NASA Unveils December 2025's Cosmic Wonders: Comets, Galaxies, Black Holes & More

• Interstellar Comet 3I/ATLAS, showing familiar chemistry and tails, passed the Sun in October and will approach Earth in mid-December before departing the Solar System.
• The M77 spiral galaxy features an active core powered by a supermassive black hole, with Hubble images revealing its dust-lined arms and young blue star clusters.
• A visualization depicts the sky from a camera falling into a 4-million-solar-mass black hole, illustrating gravity's warping effects, including a looped Milky Way and a stretched image below the horizon.
• Massive elliptical galaxy NGC 1316 (Fornax A) interacts with NGC 1317, creating looping star streams from cosmic collisions within the Fornax cluster.
• Binary star KX Andromedae generates stunning 19-light-year bipolar jets, formed by material transferring from a cool giant to a hot B-type companion star.
