Radiowave Observations on the Lunar Surface of the photo-Electron Sheath instrument (ROLSES- 1) onboard the Intuitive Machines’ Odysseus lunar lander represents NASA’s first radio telescope on the Moon, and the […]
Technosignatures
Ringworlds And Dyson Spheres Can Be Stable
In his 1856 Adams Prize essay, James Clark Maxwell demonstrated that Saturn’s rings cannot be comprised of a uniform rigid body. This is a consequence of the two-body gravitational interaction […]
Earth Detecting Earth: At What Distance could Earth’s Constellation of Technosignatures be Detected with Present-day Technology?
The field of the Search for Extraterrestrial Intelligence (SETI) searches for “technosignatures” that could provide the first detection of life beyond Earth through the technology that an extraterrestrial intelligence (ETI) […]
Earth Detecting Earth
A research team led by Dr. Sofia Sheikh of the SETI Institute, in collaboration with the Characterizing Atmospheric Technosignatures project and the Penn State Extraterrestrial Intelligence Center, set out to […]
COSMIC’s Large-Scale Search for Technosignatures during the VLA sky Survey: Survey Description and First Results
Developing algorithms to search through data efficiently is a challenging part of searching for signs of technology beyond our solar system.
The Challenge of Detecting Remote Spectroscopic Signatures From Radionuclides
The characterization of exoplanetary atmospheres through transit spectra is becoming increasingly feasible, and technology for direct detection remains ongoing.
SETI In 2022
In this third installment of SETI in 20xx, we very briefly and subjectively review developments in SETI in 2022.
SETI Institute Starts First Low Frequency Search For Alien Technology In Distant Galaxies
The SETI Institute, the Berkeley SETI Research Center and the International Centre for Radio Astronomy Research announced a groundbreaking study using the Murchison Widefield Array (MWA) in Western Australia. Led […]
Geoscientists Dig Into Why We May Be Alone In The Milky Way (Tectonics)
New research by University of Texas at Dallas geoscientist Dr. Robert Stern and a colleague suggests a geological explanation for why conclusive evidence for advanced extraterrestrial (ET) civilizations has not […]
Searching the SN 1987A SETI Ellipsoid with TESS
The SETI Ellipsoid is a strategy for technosignature candidate selection which assumes that extraterrestrial civilizations who have observed a galactic-scale event — such as supernova 1987A — may use it […]
