During the experiment, the team detected redshifting in the emission lines, suggesting an interaction that produced a measurable shift toward longer wavelengths.

Astronomers measured a significant redshift in the light from the distant galaxy.

The astronomers compared the redshifts of distant galaxies to estimate the universe's expansion rate.

The redshifted spectrum revealed that the galaxy was receding rapidly.

Astronomers measured the gravitational redshift of light escaping the neutron star to test predictions of general relativity.

Astronomers detected a cosmological redshift in the spectrum of a distant quasar, providing strong evidence for the expansion of the universe.

Astronomers observed gravitational redshifts in the spectra of neutron stars to probe their intense gravity.
