Check out this awesome starry driveway! The beautiful stellar effect was achieved by mixing glow stones with gravel. You might have already encountered glow stones, which are often used in aquariums. They’re a synthetic aggregate of photoluminescent pigment and synthetic resin.
According to Jinan Chenghao Technology, “When exposed to light sources, the photoluminescent pigment within Glowstone becomes chemically excited and will afterglow (i.e. glow in the dark).” The glow is initially very strong, but then slowly dulls over night.
We’d love to see all of the driveways and sidewalks in our neighbourhood covertly decorated like this. We could go out each night for a star walk. And during the day passersby would be none the wiser.

FORD OF THE RINGS The Saturnian moon Daphnis and Pan stir ripples in the giant planet’s rings due to their gravitational effect. Five-mile-wide Daphnis (lower left) is perturbing particles in Saturn’s A ring, while 17-mile-wide Pan (upper right) has kicked up dark wakes in the ring propagating toward the middle of the image. This picture was taken in visible light by the Cassini spacecraft’s narrow-angle camera on June 3, 2010, at a distance of about 329,000 miles from Saturn. (Photo: NASA / JPL-Caltech / SSI via MSNBC)
STAR BLAZER A meteor is seen streaking through the skies above Reno, Nevada last weekend. A NASA official estimate that the min-van-sized meteorid weighed about 70 metric tons and at the time of disintegration released energy equivalent to a 5-kiloton explosion.
