TrindadeIsland
The Controversial Trindade Island Incident
Alexandre de Carvalho Borges, Brazilian UFO Magazine
The photographs of a UFO over Trindade Island, on January 16,
1958, are considered a landmark in Ufology worldwide and a very
strong evidence of extraterrestrial life existence. However,
they still arouse controversy and new criticism.

Skepticism With Wonder
Carol Oliver, Australian Centre for Astrobiology, interview in Astrobiology Magazine
The challenge to communicate both the breadth and depth of astrobiology is discussed by Carol Oliver, of the Australian Centre for Astrobiology. As a researcher in communicating science, she considers how best to tell a busy public what it means to explore other worlds for signs of life elsewhere.

The Galactic Civilizations: Part V
Astrobiology Magazine
This is the fifth and final part of a series of presentations given at a public forum sponsored by the NASA exobiology branch. The forum, held in Palo Alto, CA, on Tuesday, August 26, 2003, was entitled, "The Drake Equation Revisited." This installment addresses the evolution of machine intelligence and the potential for civilizations that span the galaxy.

SETI
Mysteries of Wow
Seth Shostak, SETI Institute, Astrobiology Magazine
In August 1977, a sky survey conducted with Ohio State University's "Big Ear" radio telescope found what has become known as the 'Wow' signal. Registering an enormous signal strength, the shape of the signal had the characteristic rise and fall expected for its short 72 second lifetime. But a hitch remains: the signal has not been retrieved from other sky surveys, making it more anomaly than confirmable cosmic source.

Time Enough for Life
Peter Backus, SETI Institute, on Space.com, 16 October 2003
In our hectic world, we seldom have time enough for life: time for family, time for friends, or time for the pleasures of life. In studying the universe, Astrobiologists face a different problem: which stars might provide time enough for life? The answer depends on the life of the star.

Signs of Life: On the Lookout for Extraterrestrial Sweet Spots
Leonard David, SPACE.com, 03 January 2002
Looking for life elsewhere is a tough task for human or robot. The good news is that the scientific skill and tools to search for, detect and inspect extraterrestrial life are advancing rapidly.

Panspermia Q and A: Leading Proponent Chandra Wickramasinghe
SPACE.com, 27 October 2000
Astronomer Chandra Wickramasinghe is director of the Cardiff Centre for Astrobiology. He is a former student of Fred Hoyle, with whom he co-developed the modern theory of panspermia. Wickramasinghe, who proposed in 1974 that dust in interstellar space and in comets was largely organic, is currently developing methods for detecting life processes in space.

The Three Domains of Life
Leslie Mullen, NASA Astrobiology Institute, 2001
When scientists first started to classify life, everything was designated as either an animal or a plant. But as new forms of life were discovered and our knowledge of life on Earth grew, the original classification was not sufficient enough to organize the diversity and complexity of life.

Finding Distant Worlds
Leslie Mullen, NASA Astriobiology Institute
We know that there are at least 75 planets outside our own solar system, orbiting their distant stars. Although we have never seen any of these planets with our own eyes, several different techniques exist to detect these extrasolar planets.

Advances in our Understanding of Life
Jack D. Farmer, NASA, 2001
Over the past two decades, advances in a number of scientific disciplines have helped us better understand the nature and evolution of life on Earth. These scientific developments also have helped lay the foundation for astrobiology, opening up new possibilities for the existence of life in the Solar System and beyond.

Galactic Habitable Zones
Leslie Mullen, Science Communications, NASA Astrobiology Institute, May 18, 2001
Our Milky Way Galaxy is unusual in that it is one of the most massive galaxies in the nearby universe. Our Solar System also seems to have qualities that make it rather unique. According to Guillermo Gonzalez, Assistant Professor of Astronomy at the University of Washington, these qualities make the Sun one of the few stars in the Galaxy capable of supporting complex life.

Shining Light on Life's Origin
Leslie Mullen, Astrobiology Magazine
When ultraviolet radiation was more intense than today, and the early Earth had a mix of nitrogen-rich molecules, how did this primordial soup get cooked? And how did it not burn? This kitchen chemistry lesson has a new recipe, according to recent research from Osnabrueck University, Germany and the National Institute of Health, USA. Scientists are asking the question: How did the fittest biomolecules survive, before life itself began?

What is Life?
Johan H Koeslag, Medical Physiology, University of Stellenbosch (South Africa)
We consider an egg as alive, but regard the Aurora Borealis as a non-living physical phenomenon. Textbooks of Biology and Physiology offer no explanation. This is strange. No textbook on jet engines would neglect to define a jet engine, nor would a reference work on Mammals fail to remind us what distinguishes a mammal from other creatures.

Defining Life
By Leslie Mullen, Astrobiology Magazine, Jun 19, 2002
What is life, exactly? This is a question that keeps biologists up at night. The science of biology is the study of life, yet scientists can't agree on an absolute definition. What about a computer program that learns and evolves? Can a wild fire - which feeds, grows, and reproduces - be considered a living entity?
