Last week (Friday. Feb. 14th), the Breakthrough Listen Initiative released about 2 petabytes of optical and radio data that they have accumulated over the past four years. This is the second data release by the non-profit effort (as part of Breakthrough Initiatives) and the public is once again invited to search through the data for possible signs of extraterrestrial communications.Continue reading “SETI Researchers Release Petabytes of Data in the Search For Aliens”

Tonight we are very excited to welcome Dr. Kathryn Bywaters, Research Scientist at the SETI Insitute where she is currently working on the development of life-detection instrumentation for future space exploration. Additionally, she is investigating the nutrient constraints microbes would have on Mars as well as performing experiments in Mars analog environments.Continue reading “Weekly Space Hangout: November 20, 2019 – Kathryn Bywaters, Research Scientist at the SETI Insitute”
This week, the non-profit research organization Breakthrough Listen announced that it was entering into a partnership with scientists from the NASA Transiting Exoplanet Survey Satellite (TESS) mission. This new collaboration will direct the resources of the former with data and expertise of the latter to the search for extra-terrestrial intelligence (SETI) like never before!Continue reading “Breakthrough Listen and NASA Team Up to Look for Signs of Extra-Terrestrial Intelligence!”
As many of you are no doubt aware, our noble publisher, Fraser Cain, occasionally has the opportunity to sit down with some fellow great minds and discussion/debate issues that are relevant to space, exploration, and astronomy today. Most recently, this included an extended debate with noted author, futurists and Youtube sensation John Michael Godier.
The subject of this debate was the unresolved mystery that keeps more than a few astrophysicists awake at night. This is none other than the Fermi Paradox, the question that asks “Where are they?”Continue reading “Fraser and John Michael Godier Debate the Fermi Paradox”
In 2016, Russian-Israeli billionaire Yuri Milner launched Breakthrough Initiatives, a massive non-profit organization dedicated to the search for extra-terrestrial intelligence (SETI). A key part of their efforts to find evidence of intelligent life is Breakthrough Listen, a $100 million program that is currently conducting a survey of one million of the nearest stars and the 100 nearest galaxies.
In keeping with their commitment to making the results of their surveys available to the public, the Listen team recently submitted two papers to leading astrophysical journals. These papers describe the analysis of Listen’s first three years of radio observations which resulted in a petabyte of radio and optical data, the single largest release of SETI data in the history of the field.Continue reading “Want to Find Aliens? The Largest Dataset in the History of SETI has Been Released to the Public”
In 1960, famed theoretical physicist Freeman Dyson made a radical proposal. In a paper titled “Search for Artificial Stellar Sources of Infrared Radiation” he suggested that advanced extra-terrestrial intelligences (ETIs) could be found by looking for signs of artificial structures so large, they encompassed entire star systems (aka. megastructures). Since then, many scientists have come up with their own ideas for possible megastructures.
Like Dyson’s proposed Sphere, these ideas were suggested as a way of giving scientists engaged in the Search for Extra-Terrestrial Intelligence (SETI) something to look for. Adding to this fascinating field, Dr. Albert Jackson of the Houston-based technology company Triton Systems recently released a study where he proposed how an advanced ETI could use rely on a neutron star or black hole to focus neutrino beams to create a beacon.Continue reading “Advanced Civilizations Could be Communicating with Neutrino Beams.

During the 1940s, Hungarian-American scientist John von Neumann developed a mathematical theory for how machines could endlessly reproduce themselves. This work gave rise to the idea of “von Neumann probes“, a class of self-replicating interstellar probes (SRPs) that could be used to do everything from exploring the Universe to seeding it with life and intervening in species evolution.
Some have naturally suggested that this be a focus SETI research, which would entail looking for signs of self-replicating spacecraft in our galaxy. But as is always the case with proposals like these, the Fermi Paradox eventually reasserts itself by asking the age-old question – “Where is everybody?” If there are alien civilizations out there, why haven’t we found any evidence of their SRPs?Continue reading “Maybe Self-Replicating Robot Probes are Destroying Each Other. That’s Why We Don’t See Them”
In the course of looking for possible signs of Extra-Terrestrial Intelligence (ETI), scientists have had to do some really outside-of-the-box thinking. Since it is a foregone conclusion that many ETIs would be older and more technologically advanced than humanity, those engaged in the Search for Extra-Terrestrial Intelligence (SETI) have to consider what a more advanced species would be doing.
A particularly radical idea that has been suggested is that spacefaring civilizations could harness radiation emitted from black holes (Hawking radiation) to generate power. Building on this, Louis Crane – a mathematician from Kansas State University (KSU) – recently authored a study that suggests how surveys using gamma telescopes could find evidence of spacecraft powered by tiny artificial black holes.Continue reading “Gamma Ray Telescopes could Detect Starships Powered by Black Hole”
In 1961, famed astronomer Frank Drake created a formula for estimating the number of extra-terrestrial intelligences (ETIs) that could exist within our galaxy. Known as the “Drake Equation“, this formula demonstrated that even by the most conservative estimates, our galaxy was likely to host at least a few advanced civilizations at any given time. About a decade later, NASA officially kicked of its search for extra-terrestrial intelligence (SETI) program.
These efforts have experienced a major infusion of interest in recent decades thanks to the discovery of thousands of extrasolar planets. To address the possibility that life may exist out there, scientists are also relying on sophisticated tools to search for telltale indicators of biological processes (aka. biosignatures) and technological activity (technosignatures), which could indicate not only life but advanced intelligence.
