The first-anniversary image launched Wednesday, July 12, 2023, by Space Telescope Science Institute Office of Public Outreach, shows NASA’s James Webb Space Telescope displaying a star delivery prefer it has by no means been seen earlier than, stuffed with detailed, impressionistic texture. The topic is the Rho Ophiuchi cloud advanced, the closest star-forming region to Earth.

NASA on Wednesday launched an image obtained by the James Webb Space Telescope of the Rho Ophiuchi cloud advanced, the closest star-forming region to Earth, because the U.S. area company marked one yr because it unveiled the telescope’s first scientific outcomes.
The Webb telescope, which was launched in 2021 and started accumulating knowledge final yr, has reshaped the understanding of the early universe whereas taking beautiful footage of the cosmos.
The Rho Ophiuchi image was an instance of that, exhibiting a nebula – a humongous cloud of interstellar gasoline and dirt that serves as a nursery for brand spanking new stars – positioned in our Milky Way galaxy roughly 390 mild years from Earth. A lightweight yr is the gap mild travels in a yr, 5.9 trillion miles (9.5 trillion km).
Rho Ophiuchi is barely about 1,000,000 years outdated, a blink of the attention in cosmic time.

“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 4.5 billion years ago,” mentioned astronomer and former Webb challenge scientist Klaus Pontoppidan, who’s now a analysis scientist at NASA’s Jet Propulsion Laboratory.
“As the stars and planetary systems assemble, they blow apart the dusty cocoon from which they formed in violent outbursts, as seen in red jets plowing through the cloud as a boat in water. The Rho Ophiuchi core is completely obscured by huge amounts of dust, so it is essentially invisible to telescopes working in visible light, like the Hubble telescope. Yet, Webb peers through the dust to reveal the young stars within, showing the very first stages in the life of every star,” Pontoppidan added.
The image, obtained in March and April of this yr, shows how the jets of fabric emanating from younger stars have an effect on the encompassing gasoline and dirt whereas lighting up molecular hydrogen. In one a part of the image, a star is seen inside a glowing cave that its stellar winds carve out in area.
“You see an almost impressionistic nebula crowned by three bright young stars on the top. We were surprised by the size and detail of the jets and outflows,” Pontoppidan mentioned.

Since changing into operational, Webb has revealed the existence of the earliest-known galaxies and black holes. It has noticed giant and mature however remarkably compact galaxies teeming with stars that had shaped inside just a few hundred million years of the Big Bang occasion that marked the start of the universe about 13.8 billion years in the past – far prior to scientists had thought of potential.
“Some would say there are few parts of astrophysics that have not been touched by Webb in one way or another. Prominent results include the discovery of new galaxies and black holes in the early universe and new views into exoplanetary atmospheres. The Rho Ophiuchi images shows how Webb gives us a new window into the formation of stars and planets,” Pontoppidan mentioned.
The orbiting observatory was designed to be way more delicate than its Hubble Space Telescope predecessor. Webb seems to be on the universe primarily within the infrared, whereas Hubble has examined it primarily at optical and ultraviolet wavelengths. Webb is in a position to take a look at better distances and thus farther again into time than Hubble.
“In just one year, the James Webb Space Telescope has transformed humanity’s view of the cosmos, peering into dust clouds and seeing light from faraway corners of the universe for the very first time,” NASA Administrator Bill Nelson mentioned in an announcement. “Every new image is a new discovery, empowering scientists around the globe to ask and answer questions they once could never dream of.”
