NGC300 Galaxy at Sculptor
NGC300 is a faint
galaxy in the austral Sculptor constellation.
This galaxy is located at about 6 million light-years away
from Earth. This is a typical spiral galaxy and its plane
is tilted 42° respect to our line of sight.
Its spiral arms show a bluish coloration because in these
areas new stars are being produced, while the central part
with older stars is more yellow.
There are also some reddish spots revealing the places
where the energetic radiations coming from the massive
young stars are heating and ionizing the gases.
