Greetings from the "Hubble": Treasures Large Magellanic Cloud

To the Large Magellanic Cloud (LMC), a satellite Milky Way, about 200 thousand light years. In a slow, long dance around our galaxy huge cloud of gas is compressed to form new stars, which, in turn, illuminated gas clouds, giving a riot of color to the eye (with the help of the space telescope "Hubble", of course).

LMC packed active regions of star formation. Of the Tarantula Nebula (brightest stellar nursery in our cosmic neighborhood) to the subject LHA 120-N 11 (part of which fit in this picture) — for this small irregular galaxy and scattered many glowing nebulae, which are a sure sign of the birth of new stars.

Cloud is in an ideal position to observe, and in particular to study the processes involved in the formation of stars. First, it is located in the sky far away from the plane of the Milky Way, and it does not overshadow or nearest star, no dust in the galactic center. Second, a stone's throw to him (less than one-tenth of the distance to the Andromeda galaxy, our nearest spiral), and brought it to us to "face."

LHA 120-N 11 (or N11) — particularly bright area LMC. It consists of several related areas of gas and star formation. Star clusters NGC 1769 (in the center of the image) and NGC 1763 — the most prominent of them.

In the center of the dark "finger" dust covers greater rigor of the light. While the nebula are composed mainly of hydrogen, the simplest element and widespread in the universe, dust clouds contain a more severe and complex elements that go into the creation of rocky planets like Earth. Smaller, than the home, the interstellar dust (it looks more like smoke) is the material ejected dead stars.

The data that were the basis of the image is found and processed Josh Lake, a school teacher of astronomy from the State of Connecticut (USA), who took part in the competition Hubble's Hidden Treasures and won. Participants are invited to this event to dig into the archives of boundless "Hubble" and look where that has not turned into a beautiful picture.

Winning work was the image that emphasizes the contrast between the emission of hydrogen and nitrogen in N11. This image — the fruit of further proceedings, Mr. Lake with filters in blue, green and near-infrared parts of the spectrum.

Prepared according to NASA.
