The path to dark matter and other fundamental enigmas may be through a warped extra dimension, according to a new study that proposes a new theory of the universe.
The oddly coherent motion of small satellite galaxies is challenging our accepted model of the universe.
Dr. Aparna Venkatesan studies the distant reaches of space and time, while advocating for a night sky undamaged by orbital clutter.
Dr. Chanda Prescod-Weinstein has peered into the deep past of the cosmos, while also working toward a just and equal future in the scientific community.
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.
