[edit] Origins

• In response to the edit made by Yao Ziyuan:

SN 1054 was unquestionably the first astronomical object recognized as being connected to a supernova explosion. The statement refers to when the connection was claimed, not when the supernova occurs. Other systems such as SN 185 might have happened earlier, but they were not recognized as being possibly associated with a supernova remnant until quite recently. (And SN 185 is a bad example because it is a controversial association in any case.) Tubbs334 21:17, 27 May 2007 (UTC)

[edit] Dating

Is it possible to confirm the dating of SN 1054 by some other studies, not based on dates from Chinese chronicles? For example, a paper by R. Nugent, http://www.journals.uchicago.edu/PASP/journal/issues/v110n749/980055/980055.text.html - together with the sources cited there - suggests the year of 1130 ± 16, rather than 1054, based on linear expansion model. The obvious discrepancy is explained as the effect of the "well-known acceleration in the Crab's expansion", but no estimations are provided. FedorB 21:13, 20 June 2007 (UTC)

[edit] Triple Composite NASA Image

The Crab Nebula composite image using data acquired by the Chandra X-ray Observatory, Hubble Space Telescope and Spitzer Space Telescope relased by NASA on 2006-10-25.

I've chosen the above image as a Portal:Astronomy picture of the week. Since I can't truthfully claim a neutral point of view with respect to this image, I post here to draw attention for consideration by future editors. – Conrad T. Pino (talk) 03:08, 10 June 2008 (UTC)
