Astronomy news update from NASA :
Most galaxies don't have any rings -- why does this galaxy have two? To begin, the bright band near NGC 1512's center is a nuclear ring, a ring that surrounds the galaxy center and glows brightly with recently formed stars. Most stars and accompanying gas and dust, however, orbit the galactic center in a ring much further out -- here seen near the image edge. This ring is called, counter-intuitively, the inner ring. If you look closely, you will see this the inner ring connects ends of a diffuse central bar that runs horizontally across the galaxy. These ring structures are thought to be caused by NGC 1512's own asymmetries in a drawn-out process called secular evolution. The gravity of these galaxy asymmetries, including the bar of stars, cause gas and dust to fall from the inner ring to the nuclear ring, enhancing this ring's rate of star formation. Some spiral galaxies also have a third ring -- an outer ring that circles the galaxy even further out.

Hey pal, You must know what's the featured article on Wikipedia, anon : The Wikipedia article of the day for August 7, 2017 is Disneyland Railroad.
The Disneyland Railroad is a 3-foot (914 mm) narrow-gauge heritage railroad and attraction in the Disneyland theme park of the Disneyland Resort in Anaheim, California, in the United States. Its route is 1.2 miles (1.9 km) long, has four train stations, and encircles almost everything in the park. The rail line, which was built by WED Enterprises, is operated with two steam locomotives built by WED and three historic steam locomotives originally built by Baldwin Locomotive Works. The attraction originated as a concept created by Walt Disney, who drew inspiration from the ridable miniature Carolwood Pacific Railroad built in his backyard. Since 1955 when the Disneyland Railroad first opened to the public at the park's grand opening, it has been consistently billed as one of the top attractions, and for many years visitors had to buy a top-tier ticket to ride the train. It is one of the world's most popular steam-powered railroads, with an estimated 6.6 million passengers served each year.
