An artist's depiction of the halo of hot hydrogen gas surrounding the Milky Way galaxy (center) and two satellite galaxies, the Large and Small Magellanic Clouds. The halo is more extended that astronomers originally thought, and contains enough hydrogen gas to resolve the problem of the universe's missing baryonic mass.

Hubble’s Mesmerizing Portrait of Star Cluster NGC 346

$What looks like a single large, bright star (but is two) shines with bright purple diffraction spikes at the center of a large, diffuse cylinder of gas and dust that is tipped to the right. At the center is a bright pink clumpy cloud that takes up about 25% of the view. There are two large rings seen at a roughly 60-degree angle that appear joined at top left and bottom right. The edges are denser, and form shallow V-shapes that go inward. The rings appear orange at top left and bottom right, and are blue at bottom and center right. There is diffuse orange material around the body. The black background of space is speckled with tiny stars and galaxies mostly in blues and yellows. Areas Webb did not observe are along the top edges, a thin vertical near the nebula at top left, and at the bottom left and right corners.
