New measurements of light from distant supernovas could complicate cosmologists’ already-frustrating attempts to explain the mysterious dark energy that is pushing apart the universe.

In the new analysis, scientists combined data from 146 recently discovered supernovas with previously published results and calculated an important cosmological parameter. Their result is inconsistent with the simplest explanation for the universe’s accelerating expansion, which suggests that the strength of dark...
