A NASA rover has captured incredible footage of a “dust devil” sweeping across the surface of Mars. To many on Earth, dust devils are known to form vertical columns of particles and hot air when the weather is particularly warm. But, astronomers have now observed a dust devil forming on Mars and it was absolutely huge, reaching an astounding 1.2 miles high. Images of the phenomenon were captured by NASA's Perseverance rover, which made its way to the Red Planet on 30 July 2020 and landed in February 2021. The machine’s cameras captured the plume of air and particles moving from east to west, travelling at a speed of around 12 miles per hour at Thorofare Ridge, on the western rim of the planet’s Jezero Crater, on 30 August 2023. The rover was located around 2.5 miles from the passing dust whirlwind when it captured the incredible scene in a series of photographs. NASA used the image data received from Perseverance to create a moving image made up of 21 frames taken four seconds apart, sped up 20 times. A NASA blog post about the phenomenon explained: “Using data from the imagery, mission scientists determined that the dust devil was about 2.5 miles (4 kilometres) away, at a location nicknamed ‘Thorofare Ridge,’ and moving east to west at a clip of about 12 mph (19 kph). “They calculated its width to be about 200 feet (60 meters). While only the bottom 387 feet (118 meters) of the swirling vortex are visible in the camera frame, scientists used the dust devil's shadow to estimate its full height at about 1.2 miles (2 kilometres).” It comes after alien enthusiasts were given a new reason to get excited about potential life on Mars, after scientists found cracked mud on the Red Planet.

Ever wondered how optical illusions actually work? Wonder no more. A new study by University of Exeter visual ecologist Jolyon Troscianko, and neuroscientist Daniel Osorio from the University of Sussex in the UK has weighed in on the debate over whether we perceive things weirdly because of certain errors in the ways our brain processes colour, shade, and shape or because of our eye's function or the brain's neurological wiring. They reckon it is all in the eyes. The pair found ways our visual neurons – cells that process information coming in from the eyes – work, showing how they can affect our perception of patterns on different scales. "Our eyes send messages to the brain by making neurons fire faster or slower," said Troscianko. "However, there's a limit to how quickly they can fire, and previous research hasn't considered how the limit might affect the ways we see colour."

"Our model shows how neurons with such limited contrast bandwidth can combine their signals to allow us to see these enormous contrasts, but the information is compressed – resulting in visual illusions," said Troscianko. "The model shows how our neurons are precisely evolved to use every bit of capacity." Have your say in our news democracy.
