The rotation of the image on the sky with respect to the north pole of the celestial sphere.The James Webb Space Telescope may have spotted theoretical "dark stars" glowing in the distant past, according to a new study. The date and time the release content became public.Ī brief description of the methods used to convert telescope data into the color image being presented. The primary individuals and institutions responsible for the content. The camera filters that were used in the science observations. The date(s) that the telescope made its observations and the total exposure time. The science instrument used to produce the data. "PI" refers to the Principal Investigator. Science Team: The astronomers who planned the observations and analyzed the data.Proposal: A description of the observations, their scientific justification, and the links to the data available in the science archive.The physical size of the object or the apparent angle it subtends on the sky. Interstellar distances can also be measured in parsecs. Solar system are usually measured in Astronomical Units (AU). The physical distance from Earth to the astronomical object. One of 88 recognized regions of the celestial sphere in which the object appears. Right ascension – analogous to longitude – is one component of an object's position.ĭeclination – analogous to latitude – is one component of an object's position. Credits ImageĪ name or catalog number that astronomers use to identify an astronomical object. The lighter-colored gas surrounding S1 consists of polycyclic aromatic hydrocarbons, a family of carbon-based molecules that are among the most common compounds found in space.įor more detail on what is happening where in Webb’s image of Rho Ophiuchi, watch the video tour and read the press release. The heftiest in this image is the star S1, which appears amid a glowing cave it is carving out with its stellar winds in the lower half of the image. The young stars at the center of many of these disks are similar in mass to the Sun, or smaller. Some stars display the telltale shadow of a circumstellar disk, the makings of future planetary systems. Jets bursting from young stars crisscross the image, impacting the surrounding interstellar gas and lighting up molecular hydrogen, shown in red. It is a relatively small, quiet stellar nursery, but you’d never know it from Webb’s chaotic close-up.
The subject is the Rho Ophiuchi cloud complex, the closest star-forming region to Earth.

The first anniversary image from NASA’s James Webb Space Telescope displays star birth like it’s never been seen before, full of detailed, impressionistic texture.
To the left of this star is a more wispy, indistinct region, like this star is also beginning to clear out space around itself like the one at the center of the dusty cave below. At the top center of the image, a star displays another, larger pinched dark shadow, this time vertically. The image’s largest jets of red material emanate from within this dark cloud, thick and displaying structure like the rough face of a cliff, glowing brighter at the edges. The dark shadow of the cloud appears pinched in the center, with light emerging in a triangle shape above and below the pinch, revealing the presence of a star inside the dark cloud. A dark cloud sits at the top of the arch of the glowing dust cave, with one streamer curling down the right-hand side. Smaller stars are scattered around the image. Above the arched top of the dust cave three groupings of stars with diffraction spikes are arranged. The dust of the cave structure becomes wispy toward eight o’clock, trailing off and allowing stars and distant galaxies to show through. Red dual opposing jets coming from young stars fill the darker top half of the image, while a glowing pale-yellow, cave-like structure is bottom center, tilted toward two o’clock, with a bright star at its center.
