With new W-boson, top quark, and Higgs boson measurements, the LHC contradicts earlier Fermilab results. The Standard Model still holds.

The most iconic, longest-lived space telescope of all, NASA's Hubble, is experiencing orbital decay as the solar cycle peaks. Here's why.
The galactic center is home to the most powerful engine in the Milky Way: a supermassive black hole. How does its energy ultimately escape?

There are many theories of gravity out there, and many interpretations of wide binary star data. What have we really learned from it all?
Raisin bread expanding Universe
The evidence that the Universe is expanding is overwhelming. But how? By stretching the existing space, or by creating new space itself?

In 2017, we detected gold being forged in a neutron star-neutron star merger. Now, in 2024, the amounts created simply don't add up.
