Introduction
Jack Pettigrew’s work on the Min Min lights is important because it shifted the debate from folklore and anecdotal mystery towards a testable scientific explanation. Rather than dismissing witnesses, the University of Queensland neuroscientist and vision researcher treated the lights as a real visual phenomenon that could be studied in the field. His 2003 paper in Clinical and Experimental Optometry became the most influential scientific account of Min Min lights in western Queensland, arguing that many sightings could be explained by a rare atmospheric mirage known as a Fata Morgana.

For Queensland’s UFO and mystery-light history, Pettigrew’s contribution matters because he did not rely solely on theory. He based his explanation on direct observations, interviews with witnesses and a field demonstration in the Channel Country. The strength of his work lies less in proving the source of every reported light and more in showing that a supposedly supernatural or unexplained phenomenon could be reproduced through known optical processes.

What Pettigrew observed in western Queensland
Pettigrew first encountered Min Min lights while conducting unrelated field research in western Queensland. He was studying the rare letter-winged kite and spending long periods in remote night-time conditions across the Diamantina and Channel Country regions. During this work he repeatedly heard local accounts of strange lights and eventually observed them himself.

What interested him was not merely the appearance of the lights but their reported behaviour. Witnesses frequently described lights that seemed to:
- Hover above the horizon.
- Follow vehicles for long distances.
- Retreat when approached.
- Change colour or brightness.
- Remain visible despite efforts to identify their source. [News]news.uq.edu.auNews UQ scientist unlocks secret of Min Min lightsUQ scientist unlocks secret of Min Min lights - UQ News…
Pettigrew noted that these reports were often coming from experienced outback residents rather than casual tourists. Some witnesses had spent decades working in remote environments and were familiar with ordinary lights, planets and atmospheric conditions. This made simple explanations such as misidentifying Venus or a nearby vehicle less persuasive on their own.

His approach was therefore to ask whether unusual atmospheric conditions could create a genuinely strange visual experience without requiring an unknown physical object. [Wiley Online Library]onlinelibrary.wiley.comj.1444 0938.2003.tb03069.xJohn D Pettigrew BSc(Med) MSc MBBS FRS…Read more…
How the field demonstration supported the mirage model
The centrepiece of Pettigrew’s case was not witness testimony but a practical demonstration.
His hypothesis proposed that Min Min lights are often distant light sources carried over the horizon by a temperature inversion. Under these conditions, cold dense air lies close to the ground while warmer air sits above it. The resulting refractive layers bend light in unusual ways, producing a type of inverted mirage known as a Fata Morgana. [Wiley Online Library+2PubMed]onlinelibrary.wiley.comj.1444 0938.2003.tb03069.xJohn D Pettigrew BSc(Med) MSc MBBS FRS…Read more…
According to Pettigrew, this process can transport light from sources tens or even hundreds of kilometres away, making them appear as isolated glowing objects with no obvious origin. Because the observer sees only a single displaced light rather than the landscape around it, judging distance and movement becomes extremely difficult.

One of his best-known field tests involved using vehicle headlights as a controlled light source. In a reported experiment, Pettigrew drove approximately 10 kilometres from a campsite and switched his headlights on and off while maintaining radio contact with observers. The observers reported seeing a hovering light above the horizon that changed colour and appearance. When the headlights were extinguished, the apparent Min Min light disappeared; when they were turned on again, the light returned.

Pettigrew also argued that geometric analysis sometimes allowed him to trace apparent Min Min lights back to distant roads and vehicle traffic far beyond the visible horizon. In some cases he suggested that lights seen as mysterious objects were actually truck headlights at extraordinary distances, made visible by atmospheric refraction.

These demonstrations were significant because they transformed the discussion from “Could a mirage do this?” to “Here is a mechanism producing similar effects under field conditions.” [Wiley Online Library]onlinelibrary.wiley.comj.1444 0938.2003.tb03069.xJohn D Pettigrew BSc(Med) MSc MBBS FRS…Read more…
Why the explanation fit famous Min Min behaviours
Pettigrew’s model addressed several features that had long encouraged UFO-style interpretations.
The apparent tendency of Min Min lights to follow travellers is one example. If the light source is extremely distant, changes in the observer’s position can create little apparent movement against the background. The result can be a light that seems to accompany a vehicle for many kilometres even though the source remains fixed. [Wiley Online Library]onlinelibrary.wiley.comj.1444 0938.2003.tb03069.xJohn D Pettigrew BSc(Med) MSc MBBS FRS…Read more…
The model also helps explain why observers often fail to reach the light. If the visible glow is a refracted image rather than a nearby object, driving towards it does not necessarily reduce the distance in the expected way. The light can appear to retreat, shift position or vanish as atmospheric conditions change. [Wiley Online Library]onlinelibrary.wiley.comj.1444 0938.2003.tb03069.xJohn D Pettigrew BSc(Med) MSc MBBS FRS…Read more…
Colour changes are another point. Refraction through multiple air layers can distort and alter the appearance of distant lights, especially when they are viewed near the horizon. Witness descriptions of red, yellow, green or white lights are therefore not inconsistent with a mirage-based explanation.

Why scientific reproduction does not solve every story
Although Pettigrew’s work remains the leading scientific explanation for many Queensland Min Min reports, it does not automatically resolve every historical account.
First, his paper argued that many strange properties of the lights are explicable through atmospheric optics and human perception under low-information conditions. It did not claim that every reported sighting had been individually investigated and identified. [Wiley Online Library]onlinelibrary.wiley.comj.1444 0938.2003.tb03069.xJohn D Pettigrew BSc(Med) MSc MBBS FRS…Read more…
Second, some reports pre-date modern vehicle traffic. Pettigrew suggested that earlier sightings could have involved campfires or other natural light sources rather than headlights, but historical cases are often too poorly documented to test directly. [Wiley Online Library]onlinelibrary.wiley.comj.1444 0938.2003.tb03069.xJohn D Pettigrew BSc(Med) MSc MBBS FRS…Read more…
Third, atmospheric conditions suitable for strong Fata Morgana effects are variable. Even supporters of the mirage model acknowledge that reproducing the exact circumstances of a particular sighting can be difficult. The explanation is strongest as a mechanism capable of producing Min Min-like experiences rather than as a complete reconstruction of every encounter. [Wiley Online Library]onlinelibrary.wiley.comj.1444 0938.2003.tb03069.xJohn D Pettigrew BSc(Med) MSc MBBS FRS…Read more…
For that reason, Pettigrew’s work is best understood as a major advance in understanding the phenomenon rather than a final verdict on every story associated with the Min Min tradition.
Why Pettigrew’s evidence remains influential
Within Queensland’s history of unusual aerial and light phenomena, Pettigrew’s study stands out because it combined field observation with a specific physical mechanism. Many mystery-light explanations rely mainly on speculation or retrospective interpretation. Pettigrew instead attempted to observe the phenomenon directly, identify the environmental conditions involved and demonstrate a comparable effect using known light sources. [Wiley Online Library]onlinelibrary.wiley.comj.1444 0938.2003.tb03069.xJohn D Pettigrew BSc(Med) MSc MBBS FRS…Read more…
As a result, his 2003 paper became the principal scientific reference for discussions of Min Min lights. Even critics and alternative theorists generally begin by addressing his Fata Morgana model because it remains the most detailed evidence-based explanation produced for the phenomenon. [Wiley Online Library]onlinelibrary.wiley.comj.1444 0938.2003.tb03069.xJohn D Pettigrew BSc(Med) MSc MBBS FRS…Read more…
In the broader context of Queensland UFO history, Pettigrew’s research is a reminder that some of the state’s most famous “unexplained lights” may owe as much to atmospheric optics and human perception as to any unknown object. His field evidence did not eliminate the mystery entirely, but it gave investigators a concrete, testable framework that many earlier explanations lacked.
