NASA reported that the Hubble telescope made a spectacular spiral galaxy photography NGC 2903, part of the constellation Leo, 30 million light-years away from Earth.
About 75 percent of the galaxies in space are spiral. Milky Way has been reclassified into a spiral galaxy with a central part and spiral star-filled stars, as well as cosmic dust and gases.
The focus of NASA is currently focused on black holes, and spiral galaxies contain black holes that are once near the center. Hubble's research on spiral galaxies aims to uncover the connection between black holes and local galaxies.
