Explanation:
What unexpected things do you see when you look up at the night sky? Today’s image resembles an
abstract painting,
with large swaths of color strewn across a cosmic canvas seemingly without design. Despite the image’s abstract nature, the
human mind finds patterns,
identifying a large claw reaching up towards a floating bubble. Embedded within these seemingly random structures are the physical laws that govern
how light and matter interact.
The
Claw
(Sh2-157) and
Bubble
(NGC 7635)
Nebulae glow
colors that are mapped
to the yellow and blue shown, indicating the presence of hydrogen and oxygen
ionized by the intense light emitted from stars
several times the mass of the Sun. This image depicts both the chaos and structure of astronomical processes, showing that a common thread between art and science is
to look for the unexpected.
