NGC 2903 - Barred Spiral Galaxy
NGC 2903 is an isolated barred spiral galaxy in the
constellation of Leo, positioned about 1.5° due south
of Lambda Leonis.
Historyu
It was discovered by German-born astronomer William Herschel,
who cataloged it on November 16, 1784. He mistook it as a
double nebula, as did subsequent observers, and it wasn't until
the nineteenth century that the Third Earl of Rosse resolved
into a spiral form.
This galaxy is located about 30 million light-years away from Earth
and is a member of the Virgo Supercluster.
