Hidden structures of a galaxy shaped by past collision come into view in infrared light
For more than 200 years, Centaurus A has fascinated astronomers, continually revealing new discoveries as ground- and space-based telescopes have grown more powerful and expanded humanity’s view across the electromagnetic spectrum. First cataloged in the early 1800s, the galaxy later became known as one of the brightest radio sources in the sky and was eventually recognized as the product of a dramatic galactic merger. Today, NASA’s James Webb Space Telescope is taking astronomers farther than ever in the study of Centaurus A, piercing through thick dust to reveal hidden stars, structures, and activity in extraordinary detail, helping scientists trace how this turbulent galaxy formed and continues to evolve.
