These Two Galaxies Are Tying The Knot And Producing Stars

The dwarf galaxies NGC 4490 and NGC 4485 are caught interacting with one another in this ESA/JWST Picture of the Month. The pair are about 24 million light-years away, but that didn't stop the powerful James Webb Space Telescope from resolving their stellar populations or the gas bridge spanning between the two galaxies.

The European Space Agency has release its ESA/Webb Picture of the Month and it features a pair of dwarf galaxies engaged in a tentative dance, like nervous partners at a social. The pair are a staggering 24 million light-years away. But even at that great distance, the pair of galaxies is the closest-known interacting pair of dwarfs, other than the Milky Way's Magellanic Clouds, where both the stellar populations and the gas bridge linking the galaxies have been observed.
