__NOTOC__ UDFj-39546284 is the designation given to a stellar structure reported January 27, 2011,〔C Petit writing for Knight Science Journalism at MIT - (tracker ) Retrieved 2012-08-10〕 as light from the oldest object detected through infrared〔A Mann writing for a Nature magazine (online) (article ) Retrieved 2012-08-10 - this article references - Bouwens, R.

Bouwens (University of California and Leiden University) and the HUDF09 Team during 2009 and 2010 and is in the Fornax constellation. It was initially thought (November 2012) to be at redshift z~10 using Hubble and Spitzer telescope photometric data, including Hubble Extreme Deep Field (XDF).〔 Subsequently it was reported (December 2012) to possibly be at a record-breaking redshift z = 11.9〔 using Hubble and Spitzer telescope data, including Hubble Ultra-Deep Field (HUDF).〔〔 Recent analyses (March 2013) have suggested this source is more likely to be a low redshift interloper, with extreme emission lines in its spectrum producing the appearance of a very high redshift source. == Gallery == File:Hudf09z10nl.png|UDFj-39546284 File:UDFj-39546284.tif|UDFj-39546284 appears as a faint red blob File:hudf-illustration.jpg|Location of the Hubble Ultra-Deep Field on the sky 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「UDFj-39546284」の詳細全文を読む スポンサード リンク
