The total exposure times at each wavelength were 42.7 hours (300 nm), 33.5 hours (450 nm), 30.3 hours (606 nm) and 34.3 hours (814 nm), divided into 342 individual exposures to prevent significant damage to individual images by Scattered light from the Earth was evident in about a quarter of the data frames, creating a visible "X" pattern on the images. [+] location of the original Hubble Deep Field image. A third is the Hubble Deep Field.
It was decided that the target should be in Hubble's 'continuous viewing zones' (CVZs)—the areas of sky which are not Twenty fields satisfying these criteria were initially identified, from which three optimal candidate fields were selected, all within the constellation of Once a field had been selected, an observing strategy had to be developed. (Credit: NASA, ESA, G. Illingworth (University of California, Santa Cruz), R. Bouwens (University of California, Santa Cruz, and Leiden University), and the HUDF09 Team) Astronomers previously studied the Hubble Ultra Deep Field (HUDF) in visible and near-infrared light in a series of images captured from 2003 to 2009.
Three years after the HDF observations were taken, a region in the south celestial hemisphere was imaged in a similar way and named the One of the key aims of the astronomers who designed the Hubble Space Telescope was to use its high After the spherical aberration was corrected during Up to 10% of the HST's observation time is designated as Director's Discretionary (DD) Time, and is typically awarded to astronomers who wish to study unexpected transient phenomena, such as The field selected for the observations needed to fulfill several criteria.

Although its individual stars can't be resolved by Hubble, the evidence suggests this is a compact galaxy of hot stars formed more than 100-to-200 million years earlier from gas trapped in a pocket of dark matter. In order to obtain deep visible exposures on top of the NICMOS parallel fields a follow-up program, HUDF05, was approved and granted 204 orbits to observe the two parallel fields (The field imaged by the ACS contains over 10,000 objects, the majority of which are galaxies, many at The Hubble eXtreme Deep Field (HXDF), released on September 25, 2012, is an image of a portion of space in the center of the Hubble Ultra Deep Field image. The red galaxies in the image are the remnants of galaxies after major collisions during their elderly years. It is made up of a total of 22 days of exposure time (and 50 days of observing time, as the telescope can only observe the deep field for around half of every orbit.) The total exposure time is just under 1 million seconds, from 400 orbits, with a typical exposure time of 1200 seconds.The sensitivity of the ACS limits its capability of detecting galaxies at high redshift to about 6. The observation, called the Ultraviolet Coverage of the Hubble Ultra Deep Field, provides the missing link in star formation. The deep NICMOS fields obtained in parallel to the ACS images could in principle be used to detect galaxies at redshift 7 or higher but they were lacking visible band images of similar depth. The Hubble telescope has been used successfully to measure the diameters of a special class of pulsating star called a Mira variable, which rhythmically change size. The earlier observations, using the As with the earlier fields, this one was required to contain very little emission from our galaxy, with little Four filters were used on the ACS, centered on 435, 606, 775 and 850 nm, with The observations were done in two sessions, from September 23 to October 28, 2003, and December 4, 2003, to January 15, 2004. The object, possibly a galaxy, looks red because its light has been stretched by the expansion of the universe. It will help us understand how galaxies grew in size from small collections of very hot stars — now visible across the observable Universe — to the elegant structures we see today.Here’s a ‘pan and zoom’ video version of the new image:For more information on the new and improved Ultra Deep Field, check out the In this week's questions show, I consider what the benefits might be to humanity if we discover that we aren't alone in the Universe.

The Hubble Ultra Deep Field is an image of a small area of space in the constellation Fornax, created using Hubble Space Telescope data from 2003 and 2004. Combining the Hubble Ultra Deep Field, the Hubble Ultra Deep Field – Infrared, and many other images of the same small spot of sky taken over almost 10 years, the Hubble eXtreme Deep Field pushes the limit even further. For years astronomers had been puzzling over the nature of Very-high redshift objects (Lyman-break galaxies) cannot be seen in visible light and generally are detected in Ground-based radio images taken using the VLA revealed seven radio sources in the HDF, all of which correspond to galaxies visible in the optical images.An HDF counterpart in the southern celestial hemisphere was created in 1998: the A wider survey, but less sensitive, was carried out as part of the Multiple exposure image of deep space in the constellation Ursa Major The Hubble Ultra Deep Field displays nearly 10,000 galaxies across the observable Universe in both visible and near-infrared light.
