30 Doradus: A Massive Star-Forming Region [Ultra HD]

30 Doradus (the Tarantula Nebula) is a very bright and active star-forming region outside of the Milky Way galaxy, at 160,000 light-years away. “30 Dor” is home to the central star cluster NGC 2070, including the most active region, R136, which appears in the central-right area of the image. R136 is a few million years old and contains many thousands of young stars, including several of the largest known. The bright blue stars shine out of the cleared cavity that is excavated by stellar winds. The redder stars are still partially embedded in the cloud material, seen in shadow except where illuminated by the cavity stars. In the infrared view the embedded stars shine more clearly through the intervening cloud material. ... Read More إقرأ المزيد | Share it now!

The Orion Nebula: Visible and Infrared Views [UltraHD]

This sequence uses infrared (Spitzer) and visible (Hubble) images to reveal the formation of stars within a large cloud of hydrogen gas and dust. The warm gas lights up in the infrared view as red, and the hydrocarbon dust appears in green. The starlight from young stars appears in blue. The flood of starlight provides extra illumination throughout the dusty environment and in front of the cloud. The threads of gas, reminiscent of clouds on Earth, are compressed and pushed into knots by the winds from forming stars throughout the region. The clouds appear as shadows in this visible-light view. However, in areas where the gas has mostly been cleared or thinned, glowing cavities can be seen inside these cocoons. The combined view hints at the nebula’s complex three-dimensional structure.... Read More إقرأ المزيد | Share it now!
