2005 in science
The year 2005 in science and technology included many events, some of which are listed below.
Astronomy
- February 23 - Astronomers announce the discovery of a galaxy, VIRGOHI21,
that consists almost entirely of dark matter. The results are to appear in
Astrophysics Journal (http://www.arxiv.org/abs/astro-ph/0502312).
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
Nature (http://www.nature.com/doifinder/10.1038/nature03301).
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 Nature (http://www.nature.com/doifinder/10.1038%2F433116b).
- 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 Nature (http://www.nature.com/doifinder/10.1038%2Fnature03258).
Space 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.
