South Africa’s MeerKAT radio telescope array spotted more than 1,300 galaxies in this patch of sky. Prior to MeerKAT, there were 70 known galaxies in the region. The panels to the right show two distant galaxies with massive black holes at their centers. At lower left is a galaxy approximately 200 million light years away, where hydrogen gas is being used up to form stars in large numbers.

The six colors of the LGBT rainbow flag symbolize life (red), healing (orange), sunlight (yellow), nature (green), serenity (blue), and spirituality (purple). The white stars on the U.S. flag symbolize the 50 states, and their position on a blue background symbolizes, in the words of Ben Franklin and John Adams, “a new constellation.”
