Here’s a beautiful picture of the Triffid Nebula, a stellar region located within our Milky Way Galaxy.
James Webb, but not only. The legendary Hubble Space Telescope We are now accustomed to grandiose images of the universe. In this article we will trace the history of one of the most amazing nebulae ever imaged by Hubble. This is the Triffid NebulaA star-forming region located within our Milky Way galaxy. It’s called the Trifid because the nebula is covered in three bands of interstellar dust, giving it a triangular appearance. Trifid is located about 9,000 light-years (2,700 parsecs) from Earth, in the direction of the constellation Sagittarius.
What do we know about this nebula?
This new image from the Hubble Space Telescope provides a close-up view of the center of the Trifid Nebula. Near the intersection of the dust bands, a group of bright, massive, newly formed stars can be seen. These stars, which astronomers classify as belonging to the hottest and bluest “O” type of stars, emit a stream of stars UV Which affects the evolution of the surrounding nebula. Many astronomers who study nebulae like Trifid focus their research on the ways in which star formation waves move through these regions.
Oxygen evaporates into space
The bright O-type star cluster shines at the center of the Triffid A dense column of gas and dust, which you can see to the right of the center of the image, producing a bright edge on the side facing the stars. At the upper left end of this column is a complex filamentous structure. This structure has a bluish color because it consists of glowing oxygen that evaporates into space. Star formation no longer occurs in the immediate vicinity of a large cluster of bright O-type stars, because their intense radiation has swept away the gas and dust that make up the stars.
