Astronomers may have uncovered a unique process for how the universe's largest elliptical galaxies continue making stars long after their peak years of star birth.
Scientists have made a huge step forward for physics. Scientists have produced the best ever constraint of the gravitational constant measured outside of our solar system.
Milky Way-like galaxies may have existed in the early universe. A new computer simulation reveals that large disk galaxies, much like our own Milky Way, may have existed in the early days of the universe.
Astronomers have discovered a giant, swirling disk of gas that represents a galaxy being born. The forming galaxy is actively being fed cool primordial gas that traces back to the Big Bang.
NASA is tracking a mysterious group of asteroid outcasts with NEOWISE. They've spotted a family of space rocks near the asteroid-rich abyss between Mars and Jupiter in order to learn a bit more about them.
Resources aren't easy to find on the moon or Mars, and that's why NASA is building drones to find them.
NASA's satellite has captured spectacular new images of the dark side of the moon.
NASA's Mars Curiosity rover has officially spent three years moving across the Red Planet. Now, researchers are celebrating this fact by looking back on all of the amazing discoveries the robot has made during that time.
The mystery behind Saturn's rings has finally been solved. Scientists have found that planetary rings, such as the ones orbiting Saturn, have a universally similar particle distribution.
Astronomers have spotted the ghostly remnants of galaxy interactions in a nearby galaxy group.
A NASA robot may be set to build rocket parts for a Mars mission.
