Astronomers at Lund University have detected exocomets orbiting a young sun-like star in another solar system. These observations suggest that comets may serve as carriers of water from the cold outer regions of planetary systems to the inner zones where planets are forming. This discovery provides insight into the mechanisms that could deliver water to developing planetary systems.


This finding helps explain how water might have arrived on Earth and other planets during their formation. Understanding water transport mechanisms in young planetary systems has implications for assessing the potential habitability of exoplanets and the prevalence of water-bearing worlds throughout the universe.


Astronomers at Lund University in Sweden have found evidence of exocomets—comets in other solar systems—orbiting a young star similar to our sun. The observations point to a possible mechanism for how water might be transported from the cold outer regions of the planetary system to regions where planets form.
