The latest Hubblecast is now out! In this episode we present a new stunning Hubble image. M74 is a beautiful spiral galaxy located 32 million light years away. Hubble imaged the galaxy with its Advanced Camera for Surveys between 2003 and 2005.
“Messier 74, also called NGC 628, is a stunning example of a ‘grand-design’ spiral galaxy that is viewed by Earth observers nearly face-on. Its perfectly symmetrical spiral arms emanate from the central nucleus and are dotted with clusters of young blue stars. In the new Hubble image we can also see a smattering of bright pink regions decorating the spiral arms.
These are huge, relatively short-lived, clouds of hydrogen gas which glow due to the strong radiation from hot, young stars embedded within them; glowing pink regions of ionized hydrogen (hydrogen that has lost its electrons).”
