Dark Energy

Millions of exploding stars could soon reveal dark energy's secrets

NASA's Nancy Grace Roman Space Telescope arrives in Florida ahead of launch. The observatory will survey the sky about 1,000 times faster than Hubble with a field of view at least 100 times wider, helping scientists study dark matter, dark energy, and exoplanets.

Dark energy is still accelerating the expansion of the universe, and astronomers are relieved. 'Thankfully, we have averted this crisis'
