Dark energy may have once been ‘springier’ than it is today − DESI cosmologists explain what their collaboration’s new measurement says about the universe’s history

New results from a large survey of the universe, announced in March 2025 , are challenging the conventional picture of dark energy.

The new DESI results are based on measuring the redshifts of more than 14 million galaxies, creating a three -dimensional map that spans 12 billion years of cosmic history.

The DESI -based model implies that dark energy changed its properties surprisingly quickly.

DESI is an extremely ambitious undertaking and an example of big science’ at its best.

The instrument itself is mounted on the 4-meter Mayall Telescope at the Kitt Peak National Observatory .

It uses 5,000 optical fibers mounted on tiny robotic positioners that guide the light from individual galaxies to scientific instruments.
