Moon Formation

In a cataclysmic event, a Mars-sized object named Theia collided with the early Earth, sending massive amounts of debris into orbit. This debris coalesced over time to form the Moon, which eventually became tidally locked to the Earth, stabilizing the planet’s axis and paving the way for the development of life. The Moon is comprised […]

Late Heavy Bombardment

Visual Craters of the Moon! In a period known as the Late Heavy Bombardment, the solar system experienced a intense barrage of asteroid and comet impacts, with many large objects striking the Earth and Moon. This event likely occurred as the giant planets Jupiter and Saturn migrated to their current orbits, sending smaller bodies into

Second Atmosphere: Carbon Dioxide & Nitrogen

Deep orange or reddish-brown atmosphere: The second atmosphere’s formation was crucial and occurred just before or alongside the formation of Earth’s oceans, which directly supported the evolution of organic molecules and prebiotic microenvironments. The second atmosphere began to develop around 4.5 to 4 billion years ago, as volcanic outgassing released gases trapped in the Earth’s

Big Bang Expansion

30 Phil, Chapter 1 Touchstone 1 of 80: Big Bang. Immediately following the state of the singularity, the universe entered a phase of rapid expansion and cooling, known as the Big Bang Expansion. This critical period signifies not an explosion in space but the very expansion of space itself, from an incomprehensibly dense point known

RNA World

Following the appearance of self-replicating molecules, the RNA world hypothesis suggests a period where RNA served both as genetic material and as a catalyst for chemical reactions. This phase emphasizes the central role of RNA in early life forms, prior to the evolution of DNA and proteins. The RNA world could be considered both a

Assembly of Protocells

Between the development of metabolic pathways and the formation of cellular membranes, there might have been a phase involving the assembly of protocells. These protocells, formed from self-assembled lipid molecules creating vesicles, could encapsulate nucleic acids and metabolic molecules, offering a primitive model for cell-like structures. Protocells represent a bridge between non-living chemical systems and

Cellular Membranes

The formation of cellular membranes represents a pivotal development in the pre-life world, enabling the creation of defined boundaries for primitive cells. These membranes, likely formed from simple lipid bilayers, provided a controlled environment for chemical reactions and played a critical role in the emergence of the first cell-like structures, distinguishing them from their surrounding

Brand New Constellations

The constellations we recognize today will be vastly different in a million years due to what astromers call “proper motion” of stars. This will transform our night sky, creating new constellations from stars that have shifted positions, presenting future astronomers with a completely new celestial map to study. Because of stellar motion, our current Star

Black Dwarf Sun

Over an incredibly long timescale, the Sun’s white dwarf remnant could cool enough to become a black dwarf, a theoretical stellar remnant that emits no light. Although speculative, theoretical models give us insight into the lifespan of the Sun as a white dwarf. After transitioning into a white dwarf, the Sun is expected to cool
