Mars is often called the Red Planet, but a recent image captured by NASA’s Perseverance rover from the surface would go some way to contradicting that. Earlier this year, Perseverance snapped a sunset from Mars in which the Sun looks blue, a sight which would never be seen from our own planet. The photograph was taken on the rover’s 842nd day on the planet, and shows a Martian horizon with the sun setting behind causing an eerily cool glow. Because of Mars’ distance from the Sun, it gets less sunlight than we do on Earth. Even at its sunniest, it gets less than half our quota of light from the star. And the planet’s atmosphere, which is weaker than Earth’s, is mainly made up of carbon dioxide, with a small amount of nitrogen and a trace of oxygen. This gaseous mix and weak atmosphere causes the light to scatter in a blue haze across the sky. It’s the same process which gives us our blue sky during the daytime, when the light has less atmosphere to penetrate before it reaches our eyes. On Earth, this changes when the sun dips below the horizon, and the light has more atmosphere to penetrate, filtering our blue and violet wavelengths, leaving only reds and oranges. Meanwhile on Mars, the sunlight interacts with the dust hanging in the atmosphere, scattering red light during the day. At twilight, that red light is filtered away, leaving blues. Atmospheric scientist Mark Lemmon of Texas A&M University told Science Alert: "The colours come from the fact that the very fine dust is the right size so that blue light penetrates the atmosphere slightly more efficiently. “When the blue light scatters off the dust, it stays closer to the direction of the Sun than light of other colours does. “The rest of the sky is yellow to orange, as yellow and red light scatter all over the sky instead of being absorbed or staying close to the Sun.” Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.

The manhunt for convicted killer Danelo Cavalcante has now widened and local schools have been shuttered after he was spotted on trail camera footage breaking past a police perimeter on Monday night. Cavalcante, 34, escaped from Chester County Prison, Pennsylvania, on Thursday days after he was sentenced to life without parole for stabbing his ex-girlfriend Deborah Brandão, 31, to death in front of her two small children. He is also wanted for a 2017 murder in Brazil. During the six-day search for the escaped prisoner, multiple sightings have been reported with law enforcement setting up a two-mile perimeter around a wooded area where he was believed to be holed up. On Monday, officials then broadcast a message from the killer’s mother urging her son to surrender. But, in a morning update on Tuesday, police revealed that Cavalcante had been caught on camera managing to sneak past the perimeter the night before. As a result, police have now expanded the police perimeter and shuttered the Kennett Consolidated School District in Chester Count “out of abundance of caution”. Members of the public have been urged to secure their homes, outbuildings and vehicles from the dangerous killer. Read More Danelo Cavalcante killed his girlfriend in front of her children.

The White House on Wednesday strongly denied that the US government posed any threat to an ex-Senate staffer who has claimed President Joe Biden sexually assaulted her in a Senate office building hallway in the 1990s. The former staffer, Tara Reade, announced on Tuesday that she has moved to Russia, where she said during an interview with the state-owned Sputnik News website that she feels “surrounded by protection and safety” there. Asked about her claims in light of her announcement that she has moved to Russia and is seeking citizenship there, National Security Council spokesperson John Kirby replied: “We'd be loath to comment on the on the musings of a potential Russian citizen.” Pressed further on whether the White House believes her allegations against Mr Biden could have been movtivated by an affinity for Russia, Mr Kirby said he “could not get inside her head and speak for her motivations and intentions”. But he did specifically address Ms Reade’s claim that she has moved to Russia because the US government was a risk to her life, calling those allegations “absolutely false” and “baseless”. “There’s nothing to that,” he added. Ms Reade, who worked for Mr Biden during a brief period in 1993, accused the then-former vice president of touching her inappropriately in 2019, when Mr Biden was contemplating entry into the 2020 presidential election. In mid-2020, when he was poised to secure the Democratic Party’s nomination for president, she claimed he’d sexually assaulted her in a heavily-trafficked hallway in the Russell Senate Office Building. Mr Biden has strenuously denied the allegations. The former Senate staffer’s credibility took a hit after news outlets began scrutinizing her background after she made the assault allegations against Mr Biden. A university she attended, Antioch University, disputed her claim to have earned a Bachelor’s degree while studying there, and former associates came forward to recount instances in which they’d felt she’d been dishonest or deceitful in her dealings with them. A well known attorney, Douglas Wigdor, terminated an attorney-client relationship with her in May 2020 after it was revealed that she had not earned a degree from Antioch as she’d claimed publicly.
