1. Introduction: Why Lunar Craters Matter The Moon’s surface is covered with countless craters formed by asteroid and meteorite impacts over billions of years. Unlike Earth, the Moon lacks an atmosphere, weather and active plate tectonics so these craters remain preserved for extremely long periods. Because of this preservation, lunar craters act like time machines…
While it looks like a perfect silver coin in the night sky, the Moon is technically an oblate spheroid—a sphere that is slightly flattened at the poles and bulged at the center. However, planetary scientists often go a step further and describe it as lemon-shaped because it has two distinct bulges: one on the side…
It may like a plot from a sci-fi movie, but the Moon is indeed drifting away from Earth. This phenomenon is known as Lunar Recession, and it has been occurring since the Moon first formed about 4.5 billion years ago. Here is the full breakdown of how it works, how we know, and what the…
1. What Is Gravitational Relationship Gravitation is a mutual attractive force between any two masses in the universe. According to Newton’s Law of Universal Gravitation: F = G(m1*m2/r^2) Where: More mass = Stronger gravityMore distance = Weaker gravity 2. The Three-Body System: Sun–Earth–Moon The Sun, Earth and Moon form a gravitationally bound three-body system where…
Standing on the surface of Mars at dusk offers a surreal reversal of the Earthly experience. While we are used to a blue sky during the day that bleeds into a fiery red and orange sunset, Mars does the exact opposite. On the Red Planet, the daytime sky is a murky butterscotch color, but as…
In space, the biological process of crying remains the same, but the physical behavior of the liquid changes dramatically. On Earth, gravity pulls tears down your cheeks; in the microgravity of the International Space Station (ISS), physics takes over in a much messier way. Here is the full breakdown of what happens when you cry…
Although the Moon appears calm and simple from Earth, its interior hides a complex and fascinating structure shaped by ancient cosmic events. Scientists have uncovered the Moon’s internal layers using seismic data from Apollo missions, lunar rock samples, gravity measurements and modern spacecraft observations. The Moon’s anatomy reveals clues about its violent origin, thermal history…
Time Dilation: Why Time Moves Slower in Space The idea that “Time Moves Slower in Space” is not science fiction; it is a validated consequence of Albert Einstein’s theories of Relativity. This phenomenon is called Time Dilation, and it means that time is not absolute—it passes differently for observers depending on their relative speed and…
Auroras—often called the Northern and Southern Lights—are among the most breathtaking natural displays on Earth. Shimmering curtains of green, red, purple, and blue light ripple across polar skies, appearing calm and magical. But behind this beauty lies a story of solar violence, charged particles, and powerful space weather driven by the Sun. The Sun: A…
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…
