Explanation: This cosmic expanse of dust, gas, and stars covers some 6 degrees on the sky in the heroic constellation Perseus. At upper left in the gorgeous skyscape is the intriguing young star cluster IC 348 and neighboring Flying Ghost Nebula with clouds of obscuring interstellar dust cataloged as Barnard 3 and 4. At right, another active star forming region NGC 1333 is connected by dark and dusty tendrils on the outskirts of the giant Perseus Molecular Cloud, about 850 light-years away. Other dusty nebulae are scattered around the field of view, along with the faint reddish glow of hydrogen gas. In fact, the cosmic dust tends to hide the newly formed stars and young stellar objects or protostars from prying optical telescopes. Collapsing due to self-gravity, the protostars form from the dense cores embedded in the molecular cloud. At the molecular cloud's estimated distance, this field of view would span over 90 light-years.

Perseus was a hero in Greek mythology. So now the constellation is heroic just because it’s named for him?

How much is 1 degree in the sky?
The tip of your little finger held at arm’s length
covers about 1 degree.
A full moon is about 1/2 degree across.
(found it on the internet, it must be true)
A beautiful song. I also love Willy Nelsonās version, but his voice canāt compare to Nat King Coleās.
beautiful

Willy Nelsonās voice is like two files being rubbed together compared to Nat King Cole’s.....................
Lol, yeah, but he did have a great arrangement of it.
No Sinatra, for sureā¦š
