Stars - NASA Science
WEBAstronomers estimate that the universe could contain up to one septillion stars – that’s a one followed by 24 zeros. Our Milky Way alone contains more than 100 billion, including our most well-studied star, the Sun. Stars are giant balls of hot gas – mostly hydrogen, with some helium and small amounts of other elements.

WEBSep 10, 2024 · NASA’s James Webb Space Telescope has infrared vision that lets us peer through the dusty veil of nearby star-forming region NGC 1333. We can see planetary mass objects, newborn stars, and brown dwarfs; some of the faintest ‘stars’ in this mosaic image are in fact newly born free-floating brown dwarfs …
Webb Snaps Highly Detailed Infrared Image of Actively Forming Stars - NASA
WEBJul 26, 2023 · NASA’s James Webb Space Telescope has captured a tightly bound pair of actively forming stars, known as Herbig-Haro 46/47, in high-resolution near-infrared light. Look for them at the center of the red diffraction spikes, appearing as …
NASA’s Webb Peers into the Extreme Outer Galaxy
WEBSep 12, 2024 · Astronomers have directed NASA’s James Webb Space Telescope to examine the outskirts of our Milky Way galaxy. Scientists call this region the Extreme Outer Galaxy due to its location more than 58,000 light-years away from the Galactic Center. (For comparison, Earth is approximately 26,000 light-years from the center.) A team of scientists used Webb’s NIRCam […]

Where Are New Stars Born? NASA’s Webb Telescope Will …
WEBAug 21, 2019 · Scientists will measure the older stars—stars that live for billions of years, like the Sun. They’ll determine where those stars reside within a galaxy, which will inform them about the past history of star formation. Then they can compare that data to where the new stars are forming.
