Okay, I have a problem.
When exploring the unknown and covering distances of thousands of
light years you start to speak in superlatives of the things you see.
I mean, Black Holes, Supergiants, Nebula after Nebula? Planets with
indigenous life? Not long ago, this was the stuff of legends and no
wonder you start to choose the highest categories of words that come
into your mind.
And here I am, having
reached the Eta Carina Nebula; and there are no more superlatives
left.
I have described other things as 'amazingly beautiful', 'awe
inspiring' and 'truly magnificient'. What else is there now for this
jewel in space? It is like an arrangement of red, orange and dark
curtains falling down, thus revealing its intriguing interior, which
seems to be a small cosmos of its own.Eta Carina Nebula is
the heart of the Carina Molecular Complex. Well, in fact it is the
'last' of multiple structures in the Complex, whereas other clusters
and nebulae lie 'in front' of it when approaching from Sol (or Alioth
in my case). But it is also the climax, the beautiful crescendo of a
galactic cloud some thousand light years wide.
The nebula itself was once thought to
be (at least in part) the product of ejected planetary material from
a Wolf-Rayet star. There is no WR in the nebula, however, so maybe it
already died many years ago. The death of stars is a common sight in
and around as there are some Neutron Stars and also a couple of Black
Holes in the vicinity. These violent deaths in the past may (or rather must)
have contributed to the nebula's immense gas columns. These columns, like I said, seem like curtains to me and astronomers of old attributed several flashy names to them, like the Keyhole Nebula (which is indeed a substructure of Eta Carina Nebula so to say), the Homunculus Nebula and even a 'Finger of God'. Speaking of fingers, when you look at it from a distance the nebula looks like a hand, don't you think? A hand that was somehow blown into its shape by cosmic winds from 'bottom to top'.
All right, hands and death aside, there is also star formation that can be observed in and around the Carina
structure, too. There are many T Tauri stars lying closely together
and the occasional massive O type star, including the supermassive
Eta Carinae system itself, already foreshadow the next wave of deaths
that will occurr here. This in turn will once again enrich the
interstellar medium for new stellar births. It all comes full circle
here.With all this to discover the Eta
Carina Nebula is a definite 'must' for any explorer going in this
direction. For me, it's 'Sayonara Carina!' as there are even more
superlatives out there on my way. I hope I will find the right words
for them.
Time to move on!
