What Space Object ‘Oumuamua Says About How Science Works

The space object, thought by at least one famed astronomer to be an ET lightsail, prompts thoughts about how scientists decide what to believe

The subtitle of Matthew Bothwell’s wrap-up on ‘Oumuamua is most informative: An alien-made artefact or just interstellar debris? What ʻOumuamua says about how science works when data is scarce. At least one astronomer, Harvard’s Avi Loeb, insisted that ‘Oumuamua must be an “extraterrestrial light sail.” And few suggested that that couldn’t possibly be true. Right. What do we do when we are not sure? Bothwell, author of the forthcoming Invisible Universe, offers some thoughts. W all imagine ET in our own image: Victorians of the late 19th century, living in the era of ambitious engineering, looked at Mars and saw globe-spanning canals – evidence, they believed, of a grand industrial civilisation mirroring their own. In the Cold War 1960s, as…

SETI’s Seth Shostak Explains the New Galileo Project To Find ET

Controversial Harvard astronomer Avi Loeb has put together a private funding package to search for alien life

The Galileo Project, formed in response to the recent release report on Unidentified Aerial Phenomena (UAP), proposes to look “systematically, scientifically and transparently” for evidence of ET. The report noted that a number of observed phenomena remain unexplained. SETI’s Seth Shostak explains: Avi Loeb, a Harvard astrophysicist who doesn’t hesitate to swim in the shark-infested waters of controversy, is proposing a major effort to find aliens in our solar system, perhaps even in our airspace. He has raised $1.7 million in private funding to launch something he calls the Galileo Project, an initiative to bring the rigor of experimental science to ufology. Loeb’s plan is to use a telescope now under construction, the Vera C. Rubin Observatory, to study interstellar…

SETI Director Warns: Those Aliens Could Be Malevolent

Harvard astronomer agrees: We’ve sent a lot of signals in recent years; they may have got them. But now what?

As the Mars Rover Perseverance bumps around looking for fossil bacteria and such, many students of possible ET life are becoming surprisingly cautious about what it might mean: “We have no reason to believe that technological advancement and altruism or morality are somehow linked,” SETI researcher Andrew Siemion told Inverse. “There probably are malevolent civilizations elsewhere in the universe so that’s certainly something that we should consider as we continue to explore the universe.” Siemion, who’s the director of the Berkeley SETI Research Center and principal of the alien-hunting Breakthrough Listen project, is invoking a tension at the heart of any project searching for alien life. Successfully finding it would change the world — but there’s also no guarantee humanity…

Astrobiologist Cautions Against Jumping the Gun in Spotting ET

Scientists he says, are cautious with good reason. There are many weird natural phenomena like Oumuamua out there.

At Nautilus, astrophysicist (and astrobiologist) Caleb A. Scharf offers some sobering reflections on the diligent search for extraterrestrial intelligences (ET) in recent decades: Despite this effort, there has been no evidence to date of extraterrestrial life. But that lack of evidence is not because the scientific enterprise is uniformly conservative, rigid, and close-minded, as implied by [astronomer Avi] Loeb and uncritically echoed by some columnists. It’s because no discovery or event has risen to the level where it is inexplicable in any other way. Could greater funding and support change that story? Perhaps, but the same could be said for almost any other ambitious scientific enterprise, and the answer cannot be known beforehand. Caleb Scharf, “The Alien-Haunted World” at Nautilus…
