Star nursery flourish

Star nursery flourish

OmegaCAM on the Very Large Telescope received this bright view of the star nursery SH2-29. The giant picture allows you to view a variety of astronomical phenomena, including dust and gas clouds, reflecting, absorbing and emitting light of hot children's stars.

An amazing view of the SH2-29 managed to get the OmegaCAM on the Very Large Telescope. The scale of coverage allowed fixing various astronomical objects, including dust and gas clouds. They reflect, absorb and emit the glow of hot young stars of the nebula.

SH2-29 is an interstellar cloud of ionized gas filled with sections of stellar birth. It is 5,500 light-years distant from us and lives in the territory of Sagittarius. The star section of NGC 6559 (a nebula in the center of the frame) is also huddled here.

The central nebula is the brightest feature of SH2-29. It extends only a few light years, but demonstrates the chaos created by the emerging stars. Objects in the picture no more than 2 million years, and they release high-energy radiation fluxes. This energy glows the surrounding dust and gas. One can notice a cavity carved out by an energetic binary star system. The cavity expands, due to which interstellar material accumulates and creates a red arcuate line.

When the stellar UV light attacks interstellar dust and gas, the energy makes them shine even brighter. The diffuse red luminescence is created by the emission of gaseous hydrogen, and the blue flickering is the reflection and scattering of small dust particles. You can see and absorption. Dust areas block the light and block the stars from the earth observation.

SH2-29 is a unique area to explore, because it is replete with physical phenomena. It is worth remembering that the region is filled with young massive stars. They quickly die and explode in the form of supernovae. That is, after tens of millions of years, this image will disappear, leaving an open cluster.

OmegaCAM, which is capable of covering celestial areas 300 times more than Hubble’s capabilities allow, was used for the observation. But the most valuable thing is the ability of the camera to capture the red spectral line H-alpha (formed when the electron inside the hydrogen atom loses energy).
