"A Look to the Heavens"
“Grand spiral galaxies often seem to get all the glory. Their young, blue star clusters and pink star forming regions along sweeping spiral arms are guaranteed to attract attention. But small irregular galaxies form stars too, like NGC 4449, about 12 million light-years distant. Less than 20,000 light-years across, the small island universe is similar in size, and often compared to our Milky Way's satellite galaxy, the Large Magellanic Cloud (LMC).

This remarkable Hubble Space Telescope close-up of the well-studied galaxy was reprocessed to highlight the telltale reddish glow of hydrogen gas. The glow traces NGC 4449's widespread star forming regions, some even larger than those in the LMC, with enormous interstellar arcs and bubbles blown by short-lived, massive stars. NGC 4449 is a member of a group of galaxies found in the constellation Canes Venatici. Interactions with the nearby galaxies are thought to have influenced star formation in NGC 4449.”

Been planning on acquiring a telescope for my own enjoyment. One not too expensive.
The description does not mention the twinkler in the photograph. Do you know if this is a fault in the Hubble?

If by Twinkler you mean the bright yellow star I think that one must be much closer and was just in the way of the desired view.
