Even geophysicist Mika McKinnon, one of the science consultants for a $140 million disaster movie called “Moonfall,” admits that the moon-crashing tale is ridiculously exuberant. But what’s wrong with that? “A movie is… Read More
Could extraterrestrial civilizations leave their fingerprints as chlorofluorocarbons in planetary atmospheres, or the waste heat generated by industrial processes, or artificial bursts of neutrinos or gravitational waves? That’s what a… Read More
It’s been a quarter-century since Congress cut off NASA funding for the search for extraterrestrial intelligence, or SETI, but now the space agency is revisiting the topic under another name:… Read More
Alien megaspheres … rockets powered by nuclear bombs … freeze-dried life in outer space: These are just some of the ideas that have flowered in the brain of physicist Freeman… Read More
The astronomers who once speculated that an alien megastructure might be responsible for the weirdly fluctuating light from a distant star have now fully ruled out that way-out explanation. Their… Read More
Are aliens building a huge energy-generating megastructure around a weirdly dimming star? That way-out hypothesis has suffered another blow, thanks to a study that draws upon infrared as well as… Read More
Tabby’s Star – also known as KIC 8462852 or the “alien megastructure” star – is at it again. And this time the world is watching. The star in the constellation Cygnus has… Read More
That mysterious “alien megastructure” star is still a mystery, but the most plausible explanations appear to be dense patches of interstellar gas or dust that just happened to pass in… Read More
It’s been almost a year since astronomers first speculated that a strangely dimming star called KIC 8462852 might harbor an alien megastructure, and newly reported observations are making the case… Read More
The SETI Institute is shifting the focus of its search for extraterrestrial intelligence to places that could harbor life that’s not as we know it: 20,000 red-dwarf star systems. “Red… Read More
He’s not saying it’s aliens – but an astronomer has raised new questions about KIC 8462852, the strange star that stirred up a debate about “alien megastructures” months ago. In a paper… Read More
For months, scientists have puzzled over weirdly bright spots of material shining on the asteroid Ceres, but now they say the spots are probably made of salty ice. That determination, based on… Read More
Recent infrared observations of a star that once showed a pattern of weird dimming have turned up no anomalous readings, astronomers say – and that supports the view that a comet blitz… Read More
The SETI Institute says it hasn’t detected any alien radio signals coming from a star whose light seems to be dimming in a weird way, but it’s too early to determine… Read More
