  1. The Magnetic Galaxy Far Far Away

    The Magnetic Galaxy Far Far Away
    Ever since the dawn of our species, humans have gazed up at the sky in wonder. What secrets do stars and moons and planets hold? What could they tell us about our own planet? What could they tell us about the universe at large? This general search for meaning is the driving force behind any of the sciences, astronomy notwithstanding. Continue reading →
  2. The Eclipse Helps Us Understand the Sun's Magnetic Field

    The Eclipse Helps Us Understand the Sun's Magnetic Field
    If you haven’t heard by now, there will be a total solar eclipse occurring Monday, August 21st. The Great American Eclipse will be viewable across the country at different times depending on your location. You can see a full map and times of full obscurity here. But what exactly happens during a full eclipse? Continue reading →
  3. The Erratic Magnetism on Uranus

    The Erratic Magnetism on Uranus
    One of the greatest things about our solar system is that every single planet is unique. From Saturn’s magnificent rings to sulfuric acid of Venus’s atmosphere to Earth’s ability to sustain life. In addition, some planets offer fascinating magnetism. Our own magnetic field keeps us safe from harmful radiation and creates stunning aurorae. Jupiter’s magnetic field is the largest single object in the entire solar system! Continue reading →
  4. Studying the Magnetic Fields of New Stars

    Studying the Magnetic Fields of New Stars
    Stars begin as clouds of gas in space. The gravitational collapse that will form the star begins because of the cold temperatures and high density of these clouds. Before reaching star status, this ball of gas’s core must be hot enough for the fusion that powers it to take place. Until then, it’s just a protostar. Continue reading →
  5. Magnetism is Key to Unearthing New Crater

    Magnetism is Key to Unearthing New Crater
    The Falklands, an archipelago off the coast of Argentina, are hiding a pretty big secret. Northwest of West Falkland Island and dating back to the late Paleozoic Era around the time of the extinction of more than 90% of life on the planet, an event known as The Great Dying or the Permian Extinction. Continue reading →
  6. Uncharted Territory on Two Wheels

    Uncharted Territory on Two Wheels
    Earth is pretty much mapped out, so you’d think there’s not much else left to do, right? Not exactly. Magnetic surveying is a geophysical method of mapping out the terrain, used both on land and in marine archaeology. These surveys detect spatial variations in the Earth’s magnetic field. Typically, this is accomplished on foot while carrying the necessary magnetic sensors in a backpack. Surveyors can usually cover between 10 and 12 kilometers (6.21-7.45 miles) per day. However, many surveyors get tuckered after 2-3 kilometers. Sounds time-consuming, right? Continue reading →
  7. Eels Have A Sense For Magnetic Fields

    Eels Have A Sense For Magnetic Fields
    When humans give birth, most of us go to a nearby hospital. Fish, however, migrate long distances, sometimes thousands of miles, to reproduce. Sounds crazy, right? Some fish are anadromous, traveling from the sea into freshwater and others are catadromous, moving from rivers into saltwater. Continue reading →
  8. There’s a New Kind of Aurora, and his Name is Steve

    There’s a New Kind of Aurora, and his Name is Steve
    One of the most beautiful phenomena on planet Earth has to be the aurora. Occurring near the planet’s north and south poles, the aurora borealis and aurora australis have been dazzling and mystifying human beings since antiquity. The aurora, brilliant bands of colorful light dancing across the sky, are the result of light particles from the sun meeting Earth’s magnetic field. The magnetic field is strongest near the poles, hence why this color show is typically only viewed at higher latitudes. Continue reading →
  9. The Moon Once Had Its Own Magnetic Field

    The Moon Once Had Its Own Magnetic Field
    Devotees of this blog surely know how much we love Earth’s magnetic field. Indeed, it’s a pretty important component for sustaining life on our planet, shielding us from the harmful radiation hurled out by the sun. Other planets have them, too. Jupiter’s magnetic field is the largest entity in our entire solar system! Continue reading →
  10. The Trappist Planets and Magnetic Fields

    The Trappist Planets and Magnetic Fields
    By now, you’ve probably heard the news that NASA has discovered not 1, not 2, but 7 “Earth-like” planets revolving around nearby dwarf star, Trappist-1. These planets are thought to be in the habitable zone and could maybe, one day, sustain human life. Continue reading →
