  1. Black Holes and Their Coronal Magnetic Field

    Black Holes and Their Coronal Magnetic Field
      Did you know that supermassive black holes are the largest type of black hole known to mankind? In fact, they contain a mass that is more than a billion times larger than typical black holes. It has been discovered that the supermassive black holes that lurk at the center of most galaxies are surrounded by coronas, but not much is known about why this occurs or even what coronas look like.

  2. Magnetic Field Causes Metamaterial to Stiffen

    Magnetic Field Causes Metamaterial to Stiffen
    A new synthetic material has been shown to have interchangeable stiffness when it comes in contact with magnets. This metamaterial—an artificial structure comprised of a grid-like network of plastic tubes filled with fluid that becomes more viscous in a magnetic field—causes the tubes to firm up in a magnetic field, allowing the tube to turn from soft to rigid in a split second.

  3. Unveiling Complexity in Jupiter’s Magnetic Equator

    Unveiling Complexity in Jupiter’s Magnetic Equator
    There’s more to Jupiter than what meets the eye. At least, that’s what planetary scientists recently discovered when they stumbled upon a mysterious dark “ribbon” around Jupiter’s magnetic equator. This ribbon, created by interactions between the planet’s magnetic field and ionosphere, was found by a team led by University of Leicester planetary astronomer Tom Stallard. Continue reading →
  4. The Human Magnetic Field: Is It Real?

    The Human Magnetic Field: Is It Real?
    You’ve heard the phrase “magnetic personalities” before, but are there actually magnetic people? You’ve probably seen videos circulating on the internet of people claiming to be magnetic. They place objects on their bodies only for them to hold their place rather than fall to the ground as one would expect. Are these “magnetic people” truly magnetic? Continue reading →
  5. Hawaii Volcano Has Weird Magnetic Field

    Hawaii Volcano Has Weird Magnetic Field
    We’re not using “magnetism” in the metaphorical sense, the Hawaii volcano Kilauea is doing something pretty strange. Over the past month, the extremely active shield volcano has caused countless damage on Hawaii’s largest island of the same name. Continue reading →
  6. Saturn's Poles Produce Their Own Auroras

    Saturn's Poles Produce Their Own Auroras
    If you haven’t seen the Earth’s aurora borealis in person, you’ve seen pictures – majestic colors that light up the night sky. Planet Earth has so many unique features, like our surface water and abundance of constantly evolving life. But the lights of an aurora? We aren’t the only planet that can boast about them. Did you know that Saturn also produces the phenomenon? However, there’s something different about them. But before we get into that, how does this kind of light show occur in the first place? Here’s a clue: it involves magnets. Continue reading →
  7. Earth’s Magnetic Field is Actually a Solar-Wind Shredder

    Earth’s Magnetic Field is Actually a Solar-Wind Shredder
    At one point in time, Mars – arguably the most similar planet to Earth in our solar system –  wasn’t the frozen desert we know today. In fact, researchers suggest that oceans and rivers once existed on its surface before solar winds from the Sun completely wiped them out. Continue reading →
  8. Did You Know That the Sun's Heliosphere is Actually a Magnetic Solar Bubble?

    Did You Know That the Sun's Heliosphere is Actually a Magnetic Solar Bubble?
    In its essence, the Sun is considered the heart of our solar system. From Earth’s standpoint, the scorching yellow star of glowing gases directly dictates its seasons, ocean currents, climates and aurorae. If the sun were the size of a front door, Earth would be about the size of a nickel. And without its energy, human life wouldn’t even exist. Crazy to consider, right? However, that example only provides a slight sliver of the Sun’s impact. In actuality, it holds the entire galaxy in place, keeping everything from the largest of planets  – Jupiter, Saturn, and Uranus – to the smallest particles of debris in orbit within a magnetic field called the heliosphere that stretches 23 billion miles.

  9. Mars' Missing Magnetic Field

    Mars' Missing Magnetic Field
    Mars may just be the best magician yet. We know that Mars doesn’t possess a magnetic field comparable to Earth’s, but scientists have been researching for years to determine what caused the magnetic field’s’ disappearance. A recent study may have given us insight on how Mars’ magnetic field vanished over four billion years ago. But there’s a plot twist: this theory includes self-sabotage. Continue reading →
  10. Oceanic Magnetism and Earth's Magnetic Field

    Oceanic Magnetism and Earth's Magnetic Field
    The ocean is a terrifying place (exhibit A), but it sure is fascinating. With so many mysteries hidden in its depths, it’s sometimes surprising that we know anything about this mass that covers 71% of our planet. For instance, have you ever heard of oceanic magnetism? Well, read on! Continue reading →
