Mergers are a part of a galaxy's life in this Universe. Though clear signs of these mergers fade over hundreds of millions of years, evidence is still present, yet obscured, in the galaxies that experience them. The powerful JWST has made it possible to find this evidence, and it did so recently for Centaurus A.

The Artemis II crew participates in the dedication of the Apollo 14 Moon tree at the Lunar Receiving Park at NASA's Johnson Space Center. This tree is a second-generation Apollo Moon tree of the loblolly pine species.

This tree is a second-generation Apollo Moon tree of the loblolly pine species. The original Apollo Moon trees were grown from seeds carried aboard Apollo 14 by NASA astronaut Stuart Roosa, a former U.S. Forest Service smoke jumper. Upon return to Earth, the seeds were germinated by the Forest Service, and the resulting seedlings were planted throughout the United States and around the world.
