  • Is Earth's core lopsided? Strange goings-on in our planet's interior

    Phys.org ^ | June 3. 2021
    The faster growth under Indonesia's Banda Sea hasn't left the core lopsided. Gravity evenly distributes the new growth—iron crystals that form as the molten iron cools—to maintain a spherical inner core that grows in radius by an average of 1 millimeter per year. But the enhanced growth on one side suggests that something in Earth's outer core or mantle under Indonesia is removing heat from the inner core at a faster rate than on the opposite side, under Brazil. Quicker cooling on one side would accelerate iron crystallization and inner core growth on that side. This has implications for Earth's...

    A peculiar ranch incident in New Mexico nearly 75 years ago has kept UFO enthusiasts intrigued at the possible presence of alien life on Earth until this very day.ROSWELL, N.M. — A peculiar ranch incident near Roswell, New Mexico nearly 75 years ago still intrigues UFO enthusiasts about the possible presence of extra-terrestrial life on Earth. Amid a violent summer thunderstorm in July 1947, a large flying object fell out of favor with the gods and crashed on a ranch about 75 miles northwest of the military town. The events to follow gave rise to Roswell as a tourist attraction...
  • Water world: Entire Earth was covered in a global ocean three billion years ago that would have submerged Mount Everest

    A new analysis suggests Earth may have been a water world three to four billion years ago with a global ocean large enough to have submerged Mount Everest. Scientists at Harvard University examined our planet's ancient mantle and found that in ages past it was four times hotter due to radioactivity, and would therefore not be able to hold the current amount of water. 'We find that water storage capacity in a hot, early mantle may have been smaller than the amount of water Earth's mantle currently holds, so the additional water in the mantle today would have resided on...

    A strange dent in Earth’s magnetic field doses orbiting craft with high levels of radiation. It's caused everything from periodic glitches to total mission failure. The European Space Agency’s Swarm satellites measure the strength of Earth’s magnetic field. In this image, cooler colors (blue) mean lower strength than warmer colors (pink). The large dark region is called the South Atlantic Anomaly Radiation is a colorless, tasteless, and odorless enemy to both humans and electronics alike. And, thanks to a quirk in Earth’s magnetic field, a region called the South Atlantic Anomaly (SAA) regularly exposes orbiting spacecraft to high levels of...
  • Earth is at perihelion — closer to the sun than on any other day of the year

    Although sunlight is more intense on Saturday, winter in the Northern Hemisphere is unaffected, due to the 23.5-degree tilt of Earth's axis. Being closer to the sun does not change the Earth's tilt, so the North Pole is still tilted away from the sun. Six months from now, on July 5, Earth will be at its farthest from the sun, known as its aphelion, meaning "far from the sun." At perihelion, Earth is about 91.5 million miles from the sun, and at aphelion, it is around 94.5 million miles away. Between perihelion and aphelion, there is about a 6.7% difference...

    As if we didn’t have enough reasons to hate 2020, the United Nations just offered one more. On Wednesday, the U.N. and the World Meteorological organization released a report on the “state of the climate” and – surprise, surprise – it looks bleak. The year from hell is on course to be the third warmest on record, viruses are jumping out of nature to attack us, and the world has already warmed 1.2 degrees Celsius since pre-industrial times. “To put it simply, the state of the planet is broken,” said U.N. Secretary-General António Guterres, in a speech at Columbia University....

    Earth Is a Whole Lot Closer to Our Galaxy's Supermassive Black Hole Than We Thought MICHELLE STARR 27 NOVEMBER 2020 It seems that Earth has been misplaced. According to a new map of the Milky Way galaxy, the Solar System's position isn't where we thought it was. Not only is it closer to the galactic centre - and the supermassive hole therein, Sagittarius A* - it's orbiting at a faster clip. It's nothing to be concerned about; we're not actually moving closer to Sgr A*, and we're in no danger of being slurped up. Rather, our map of the Milky...

    Why is Earth pulsating every 26 seconds, and why canÂ’t scientists explain it after 60 years? This is an enigma wrapped in a periodically predictable mystery motion. It could be a harmonic phenomenon, a regular seismic chirp caused by the sunÂ’s energy, or a beacon drawing scientists to its source to begin a treasure hunt. âž¡ The world is weird. We'll show you how it works. In the early 1960s, a geologist named Jack Oliver first documented the pulse, also known as a "microseism," according to Discover. Oliver, who worked at Columbia University's Lamont-Doherty Geological Observatory at the time, heard...

    Set your alarm for two hours before sunrise to catch the best view of Jupiter sinking in the southwestern sky with Saturn just above and to the right, according to Travel and Leisure magazine. Trace a curved line through both planets into the southern sky and you'll hit Mars high above the southeastern horizon. To see Venus and Mercury, trace Mars' curve down to the horizon in the northeast. Before you get there, you'll easily spot Venus, one of the brightest objects in the night sky. Also, be sure to pencil in a special date between these five planets. Just...

    Explanation: What are those dots between Saturn's rings? Our Earth and Moon. Just over three years ago, because the Sun was temporarily blocked by the body of Saturn, the robotic Cassini spacecraft was able to look toward the inner Solar System. There, it spotted our Earth and Moon -- just pin-pricks of light lying about 1.4 billion kilometers distant. Toward the right of the featured image is Saturn's A ring, with the broad Encke Gap on the far right and the narrower Keeler Gap toward the center. On the far left is Saturn's continually changing F Ring. From this perspective,...

    The only thing more certain than death is that if a liberal accuses a conservative of doing something, you can be sure the liberal is doing it. For decades, conservatives have been portrayed as anti-environment knuckle-draggers that want to poison the planet because they care more about green money than a green earth. The new documentary, Planet of the Humans, produced by flaming liberal Michael Moore, provides ample evidence it's the left that's been raping planet earth all along.

    Some 90 million years ago, a temperate rainforest grew near the South Pole. Scientists recovered fossil traces of the ancient rainforest from seafloor sediment cores collected near West Antarctica's Pine Island Glacier. Seismic data suggested the sediment layer was unique, but researchers weren't expecting to find the remnants of a Cretaceous forest. "The finding of this well preserved 'forest soil' layer was actually a lucky dip," researcher Ulrich Salzmann, professor of palaeoecology at the University of Northumbria in Britain, told UPI. "We did not know of the existence of this layer before." Among the sediment layers, Salzmann and his research...

    According to the provided article, asteroid 99942 Apophis has a 1 in 40 chance of hitting earth in 2029. If it misses in 2029, it would have an even higher chance of hitting in 2036. According to NASA and other reputable sources the asteroid is of 370 meters in diameter which is about the size of the Eiffel Tower. When you plug this into a simulation like the asteroid collision map, you can see that its large magnitude can cause some pretty serious damages depending on the location it impacts. According to the simulation, some of these effects are earthquakes,...

    Sunspot activity on the surface of the Sun follows a well-known but little understood 11 year cycle. Activity rises and falls creating the so-called solar maximum and then solar minimum. During a solar maximum, the Sun is more powerful and is littered with sunspots. Conversely when the Sun enters a solar minimum – which it did about two years ago - energy from our host star begins to lessen. However, one expert has warned that the Sun will enter a period of “hibernation” this year, in what as known as a Grand Solar Minimum (GSM). **SNIP** “The reduction in temperature...
