There are many nebulae in our galaxy: The Orion nebula, the Eagle nebula, the Trifid nebula, etc. All of these have star forming regions where new solar systems are being formed.
We do see nebula in other galaxies. The Tarantula nebula is in a Magellanic cloud (I forget which one; Large or Small...I think Large) which is another galaxy. Nebula with star forming regions tend to be fairly bright because there are often a lot of O and B type stars lighting them up. So we do see and catalog such regions in the galaxies fairly close to us (within a few 10's of millions of light years).
Next, the star forming nebula are in the process of *contracting* to form stars, not exploding. Often the contraction is caused by supernovae close by, though.
Finally, the Big Bang was *not* an explosion in this sense! The explosion of a star is not even close to what happened in the Big Bang. One huge difference is that the Big Bang was an expansion of space itself, not an explosion of matter through space. The phrase 'Big Bang' is unfortunate (and created by an opponent of the theory) since it suggests such a convention explosion. Tha name alone probably leads to more confusion about it than anything else.

Your question doesn't make sense. First of all a nebula doesn't explode, it's an explosion that transformed it into a nebula. Also, it doesn't explode in the big bang, it explodes because a star dies. I don't know of any famous nebula in our galaxy. However, many nebula are considered to be factories for solar systems. For example, we have the Eagle nebula and the Orion nebula. These 2 are considered to be extremely active in creating big blobs of ionized Hydrogen (H2) which is the base for a star to form. They could also form proto-planetary disks, but the scale of these nebulae is too big to form a simple proto-planetary disk.

Nebulae can't explode. As for part two of your question...there are many star-forming nebula regions in our galaxy...nost notably the Orion Nebula complex. FYI, age of a particular nebula has little do with it being a star-forming region.

That's sort of two different questions. Most of the news, most of the time, center on stellar nurseries in the direction of Orion's belt. One link below is a recent report for observations in a different place. The another link briefly describes the current timescale for the very first stars and the resulting second generation as a point of reference to how quick (in astronomical time) these things could happen.

nebulas are complex gases and plasma. If they condense into a dense area stars can form within them however you must be confused about the big bang concept.

google gamma ray bursts
they are the closest thing to a big bang that we know of, though compared to the big bang they are mere mini- bangs.
