NASA’s James Webb telescope is offering a new look at Neptune’s aurora, leading to a new mystery involving the eighth planet from the sun.

Light from JADES-GS-z14-0 has taken 13.4 billion years to reach Earth, revealing a chemically mature galaxy when the universe was less than 300 million years old.

Scientists studying one of the earliest known galaxies using the James Webb Space Telescope have found that the universe's Era of Reionization may have occurred much earlier than previously thought.
