A strange class of space rock known as a "dark comet" has qualities of both asteroids and comets — and the hard-to-spot objects may pose a larger threat to Earth than we thought, according to ...

Researchers are barely scratching the surface of these strange objects. A recent study suggested that nearly 60% of all near-Earth objects are dark comets that may have been a part of much larger ...

A new study has raised warnings about "dark comets" which are hard to detect and could pose a terrible threat to Earth.

‘Dark comets’ could reveal how Earth got its oceans Scientists still do not know where the water here on Earth came from. But two populations of so-called dark comets may tell us.

As researchers continue to study dark comets, they hope to unravel more mysteries about their nature and significance in the context of planetary formation and the development of life on Earth.

New research of dark comets explores how water that makes up the oceans acted as a key ingredient for the development of life on Earth — and brought us oceans.

Scientists have identified a new class of space rocks called "dark comets" that may be harder to detect and pose a greater danger than previously thought.

NASA's discovery of seven new "dark comets" doubles the known population of these asteroid-like objects with cometary behavior. These dark, elusive bodies, some near Earth and others further out ...

A dark comet is one that doesn't have a visible coma or tail, but when measured, has this additional non-gravitational acceleration. Taylor and their colleagues studied the seven known dark comets to ...
