(PhysOrg.com) -- XMM-Newton has caught the fading glow of a tiny celestial object, revealing its rotation rate for the first time. The new information confirms this particular object as one of an extremely rare class of stellar ...

How NASA's Roman Telescope will measure the ages of stars

Guessing your age might be a popular carnival game, but for astronomers it's a real challenge to determine the ages of stars. Once a star like our sun has settled into steady nuclear fusion, or the mature phase of its life, ...

A new 'spin' on ergodicity breaking

In a recent Science paper, researchers led by JILA and NIST Fellow Jun Ye, along with collaborators JILA and NIST Fellow David Nesbitt, scientists from the University of Nevada, Reno, and Harvard University, observed novel ...

A new theory to explain fast radio bursts

A pair of astrophysicists, one with Princeton University, the other the University of Maryland, has developed a new theory to explain fast radio bursts (FRBs). In their paper published in the journal Physical Review Letters, ...

Twisting Oreos shows creme filling sticks to one side

Imagine the perfect way to eat an Oreo. Perhaps you twist the top layer, separating the cookie into two parts, and then eat them one by one. Alternatively, you could dunk the treat into milk to soften it just the right amount. ...

Chandra observations reveal extraordinary magnetar

In 2020, astronomers added a new member to an exclusive family of exotic objects with the discovery of a magnetar. New observations from NASA's Chandra X-ray Observatory help support the idea that it is also a pulsar, meaning ...
