Will Artificial Intelligence Make the First Discovery of “Alien” Technosignatures? (The Galaxy Report)
Today’s stories include New map of all the matter in the universe to Can cosmology untangle the universe’s most elusive mysteries? and much more
Will an AI be the first to discover alien life?--SETI, the search for extraterrestrial intelligence, is deploying machine-learning algorithms that filter out Earthly interference and spot signals humans might miss, r.eports Nature.com. "The biggest challenge for us in looking for SETI signals is not at this point getting the data,” says Sofia Sheikh, an astronomer at the SETI Institute. “The difficult part is differentiating signals from human or Earth technology from the kind of signals we’d be looking for from technology somewhere else out in the Galaxy.”
New map of all the matter in the universe, reports the University of Chicago. "Among other findings, the analysis indicates that matter is not as "clumpy" as we would expect based on our current best model of the universe, which adds to a body of evidence that there may be something missing from our existing standard model of the universe."
Can cosmology untangle the universe’s most elusive mysteries?--From the Big Bang to dark energy, knowledge of the cosmos has sped up in the past century — but big questions linger, reports Knowable.com
Watch distant worlds orbit around their sun--Stunning new time lapse video shows 12 years of exoplanets orbiting their star, reports Northwestern. "Using observations collected over the past 12 years, Northwestern University astrophysicist Jason Wang has assembled a stunning time lapse video of the family of four planets — each more massive than Jupiter — orbiting their star. The video gives viewers an unprecedented glimpse into planetary motion."
Gigantic 'alien' comet spotted heading straight for the sun, reports Ben Turner for Live Science. Scientists think it may have come from another solar system.
AI is helping us search for intelligent alien life – and we’ve found 8 strange new signals, reports Danny C. Price, Senior research fellow, Curtin University for The Conversation. "This machine-learning approach presents itself as a leading solution in accelerating SETI and other transient research into the age of data-driven astronomy.
Largest asteroid ever to hit Earth was twice as big as the rock that killed off the dinosaurs, reports Harry Baker for Live Science. The destructive space rock was somewhere between 12.4 and 15.5 miles wide.
Astronomers Find 25 Hugely Powerful Fast Radio Bursts That Keep Repeating, reports Matt Willams via Science Alert. "While some are believed to be caused by neutron stars and black holes (attributable to the high-energy density of their surroundings), others continue to defy classification. Because of this, other theories persist, ranging from pulsars and magnetars to GRBs and extraterrestrial communications."
