    Swarm Probes Weakening Of Earth's Magnetic Field

    Published 20th May 2020



    In an area stretching from Africa to South America, Earth's magnetic field is gradually weakening. This strange behaviour has geophysicists puzzled and is causing technical disturbances in satellites orbiting Earth. Scientists are using data from ESA's Swarm constellation to improve our understanding of this area known as the 'South Atlantic Anomaly.'

    Earth's magnetic field is vital to life on our planet. It is a complex and dynamic force that protects us from cosmic radiation and charged particles from the Sun. The magnetic field is largely generated by an ocean of superheated, swirling liquid iron that makes up the outer core around 3000 km beneath our feet. Acting as a spinning conductor in a bicycle dynamo, it creates electrical currents, which in turn, generate our continuously changing electromagnetic field.

    New Understanding Of Deep Earthquakes

    Published 27th May 2020

    Earthquakes that occur more than 300 kilometers below the Earth are poorly understood. UC Davis geophysicist Magali Billen modeled stresses in a sinking tectonic plate at a subduction zone. In this video, yellow regions on the sinking plate show where deep earthquakes are most likely to occur, because the plate is both strong and deforming rapidly. This work can explain why earthquakes cluster at certain depths and lead to a better understanding of the causes of deep earthquakes.

    Red Sprites & Blue Jets Explained

    Published 26th May 2020

    Science of how red sprites and blue jets form over thunderstorms. Some of the greatest red sprites ever caught on camera with easy to understand explanations including a new discovery are highlighted in this video. Explore the colorful world of Transient Luminous Events including gigantic jets, elves, halos and more as they are initiated by massive horizontally extensive lightning flashes in thunderstorms far below.

    On rare nights with clear visibility over powerful distant thunderstorms, you might be able to see and capture red sprites. Sprites are large scale electrical discharges occurring high above thunderstorms in the upper atmosphere. They are massive events, sometimes 50 kilometers tall by 50 kilometers wide. Sprites belong to a mysterious and colorful group of phenomenon called Transient Luminous Events, or TLEs. Other TLE’s include halos, Elves, trolls, secondary jets, Blue starters, Blue jets and the magnificent gigantic jets. But what exactly are these transient luminous Events, and how do they form?

    In 2019 Hank teamed up with one of the most successful TLE photographers in the world, Paul Smith. Our objective was to simultaneously document TLEs from different locations to help US understand and CAPTURE them better. We didn’t know what we would find, if anything… But we never expected to DISCOVER a NEW TLE.

    RED SPRITE DISCOVERY
    Visual reports of Transient Luminous Events date back several centuries.
    It wasn’t until 1989 that the first ones were accidentally caught on camera.
    Years after discovery, they were named sprites for their spirit like nature.

    BASIC PHYSICS:
    In Hank's last video we showed how one lightning flash can abruptly change the electric field triggering a second lightning flash in a sort of domino effect. Sprites are also initiated by a large electric field change that occurs during a massive horizontally extensive lightning strike far below. These parent flashes transfer huge amounts of charge and are almost always positive in polarity… Meaning that the earth rapidly gains a net positive charge from the strike. But pools of positive charge near the tops of thunderstorm complexes also change, abruptly gaining negative charge.
    This suddenly creates a powerful electric field between the tops of thunderstorms and a high concentration of positively charged ions existing 100 kilometers or so up into the lower ionosphere. It’s this new imbalance that can initiate a sprite.

    BLUE JETS:
    On occasion, a cloud flash will have one end of the leader exit the upper extent of the thunderstorm and propagate toward the upper atmosphere. The rarified air and low pressure of the upper atmosphere leads to a visible transformation in the leader as the ionization travels upward. This is how a blue jet forms, as well as gigantic jets.

    SECONDARY JETS:
    Sometimes a large sprite event can trigger a second TLE. We call these secondary jets. Secondary jets become visible near the tops of thunderstorms where Nitrogen excites in the blues or purples and extend upward to altitudes where Nitrogen excites more red. In a photograph of a sprite and secondary jet event, you can see the gradual transitioning from blues to reds as the pressure quickly decreases in altitude.

    NEW TLE DISCOVERY
    On May 25, 2019 Hank was documenting a vibrant sprite storm over Oklahoma and captured something Hank had never seen or heard of. After two large sprite events, a mysterious green afterglow appeared. It seemed as if the sprite had triggered a small Aurora. Early that next morning Hank called Paul to discuss the strange captures. He was the first to agree it was something new and hypothesized that it was likely oxygen being excited by powerful sprites. Keeping in the theme of sprites, trolls and elves, we are referring to these Green emissions from excited Oxygen in Sprite Tops as GhOSTs.

    Dinosaur-Dooming Asteroid Struck Earth @ 'Deadliest Possible' Angle

    Published 26th May 2020



    New simulations from Imperial College London have revealed the asteroid that doomed the dinosaurs struck Earth at the 'deadliest possible' angle.
    The simulations show that the asteroid hit Earth at an angle of about 60 degrees, which maximised the amount of climate-changing gases thrust into the upper atmosphere.
    Such a strike likely unleashed billions of tonnes of sulphur, blocking the sun and triggering the nuclear winter that killed the dinosaurs and 75 per cent of life on Earth 66 million years ago.
    Drawn from a combination of 3-D numerical impact simulations and geophysical data from the site of the impact, the new models are the first ever fully 3-D simulations to reproduce the whole event—from the initial impact to the moment the final crater, now known as Chicxulub, was formed.

    The 'Cow' Mystery Strikes Back: Two More Rare, Explosive Events Captured

    Published 26th May 2020



    The 'Cow' is not alone; with the help of W. M. Keck Observatory on Maunakea in Hawaii, astronomers have discovered two more like it—the 'Koala' and a similar mysterious bright object called CSS161010. This trio of fast blue optical transients (FBOTs) appear to be relatives, all belonging to a highly-luminous family that has a track record for surprising astronomers with their fast, powerful bursts of energy.

    The 'Koala,' which is a nickname derived from the tail end of its official name ZTF18abvkwla, suddenly appeared as a bright new source in the optical sky before disappearing within just a few nights. A team of astronomers at Caltech realized this behavior was similar to the 'Cow' and requested radio observations to see if the two were connected.

    Study Unveils Properties Of Eleven Recently Discovered Pulsars

    Published 26th May 2020



    An international team of astronomers has conducted a detailed study of 11 pulsars recently discovered by the Five-hundred-meter Aperture Spherical radio Telescope (FAST). The new research, presented in a paper published May 19 on arXiv.org, delivers essential information about the properties of these objects.

    Pulsars are highly magnetized, rotating neutron stars emitting a beam of electromagnetic radiation. They are usually detected in the form of short bursts of radio emission, however some of them are also observed using optical, X-ray and gamma-ray telescopes. To date, most pulsars have been discovered using the Parkes Observatory in Australia.

    Astronomers Create Cloud Atlas For Hot, Jupiter-like Exoplanets

    Published 27th May 2020



    Giant planets in our solar system and circling other stars have exotic clouds unlike anything on Earth, and the gas giants orbiting close to their stars — so-called hot Jupiters — boast the most extreme.

    A team of astronomers from the United States, Canada and the United Kingdom have now come up with a model that predicts which of the many types of proposed clouds, from sapphire to smoggy methane haze, to expect on hot Jupiters of different temperatures, up to thousands of degrees Kelvin.

    Surprisingly, the most common type of cloud, expected over a large range of temperatures, should consist of liquid or solid droplets of silicon and oxygen, like melted quartz or molten sand. On cooler hot Jupiters, below about 950 Kelvin (1,250 degrees Fahrenheit), skies are dominated by a hydrocarbon haze, essentially smog.

    David Halperin | The Hidden Story Of The UFO

    Streamed & Published 26th May 2020



    First we have guest/listener Jacques from Canada to discuss an incredible childhood encounter, then featured guest, UFO Skeptic David Halperin to discuss his latest book; INTIMATE ALIEN: THE HIDDEN STORY OF THE UFO, David believes what we see in a manifest from within.

    BIO: Back in the 1960s, David Halperin was a teenage UFO investigator. Later he became a professor of religious studies — his specialty, religious traditions of heavenly ascent. From 1976 through 2000, David taught Jewish history in the Religious Studies Department at the University of North Carolina, Chapel Hill.

    Now retired from teaching, he lives in North Carolina with his wife Rose. He’s the author of five non-fiction books on Jewish mysticism and messianism, the coming-of-age novel Journal of a UFO Investigator, and now Intimate Alien: The Hidden Story of the UFO.

    For a more academically oriented bio, reflecting David’s work as a Judaica scholar, visit his author page on Liverpool University Press.

    Fermi Paradox: The Vastness Of Space

    Published 27th May 2020

    Today, we discuss solutions to the Fermi paradox involving the hard and irrefutable fact that space is simply too vast to conquer. Despite there being the possibility of thousands of technologically advanced civilisations distributed across the entire Galaxy, it may be that interstellar distances prevent not only the feasibility of interstellar travel but also of interstellar communication. Is this why we aren’t seeing the Galaxy swarming with life?

    Pulsar Mapped For The First Time

    Published 27th May 2020

    For the first time ever, the surface of a pulsar has been mapped using NASA's NICER X-ray telescope. NASA's Neutron star Interior Composition Explorer (NICER) made the first surface map of the pulsar PSR J0030+0451, a millisecond pulsar located 1100 light-years away in the constellation Pisces. But the surface maps don't look like the traditional magnetic dipole model we're used to. Instead, two - or three - X-ray hotspots were all found in the pulsar's south polar region!

    Does Gravity Require Extra Dimensions?

    Published 27th May 2020

    It’s been 120 years since Henry Cavendish measured the gravitational constant with a pair of lead balls suspended by a wire. The fundamental nature of gravity still eludes our best minds - but those secrets may be revealed by turning back to the Cavendish experiment. That steampunk contraption may even reveal the existence of extra dimensions of space.

    THIS ASTROPHYSICIST 'SEES' THE UNIVERSE IN THE MOST AMAZING WAY
    (5:19 min.)
    "Each celestial body, in fact each and every atom, produces a particular sound on account of its movement, its rhythm or vibration. All these sounds and vibrations form a universal harmony in which each element, while having it’s own function and character, contributes to the whole."
    - Pythagoras, ancient Greek metaphysician
    'Wanda Diaz-Merced studies the universe through sound. After losing her eyesight in early adulthood, she found a way to continue her work as an astrophysicist by converting scientific data into sound.

    Through a process known as "sonification," Diaz-Merced listens to the stars to detect patterns in seemingly random astrophysical data. As she says, “If we only see with our eyes, our perception is very narrow.”

    In this short from Emic Films, blind astrophysicist Wanda Diaz-Merced explains her passion for listening to the music of the cosmos.'

    "Your planet is forbidden for an open visit - extremely aggressive social environment,despite almost perfect climatic conditions.Almost 4 billion violent deaths for the last 5000 years and about 15000 major military conflicts in the same period."

    Space News | Does Gravity Make Light Bulbs Glow?

    Published 29th May 2020

    One of the strangest cosmic phenomena ever observed in the Milky Way galaxy is the Fermi Bubbles. In 2010, astronomers using the Fermi Gamma-ray Space Telescope discovered the so-called bubbles — giant structures, mostly composed of gamma-rays, that stretch for tens of thousands of lightyears above and below the Milky Way’s spiral disk.

    The so-called bubbles' incredible size and weird energetic emissions have been a source of ongoing puzzlement for the last decade. However, plasma physicists can easily see the bubbles as demonstrations of electrical phenomenon documented in laboratories over many decades.
