An illustration of galaxies distorting the structure of space-time in the expanding universe. New theoretical work suggests that the cosmic expansion is not constant — it can dramatically change direction and intensity. (Image credit: NASA/JPL-Caltech) Dark energy could have changed…
Saturn has at least 274 moons, more than any other planet in our solar system. (Image credit: dottedhippo via Getty Images) If you look up at the starry sky on a clear night, the brightest and most visible object is…
An artist’s illustration of Saturn and its rings. (Image credit: NASA/JPL-Caltech) Astronomers have discovered 128 new moons that have never been seen before orbiting Saturn. That’s nearly twice the number of moons of all the other planets in the solar…
