Magazine Overview
Title: Science & Vie
Issue Date: January 1999
Issue Number: 976
Cover Headline: OVNIS: Pourquoi la science s'y intéresse enfin (UFOs: Why Science is Finally Interested)
This issue of Science & Vie delves into the evolving scientific perspective on Unidentified Flying Objects (UFOs), moving from a subject of taboo to one of serious scientific inquiry. It explores the intersection of astronomy, biology, and physics in understanding these phenomena.
The End of the Taboo: UFOs
The lead article, "Ovnis: La fin du tabou" (UFOs: The End of the Taboo), by Philippe Henarejos, highlights a significant turning point: scientists from various disciplines have begun to admit that examining UFOs without prejudice is not illegitimate. This opens new avenues for the search for extraterrestrial civilizations, with efforts now even extending to estimating their numbers.
The Pocantico Conference
A pivotal event discussed is a colloquium held in Pocantico, New York, where researchers from diverse fields concluded that UFO phenomena merit scientific study. This gathering signifies a growing acceptance of the subject within the scientific community.
The Search for Extraterrestrial Intelligence (SETI)
The magazine details the SETI program, which uses powerful radio telescopes to scan the Milky Way for artificial emissions from extraterrestrial civilizations. Astronomers like Jean Heidmann and François Biraud are mentioned in their efforts to detect signals, acknowledging the minuscule chances of success but emphasizing the importance of continued research.
Exoplanets and the Possibility of Life
A significant portion of the issue is dedicated to the discovery and study of exoplanets. The article "La région habitable de l'Univers" (The Habitable Region of the Universe) explains how astronomers are identifying planets outside our solar system that could potentially harbor life. The discovery of thirteen exoplanets within 150 light-years of Earth is presented as a major breakthrough. The concept of the "habitable zone" around stars is explained, where conditions might be suitable for life as we know it.
The Drake Equation
The famous Drake Equation, formulated by astronomer Frank Drake, is presented as a framework for estimating the number of communicative extraterrestrial civilizations in our galaxy. The equation considers factors such as the rate of star formation, the fraction of stars with planets, the number of habitable planets, and the lifespan of technological civilizations.
Hypotheses on Extraterrestrial Presence
Astronomers like Jean-Claude Ribes and Guy Monnet are cited for their hypotheses regarding the possibility of extraterrestrial visitors. They suggest that if humans can eventually travel to distant stars, it's plausible that advanced civilizations have already done so. Jean-Claude Ribes proposes that such visitors might reside discreetly within our solar system, perhaps in the asteroid belt, and their incursions could manifest as UFO sightings.
Challenges and Future Research
The article touches upon the difficulties in detecting extraterrestrial life, including the vast distances involved and the need for advanced technology. The search for "Earth-like" planets is a primary focus, with upcoming projects like the COROT satellite and the Infrared Space Interferometer aiming to detect and characterize such worlds. The possibility of finding ozone, a byproduct of biological activity, is highlighted as a potential indicator of life.
Scientific Perspectives on UFOs
Jean-Jacques Vélasco, head of SEPRA at CNES, shares his experience investigating UFO cases, noting that while many are explained, about 40% remain unidentified. He describes these phenomena as physical, sometimes detected by radar, and possessing unusual characteristics. The article emphasizes that while direct scientific connection between extraterrestrial life and UFOs is not yet established, the hypothesis cannot be dismissed.
The Russian Effort
An effort by Russian scientists to detect optical flashes from powerful lasers, potentially used for communication by extraterrestrials, is mentioned. Despite eighteen years of observation using a 6-meter telescope, no such signals have been detected.
The Search for Rocky Planets
Michel Mayor and Geoffrey Marcy are credited with discovering exoplanets, some of which are gas giants close to their stars. This phenomenon suggests that these planets may have migrated from farther out, potentially destroying smaller, rocky planets in the process. The search continues for rocky planets similar to Earth.
Recurring Themes and Editorial Stance
The magazine's stance is one of open-minded scientific inquiry. It advocates for the objective examination of UFO phenomena, moving beyond sensationalism and speculation towards evidence-based research. The recurring themes include the vastness of the universe, the probability of life beyond Earth, the technological challenges in detecting it, and the evolving role of science in exploring these profound questions. The editorial tone encourages a rational yet curious approach to the mysteries of the cosmos and potential extraterrestrial encounters.
