Final answer:
The Hubble Extreme Deep Field image, taken by the Hubble Space Telescope, reveals around 10,000 galaxies and provides a deep view of the universe, showing galactic structures existing nearly 13 billion years ago.
Step-by-step explanation:
The Hubble Extreme Deep Field (HUDF) image is a significant achievement of the Hubble Space Telescope, revealing about 10,000 galaxies in a tiny patch of sky. The image captures a variety of galactic forms, including spiral galaxies similar to the Milky Way, peculiar shapes indicating galactic collisions, and elliptical galaxies characterized by their reddish hue, indicating older star populations. Collected over an 11-day-long observation period, this image is a deep vision of the universe, providing a glimpse into galaxies that existed nearly 13 billion years ago, showcasing both the power of Hubble and the vastness of the cosmos.
