started his writing career as an investigative journalist, covering intelligence activities and politics.In 1995, he was a co-founder of Frontier 2000(later called Frontier Magazine), a periodical with a circulation centered primarily in the Benelux countries. In 1999, he served as the primary researcher for The Stargate Conspiracy, a book about ancient Egypt and the degree to which its history serves as a continuing influence on contemporary politics and politicians.
Coppens' second book, The Canopus Revelation (2004), questioned the assumption that ancient Egyptians associated their god Osiris with the constellation of Orion. Instead he proposed Canopus, the second brightest star in the night-time sky. He appeared at Quest Conference 2005 to give a presentation on this idea.
In Servants of the Grail (2009), Coppens suggested real-life counterparts for the characters in Chretein de Troyes Perceval, the story of the Grail. These included the identification of Rotrou III, Count of the Perche with Perceval. Also in 2009, he contributed a chapter to Ancient Code: Are You Ready for the Real 2012?, entitled "Ancient Inroads Towards a New Age".
From 2010 to 2012, Coppens was a frequent contributor to the History Channel's Ancient Aliens series. Nigerian journalist J.K. Obatala, writing about a month after Coppens' death, described him as an "ancient alien buff."Obatala credited Coppens with helping to debunk a claim that the Dogon Ayantu (spiritual leaders) of Mali had astronomical knowledge they could only have obtained from visitors from Sirius – in an article entitled "Dogon Shame."
In October 2012, he was a featured presenter at Intrepid Magazine's Paradigm Symposium.
A eulogy for Coppens, published in Intrepid's January print edition, included a quotation from Coppens' final post to his personal blog: "I was diagnosed with an extremely rare case of cancer, angiosarcoma, which affects less than 200 people in the U.S. (each year). Each case is almost by default unique… and so I found that the man who normally studies anomalies, has become a medical enigma a well.”Roughly a fortnight later, Coppens died.
