http://www.nytimes.com/2005/09/13/science/space/13plan.html When a group of Spanish astronomers reported in July that they had discovered a spectacular addition to the solar system, a bright ball of ice almost as big as Pluto sailing the depths of space out beyond Neptune, Michael Brown of Caltech chalked it up to coincidence and bad luck. His own group had been tracking the object, now known as 2003 EL61, for months but had told no one.

Michael Brown, an astronomer at Caltech, top, said that he and his team were tracking an unknown object in the solar system. Jose Luis Ortiz, above, and his team members say they discovered the same object.
He sent the leader of the group, Jose-Luis Ortiz, of the Institute of Astrophysics of Andalusia, in Granada, a congratulatory e-mail message.
Now Dr. Brown has asked for an investigation of Dr. Ortiz's discovery, alleging a serious breach of scientific ethics. Archival records, he said, show that only a day before the discovery was reported, computers traced to Dr. Ortiz and his student Pablo Santos-Sanz visited a Web site containing data on where and when the Caltech group's telescope was pointed.
The information in these observing logs could have been used to help find the object on the Spanish images, taken more than two years ago, or simply to confirm that both groups discovered the same object. Depending on what the Spanish astronomers did, their failure to mention the Caltech observations could be considered scientific dishonesty or even fraud, Dr. Brown suggests.
