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 ...

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.

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 ...

Inner dark comets can be found within the inner solar system, which includes the planets Earth, Venus, Mars and Mercury, and move in nearly circular orbits around the sun.

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 ...

These so-called "dark comets," which have puzzled astronomers for years, could comprise up to 60% of near-Earth objects currently thought to be standard asteroids.

NASA has recently discovered some strange dark comets captured close to the Earth, and they are wondering where they are coming from. NASA found seven more “dark comets,” increasing the number of ...

One leading idea is that space rocks such as comets and asteroids delivered water to the Earth through impacts. As a planetary scientist, I’m curious about the kinds of space objects that could have ...

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.

Since ’Oumuamua was first spotted in 2017, my colleagues and I have identified other dark comets within the solar system. In our study, we found seven new dark comets, bringing the total to 14.
