Hubble Observes NGC 4248
NASA has released a stunning image snapped by the NASA/ESA HubbleSpace Telescope of the irregular/spiral galaxy NGC 4248.
It was discovered on February 9, 1788, by the British astronomer William Herschel.
Also known as LEDA 39461 and UGC 7335, NGC 4248 lies in the constellation Canes Venatici, approximately 23.5 million light-years away.
This image of NGC 4248 was produced by Hubble as it embarked upon compiling its first 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.
They also can learn about 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 color image of NGC 4248 was made from separate exposures taken in the visible, ultraviolet and infrared regions of the spectrum with Hubble’s Wide Field Camera 3 (WFC3).
Five filters were used to sample various wavelengths.
The color results from assigning different hues to each monochromatic image associated with an individual filter.
