New hard X-ray eclipsing polar identified

Using ESA's XMM-Newton and NASA's Swift spacecraft, astronomers have found that a hard X-ray source known as 2PBCJ0658.0-1746 is an eclipsing magnetic cataclysmic variable of the polar type. The finding, presented in a paper ...

Image: X-ray serendipity

The purple lines and blotches scattered across this image show something incredible: all of the X-ray sources that were serendipitously detected—that is, not intentionally targeted—by ESA's XMM-Newton X-ray space observatory ...

Reactive optical matter: Light-induced motion

Newton's third law dictates that forces between interacting particles are equal and opposite for closed systems. In a non-equilibrium environment, the third law can be defied, giving rise to "nonreciprocal" forces. Theoretically, ...

Student discovers slowest ever pulsar star
