Starshot Is a Success: Part I
https://www.centauri-dreams.org/2026/03/03/starshot-is-a-success-part-i/
Published: March 3, 2026 16:40
The fortunes of Breakthrough Starshot have been the subject of so much discussion not only in comments in these pages but in backchannel emails that it is with relief that I turn to Jim Benford’s analysis of a project that has done significant work on…
The Language of Contact

How we think intersects with the language we think in. Consider the verb in classical Greek, a linguistic tool so complex that it surely allows shadings of thought that are the stuff of finely tuned philosophy. But are the thoughts in our texts genuinely…
Propulsion Options for the Solar Gravitational Lens Mission

A mission to the Sun’s gravity focus – or more precisely, the focal ‘line’ we might begin to use at around 650 AU – is never far from my mind. Any interstellar mission we might launch within the next thirty years or so (think Breakthrough Starshot, about…
A Relativistic Explanation for the Dearth of Circumbinary Planets

Published: February 11, 2026 18:33
Planets orbiting two stars have been found, but not all that many of them. We’re talking here about a planet that orbits both stars of a close binary system, and thus far, although we’ve confirmed over 6,000 exoplanets, we’ve only found 14 of them in this…
A New Tool for Exoplanet Detection and Characterization

It’s been apparent for a long time that far more astronomical data exist than anyone has had time to examine thoroughly. That’s a reassuring thought, given the uses to which we can put these resources. Ponder such programs as Digital Access to a Sky…
Holography: Shaping a Diffractive Sail
https://api.follow.it/track-rss-story-click/v3/jGd80SoQARV3jdvB41WeYW6xRNJzdXYn
Published: January 28, 2026 13:36
One result of the Breakthrough Starshot effort has been an intense examination of sail stability under a laser beam. The issue is critical, for a small sail under a powerful beam for only a few minutes must not only survive the acceleration but follow a…

The approaching storm will almost certainly cause power outages that will make it impossible to post here. If this occurs, you can be sure that I’ll get any incoming messages posted as soon as I can get back online. Please continue to post comments as…
Cellular Cosmic Isolation: When the Universe Seeds Life but Civilizations Stay Silent

So many answers to the Fermi question have been offered that we have a veritable bestiary of solutions, each trying to explain why we have yet to encounter extraterrestrials. I like Leo Szilard’s answer the best: “They are among us, and we call them…
Pandora: Exoplanets at Multiple Wavelengths

Sometimes we forget how overloaded our observatories are, both in space and on the ground. Why not, for example, use the James Webb Space Telescope to dig even further into TRAPPIST-1’s seven planets, or examine that most tantalizing Earth-mass planet…
Explaining Cloud-9: A Celestial Object Like No Other

Published: January 7, 2026 12:55
Some three years ago, the Five-Hundred Meter Aperture Spherical Telescope (FAST) in Guizhou, China discovered a gas agglomeration that was later dubbed Cloud-9. It’s a cute name, though unintentionally so, as this particular cloud is simply the ninth thus…

Will 2026 be the year we detect life elsewhere in the universe? The odds seem against it, barring a spectacular find on Mars or an even more spectacular SETI detection that leaves no doubt of its nature. Otherwise, this new year will continue to see us…
