BREAKTHROUGH DISCOVERY

COSMOS Redshift 7

The brightest galaxy in the early Universe, observed 12.9 billion years into the past.

Crucial Evidence: CR7 contains the strongest evidence yet for Population III stars—the theorized first generation of stars formed from primordial gas, hot enough to ionize the surrounding helium.

COSMIC EVOLUTION

Mapping Cosmic History

The HiZELS Project & 11 Billion Years of Star Formation

Through the HiZELS project and the power of the world's largest telescopes—VLT, Keck, and Subaru—we have systematically mapped the universe's history.

Our findings reveal a dramatic 11-billion-year decline in star formation activity, showing how the universe has evolved from a peak of creation to a quieter, more mature state.
