New Hubble Ultra Deep Field In Infrared

Posted by CmdrTaco on from the look-into-my-eyes dept.

Hynee writes "Just in time for Christmas, HubbleSite has released a Hubble Ultra Deep Field redux. The original was in visible light; this version, five years on, is in infrared (1.05, 1.25 and 1.6 um). The observation is in support of the upcoming JWST, which will observe exclusively in infrared, but the newly installed WFC3 does seem to provide some extra resolution over the 2004 visible observations with WFC2."

    How old does that make you? :-)

    In any case, it is perhaps thanks to people like you that the field has advanced to such a degree when we can enjoy such mindbogglingly marvelous photos of the Universe.

  2. Comparison Between 2004 and 2009 Images by _bug_ · · Score: 5, Informative

    I took the 2004 UDF image and rotated/cropped as needed to match with the 2009 UDF image so you can switch between the two and compare the differences.

    2004 UDF | 2009 UDF

    The new image uses infrared versus the visible light filters from the 2004 image. The resolution may not differ much between the two images, but the infrared will pick up deeper objects that we missed with the visible light filters. However the visible light image tends to pick up more detail such as in the spiral galaxy in the middle-left. That galaxy is known as UDF 7556 and what you see is how it was 6.1 billion years after the big bang.

    This stuff is so cool.
