. LEDA 16643 is a spiral galaxy — although it displays a somewhat irregular and ill-defined structure.

Also known as ESO 486-21 and IRAS F05013-2529, this galaxy is located in the constellation Lepus, 37.2 million light-years from Earth.

The color image of LEDA 16643 was made from separate exposures taken in the visible and UV regions of the spectrum with Hubble’s Wide Field Camera 3 (WFC3).

Seven filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.
Hubble observed LEDA 16643 while performing a survey — the Legacy ExtraGalactic UV Survey (LEGUS) — of 50 nearby star-forming galaxies.
The LEGUS sample was selected to cover a diverse range of galactic morphologies, star formation rates, galaxy masses, and more.

Astronomers use such data to understand how stars form and evolve within clusters, and how these processes affect both their home galaxy and the wider Universe.

LEDA 16643 is an ideal candidate for inclusion in such a survey as it is known to be in the process of forming new stars, which are created when large clouds of gas and dust within the galaxy crumple inwards upon themselves.
