description NGC 249 Overview
NGC 249 is an emission nebula in the constellation Tucana, located within the Small Magellanic Cloud. Its designation comes from the New General Catalogue, a standard astronomical catalog of deep-sky objects, and the object is also included in surveys of nebular features in the galaxy. It is of interest to astronomers studying ionized gas, star-forming regions, and the structure of a nearby dwarf galaxy.
help NGC 249 FAQ
Where is NGC 249 located?
It lies in the constellation Tucana, inside the Small Magellanic Cloud, a satellite galaxy of the Milky Way roughly 200,000 light-years away. That makes it a target for southern-hemisphere observers.
What is NGC 249?
It is an emission nebula, a cloud of gas glowing because it is ionized by hot young stars. Its designation comes from the New General Catalogue, compiled by John Louis Emil Dreyer and published in 1888.
Can NGC 249 be seen with a backyard telescope?
The nebula itself is faint and small, mainly a target for long-exposure imaging through larger telescopes. However, the Small Magellanic Cloud that hosts it is easily visible to the naked eye from the Southern Hemisphere.
Has NGC 249 been imaged by the Hubble Space Telescope?
Yes, Hubble has captured NGC 249, showing its glowing bubble of ionized gas in detail. Such observations of nebulae inside the Small Magellanic Cloud help astronomers study star formation in a nearby galaxy.
