The Night Sky.
At first glance, the center of the Milky Way seems like a very inhospitable place to try to form a planet. Stars crowd each other as they whiz through space like cars on a rush-hour freeway. Supernova explosions blast out shock waves and bathe the region in intense radiation. Powerful gravitational forces from a supermassive black hole twist and warp the fabric of space itself.
Or, perhaps, would be more appropriate to call them "sisters" – because it’s stars. Astronomers think that when the sun arose with it, the same cosmic event, they made a lot of other stars.
