Stars - NASA Science
WEBStars are giant balls of hot gas – mostly hydrogen, with some helium and small amounts of other elements. Every star has its own life cycle, ranging from a few million to trillions of years, and its properties change as it ages.

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 […]

WEBFeb 7, 2024 · Smaller stars like our sun end their lives by ejecting their outer layers of gas into space over the course of about 10,000 years, leaving behind the star’s hot core — a white dwarf. Radiation from the white dwarf causes the gas to glow, creating a unique and beautiful formation called a planetary nebula.
