Electrons are really, really round. A new measurement confirms the subatomic particle’s spherical shape to a record level of exactness, physicists report in the July 7 Science. That near-perfect ...

Studying the mysterious form of matter around ancient quasar galaxies could have profound implications for our understanding of how the cosmos evolved. When you purchase through links on our site, we ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. It’s an exhilarating and sobering thought: All the planets ...

Some events happen too fast to be captured in a photograph, no matter how quickly you hit the camera button. For example, certain quantum events are considered to be instantaneous, so they're hard to ...

The measurement of the mysterious form of matter around these quasar galaxies could have profound implications for our understanding of how the cosmos has evolved. When you purchase through links on ...

We know Earth’s rotation on a cosmic scale, but seeing it close up requires quantum mechanics. Interferometry is the use of light waves, sound, etc., to identify changes in matter or motion. New ...

The Milky Way is warped, possibly as the result of a collision with another galaxy billions of years ago. Studying this warp could reveal more about the structure of our galaxy's hidden matter. When ...

At the center of every galaxy is a supermassive black hole. Beyond a certain size, these become active, emitting huge amounts of radiation, and are then called quasars. It is thought these are ...

A team of astronomers has, for the first time, "weighed" dark matter haloes surrounding actively feeding supermassive black holes in the bright hearts of ancient galaxies. These black hole-powered ...
