WASHINGTON : NASA on Wednesday released an image obtained by the James Webb Space Telescope of the Rho Ophiuchi cloud complex, the closest star-forming region to Earth, as the U.S. space agency marked one year since it unveiled the telescope's first scientific results.
The Rho Ophiuchi image was an example of that, showing a nebula - a humongous cloud of interstellar gas and dust that serves as a nursery for new stars - located in our Milky Way galaxy roughly 390 light years from Earth. A light year is the distance light travels in a year, 5.9 trillion miles ."Here, we see how new suns are forming, along with planet-forming disks appearing as small dark silhouettes. These are very similar to what we think the solar system looked like more than 4.
The image, obtained in March and April of this year, shows how the jets of material emanating from young stars affect the surrounding gas and dust while lighting up molecular hydrogen. In one part of the image, a star is seen inside a glowing cave that its stellar winds carve out in space. Since becoming operational, Webb has revealed the existence of the earliest-known galaxies and black holes. It has observed large and mature but remarkably compact galaxies teeming with stars that had formed within a few hundred million years of the Big Bang event that marked the beginning of the universe about 13.8 billion years ago - far sooner than scientists had considered possible.
