The phrase "a star formation" is correct and usable in written English.
It can be used in contexts related to astronomy, specifically when discussing the process by which stars are born or grouped together in space.
Example: "The telescope captured stunning images of a star formation in the Orion Nebula."
Alternatives: "a stellar formation" or "a constellation of stars".
A star formation region about 5,500 light years from Earth.
Star formation will stop after a relatively small number of stars have formed within a star formation region.
This video begins with optical observations of the nebula M78, a star formation region located in our galaxy about 1300 light years from earth.
These new data and published results enable the authors to discuss the nature of the embedded stellar population and to calculate a star formation efficiency of 34% - 47% for the central core of the cloud.
(frac {d_{text {max}}}{|E|} = 1) indicates a star formation.
(frac {d_{text {max}}}{|E|}) will approach one as the network approaches a star formation.
The abundance pattern of the galaxy is consistent with enrichment exclusively by core-collapse supernovae and with a star-formation timescale of 0.1 to 0.5 billion years characteristics that are similar to population II stars in the Milky Way.
The abundance pattern of the galaxy is consistent with enrichment exclusively by core-collapse supernovae, and a star-formation timescale of 0.1 to 0.5 billion years, making it one of the most vigorous star-forming galaxies in the Universe.
Clusters containing a den or rendezvous site, that is sites where cubs were moved to and placed during the summer (Murie 1944; Jędrzejewski et al. 2001), were identified by a star-formation movement pattern of the adult wolves and were not visited in the field until at least 1 week after wolves had left the area.
This suggests that M31 once experienced a great star formation phase, but is now in a relative state of quiescence, whereas the Milky Way is experiencing more active star formation.
One location is arranged in a "Six Star" formation while the other can be categorized as a "Lazy W" by a US Army Field Manual.
