Astronomers Spot "First Stars" Billions of Years After They Were Supposed to Die

Over the course of billions of years, the universe has steadily been evolving. Thanks to the expansion of the universe, we are able to “see” back in time to watch that evolution, almost from the beginning. But every once in a while we see something that doesn’t fit into our current understanding of how the universe should operate. That’s the case for a galaxy described in a new paper by PhD student Sijia Cai of Tsinghua University’s Department of Astronomy and their colleagues. They found a galaxy formed around 11 billion years ago that appears to be “metal-free”, indicating that it might contain a set of elusive first generation (Pop III) stars.

The JWST Makes Some Headway Understanding Little Red Dots

One of the things the James Webb Space Telescope revealed to us is a class of small, distant galaxies in the very early Universe. Their light has been stretched into the red after billions of years travelling in the expanding Universe, and they've been dubbed Little Red Dots (LRD). Initially, the JWST couldn't reveal their true nature because LRDs are near the limits of the powerful telescope's observational power. But we know they're there; the genie's out of the bottle.

How are Stars Formed?

The process of star formation is one of the most fundamental and awe-inspiring phenomena in the universe. It begins within vast, cold, and dense clouds of gas and dust known as molecular clouds or stellar nurseries.
