Under pressure...⁣

⁣The @NASAHubble Space Telescope imaged this dwarf galaxy, which lives 52 million light-years from Earth in the constellation Virgo. The Virgo galaxy cluster is also home to some relatively dense gas, causing many galaxies like this one to live under the pressure it exerts, known as ram pressure.⁣

⁣
Ram pressure from intergalactic gas can dramatically impact star formation in galaxies like this one. On one hand, the force can drive out gases and dust that lead to star formation, slowing or stopping star production entirely. Conversely, the pressure can compress these star-forming ingredients, boosting the formation of new stars.⁣

Image Description: In this image, black space is dotted with orange and yellow stars and galaxies, widely ranging in shape and size. Prominent in the left portion of the image is a dusty spray of stars making up the dwarf galaxy. It glitters with small white and light-yellow stars.⁣
