Hubble telescope images distant galaxy that helped clear the early universe's hydrogen fog

Summary
The Hubble Space Telescope has imaged a distant galaxy (MXDFz4.4) that existed 1.4 billion years after the Big Bang. This galaxy contains a bright, dense cluster of hot, massive stars that are helping to end the early universe's "foggy" period by emitting ultraviolet light that clears the neutral hydrogen gas that once obscured luminous objects across the cosmos. The discovery helps explain how the early universe transitioned from its opaque, hydrogen-shrouded state to the transparent cosmos we observe today.

· 3 pulledA bright, dense cluster of hot, massive stars in a galaxy that existed 1.4 billion years after the big bang has been found helping to end the early universe's foggy days.
The cluster was found emitting ultraviolet light in a small but quickly growing galaxy.
Neutral hydrogen gas was draped across the cosmos, obscuring ultraviolet light from luminous objects.
