From the 300-light-years-away department: An invisible molecular cloud that could shed light on how stars and planets form has been detected surprisingly close to Earth. From a report: Named Eos after the Greek goddess of the dawn, the cloud of gas would appear huge in the night sky if visible to the naked eye. It measures roughly 40 moons in width and has a weight about 3,400 times the mass of the sun, researchers reported in a study published Monday in the journal Nature Astronomy.
"In astronomy, seeing the previously unseen usually means peering deeper with ever more sensitive telescopes -- detecting those smaller planets ... those more distant galaxies," said study coauthor Thomas Haworth, an astrophysicist at Queen Mary University of London. "This thing was pretty much in our cosmic backyard, and we've just missed it," he added. Molecular clouds are composed of gas and dust from which hydrogen and carbon monoxide molecules can form. Dense clumps within these clouds can collapse to form young stars. The article clarifies that Eos is 300 light-years away, which to be sure, is closer than any of the molecular clouds that we've known about previously.

From the leave-the-kitty-alone department: A thought experiment involving a cat trapped in a steel box with a potentially lethal device, first proposed by physicist Erwin Schrodinger in 1935, remains at the center of scientific and philosophical debate as it marks its 90th anniversary.
The paradox, initially published in a technical review of quantum mechanics, presented a scenario where a cat could theoretically exist in a superposition of states -- both alive and dead simultaneously -- until observed, highlighting profound questions about quantum reality. "Schrodinger understood that under no circumstances could his cat be considered to be both alive and dead at the same time," science writer Jim Baggott noted in a recently published essay. Baggott co-authored "Quantum Drama: From the Bohr-Einstein Debate to the Riddle of Entanglement" in 2024.
The thought experiment gained cultural traction largely through science fiction writer Ursula Le Guin's 1974 short story "Schrodinger's Cat," which wrestled with the paradox's philosophical implications. This sparked widespread appearances across literature, film, and television.
The paradox continues to divide physicists between those accepting quantum mechanics as a mathematical framework for prediction and others, like Einstein and Schrodinger himself, who considered the theory fundamentally incomplete.
