The Hubble Telescope captured a dazzling new photograph of a spiral galaxy, NGC 2903.
NGC 2903 is part of the constellation Leo, located about 30 million light-years away from Earth. NASA has used the powerful orbital telescope to explore with more than 100 other disk galaxies in the region.
Spiral galaxies comprise the majority of galaxies in space over 75%. Our own galaxy, the Milky Way, was considered until the 1960s, when it was reclassified as a barred spiral (a spiral galaxy with a separate center bar as well as spiral arms). The arms of spiral galaxies are full of stars (and solar systems) as well as dust and cosmic gases.
NASA has a particular fascination for black holes right now, and spiral galaxies often contain singularities – another word for "black hole" – somewhere near the center. Hubble's investigation of disk galaxies aims to explore the relationship between these black holes and their local galaxies.
