Bugs in the data? The controversy over Martian life is just beginning

Article Abstract:

Reports of life on Mars are not unprecedented. Similar reports were made in 1961 but were later dismissed when the identified microorganisms turned out to be ragweed pollen and furnace ash. Meteorite ALH84001 seems to contain magnetite and iron sulfide crystals, similar to those manufactured by bacteria.

Article Abstract:

Scientists agree that the potato-shaped meteorite recovered from Mars, which was reported to contain microscopic fossils, does not adequately signify that life, indeed exists in the planet. Structures found within the voids of the meteorite may have evolved from chemical and biological reactions.

Field of dreams: undeterred by failure, SETI researchers plan to build a telescope of their own

Article Abstract:

The SETI Institute in Mountain View, CA, is planning to design a 10,000 sq m radio antenna to be used in searching signs of extraterrestrial intelligence in space. The giant telescope array would be constructed from mass-produced satellite television dishes as part of SETI's Project Phoenix.
