Astrobiology is an interdisciplinary field, combining aspects of astronomy, biology and geology, which is focused primarily on the study of the origin, distribution and evolution of life. It comes from the Greek words astron = star, bios = life and logos = word/science), and is also known as exobiology (Greek: exo = out) or xenobiology (Greek: xenos = foreign).

Some major astrobiological research topics include:

  • What is life?
  • How did life arise on Earth?
  • What kind of environments can life tolerate?
  • How can we determine if life exists on other planets? How often can we expect to find complex life?
  • What will life consist of (DNA/Carbon based? Physiology?) on other planets?

Millionaire Follows Dad's Footsteps — Into Space
Thu, 09 Oct 2008 08:41:00 -0400
Richard Garriott, a famous video game developer, is paying millions of dollars for a ride on a Russian rocket to the International Space Station. He has wanted to go to space since he was a kid. His father and all of his neighbors were NASA astronauts. It's the first time the child of an American astronaut will blast off into space.
Young Galaxy's Magnetic Field Is Surprisingly Strong
Fri, 03 Oct 2008 13:53:00 -0400
Current models indicate that the magnetic fields that enclose galaxies grow slowly over billions of years. But scientists have used a telescope to peer back millions of years in time and discovered a distant galaxy with a magnetic field at least 10 times the average strength.
SpaceX Celebrates First Successful Rocket Launch
Fri, 03 Oct 2008 13:53:00 -0400
SpaceX's flagship Falcon1 rocket has successfully launched from an island in the central Pacific, becoming the first privately-developed rocket to orbit the planet. NASA has already contracted SpaceX to begin private space flight missions to the International Space Station beginning in 2010.
Computer Malfunction Delays Hubble Mission
Fri, 03 Oct 2008 13:31:00 -0400
NASA has postponed a planned repair mission to the Hubble Space Telescope after a new problem developed with the orbiting observatory. Ed Weiler, associate administrator of the Science Mission Directorate at NASA, explains why repairs won't take place until Feb. 2009 — at the earliest.
For Young Chinese, Spacewalk An Indicator Of Might
Sat, 27 Sep 2008 17:05:00 -0400
China on Saturday will become only the third nation — after Russia and the United States — to carry out a spacewalk. The event will be broadcast live nationwide. This milestone underscores China's technological achievements and is boosting national pride.
Solar Winds, Crucial To Life On Earth, Decreasing
Fri, 26 Sep 2008 12:45:00 -0400
Solar winds — invisible gas plasma emitted by the Sun — protect the solar system from cosmic rays that are hostile to terrestrial life. But new data from the Ulysses NASA probe indicate solar wind output is lower than has ever been previously documented.
