Close-up: Spiral Galaxy NGC 6000 in Scorpius | Hubble

Stars of all ages are on display in this NASA/European Space Agency Hubble Space Telescope picture. This sparkling spiral galaxy is called NGC 6000 and it is located 102 million light-years away in the constellation Scorpius. 

This galaxy has a glowing yellow center and glittering blue outskirts. The colors reflect the average ages, masses and temperatures of the galaxy’s stars. In the heart of the galaxy, the stars tend to be older and smaller. Less massive stars are cooler than more massive stars, and somewhat counterintuitively, cooler stars are redder, while hotter stars are bluer. Farther out along NGC 6000’s spiral arms, brilliant star clusters host young, massive stars that appear distinctly blue.

Hubble collected the data for this image while surveying the sites of recent supernova explosions in nearby galaxies. NGC 6000 has hosted two recent supernovae: SN 2007ch in 2007 and SN 2010as in 2010. Using Hubble’s sensitive detectors, researchers are able to discern the faint glow of supernovae years after the initial explosion. These observations help to constrain the masses of supernova progenitor stars and can indicate if they had any stellar companions. 

By zooming in to the right side of the galaxy’s disc in this image, you may see something else yellow and blue: a set of four thin lines. These are an asteroid in our Solar System. It was drifting across Hubble’s field of view as it gazed at NGC 6000. The four streaks are due to exposures that were recorded one after another with slight pauses in between. These were combined to create this final image. The colors appear this way because each exposure used a filter to collect only specific wavelengths of light, in this case around red and blue. Having these separate exposures is important to study and compare stars by their colors—but it also makes asteroid interlopers very obvious!

Image Description: An oval-shaped spiral galaxy where only the center and lower half is in frame. Its center is mainly golden in color with a white glowing core. Its thick spiral arms are mostly blue, particularly at the outskirts; the colors merge in between. Dark lanes of dust swirl through the center, blocking some of its light. Stars and distant galaxies can be seen around the edges on a black background.
