During the January meeting of the American Astronomical Society, NASA released a detailed image of the galactic centre region:

Even more amazing is a detail not included in the NASA release but on astronomer Daniel Wang's own website:

This is the most detailed image I've ever seen of the galactic nucleus. This brings out great detail in the central spiral swirling around the ball of hot gas surrounding Sgr A*, the 4 million solar mass black hole at the core of the Milky Way.
