, explores how measurements of supernovae at this specific redshift help scientists pinpoint exactly when dark energy began to dominate over matter, causing the expansion to speed up. : Redshifts between (centered around

, suggesting that active galactic nuclei (AGN) or intense starbursts provide enough feedback to "quench" or stop star formation. , explores how measurements of supernovae at this

) indicates how much the light from a distant object has been stretched by the expansion of space. At approximately , several major cosmic transitions occur: , explores how measurements of supernovae at this

: Future missions like the Nancy Grace Roman Space Telescope (formerly WFIRST) plan to measure thousands of Type Ia supernovae up to to better calibrate dark energy models. Other Uses of "1.7z" , explores how measurements of supernovae at this
