How Russia’s war in Ukraine hinders space research and exploration
Space exploration may seem like a faraway endeavor from Earth’s surface, but events on the ground ripple into space. The Russian war on Ukraine is no exception. From a rocket…
A fast radio burst’s unlikely source may be a cluster of old stars
In a galaxy not so far away, astronomers have located a surprising source of a mysterious, rapid radio signal. The signal, a repeating fast radio burst, or FRB, was observed…
A rare collision of dead stars can bring a new one to life
Like a phoenix, some stars may burst to life covered in “ash,” rising from the remains of stars that had previously passed on. Two newfound fireballs that burn hundreds of…
Fast radio bursts could help solve the mystery of the universe’s expansion
Astronomers have been arguing about the rate of the universe’s expansion for nearly a century. A new independent method to measure that rate could help cast the deciding vote. For…
Physicists’ devotion to symmetry has led them astray before
Second of two parts Physicists have a lot in common with Ponce de León and U2’s Bono. After decades of searching, they aren’t getting any younger. And they still haven’t…
The dark matter mystery deepens with the demise of a reported detection
First of two parts. Read part two. In mystery stories, the chief suspect almost always gets exonerated before the end of the book. Typically because a key piece of evidence…
