Is there life on Venus? (science video)
Researchers from Cardiff University and MIT just published a paper in Nature in which they claim to have found phosphine, a possible biosignature, in the clouds of Venus’ atmosphere. David Grinspoon, astrobiologist, and Nathalie Cabrol of the Carl Sagan Center at the SETI Institute, chat about the exciting new possibility of life on Venus.
No signs of alien technology in 10 million scanned star systems (science news).
Astronomers have just used the Murchison Widefield Array telescope to explore hundreds of times more broadly than any previous search for extraterrestrial life. The study, published in the Publications of the Astronomical Society of Australia, observed the sky around the Vela constellation. But in this part of the Universe at least, it appears other civilisations […]
The eerie silence? SETI discussion (video).
A technologically advanced extraterrestrial civilization could likely detect life on Earth if such beings exist. Life on Earth would be detectable in our planet’s atmospheric spectral lines for over a billion years. Most of our atmospheric oxygen is due to life, and can be observed over interstellar distances — across thousands of light-years. Over this […]
SETI expands hunt for alien life in the stars with Very Large Array (news).
Emerging technologies and new strategies are opening a new era in the Search for Extraterrestrial Intelligence … aka SETI. New discovery capabilities, along with the rapidly-expanding number of known planets orbiting stars other than the Sun, are spurring innovative approaches by both government and private organisations, according to a panel of experts speaking at a […]
Astronomers to sweep, while Pentagon leaks (UFO news).
Two interesting stories drop across the SFcrowsnest desk thanks to our national newspapers. In the first story, astronomers are now sweeping the entire sky for signs of extraterrestrial life as part of a collaboration between a privately-funded firm and the New Mexico Observatory. In the second story, the Pentagon’s classified UFO program run out of […]
The Drake Equation examined (science video).
The Drake equation provides a rough estimate of the number of civilisations in our galaxy … so where is ET and why have we yet to come across them? In this 35 minute science video, Ian Crawford, professor of planetary science and astrobiology at Birkbeck, University of London, examines what known variables we can now […]
Why intelligent life could be hiding out there in the galaxy (and probably is) (science documentary).
Answering the question of are we alone has turned out to be a bit more difficult than was originally envisioned when SETI first began decades ago. At first it was a matter of looking for giant omni-directional beacons blasting out high energy messages, much like what we saw in the movie contact. But as we’ve […]
Artificial intelligence loves strange alien galaxy fast radio bursts. True.
Artificial intelligence is invading many fields, most recently astronomy and the search for intelligent life in the universe, or SETI. Researchers at Breakthrough Listen, a SETI project led by the University of California, Berkeley, have now used machine learning to discover 72 new fast radio bursts from a mysterious source some 3 billion light years […]
E.T. just ain’t there, says new research.
Sensitive new telescopes now permit astronomers to detect waste heat expected to be a signature of advanced alien civilisations that can harness enormous energies on the scale of the stellar output of their own galaxy. Now, Professor Michael Garrett (ASTRON General & Scientific Director) has used radio observations of candidate galaxies to show that such […]
