Heart galaxies merging, 11-30-22 (credit: JWST)

A pair of galaxies have been observed combining into one galactic love-letter seen by the Webb space telescope. The heart-shaped galaxies, in the constellation Delphius, are nearly 500 million light-years distant from Earth so their valentine has taken a very long, long time to be delivered. According to NASA, the Webb telescope was peering into details of galactic evolution, particularly Luminous infrared galaxies, that are very bright with infrared heat signatures, with far more luminous, 100 billion times more, than that of our Sun. A pretty 'hot' love-letter, indeed! WHB
