Looking its best ever is the star cluster NGC 2203, here imaged by the NASA/ESA Hubble Space Telescope. Aside from its dazzling good looks, this cluster of stars contains lots of astronomical treats that have helped astronomers puzzle together the lifetimes of stars.

A main-sequence star is a star in the longest period of its life, when it burns fuel steadily like the sun. Our sun’s fuel will run out in approximately 6 billion years, and it will then move on to the next stage of its life when it becomes a red giant. Astronomers studying NGC 2203, which contains stars that are roughly twice as massive as our sun, found that rotation rates might be a factor as to why some of the stars stay longer than usual in this main-sequence phase of their life.

NASA’s Goddard Space Flight Center is home to the nation’s largest organization of combined scientists, engineers and technologists that build spacecraft, instruments and new technology to study the Earth, the sun, our solar system, and the universe.

Named for American rocketry pioneer Dr. Robert H. Goddard, the center was established in 1959 as NASA’s first space flight complex. Goddard and its several facilities are critical in carrying out NASA’s missions of space exploration and scientific discovery.
