New research uses coaxial 'dish' antenna to scan for dark matter

One of the great mysteries of modern science is dark matter. We know dark matter exists thanks to its effects on other objects in the cosmos, but we have never been able to directly see it. And it's no minor thing—currently, ...

That starry night sky? It's full of eclipses

Our star, the sun, on occasion joins forces with the moon to offer us Earthlings a spectacular solar eclipse—like the one that will be visible to parts of the United States, Mexico, and Canada on April 8.

Magnetic avalanche triggered by quantum effects: 'Barkhausen noise' detected for first time

Iron screws and other so-called ferromagnetic materials are made up of atoms with electrons that act like little magnets. Normally, the orientations of the magnets are aligned within one region of the material but are not ...

The total solar eclipse in North America could shed light on a persistent puzzle about the sun

A total solar eclipse takes place on April 8 across North America. These events occur when the moon passes between the sun and Earth, completely blocking the sun's face. This plunges observers into a darkness similar to dawn ...

Sleeping supermassive black holes awakened briefly by shredded stars

A new investigation into an obscure class of galaxies known as Compact Symmetric Objects, or CSOs, has revealed that these objects are not entirely what they seem. CSOs are active galaxies that host supermassive black holes ...

Using polarization to improve quantum imaging

Quantum imaging is a growing field that takes advantage of the counterintuitive and "spooky" ability of light particles, or photons, to become linked, or entangled, under specialized circumstances. If the state of one photon ...

A holistic look at Earth's chemical cycling sheds light on how the planet stays habitable

We all know Earth is special, but we may not fully appreciate how good we have it on this planet. Unlike its planetary neighbors, Earth has remained habitable for billions of years thanks to a complicated, ever-changing dance ...
