Star-forming filaments

Post by Dragon on Tue Mar 27, 2018 1:25 pm

The plane of the Milky Way is rich in star-forming regions, such as the one pictured in this stunning scene by ESA's Herschel space observatory. To the far-infrared eye of Herschel, this region reveals an intricate network of gas filaments and dark bubbles interspersed by bright hotspots where new stars come to life.

The cooler regions, which emit light at longer wavelengths, are displayed in a red-brownish colour. Hotter areas, where star formation is more intense, shine in blue and white tones. Some areas are particularly bright, suggesting a number of luminous, massive stars are forming there.

Particularly striking is the chaotic web of gas filaments we see in this scene.

This video takes a close-up look at a huge image of part of the southern constellation of Norma (The Carpenter’s Square) where wisps of crimson gas are illuminated by rare, massive stars that have only recently ignited and are still buried deep in thick dust clouds. These scorching-hot, very young stars are only fleeting characters on the cosmic stage and their origins remain mysterious. The vast nebula where these giants were born, known as RCW 106, is captured here in fine detail by ESO’s VLT Survey Telescope (VST), at the Paranal Observatory in Chile.

As the universe expanded, dark matter became a web that stretched across space. It pulled in normal matter to create galaxies.
