NASA's Perseverance rover captured a striking new image of massive, wind-carved sand formations known as "megaripples" during its latest exploration stop on the Red Planet.
A new study by Manuel Barrientos and colleagues from the University of Oklahoma reveals that between 0.6% and 2.5% of white dwarfs in our solar neighbourhood undergo dramatic cooling delays that could extend habitable zones for billions of additional years. The secret lies in an element known as neon-22, which after carbon and oxygen, is the most abundant element inside white dwarfs.
