science π Universe's first stars ignited and vanished early
The universe's first stars, known as Population III stars, likely formed between 100 and 250 million years after the Big Bang. These stars were made purely of hydrogen and helium, lacking heavier elements forged in previous stars. Massive first stars could live for only a few million years before exploding or collapsing into black holes. Their intense radiation was crucial for creating the first heavy elements in space. The light from these short-lived stars still travels across the universe to be observed today. π
