OPPORTUNITY EXPLORES FOR 14 YEARS DISCOVERS EVIDENCE OF ANCIENT FLOWING WATER NARRATOR: Over 50 years of Mars exploration has revealed intriguing clues, suggesting Mars has a surprisingly watery past. ASHWIN VASAVADA: There’s a lot of evidence for ancient flowing water on Mars. For one thing, there’s a lot of rivers that once coursed across the surface that are now dry, today. There’s also evidence for floods that catastrophically scoured the surface. JOHN GROTZINGER: It’s undeniable that the early history of Mars was much wetter than it is today. STEVE SQUYRES: The surface of Mars is...

    “To me, Mars is the uncanny valley of Earth,” said planetary geophysicist Kevin Lewis of Johns Hopkins University. “It’s similar but was shaped by different processes. It feels so unnatural to our terrestrial experience.” In a 2019 paper in Science, NASA researchers detail how they repurposed sensors used to drive the Curiosity rover and turned them into gravimeters, which measure changes in gravitational pull. That enabled them to measure the subtle tug from rock layers on lower Mount Sharp, which rises 3 miles (5 kilometers) from the base of Gale Crater and which Curiosity h...

11 April 2021, 2:36 pm EDT By NASA on Apr. 8 released a breathtaking photo of a sea of dunes taken from Mars' North Pole. The photo's release, which was aptly titled "Blue Dunes on the Red Planet," is part of a special set of images marking the 20th anniversary of the Mars Odyssey orbiter. NASA's 'Blue Dunes on the Red Planet' According to Insider's Apr. 11 report, the photo NASA released shows the dune's wind-sculpted lines surrounding Mars' frosty northern polar cap. The colors were due to the fact that the photo is a false-color image, which means that the cooler temperatures are recor...

  One early result of the ongoing Dark Energy Survey is the previously untold story revealed by old, giant RR Lyrae pulsating stars, which tell scientists about the region of space beyond the edge of our Milky Way. In this area nearly devoid of stars–the motion of the RR Lyrae stars hints at the presence of an enormous halo of invisible dark matter, which may provide clues to how our galaxy evolved over the last 12 billion years. One of the Biggest Mysteries in Science Dark matter, one of the enduring mysteries in science, is “dark” in the sense that it doesn’t emit radiation or hard...
