Hubble Spies a Diminutive Galaxy
This NASA/ESA Hubble Space Telescope image reveals the subtle glow of the galaxy named IC 3430, located 45 million light-years from Earth in the constellation Virgo. This dwarf elliptical galaxy is part of the Virgo cluster, a rich collection of galaxies both large and small, many of which are very similar in type to this diminutive galaxy.
Like its larger elliptical cousins, IC 3430 has a smooth, oval shape lacking any recognizable features like arms or bars, and is missing much of the gas needed to form many new stars. Interestingly, IC 3430 does feature a core of hot, massive blue stars —an uncommon sight in elliptical galaxies — that indicates recent star-forming activity. Astronomers think that pressure from the galaxy ploughing through gas within the Virgo cluster ignited what gas IC 3430 had in its core to form the newer stars.
