¿ Astronomy Picture of the Day [1]Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2020 March 31 [2]See Explanation.

Wang et al.; Radio: [7]NRF, [8]SARAO, [9]MeerKAT Explanation: In how many ways does the center of our Galaxy glow? This enigmatic region, about 26,000 [10]light years away toward the constellation of the Archer ([11]Sagittarius), glows in [12]every type of light that we can see. In the [13]featured image, high-energy [14]X-ray emission captured by NASA's orbiting [15]Chandra X-Ray Observatory appears in green and blue, while low-energy [16]radio emission captured by [17]SARAO's ground-based [18]MeerKAT telescope array is colored red. Just on the right of the colorful [19]central region lies Sagittarius A (Sag A), a strong radio source that coincides with [20]Sag A*, our [21]Galaxy's central supermassive black hole. Hot gas surrounds Sag A, as well as a series of parallel radio filaments known as [22]the Arc, seen just left of the image center. Numerous unusual single radio filaments are visible around the image. [23]Many stars orbit in and around Sag A, as well as numerous small black holes and dense stellar cores known as [24]neutron stars and [25]white dwarfs. The [26]Milky Way's central supermassive black hole is currently being imaged by the [27]Event Horizon Telescope.
