It's an interstellar treat! The Southern Delta Aquariid meteor shower is expected to peak on the night of Thursday, July 28 to the predawn hours of Friday, July 29. NASA said that there will be approximately 20 meteors visible each hour with a meteor velocity of 41 km (25 miles) per second. Their radiant appears from the constellation Aquarius, moving southeast. The third brightest star within this constellation is called Delta. The shower gets its name from this star and the constellation.

Meteors come from leftover comet particles and bits from broken asteroids. When comets orbit the Sun, the dust they emit gradually spreads into a dusty trail around their orbits. Every year the Earth passes through these debris trails, which allows the bits to collide with our atmosphere where they disintegrate to create fiery and colorful streaks in the sky. The Delta Aquariid isn't the only shower in the sky this month. The Perseid meteor shower, which NASA calls the "greatest meteor shower of the year," began on July 17 but will not peak until August 13.
