Washington, Sept 30 (ANI): Astronomers of the University Jena have detected a stardust belt in extra-solar planetary systems hundreds of light years away from the Earth.
The debris discs are remnants of the formation of the planets.
This dust is of greatest importance for the astronomers, because it helps to draw conclusions about planet formation.
There are two debris discs in our solar system, the asteroid belt and the Kuiper belt amongst whose bodies the dwarf planet Pluto belongs.
What makes the Jena discovery so special is the tremendous distance from our solar system to the stars with the debris discs.
"These stars are hundreds of light years away from the Earth," said researcher Alexander Krivov.
The astronomers found evidence for the stardust belt around the stars TrES-2 in the Draco constellation and XO-5 in the Lynx constellation with the help of photometric analysis.
"The dust is warmed up by the star and radiates heat. We see that radiation curve is above the radiation curve of the star as a clear sign of the existence of stardust," Krivov added. (ANI)
