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.

The universe went in “extreme slow motion” at its beginning, and has dramatically sped up since, scientists have found. The discovery, predicted by Einstein’s general theory of relativity, was finally confirmed after scientists observed the universe soon after the Big Bang. Einstein’s theory suggests that we should be able to see the distant universe, when it was much older than it is today, running much more slowly. But scientists have not been able to actually look that far and confirm the theory. Now scientists have used bright quasars as a sort of space clock, allowing them to measure time when the universe was much older than it is today. “Looking back to a time when the universe was just over a billion years old, we see time appearing to flow five times slower,” said Geraint Lewis from the University of Sydney, lead author on the new research. “If you were there, in this infant universe, one second would seem like one second – but from our position, more than 12 billion years into the future, that early time appears to drag.” Professor Lewis and other researchers gathered data from 200 quasars for the research. Quasars are very active supermassive black holes that sit in the middle of early galaxies, and hence provide a reliable way to look back at a much younger universe. Previous researchers have done the same using supernovae, or massive exploding stars. Those are useful but they are also difficult to see at the very very long distances of the early universe, meaning that the confirmation was limited only to about half the age of the cosmos. Now by using quasars scientists were able to look much further back, to just a tenth of the age of the universe, when it was only a billion years old. “Thanks to Einstein, we know that time and space are intertwined and, since the dawn of time in the singularity of the Big Bang, the universe has been expanding,” Professor Lewis said. “This expansion of space means that our observations of the early universe should appear to be much slower than time flows today. “In this paper, we have established that back to about a billion years after the Big Bang.” The work is described in a new paper, ‘Detection of the cosmological time dilation of high-redshift quasars’, published in Nature Astronomy.
