A research team has discovered hundreds of radio filaments in the heart of the Milky Way. The long and vertical threads have been known for decades, the short ones have only just been discovered.

While several hundred vertical "threads" have been discovered, there are only a few hundred horizontal filaments that appear to be located on only one side of the black hole and point in its direction. The study was published in the Astrophysical Journal Letters and is based on data from the MeerKAT telescope in South Africa.
