A new image from the James Webb Space Telescope captures dwarf galaxies NGC 4490 on the left and NGC 4485 glowing at the upper right, connected by a glowing bridge of gas and dust dotted with bright blue star-forming regions. Because dwarf galaxies closely resemble the low-mass, gas-rich, metal-poor systems that populated the early universe , their collisions and gas exchanges provide a valuable window into how the first galaxies formed and evolved, according to a statement from the European Space Agency. The new image from the Webb telescope shows dwarf galaxies NGC 4490 on the left and NGC 4485 glowing at the upper right.
