  1. Space Sustainability: Using Magnets to Clean Up Dead Satellites

    Space Sustainability: Using Magnets to Clean Up Dead Satellites
    We’re all pretty familiar with the importance of sustainability. Picking up trash, recycling, reusing when possible, and decreasing our carbon footprint are all important ways to keep Earth’s environment balanced and healthy. What about beyond Earth’s surface though? Well, scientists have been developing a new form of environmentalism —space sustainability, and magnets are leading the new technology designed to clean up debris and dead satellites in space.  Learn how magnets can keep our outer environment as sustainable as our interior one.  Continue reading →
  2. Geomagnetic Jerks

    Geomagnetic Jerks
    At Apex, we cover all types of magnetic news and discoveries from the Moon’s magnetism to aquatic robots activated by magnets. But there’s one phenomenon we haven't been able to fully understand and talk about—until now — geomagnetic jerks. In a recent blog, we discussed how there’s a “dent” in Earth’s magnetic field, called the South Atlantic Anomaly, which is essentially a weak spot in the magnetic field. The radiation caused by this anomaly poses a threat to our satellites and their onboard computers while moving through this spot —but, it’s not the only strange occurrence resulting from the magnetic field. Enter the jerks— geomagnetic jerks, that is. These are abrupt changes in the strength of Earth's magnetic field, resulting in pulses that, like the anomaly, can compromise our satellites.  Continue reading →
  3. Two Things You May Not Know About Earth’s Magnetic Field

    Two Things You May Not Know About Earth’s Magnetic Field
    If you didn’t know already, the Earth is a giant magnet. Its magnetic field comes from its core being solid iron, with molten metal surrounding it. This magnetic field acts like a protective shield around the planet, trapping and repelling charged particles from the Sun. There’s a lot to learn about Earth’s magnetic field, with new discoveries being made almost yearly! In this blog post we’re covering two things — the “dent” in the magnetic field, and how the field flips.  Continue reading →
  4. The Long Relationship Between the Moon and Magnetism

    The Long Relationship Between the Moon and Magnetism
    While the moon doesn’t have its own magnetic field—anymore—the moon and magnetism do go hand in hand. From meteors, plasmas, and the moon being part of Earth once, there have been a lot of discoveries in terms of the moon and magnetism! Here, we’re rounding up the articles we’ve written on the topic.  Continue reading →
  5. What’s Going on In Space: Magnetism Edition

    What’s Going on In Space: Magnetism Edition
    What do a cat’s paw, a whirlpool, and a cigar have to do with each other? We’re glad you asked. Just as cloud-watching will show you figures and outlines of people, animals, and objects, outer space is no exception. In fact, a cat’s paw, a whirlpool, and a cigar are just the latest shapes of nebulas and galaxies that are currently being studied by astronomers for their magnetic fields. Read on to hear more about the latest interesting shapes that are forming in space.  Continue reading →
  6. Jellyfish Galaxies and Their Magnetic Fields

    Jellyfish Galaxies and Their Magnetic Fields
    While we know that the magnetic fields in galaxies can contribute to star formation, one type of galaxy has left scientists questioning this fact. So called “jellyfish galaxies' ' fall into the center of a galaxy cluster, which get their name from their jellyfish-like tails. It’s been theorized that the rarified gas of jellyfish tails can also form stars, but research hasn’t been able to confirm this as these galaxies are difficult to study due to their low brightness. That is until now.  Continue reading →
  7. Our Solar System’s Magnetic Bubble Resembles an Interesting Food

    Our Solar System’s Magnetic Bubble Resembles an Interesting Food
    All of the planets in the solar system are encased in a magnetic bubble. For years, scientists tried to figure out what this bubble looked like, but it’s been hard to measure because the closest point is more than ten billion miles from Earth. By using a model developed with data from NASA missions, scientists have developed a new prediction of the shape of the bubble surrounding our solar system —  and you might be just as surprised as they were to find it looks a lot like a croissant.  Continue reading →
  8. An Explanation for Why Solar Winds Are Hotter Than Expected

    An Explanation for Why Solar Winds Are Hotter Than Expected
    The topic of solar wind has been discussed since it’s discovery in 1959, but, there’s still a lot that we don’t know about it. One of solar winds’ mysteries surrounds the fact that when it reaches the Earth, satellite measurements are recording temperatures that are hotter than the laws of physics would predict. Physicists from the University of Wisconsin - Madison may now know the reason why this is with their study that was published April 14 in the Proceedings of the National Academy of Sciences.

  9. Using Magnets to Collect Martian Dust

    Using Magnets to Collect Martian Dust
    Space exploration may still seem like science fiction to some, but rest assured, it is very real, and humanity is learning more each year. Our scientists are actually starting to get down to the nitty-gritty of space, meaning Martian rocks and dust. This highly magnetic material is collected by exploratory rovers so that we can study and reveal any secrets it might hold about Mars’ past, specifically in relation to geologic history.  Continue reading →
  10. NASA Detects Ancient Magnetism on Surface of Mars

    NASA Detects Ancient Magnetism on Surface of Mars
    Learning more about Mars has been one of NASA’s top priorities over the last several years. One of their newest discoveries, thanks to NASA’s InSight Lander, indicates that Mars’ magnetism is much stronger than previously anticipated.  Continue reading →
