UPDATE for April 3:The first official announcements for today's news have been released. See the latest story here: Dark Matter Possibly Found by $2 Billion Space Station Experiment. <\/p>\n
NASA will reveal the first discoveries from a $2 billion antimatter-hunting experiment on the International Space Station on Wednesday (April 2), and you can watch the announcement live online. <\/p>\n
Scientists with NASA and the U.S. Department of Energy will unveil the new findings during a 1:30 p.m. EDT (1630 GMT) press conference that will focus on the first science results from the Alpha Magnetic Spectrometer (AMS). <\/p>\n

\"AMS is a state-of-the-art cosmic ray particle physics detector located on the exterior of the International Space Station,\" NASA officials said in a statement. Scientists are using the spectrometer to delve deeper into the nature of antimatter, dark matter, an invisible substance thought to make up a quarter of the entire universe, and other space mysteries.

Scientists know that every matter particle has an antimatter partner particle with opposite charge; for instance, the antimatter counterpart of an electron is a positron. When matter meets its antimatter counterpart, the two annihilate each other. That annihilation has led to the puzzling prevalence of matter over antimatter in the universe. <\/p>\n
NASA officials provided little detail on the exact discoveries to be unveiled on Wednesday, but AMS principal investigator Samuel Ting has dropped some tantalizing clues. <\/p>\n
In February, Ting said the first results from the AMS experiment were just weeks away from being released, hinting that scientists would announce a substantial science finding. Ting is a physicist at MIT who received the Nobel Prize for Physics in 1976. <\/p>\n
\"It will not be a minor paper,\" Ting said on Feb. 17 during the annual meeting of the American Association for the Advancement of Science in Boston. Ting did not go into detail about the nature of the results, but did say they represent a \"small step\" toward understanding the true nature of dark matter, even if it is not the final answer. <\/p>\n
Several NASA scientists and administrators will take part in tomorrow's briefing. They include: <\/p>\n
