Two massive asteroids, the size of a 40-story building are approaching our planet this weekend and are expected to fly past Earth safely.

BILLIONS OF YEARS FROM NOW, the night sky will glow with stars, dust, and gas from two galaxies: the Milky Way, in which we live, and the encroaching Andromeda Galaxy (M31). Astronomy by Lynette Cook

Our galaxy, the Milky Way, is colliding with its nearest large neighbor, the Andromeda Galaxy (M31). The merger will change the structure of both galaxies billions of years from now, resulting in a new arrangement of stars known as Milkomeda (“milk-AHM-mee-da”). The merging will significantly change the night sky. But into what?

The Milky Way’s thin disk of stars and gas is currently visible as a nebulous band arching over the summer sky. As Andromeda travels across the Milky Way, a second lane of stars will join the one that is currently visible in the night sky. The stars will no longer be limited to two narrow lanes after the final merger, but will instead scatter throughout the entire sky.

The chance of someone being killed by space junk falling from the sky may seem ridiculously tiny. After all, nobody has yet died from such an accident, though there have been instances of injury and damage to property. But given that we are launching an increasing number of satellites, rockets, and probes into space, do we need to start taking the risk more seriously?

A new study, published in Nature Astronomy, has estimated the chance of causalities from falling rocket parts over the next ten years.

Every minute of every day, debris rains down on us from space – a hazard we are almost completely unaware of. The microscopic particles from asteroids and comets patter down through the atmosphere to settle unnoticed on the Earth’s surface – adding up to around 40,000 tonnes of dust each year.

Artificial Intelligence has ushered the advancement of several disciplines throughout the years. But could it ever discover a new form of physics?

A group of roboticists from Columbia University wanted to exploit the vast potential of AI and find out if it can ever find an “alternative physics.”

Ever wanted to play first-person shooters on a monochrome graphing calculator screen? Well now you can! Or rather, you could for over a decade but I’m just now making a video on how to, ha.

Human-like temporal variability in movements is a powerful hint that humans use to ascribe humanness to robots.

A team of researchers at the University of Geneva has found that ketamine is unlikely to be addictive to people who use it for extended periods of time. In their paper published in the journal Nature, the group describes their study of the impact of the synthetic compound on the brains of mice and what they learned about its impact on different brain regions. Rianne Campbell and Mary Kay Lobo, with the University of Maryland School of Medicine have published a News and Views piece in the same journal issue outlining the work done by the team in Switzerland.

In recent years, more vehicles include partially autonomous driving features, such as blind spot detectors, automatic braking and lane sensing, which are said to increase safety. However, a recent study by researchers from The University of Texas at Austin finds that some of that safety benefit may be offset by people driving more, thereby clogging up roads and exposing themselves to more potential crashes.

The study, published recently in Transportation Research Part A—Policy and Practice, found that drivers with one or more of these autonomous features reported higher miles traveled than those of similar profiles who didn’t have them. This is important, because miles traveled is one of the most—if not the most—significant predictor of crashes. The more you drive, the more likely you are to crash.

“What we showed, without any ambiguity in our results, is that after embracing autonomous features, people tend to drive more,” said Chandra Bhat, one of the authors on the project and professor in the Cockrell School of Engineering’s Department of Civil, Architectural and Environmental Engineering. “There are certainly engineering benefits to these safety features, but they are offset to a good extent because people are driving more and exposed more.”
