This is the last death gasp of a dying star.
NASA's Hubble Telescope captured this telling image of U Camelopardalis (or U Cam for short), a red giant star in the Camelopardalis constellation, as it became increasingly unstable.
According to NASA, as a carbon star -- U Cam has more carbon than oxygen in its atmosphere -- an eruption like this happens every few thousand years when its core begins to fuse.
The celestial fireworks occur on a much smaller level than this image might suggest. Proportionally, the actual star is just a tiny fraction of what's displayed in this image.
U Cam itself is much smaller than it appears in this Hubble image. In fact, the star would easily fit within a single pixel at the center of the image. Its brightness, however, is enough to saturate the camera's receptors, making the star look much larger than it is.
As UPI reports, the ejected gas bubble, which forms the faint outermost shell, is almost perfectly spherical.
But U Cam is still a few centuries from puttering out for good, though that's virtually nothing in astronomical terms, MSNBC notes.
Our own sun is still billions of years from turning into a red giant itself, and ejecting material just like this star.
