I assume you meant Hind's nebula, or Hind's reflection nebula, which is right. Also, it is called T Tauri South (or T Tau S). Your turn.

I can feel the Astronomy hype...

I'll ask another question then:

1.What is the object covered by the blue box? It is around 2.2 parsecs from the sun.
2. Name 3 unique/interesting things about this object?
3. Give an estimate for its surface temperature.

That's all right, your turn

A. Which of your objects is a type of object that has been described as “similar to insect cocoons”?
B. Why is it described that way?

Sorry, but since arvind_r answered my last question, it should be his/her turn to ask. If he takes too long a time (a week roughly) then you may go ahead.

Sorry, I didn't know that was the etiquette. I was hoping to see some more questions! I need help making practice tests!

Besides, I'm a mom/coach, so I'm not supposed to answer. I thought I could ask though!

It seems this thread is rather empty, so I'll answer it (Click to Show Hidden Text)

1. Barnard 68, which is a bok globule (or dark absorption nebula)
2. Bok globules are star formation centers, which, like cocoons, collect energy and matter for the star to begin fusing hydrogen in the main sequence (I could have put that in more scientific terms, but I think I got the idea across :) )

[sciolymom]

Correct, Magik! Also, they are like insect cocoons because they protect the interior from outside radiation and stellar winds.
