Comets can exist outside the solar system

American astronomers say they have discovered six possible objects, comets around distant stars, a sign that comets are also popular out there rather than a special feature of the facial system. God.

Comets are also popular in other star systems

Researchers at the University of California at Berkeley and Clarion University in Pennsylvania (USA) say that giant disks of gas and dust surround every star outside the solar system.

This suggests that comets are also likely to be regular "residents" in those systems, according to the Guardian.

'This is a broken link in the study of current planet formation , ' said Barry Welsh, an astronomer at the University of California at Berkeley.

'We see dust disks, perhaps the basic material for forming planets, around countless stars, and we see planets, but we don't see more intermediate objects: onions "Crystal-like asteroids and comets ," Welsh said.

However, things changed when experts discovered six new comet systems were discovered between May 2010 and November 2012, thanks to the 2.1-meter telescope of the McDonald Observatory. Texas (USA).
