Hubble observes the hidden depths of NGC 2903 | Astronomy



The NASA / ESA Hubble Space Telescope produced an unprecedented image of the central region of the spiral galaxy NGC 2903.

Few people in the universe are as iconic as the spiral galaxy.

These celestial objects that dominate the spotlight combine spinning and rotating arms with dispersions of sparkling stars, glowing gas gusts and dark bands of cosmic dust, creating truly stunning scenes.

The spiral galaxy NGC 2903 is located approximately 30 million light years away in the constellation Leo.

Also known as LEDA 27077, UGC 5079 and IRAS 09293 + 2143, the galaxy was discovered by the British astronomer William Herschel on November 16, 1784.

The NGC 2903 has an extremely high speed of creation of new stars in its central region.

It was studied as part of a Hubble survey of central regions of about 145 nearby galaxies.

The study aimed to help astronomers better understand the relationship between black holes hiding in galaxy nuclei and the bulge of stars, gas and dust in the center of the rugby ball galaxy – as seen in this image from NGC 2903.

The image is a composite of separate exhibits acquired by Hubble's Advanced Camera for Surveys (ACS).

Two spectral filters – F658W and F814W – were used to sample various wavelengths.

The color results from assigning different shades to each monochrome image associated with an individual filter.
