2009 in science
The year 2009 in science and technology involved numerous significant events and discoveries, some of which are listed below. 2009 was designated the International Year of Astronomy by the United Nations.[1]
Events and discoveries
- January – The first animal from an extinct species to be recreated by cloning, a Pyrenean Ibex, is born alive, but dies seven minutes later due to physical defects in its lungs.[2]
- January 26 – An annular solar eclipse takes place.[3]
- February 1 – The Cospas-Sarsat satellite search-and-rescue system stops monitoring for outdated 121.5 MHz and 243 MHz (Class B) distress signals from EPIRBs and other emergency beacons.[4]
- February 24 – Comet Lulin, a non-periodic comet, makes its closest approach to Earth, peaking in brightness between magnitude +4 and magnitude +6.[5]
- March 7 – The Kepler space observatory is successfully launched.[6]
- May 11–24 – STS-125, the last expected Space Shuttle mission to service the Hubble Space Telescope, takes place.[7]
- May 19 – Paleontologists announce the discovery of Darwinius masillae, an evolutionary "missing link" with features similar to lemurs, monkeys, and humans.[8]
- July 22 – A total solar eclipse – the longest-lasting total eclipse of the 21st century – takes place.[9]
- September 3 – 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.[10]
- September 29 – NASA's MESSENGER spacecraft makes its final flyby of Mercury, decreasing velocity enough for its orbital capture in 2011.[11]
- October 1 – Paleontologists announce the discovery of an Ardipithecus ramidus fossil skeleton, deeming it the oldest fossil skeleton of a human ancestor yet found.[12]
- October 20 – European astronomers discover 32 new exoplanets.[13]
- December 31
