From explaining unusual features on #Mars and studying #meteor airbursts in Earth’s atmosphere to advancing new ways of detecting #technosignatures, March’s stories reflect how we are refining our understanding of both nearby and distant worlds.

This is the cover of The Worlds Within Magazine where my latest story, my 12th published one, appears.

My new #sciencefiction story "Who Speaks for Earth" was just published in The Worlds Within magazine: bit.ly/speaksforEarth It's about a Congressional hearing to investigate the aftermath of receiving an alien message. #SETI #astronomy #hardSF #space #technosignatures #aliens #scifi #sfbyscientists

SETI Analyses Flag 92 Radio Candidates and Three Laser-Like Optical Anomalies, Prompting Rethink of Search Strategies The Angry Astronaut reviews new technosignature research, highlighting 92 radio candidates from the SETI@home archive and three tiered optical anomalies identified in ESO HARPS data. The presentation also examines evidence that stellar plasma turbulence could smear narrowband transmissions, potentially masking genuine extraterrestrial signals and motivating broader search methods.

New SETI analyses surface 92 radio candidates and three laser-like optical anomalies - plus evidence stellar plasma turbulence could smear narrowband transmissions. Results push for broader technosignature search strategies. #SETI #technosignatures #astronomy

Astrobiologist Outlines Case for Bringing UAP Into SETI’s Research Agenda At the Sol Foundation Symposium, astrobiologist Dr. Jacob Haqq-Misra argued that the scientific search for technosignatures should explicitly include Unidentified Anomalous Phenomena and solar system artifact searches. He reviewed the sparse record of such searches, traced cultural and institutional barriers within SETI, and proposed practical frameworks and missions to close the gap.

Adam Frank Weighs Technosignatures, UAP Evidence Standards, and the Stakes for Science, Space, and Climate Astrophysicist Adam Frank discusses the scientific search for technosignatures, the evidentiary bar for UAP claims, and how civilizations imprint themselves on planets. The wide-ranging conversation spans exoplanet science, the Silurian hypothesis, limits on interstellar travel, AI risks, lunar and Mars ambitions, and why climate science and public trust in evidence-based inquiry remain pivotal.

I've just ordered this (paperback version): "The Search for Extraterrestrial Intelligence - Theory and Practice" by @astrowright.bsky.social @iop.org @ioppublishing.bsky.social #technosignatures #biosignatures #SETI #astrobiology 🔭🧪⚛️

The Search for Alien Artifacts Is Coming Into Focus From surveys of the pre-Sputnik skies to analysis of interstellar visitors, scientists are rethinking how and where to look for physical traces of alien technology.

I propose ​a possible #FermiParadox answer:

​Life is common enough to exist.

Intelligence is rare enough to feel alone.

Cool paper David!
“Civilizationovae” may be orders of mag easier to detect, sadly (Planets with “fevers”?) 1st examples in astronomy, some times used as prototypes, end up being Gott’s “million-pound penguins” that skew stats. But it gives hope #technosignatures may be easier to detect via outliers!
