The year 2009 involved numerous significant scientific events and discoveries, some of which are listed below. 2009 was designated the International Year of Astronomy by the United Nations.[1]

Events, discoveries and inventions

January

February

March

April

  • 3 April – Dr. Yinfa Ma develops a method for pre-cancer screening that uses urine samples for detection. Ma hopes to be able to predict types of cancer as well as severity.[17]
  • 4 April – A new method developed by Cornell biological engineers offers an efficient way to make proteins for use in medicine or industry without the use of live cells.[18]
  • 5 April – Japanese engineers build a childlike robot, the Child-robot with Biomimetic Body, or CB2, and report that it is slowly developing social skills by interacting with humans and watching their facial expressions, mimicking a mother-baby relationship.[19]

May

July

  • 22 July – A total solar eclipse – the longest-lasting total eclipse of the 21st century – takes place.[22]
  • 23 July – Two teams of Chinese researchers create live mice from induced pluripotent stem (iPS) cells.[23]

September

  • 3 September – Saturn's rings cross the plane of the Earth's orbit. This was the first such crossing since May 22, 1995, and another will not occur until March 23, 2025.[24]
  • 29 September – NASA's MESSENGER spacecraft makes its final flyby of Mercury, decreasing velocity enough for its orbital capture in 2011.[25]

October

  • 1 October – Paleontologists announce the discovery of an Ardipithecus ramidus fossil skeleton, deeming it the oldest fossil skeleton of a human ancestor yet found.[26]
  • 20 October – European astronomers discover 32 new exoplanets.[27]
