shows that the Large Magellanic Cloud contains many nebula that are made of energetic hydrogen. It seems to be even more dramatic in black & white rather than in red.

The high resolution view is breath taking.

It makes me wonder what our galaxy would look like if photographed in this same manner. The LMC looks like it is wall to wall nebula.

I'd like to see the Milky way done in a like manner too. Also some of the other neighboring galaxies.

are there any false colour versions of this one floating about by any chance ?

What's the problem with making one?

Hello All

I love the image, its amazing how many are popping up.

Are they Nova or supernova.

There seems to be both.

I assume this process is part of the recycle process.

search and find more.

Primarily, these are H-II regions, which are nebulas containing young or newborn stars, where star formation is taking place. A good example of this in our galaxy is the Orion Nebula. The bubbles are being formed by the powerful stellar winds of hot, young stars blowing the material of the nebula away from them.

Hello qev

The size of the clouds would inidcate
either
Stellar winds
Dwarf nova
Nova
or supernova

What extent do stellar winds have?

Has anyone noticed there seems to be some of the gas forming clouds that make a curved line through the center of the LMC? Not that it seems to have any significance; but is kind of a curious thing.

Hello All

The Tarantula Nebula

http://antwrp.gsfc.nasa.gov/apod/ap060106.html

The spindly arms of the Tarantula Nebula surround NGC 2070, a cluster that contains some of the intrinsically brightest, most massive stars known. Intriguing details of the nebula's core can be seen in this remarkable skyscape, a composite of 31 hours of exposure time. This cosmic Tarantula also lies near the site of the closest recent supernova.

Ionized by energetic starlight, a hydrogen atom emits the characteristic red H-alpha light as its single electron is recaptured and transitions to lower energy states. As a result, this image of the LMC seems covered with shell-shaped clouds of hydrogen gas surrounding massive, young stars. Sculpted by the strong stellar winds and ultraviolet radiation, the glowing hydrogen clouds are known as H II (ionized hydrogen) regions

.

So we do have mostly Nova and some supernova.
