New data reveals Earth closer to a black hole and 16,000 mph faster

A new study shows our planet is much closer to the supermassive black hole at the galaxy's center than previously estimated.

  • A Japanese radio astronomy project revealed Earth is 2,000 light years closer to the supermassive black hole at the Milky Way's center.
  • The data also showed the planet is moving 7 km/s or 16,000 mph faster in orbit around the Galactic Center.
  • The findings don't mean Earth is in more danger from the black hole but reflect better modeling of the galaxy.

    • A new study finds similarities between the structures and processes of the human brain and the cosmic web.
    • The research was carried out by an astrophysicist and a neurosurgeon.
    • The two systems are vastly different in size but resemble each other in several key areas.

    • Scientists use artificial intelligence to reconstruct the globular clusters that merged to form our Milky Way galaxy.
    • The researchers ran simulations on a neural network to discover the history and details about our galactic ancestors.
    • They found that a collision with a previous galaxy called "Kraken" was so powerful it transformed the Milky Way.

    • Flat-Earthers drive rational people nuts.
    • A physicist offers three experiments to confirm it is those people who are crazy, not you.
    • The experiments, however, do require a belief in mathematics.

    Scientists may have solved the mystery of how the moon was magnetized

    New research explains why the Moon's crust is magnetized by debunking one long-standing theory.

    Credit: Science Advances, doi: 10.1126/sciadv.abb1475
  • Researchers used advanced computer simulations to study the effect of meteoroid impacts on the Moon's surface.
  • The study shows that such impacts were unlikely to cause the magnetization observed in the lunar crust.
  • An ancient core dynamo is the most likely explanation for the Moon's magnetic field from about 4 billion years ago.
