APOD: Flight Through the Orion Nebula in... (2021 Jul 07)

Explanation: What would it look like to fly into the Orion Nebula? The exciting dynamic visualization of the Orion Nebula is based on real astronomical data and adept movie rendering techniques. Up close and personal with a famous stellar nursery normally seen from 1,500 light-years away, the digitally modeled representation based is based on infrared data from the Spitzer Space Telescope. The perspective moves along a valley over a light-year wide, in the wall of the region's giant molecular cloud. Orion's valley ends in a cavity carved by the energetic winds and radiation of the massive central stars of the Trapezium star cluster. The entire Orion Nebula spans about 40 light years and is located in the same spiral arm of our Galaxy as the Sun.

Fascinating video, and I particularly loved seeing how stars sort of "rise and billow like smoke" from their likely birthplace in the Trapezium region. It is also correct to say that the fertile site of star formation recedes as more and more of the gas is converted into stars.

But I'm disappointed that we didn't get to see the Becklin-Neugebauer infrared source, which is an embedded massive star located to the northwest (upper right) of the Trapezium. Or is that white stuff below the Trapezium stars in the video actually the embedded Becklin-Neugebauer star?

Interesting tour through Orion Nebula; I really enjoyed it! You could see the view turning as the movie progressed; great video! Great infrared view! 8-)
