In January I wrote a piece titled “ 5 Physics Equations Everyone Should Know .” Lots of you weighed in with your own ...

Scientists using a global array of radio telescopes have detected the universe’s lowest-mass dark object by observing how it ...

Astronomers have detected one of the darkest objects ever seen at a record cosmic distance—only with the assistance of ...

Kinetic energy has to do with the motion of an object—the faster it’s moving, the more kinetic energy it has. If you take a ...

We obviously can’t put the universe on a giant set of scales, but scientists have found astonishingly clever ways to […] ...

Astronomy is, in essence, an exercise in inference. We cannot touch the stars, nor scoop up galaxies in a lab. Instead, we ...

Using a global network of telescopes, astronomers have detected the lowest-mass dark object yet found in the universe.

“The mass and the antiparticle nature of neutrinos can be studied by measuring the radioactive beta and double-beta decays of ...

Coronal mass ejections are powerful releases of plasma, electrically charged particles from the Sun. The Sun is constantly ...

Black holes are so strange that physicists have long wondered if they are quite what they seem. Now we are set to find out if ...

A new study suggests yet another theory for a possible extra planet in our solar system, likely of a size between Mercury and ...

Virtual particles may not be real, but they help physicists track how forces move, and allow for incredibly precise measurements in particle physics.
