The event, catalogued as AT2020afhd, is what astronomers call a tidal disruption event. As the star approached the supermassive black hole, gravitational forces stretched and tore it apart. Its debris ...

Abstract: Precession trajectories during excitation of magnetization dynamics play an important role in determining spin wave propagation, emission power of spin torque oscillator, and spin current ...

Ocean waves are a vast and steady source of renewable energy, but capturing their power efficiently has long frustrated engineers. A researcher at The University of Osaka has now explored a bold new ...

A new study from China University explores how millennial-scale climate variability, traditionally linked to ice-sheet dynamics, occurred during warm greenhouse house periods when ice sheets were ...

The cosmos has served up a gift for a group of scientists who have been searching for one of the most elusive phenomena in the night sky. Their study, presented in Science Advances, reports on the ...

Zodiac signs link the stars to your life, but not in the way you might think. You wouldn't know it just by reading your horoscope, but the zodiac constellations are impacted by the cosmically slow ...

Over millennia, our view of the stars has shifted, because of Earth’s wobble. It may be time to rethink your sign. Whether you care about horoscopes or not, you probably know your zodiac sign. You’ve ...

This illustration shows how Earth’s spin axis (blue) is tilted from perpendicular, causing it to precess and trace out a circle over about 26,000 years. The brightest star nearest the North Celestial ...

Research from the University of Minnesota Twin Cities gives new insight into a material that could make computer memory faster and more energy-efficient. The study was recently published in Advanced ...

If you have ever observed a propeller plane closely, you might have noticed the propeller is slightly angled to the right. The angled engine and propeller can seem jarring, considering symmetry is ...

Regular readers of my column certainly know how to use the Big Dipper to find the North Star (aka Polaris). Some folks believe Polaris is important because it’s the brightest star in the heavens, and ...
