APOD: The Great Nebula in Carina (2019 May 07)

Post by APOD Robot » Tue May 07, 2019 4:06 am

Image The Great Nebula in Carina

Explanation: What's happening in the center of the Carina Nebula? Stars are forming, dying, and leaving an impressive tapestry of dark dusty filaments. The entire Carina Nebula, cataloged as NGC 3372, spans over 300 light years and lies about 8,500 light-years away in the constellation of Carina. The nebula is composed predominantly of hydrogen gas, which emits the pervasive red glow seen in this highly detailed featured image. The blue glow in the center is created by a trace amount of glowing oxygen. Young and massive stars located in the nebula's center expel dust when they explode in supernovae. Eta Carinae, the most energetic star in the nebula's center, was one of the brightest stars in the sky in the 1830s, but then faded dramatically.

That is the most unpleasant astronomical pic I've seen! The choice of colour and the contours make it look like an ulcer.
Irrelevant, I know, to scientific value, but anyway.

The story behind the fading of the central star is very interesting.

Thanks, Orin! I like your positive comments. I don't have one right now, so I'm glad to see yours!

You used up all the smilies in your post, so you will have to imagine that I'm smiling and clapping here!

So...
Is today's APOD showing just part of the homonulculos(sp?) nebula?
Or is it embedded within the photo?

I like the guy in the corner looking down at the nebula.

It makes you wonder what he's thinking? :yes: "If I was an astrophotographer what knowledge would I gather from today's image" :?:
