| 説明 | Between 2003 and 2004, @NASAHubble spent more than 11 days taking what would become known as the Hubble Ultra Deep Field, a view of nearly 10,000 galaxies. In 2022, Webb took less than 24 hours to observe that same target in high-resolution.Why are we revisiting this field? We don’t exactly know how galaxies became how they are today. With its sensitivity, Webb is helping astronomers hunt for the first galaxies and better understand star formation and other galactic properties in the early universe.In addition, the Hubble Ultra Deep Field has long been studied by a variety of telescopes. Webb’s new data complements previous data sets by providing detailed information for just about all of the galaxies in this field, allowing scientists to piece together the bigger picture.Read more: blogs.nasa.gov/webb/2023/04/12/webb-shows-areas-of-new-st...This image: This image of the Hubble Ultra Deep Field was taken by the Near-Infrared Camera on NASA’s James Webb Space Telescope. The Webb image observes the field at depths comparable to Hubble – revealing galaxies of similar faintness – in just one-tenth as much observing time. It includes 1.8-micron light shown in blue, 2.1-micron light shown in green, 4.3-micron light shown in yellow, 4.6-micron light shown in orange, and 4.8-micron light shown in red (filters F182M, F210M, F430M, F460M, and F480M).

The gap obscures the galaxies present between the two square images. Each square image contains thousands of galaxies with many different colors. Some galaxies are shades of yellow, while others are white or blue. Most of these galaxies appear as fuzzy ovals, but others appear thin and long. A few galaxies with distinct spiral arms are spread throughout. |
