady source of light and warmth, is also a powerful engine of violent eruptions. Among its most dangerous outbursts are solar flares and coronal mass ejections (CMEs) two space phenomena that can directly impact satellites, power grids, communication systems and even internet connectivity on Earth. Although these events often…
Why Scientists Never Expected Water on the Moon For most of the 20th century, scientists believed the Moon was: Because of this: Even during the Apollo missions (1969–1972): This belief stayed unchanged until advanced space instruments became available. The Key Discovery: Permanently Shadowed Craters At the Moon’s north and south poles, there are deep craters…
The Earth–Moon–Sun System A perfectly balanced cosmic dance controlled by gravity and motion. The Earth–Moon–Sun system is a gravitational system where three celestial bodies move in a perfectly balanced pattern. The Earth revolves around the Sun once every 365.25 days and rotates on its axis every 24 hours, creating day and night. The Moon revolves…
What Exactly Is Kamoʻoalewa Kamoʻoalewa is a small, rocky object classified as a quasi-satellite. This means it does not orbit Earth like our Moon does. Instead, it orbits the Sun, but in such a way that it stays close to Earth and appears to loop around us. Its size is very small — around 40–60…
