The agency responsible with filling the government's coffers with cutting-edge tech is funding a controversial drive that's based on unproven science.
A new study by a pair of astronomers from the Harvard Smithsonian Center for Astrophysics (CfA) has suggested that 'Oumuamua may actually be a light sail of extra-terrestrial origin.
How the Kepler Space Telescope discovered there are more planets than stars in the galaxy.
Based on observations by the European Southern Observatory's GRAVITY instrument, this simulation shows gases swirling around the black hole at the center of the Milky Way — at just 30% the speed of light. It's "the first time material has been observed orbiting close to the point of no return."
Lurking in the depths of the mathematics of Einstein’s general relativity is an object even stranger than the mysterious black hole. In fact it’s the black
One of the rockets four boosters failed to properly fall away, sending the rocket into a spin and forcing the astronauts on board to abort.
Something very large and dark occupies the center of our galaxy, and new data suggest that it is indeed a black hole.
Hot spots have been discovered orbiting just outside the supermassive black hole at the galaxy's center. Their motions have given us the closest look at that violent environment.
NASA engineers know a thing or two about building things under pressure, and it's fair to say that that talent extends to decorating pumpkins for Halloween.
