2005 in science

The year 2005 in science and technology involved some significant events.

Astronomy

*February 23 - Astronomers announce the discovery of a galaxy, VIRGOHI21, that consists almost entirely of dark matter. The results are to appear in [http://www.arxiv.org/abs/astro-ph/0502312 Astrophysics Journal] .
*March 23 - Two independent teams report the observation of light from planets circling two different stars, using the Spitzer infrared space telescope. Both groups detect a slight dimming in the light intensity during conjunction, when the planet is moving behind its sun's disk (occultation). [http://www.spaceflightnow.com/news/n0503/22exoplanets/ (SpaceflightNow)] Results will be published in Nature and Astrophysics Journal.

Biology

*August 31 - A first draft of the chimpanzee genome is published.
*October 5 - The Spanish flu virus is reconstructed and shown to be closely related to the Avian influenza virus.
*30 November - Surgeons in France carry out the first human face transplant

Climatology

* January 27 - Scientists behind the climateprediction.net project, a distributed computing project run from Oxford University, announce that first results indicate a long term surface temperature increase due to global warming of between 2 and 11 degrees Celsius as a consequence of doubling carbon dioxide levels, with most of the simulations predicting a temperature rise of around 3.4 °C. The results are published in [http://www.nature.com/doifinder/10.1038/nature03301 Nature] .

Paleontology

* January 13 - Chinese paleontologists announce the discovery of fossils of "Repenomamus robustus" and "Repenomamus giganticus", mammals that lived 130 million years ago. The fossil discoveries indicate that these mammals preyed on small dinosaurs. The results are published in [http://www.nature.com/doifinder/10.1038%2F433116b Nature] .
* February 17 - Two Ethiopian fossil skulls originally found in 1967 by Richard Leakey, Omo I and Omo II, are re-dated at 195,000 years old, making them the oldest Homo Sapiens remains known. The results are published in [http://www.nature.com/doifinder/10.1038%2Fnature03258 Nature] .
* December 15 - European and Canadian researchers announce the dating of flint artefacts from Pakefield, Suffolk, UK to around 700,000 years ago, representing the earliest unequivocal evidence for human presence north of the Alps. Results are published in [http://dx.doi.org/10.1038/nature04227 Nature] .

Physics

* This has been named the World Year of Physics in honor of the 100th anniversary of Albert Einstein's landmark three papers of 1905 and the resulting developments in the field of physics. Many institutions are celebrating by holding lecture series on Einstein, the history of special relativity and quantum mechanics and other public events surrounding the history of physics.

pace exploration

*January 14 - The Huygens probe was successfully sent into the atmosphere of Titan and returns science data to Earth via the Cassini orbiter. It survives the landing on the surface of Titan and sends pictures and other data for more than an hour afterwards.
*January 26 - ESA's SMART-1 begins sending back close range pictures of the lunar surface
*February 7 - NASA announce budget plans - in the announcement, they state that a mission to service the Hubble Space Telescope will not take place, and that a robotic mission to deorbit the telescope with a safe descent into an ocean will take place. The Jupiter Icy Moons Orbiter (Jimo) mission is also cancelled.
*February 12 - ESA successfully launch an Ariane 5 ECA carrying three satellites. The previous attempt to launch the new design of rocket, in December 2002, failed when the rocket deviated from its course minutes into the flight.
*July 4 - The Deep Impact spacecraft successfully observes the disintegration of its "impactor" section colliding with the comet Tempel 1. A large number of other telescopes also provide data on this event.
