It's no exaggeration to say that without Greg Matloff, there would have been no Centauri Dreams. After reading his The Starflight Handbook (Wiley, 1989) and returning to it for years, I began working on my own volume in 2001. Research for that book would reveal...

StarSearch: Our Hunt for a New Home World
His interest fired by an interview with interstellar researcher Greg Matloff, Dale Tarnowieski became fascinated with the human future in deep space. One result is the piece that follows, an essay that feeds directly into a recent wish of mine. I had been struck by...
Space Habitats Beyond LEO: A Short Step Towards the Stars
Building a space infrastructure is doubtless a prerequisite for interstellar flight. But the questions we need to answer in the near-term are vital. Even to get to Mars, we subject our astronauts to radiation and prolonged weightlessness. For that matter, can humans...
Star Consciousness: An Alternative to Dark Matter
by Dr. Gregory L. Matloff Gregory Matloff is a major figure in what might be called the 'interstellar movement,' the continuing effort to analyze our prospects for travel to the stars. Greg is Emeritus Associate Professor and Adjunct Associate Professor in the...
Worldships: A Interview with Greg Matloff
The first conference devoted solely to worldships takes place today in London at the headquarters of the British Interplanetary Society. It seemed a good time to check in with Gregory Matloff, a man I described when writing Centauri Dreams (the book) as the...
Space Butterfly: A Living Star Probe
Browsing through the correspondence that makes up Freeman Dyson’s wonderful Maker of Patterns: An Autobiography Through Letters (Liveright, 2018), I came across this missive, describing to his parents in 1958 why space exploration occupied his time at General Atomic,...
How to Explain Unusual Stellar Acceleration?
Anomalies in our models are productive. Often they can be explained by errors in analysis or sometimes systematic issues with equipment. In any case, they force us to examine assumptions and suggest hypotheses to explain them, as in the case of the unusual...
Probing Parenago: A Dialogue on Stellar Discontinuity
The publication of a paper called "New Features of Parenago's Discontinuity from Gaia DR1 Data" by V. V. Vityazev and colleagues brought us a new look at an unusual observation. Parenago's Discontinuity refers to the fact that red, cooler stars move faster in the...
Probing Ultrahot Jupiters
Speaking of getting really, really close to a star, as we were yesterday in our discussion of the Parker Solar Probe, I couldn’t help but turn to new computer models of the ‘ultrahot Jupiter’ WASP-121b. I still find it delightful that the earliest exoplanet detections...
Interplanetary Exploration: Application of the Solar Sail and Falcon Heavy
Gregory Matloff’s contributions to interstellar studies need scant introduction, given their significance to solar-and beamed sail development for decades, and their visibility through books like The Starflight Handbook (1989) and Deep Space Probes (2005). A quick...
