Few residents of the Universe are as iconic as the spiral galaxy.
These celestial objects that hang out in the spotlight combine swirling arms with glittering stars, sparkling gas flares and dark corridors of cosmic dust, creating truly impressive scenes.
The spiral galaxy NGC 2903 is located about 30 million light-years away from the constellation Leo.
Also known as LEDA 27077, UGC 5079 and IRAS 09293 + 2143, the galaxy was discovered by the British astronomer of German origin William Herschel on November 16, 1784.
NGC 2903 has an extremely high speed to create new stars in its central region.
It has been studied in the context of a Hubble study of central regions of about 145 nearby galaxies.
The study aimed to help astronomers better understand the relationship between the black holes that hide at the heart of galaxies and the bulge of stars, gas and dust-shaped rugby ball in the center of the galaxy, as in this image NGC 2903.
The image is a composite of distinct exposures acquired by Hubble's Advanced Camera for Surveys (ACS).
Two spectral filters – F658W and F814W – were used to sample different wavelengths.
The color results from assigning different shades to each monochromatic image associated with an individual filter.
