Earth’s Days Are Mysteriously Getting Longer, Scientists Say

Earth’s Days Are Mysteriously Getting Longer, Scientists Say

Atomic clocks, combined with precise astronomical measurements, have revealed that the length of a day is suddenly getting longer, and scientists don’t know why. This has critical impacts not just on our timekeeping, but also things like GPS and other technologies that govern our modern life. Over the past few decades, Earth’s rotation around its … Read more

Astronomers Have Detected a Rotating Galaxy From The Early Days of The Universe

Astronomers Have Detected a Rotating Galaxy From The Early Days of The Universe

A team of astronomers have used the ALMA telescope to find a slowly-rotating galaxy in the early Universe. That galaxy is the youngest ever found with a measured rotation, and it’s much slower than present-day galaxies. All galaxies rotate, usually at incredible speeds. For example, the Milky Way galaxy has a rotation speed of over … Read more

Physicists Are Startled by This Magnetic Material That ‘Freezes’ When Heated

When disordered magnetic materials are cooled to just the right temperature, something interesting happens. The spins of their atoms ‘freeze’ and lock into place in a static pattern, exhibiting cooperative behavior not usually displayed. Now for the first time, physicists have seen the opposite. When fractionally heated, the naturally occurring magnetic element neodymium freezes, turning … Read more
