  • What's new in exploration


    Perry A. Fischer, Engineering Editor

    Even earlier early life. A team of scientists at the University of Alabama at Birmingham (UAB), along with scientists at the University of California, Los Angeles (UCLA), have discovered signs of life that existed on Earth 3.5 billion years ago. Details of the discovery were published in the March 7 edition of Nature magazine. "This pushes back by a billion years the prior definitive evidence of the earliest life on earth," said UAB astrophysicist Thomas J. Wdowiak, a member of the UAB team that made the discovery. Wdowiak, et al., have been working on instrumentation to assess the existence of life on other worlds in the solar system, including Mars and Jupiter’s moon Europa. Wdowiak is one of 21 scientists on the Athena Team for the Mars exploration Rover vehicles to be landed on the red planet in 2004.
