- Star Types - Science@NASA
Scientists call a star that is fusing hydrogen to helium in its core a main sequence star Main sequence stars make up around 90% of the universe’s stellar population They range in luminosity, color, and size – from a tenth to 200 times the Sun’s mass – and live for millions to billions of years
- The Lives, Times, and Deaths of Stars - NASA Science
These and planetary nebulae from low-mass stars are the sources of many of the elements we find on Earth Their dust and gas will one day become a part of other stars, starting the whole process over again That’s a very brief summary of the lives, times, and deaths of stars
- Star Lifecycle - Science@NASA
Groups of stars make up galaxies, while planets and ultimately life arise around stars Although stars have been the main topic of astronomy for thousands of years, we have begun to understand them in detail only in recent times through the advent of powerful telescopes and computers
- Hubble Snapshot Captures Life Cycle of Stars - Science@NASA
This picture nicely illustrates the entire stellar life cycle of stars, starting with the Bok globules and giant gaseous pillars (evidence of embryonic stars), followed by circumstellar disks around young stars, and progressing to aging, massive stars in a young starburst cluster
- Hubble Skymap - NASA Science
The Hubble Skymap puts the night sky at your fingertips any time of day Roam the Milky Way to find a selection of galaxies, stars, nebulae and more, and click for a Hubble's-eye-view of each object To explore the skymap, scroll, double click, or pinch swipe to zoom in and out
- Multiple Star Systems - Science@NASA
These multiple star systems come in a stunning variety of flavors: large, hot stars orbited by smaller, cooler ones; double stars orbited by planets; pairs pulsing with X-rays as one sheds material that is devoured by the other; systems with as many as seven stars in a complex gravitational dance
- Solar System Exploration - Science@NASA
The solar system has one star, eight planets, five dwarf planets, at least 290 moons, more than 1 3 million asteroids, and about 3,900 comets
- New Visualization From NASA’s Webb Telescope Explores Cosmic Cliffs
This glittering realm of star birth is the subject of a new 3D visualization derived from the Webb data The visualization, created by NASA’s Universe of Learning and titled “Exploring the Cosmic Cliffs in 3D,” breathes new life into an iconic Webb image
