The James Webb Space Telescope on Tuesday unveiled sublime images of the Tarantula Nebula, a region of the cosmos where stars are born at a frantic pace, and whose pictures will deepen scientific knowledge of star formation.
Nicknamed for the shape of its clouds of gas and dust, the Tarantula Nebula is located “just 161,000 light-years away,” NASA said in a statement. It is the largest and brightest star-forming region of the entire group of galaxies near ours, and is home to the hottest and most massive stars known. Although this nebula has therefore long been a target of choice for scientists studying the process of star formation, these images reveal new details, including thousands of young stars hitherto invisible to the eyes of previous telescopes. In the center of the image taken by the NIRCam instrument, which operates in the near infrared, is a cluster of very bright young blue stars. Another instrument, NIRSpec, allowed him to distinguish a star just emerging from its pillar of dust, while maintaining a cloud around it — a stage in its formation that could not have been observed. without the incredible abilities of James Webb. Researchers previously thought that this star was actually older, and at a more advanced stage. “Star-forming regions within our Milky Way don’t produce stars at the same breakneck rate as the Tarantula Nebula, and have different chemical compositions,” NASA explained.
