Researchers have found a suspected clump of dark matter lurking within the luminous halo of a well-known "Einstein ring." The mysterious object, the smallest of its kind ever seen, could help shed light on the universe's missing matter.

Researchers have discovered there was an anomaly in Earth's gravitational field between 2006 and 2008, potentially caused by a mineral shift deep within Earth's mantle. GRACE satellites detected a strange gravity signal at the time.

A near-Earth asteroid lurked undetected for decades until a telescope in Hawaii spotted it earlier this year. It may be Earth's newest quasi-moon.

Chinese astronomers have spotted a hidden supermassive black hole in the background of a peculiar gravitational wave event from a black hole merger, hinting that all three singularities were locked in a never-before-seen triple system.

Violent black hole collisions may create black hole 'morsels' no larger than an asteroid — and these bizarre objects could pave the way to unlocking new physics, a study claims.

Astronomers have announced the discovery of a new dwarf planet in our solar system, named 2017 OF201. Located far beyond Neptune, it orbits the sun every 25,000 years.

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

Astronomers discovered a planet that orbits its star so closely that its surface is being scorched into magma and vaporizing into space.

"The singularity is the most mysterious and problematic part of a black hole. It's where our concepts of space and time literally no longer make sense."
