Astronomy Picture of the Day
Discover the cosmos! Each day a different image or photograph of our
fascinating universe is featured, along with a brief explanation
written by a professional astronomer.

A starfield is dominated by a multi-colored figure 8 in the middle,
titled on a diagonal. The outsides of the nebula appear light colored,
while the inside shows complex structure tinted red and purple. Please
see the explanation for more detailed information.
Planetary Nebula NGC 1514 from Webb

Explanation: What happens when a star runs out of nuclear fuel? For
stars like our Sun, the center condenses into a white dwarf while the
outer atmosphere is expelled into space to appear as a planetary
nebula. The expelled outer atmosphere of planetary nebula NGC 1514
appears to be a jumble of bubbles -- when seen in visible light. But
the view from the James Webb Space Telescope in infrared, as featured
here, confirms a different story: in this light the nebula shows a
distinct hourglass shape, which is interpreted as a cylinder seen along
a diagonal. If you look closely at the center of the nebula, you can
also see a bright central star that is part of a binary system. More
observations might better reveal how this nebula is evolving and how
the central stars are working together to produce the interesting
cylinder and bubbles observed.
