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 ...

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

The first dark comet was spotted in 2016 when scientists noticed that the trajectory of near-Earth asteroid 2003 RM was a little wonky for your typical space rock.

‘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.

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.

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.

Astronomers posed over the past decade that dark comets, or objects that resemble asteroids but move like comets, may exist. Now, scientists have found a total of 14 of them.

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 ...

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 ...
