The universe just keeps expanding—but gravity doesn’t slow it down. Now we might know why. A theoretical physicist in England has won a prestigious award for her work on the theory of massive gravity,
NASA’s Kepler Space Telescope has observed the flashy process by which a white dwarf is devouring its companion star. Brown dwarfs are sub-stellar objects that failed to sustain hydrogen fusion, warranting
Baby stars, just like baby humans, may experience rapid growth spurts in their infancies, according to one theory of star formation. But it has been challenging for scientists to directly observe this
If there's one thing we've experimentally determined to be a constant in the Universe, it's the speed of light in a vacuum, c. No matter where, when, or in which direction light travels, it moves at 299,792,458
Cosmologists don’t enter their profession to tackle the easy questions, but there is one paradox that has reached staggering proportions. Since the big bang, the universe has been expanding, but the known
One of NASA's most powerful space telescopes is retiring at the end of this month, after an illustrious 16-year career. The Spitzer Space Telescope launched nearly 16 years ago with a profound mission:
NASA astronauts Luca Parmitano and Andrew Morgan completed a six-hour spacewalk and fixed leaks in the cooling system of the Alpha Magnetic Spectrometer (AMS), a system that collects data on 'dark matter'
