RIP Dinosaurs, who were killed by two asteroids not just one

A study published in Earth and Planetary Science Letters adds a new wrinkle to the asteroid assumption by suggesting that the dinos may have had to contend with not one, but two deadly balls of flying space rock. Titled “Morphology and population of binary asteroid impact craters,” the study was lead by Katarina Miljkovic from the Institute of Earth Physics in Paris.

A newly discovered galactic structure is so large that it means one of our basic assumptions about the nature of the universe could be wrong.

The Week has a great roundup of predicted apocalypses that never came to pass. Our favorite:



Halley’s Comet, 1910
What was predicted: When Halley’s Comet reappeared in 1910, the Chicago Yerkes Observatory made the poorly calculated decision to announce that it had detected a poisonous gas in the comet’s tail. The New York Times added fuel to the fire by quoting a French astronomer as saying this gas “would impregnate that atmosphere and possibly snuff out all life on the planet.” Panic ensued, gas masks were purchased, and people began loading up on “comet pills,” [emphasis ours] which promised to counter the effects of the noxious gas. In an attempt to keep the fumes at bay, homeowners placed pieces of paper over their locks.
What actually happened: The planet remained undisturbed. Once the comet had passed, The Chicago Tribune announced to readers, “We’re still here.”

NASA’s vision for space exploration circa 1975

In the summer of 1975, when space exploration was less than two decades old, NASA Ames Research Center and Stanford University held a space settlement design summit, known as the 1975 NASA Summer Study, that envisioned what life in space might look like, with a focus on orbiting spaceships. The result was a document called “Space settlements: A design study.”
