A giant comet from the outskirts of our solar system has been discovered in six years of data from the Dark Energy Survey. Comet Bernardinelli-Bernstein is estimated to be about 1000 times more massive than a typical comet, ...
A cluster of comet fragments believed to have hit Earth nearly 13,000 years ago may have shaped the origins of human civilisation, research suggests.
Comets that circle the Sun in very elongated orbits spread their debris so thin along their orbit or eject it out of the solar system altogether so that their meteor showers are hard to detect. From a new meteor shower survey ...
A new study by a Belgian team using data from the European Southern Observatory's Very Large Telescope (ESO's VLT) has shown that iron and nickel exist in the atmospheres of comets throughout our Solar System, even those ...
If asked where meteorites come from, you might reply "from comets." But according to our new research, which tracked hundreds of fireballs on their journey through the Australian skies, you would be wrong.

In October 2017, humanity caught its first-ever glimpse of an interstellar object—a visitor from beyond our solar system—passing nearby the sun. We named it "Oumuamua, and its unusual properties fascinated and confounded ...
The world's first ground-based observations of the bare nucleus of a comet nearing the end of its active life revealed that the nucleus has a diameter of 800 meters and is covered with large grains of phyllosilicate; on Earth ...
In a landmark study, a team led by researchers at the Perelman School of Medicine has discovered—and filmed—the molecular details of how a cell, just before it divides in two, shuffles important internal components called ...
