description Fleming 1 Overview
Fleming 1 is a planetary nebula located roughly 10,000 light-years away in the southern constellation of Centaurus. Discovered by astronomer Williamina Fleming, it is most notable for its complex, symmetric bipolar outflows of gas. These knotted jets are believed to be the result of precessing forces generated by a close binary star system at the nebula's center, consisting of two white dwarfs orbiting one another. As the central stars shed their outer layers, the orbital dynamics shape the ejected material into the observed three-dimensional structure.
help Fleming 1 FAQ
Where is Fleming 1 located?
Fleming 1 is a planetary nebula in the constellation Centaurus, roughly 10,000 light-years from Earth. It is visible in the southern sky rather than near the familiar northern constellations.
Why is Fleming 1 famous among planetary nebulae?
Its most striking feature is a pair of highly symmetric, knotted bipolar jets. Those outflows extend in opposite directions and are thought to be linked to interacting stars at the nebula's center.
Who discovered Fleming 1?
Fleming 1 was discovered by Williamina Fleming, a pioneering astronomer who worked at the Harvard College Observatory. The nebula is one of the objects named after her astronomical discoveries.
Is Fleming 1 a planet or a planetary nebula?
It is not a planet. A planetary nebula is a glowing shell of gas expelled by a dying star, and Fleming 1 is especially unusual because of its organized bipolar outflows.
