A distorted dwarf galaxy, obscured by dust and by bright outbursts caused by star formation, floats roughly in the center. Tendrils of gas stretch up from the plane of the galaxy. A few distant galaxies are visible in the background around it, many as little spirals, and also including a prominent elliptical galaxy. A bright star hangs above the galaxy in the foreground, marked by cross-shaped diffraction spikes. The galaxy appears in shades of white and blue, while the distant galaxies are spots of orange.

Hubble Views a Galaxy Under Pressure

This NASA/ESA Hubble Space Telescope image shows LEDA 42160, a galaxy about 52 million light-years from Earth in the constellation Virgo. The dwarf galaxy is one of many forcing its way through the comparatively dense gas in the massive Virgo cluster of galaxies. The pressure exerted by this intergalactic gas, known as ram pressure, has dramatic effects on star formation in LEDA 42160.
