Dark matter lenses, which distort and amplify light from background objects, may be more abundant in galaxy clusters than expected.
The last supernovas before the universe dies in a heat death will be twice-dead ancient relics on a mind-boggling time scale, according to astrophysicist Matt Caplan.
“Just months before the end, after we’ve lost the outer planets to the great and growing blackness, the Earth drifts away from the Sun, and the Moon from the Earth. We too enter the darkness, alone.”
Using another galaxy as a telescope created a trippy quadrupling effect in a rare image of an exploding black hole from the early universe.
For years, scientists debated whether the glow was a telltale sign of dark matter. A new study refutes that theory, but that only deepens the mystery.
What if the Earth, the galaxy, and all the galaxies near us were enclosed in a weirdly empty bubble? This scenario could resolve some longstanding questions about the nature of the universe.
The blazar—powered by an extremely bright black hole that can blast a hole through galaxies—is the most ancient ever discovered, sending radio signals from the early universe
'Dark Emulator' churns out virtual universes in seconds, so scientists can probe mysterious large-scale dark matter structures that may be key to galaxy formation.
In a new experiment, scientists probed a theory that suggests a weird interaction between two of the biggest mysteries in physics could be why our universe exists in the first place.
Scientists are finding that galaxies can move with each other across huge distances, and against the predictions of basic cosmological models. The reason why could change everything we think we know about the universe.
Scientists think the universe is flat, but new observations suggest that we might actually be living in a gigantic sphere. Whoa.
The faint, 12-billion-year-old signal would lead scientists to the very first stars and illuminate the origins of the modern universe, dark matter, and, well, everything.
