Lunistices Though the sky is filled with immeasurable objects – galaxies, stars, asteroids, Uranus – two of them dominate our perspectives: the Sun and the Moon. Most celestial bodies feature tangible but often imperceptible cycles, thanks to Earth’s rotation, but our star and our satellite grace us with significant patterns. Our definitions of time and […]
The Anatomy of a Lunar Eclipse One of the English language’s most sublime words is syzygy. A syzygy occurs when at least three celestial bodies align in a plane. Note: the following images are not to scale! When we think of syzygies, we often think of the Earth, Sun, and Moon, but any three bodies could

Schrödinger’s Grand Canyons of the Moon Erwin Schrödinger is best known to the modern layperson for his eponymous, feline thought experiment. Schrödinger’s cat was designed during a conversation he had with Albert Einstein, about potential paradoxes that arise with certain interpretations of quantum mechanics. Inside a box is a kitty, a vial of poison, a radioactive

The First Untethered Spacewalk On 20 February 1984, astronaut Hoot Gibson peered out of Challenger at something rare and sensational. He grabbed a camera, took a light meter reading three times, checked the focus four times, and snapped one of the starkest, most indelible images in the history of photography.Bruce McCandless II floated 300 feet away, blanketed

Uranus Is Cold Really cold. You should probably get that checked out. The amount of light a body receives plummets exponentially as the distance to a star increases (the formula is 1/distance squared). Uranus is just over 19 astronomical units away from the Sun, meaning it gets 0.27% of the sunlight we receive on Earth
Parade of Planets Gazing into the night sky can impart a viewer with a sobering sense of perspective. The billions of stars out there. The millions of years the light took to travel from distant galaxies. It’s easy to be overwhelmed with a feeling of unimportance, as if we’re a speck of sand on a
The Carrington Event It was a sight never to be forgotten, and was considered at the time to be the greatest aurora recorded […]. The rationalist and pantheist saw nature in her most exquisite robes, recognising, the divine immanence, immutable law, cause, and effect. The superstitious and the fanatical had dire forebodings, and thought it

Sunspots, Solar Flares, & CMEs In Part I of this series, we discovered the Sun emits more than just visible light. The outermost portion of the Sun – the corona – becomes so hot that particles gather enough kinetic energy to escape the star’s gravity. As these masses flee the Sun, they become the solar wind, moving

Sunlight & Solar Wind Stars are the gnarly dynamos of the largely empty universe. Packed with nuclear reactors at their cores, these bodies make life possible. The number of factors that allow Earth to teem with life is high enough to make one believe in serendipity. We owe everything to our star – the Sun

The Great North American Eclipse Preview Perhaps the most anticipated natural or scientific event to occur since the advent of this project will cast shadows on Earth on 8 April 2024. Dubbed the Great North American Eclipse by many, on the afternoon of the second Monday in April, the moon will move between the sun and the
