Ring Around the Sun
A newly detected disk around the sun could narrow down our search for other star systems that might have planets orbiting around them.
Astronomers with the European Space Agency say they?ve found the first direct evidence of the bright dust ring, which is located beyond the orbit of Saturn. Young stars are known to have thick bands of dust, gas and debris. This dust gradually disappears into deep space, so if an older star such as the sun still has a dusty ring, some hidden source must be replenishing it. Replenishing the ring around the sun takes 50 tons of dust each second.
