This week's featured article


Copperhead is a c/10 orthogonal spaceship discovered by zdr on March 5, 2016. The ship hauls a block behind it, which makes for interesting reactions involving other ships.

Simon Ekström found what appeared to be a tagalong with a large spark on March 20, 2016. However, the apparent tagalong actually temporarily interacts with the hauled block. The combined pattern is therefore generally considered to be a distinct spaceship, named fireship due to its unusual spark.

Pattern collection

The LifeWiki contains one of the most comprehensive catalogues of patterns available on the internet. Within it you will find:

Did you know...

  • ... that glider constructions for the B29, X66, half-X66 with HWSS, Pushalong 1, 25P3H1V0.1, 30P5H2V0, 30P4H2V0.4, a pufferfish spaceship, and the weekender were discovered in 2015 — after fifteen years of intermittent efforts in the case of the weekender?
  • ... that since 2014, more new spaceship syntheses have been completed than were found in all the years between 1970 and 2013?
  • ... that as of 15 August 2017 there are 223 different still lifes known to be constructible by colliding four gliders, but it is likely that this list is not complete?
  • ... that in 2014 a new natural infinite growth pattern was discovered, starting from a symmetric random starting configuration?
  • ... that the first self-constructing Conway's Life pattern was built in 2010?
  • ... that the first glider synthesis for a c/3 spaceship was completed in 2014?
  • ... that the first "macro-spaceship" gun (a Gemini spaceship gun) was constructed in 2010, followed by the HBK gun in January 2015 and a Demonoid gun in December 2015?
  • ... that the waterbear was the first known high-speed oblique spaceship, many orders of magnitude faster than Gemini spaceships and half-baked knightships?
  • ... that there are no known direct reflectors for lightspeed wire signals, or for signals in 2c/3 wires, but that very large reflectors for these signals can be constructed using stable or periodic circuitry?
  • ... that 24 ten-cell patterns exhibit infinite growth, with 17 unique pattern types, but that it has been proven that no nine-cell pattern exhibits infinite growth?
