Water persisted in Mars' Gale crater for longer than previously thought
Water persisted in Mars’ Gale crater for longer than previously thought
Imperial College London and NASA researchers have found signs that water was plentiful in Mars' Gale crater for longer than previously thought. Billions of years ago, Mars was home to abundant water, and its Gale crater contained a lake. Gradually, the climate changed, drying the Red Planet and creating the dusty desert world we know today.

Astrophysicists unveil new phenomenon challenging textbook definition of white dwarf stars
Scientists have revealed why some white dwarfs mysteriously stop cooling - changing ideas on just how old stars really are, and what happens to them when they die. White dwarf stars are universally believed to be 'dead stars' that continuously cool down over time. However, in 2019, data from the European Space Agency's (ESA's) Gaia satellite discovered a population of white dwarf stars that have stopped cooling for more than eight billion years.

Scientists closer to solving mysteries of universe after measuring gravity in quantum world
Scientists are a step closer to unravelling the mysterious forces of the universe after working out how to measure gravity on a microscopic level. Experts have never fully understood how the force which was discovered by Isaac Newton works in the tiny quantum world. Even Einstein was baffled by quantum gravity and, in his theory of general relativity, said there is no realistic experiment which could show a quantum version of gravity.
