Demolition Derby of Comets Surrounding a Young Star
A new study has found a young star which is home to at least one alien planet and is also ringed by a vast cloud of comets. It is just like our own solar system, but there is one big difference that makes it unique. There are nearly 83 trillion comets that surround the star. The massive amount of commets results in collision among many every day, due to which thousands are destroyed. Due to these collision, there is so much dust that is produced around the star, which would be equivalent to 2,000 comets, each a half-mile wide being obliterated each day. The discovery has been made by European Space Agency, which is terming these collisions as a demolition derby in the form of comet massacre.
Although it is not clear whether the dust surrounding the star is in fact from the collision of the comets, there are speculations that even a few less crashes of bigger comets of 6 miles across could have done the same. Lead author of the study, Bram Acke of the University of Leuven, in Belgium, was really surprised after the revelations, stating that the number that is coming out of this research is extremely large. These comets that encircle the star are nearly 25 light years away from Earth. The team of researchers observed this phenomenon with the far-infrared Herschel space observatory, which spotted the telltale dust created by the constant collisions of comets in motion.
Looking at the size of the comets, and the cloud they have created, it could be estimated that their number could be between 260 billion and 83 trillion. Revelations like these are pretty common but the sheer size of the comets surrounding this star is extra ordinary.
