🥹 'Today represents an exciting new chapter in the exploration of our universe...'
The James Webb Space Telescope's NIRSpec instrument was used to study a region close to the center of our Milky Way galaxy. A test of the telescope's multi-object spectroscopy mode packed more than 200 spectra in a single exposure. Each horizontal stripe represents a spectrum that scientists will be able to analyze to better understand the composition and properties of the gas found between the stars in this region.
While it's JWST's images that space fans might be most excited to see, scientists are also eager for images like this, an image taken during late-stage testing of the observatory's NIRSpec instrument. NIRSpec is a spectrograph, which means it splits up light from any given source by wavelength. The result is a chemical barcode that scientists can use to identify what celestial objects are made of. NIRSpec is particularly powerful because it can gather
from many different sources at once: Each horizontal line in the test image represents a separate object.
