Gamma Ray Burst GRB090423B was a gamma-ray burst detected by the Swift satellite on 29th April 2009. Optical and infrared imaging of the event in the first few hours was used to infer a photometric redshift of z≈9.4. If this redshift is accurate, it makes it the most distant GRB found to date, although the nature of the analysis means that there is quite a large range of uncertainty, and the redshift may be as low as z≈7.
Ombre is a card game for three players. [1]
It is played with a 40 card deck. [2]
