Andromeda Galaxy in X-rays

What has the supermassive black hole at the center of the Milky Way’s galactic neighbor been up to? The Chandra X-ray Observatory provides all the details.

When mapping energetic atoms from the edge of our solar system, the Interstellar Boundary Explorer discovered an unexpected ribbon-like feature that researchers are still working to understand.

When a gas cloud collapses to form a star cluster, how many objects form, and what are their masses? Research published today provides answers about the low-mass end of the star and brown dwarf formation process.

Recent JWST observations have stirred up concerns about over-massive black holes in the early universe. A new study allays these concerns while showing that over-massive black holes are just scratching the surface of the full black hole population.
