This Hubble image of the week shows the clump of glowing gas, dust, and glittering stars known as spiral galaxy NGC 4248. NGC 4248 is located roughly 24 million light-years away in the constellation of Canes Venatici.
This image was produced by the NASA/ESA Hubble Space Telescope as it embarked upon compiling the first Hubble ultraviolet “atlas,” for which the telescope targeted 50 nearby star-forming galaxies. A sample spanning all kinds of different morphologies, masses, and structures. Studying this sample can help us to piece together the star-formation history of the Universe.
By exploring how massive stars form and evolve within such galaxies, astronomers can learn more about how, when, and where star formation occurs, how star clusters change over time, and how the process of forming new stars is related to the properties of both the host galaxy and the surrounding interstellar medium (the “stuff” that fills the space between individual stars).
This image is formed from observations from Hubble’s Wide Field Camera 3.
