One of the most incredible things about the universe is its inherent ability to still throw so many surprises our way. One of those mysteries can be found in the form of “blue stragglers,” hot, high-mass, blue-white stars that burn fiercely loonnng past their expiration date. Could the mechanism driving their survival be a little bit of interstellar vampirism? Maybe.

Could a star die twice?
When stars of mass similar to our sun die, they eject much of the outer atmosphere into space, leaving a hot smaller core that will become a white dwarf. The shells of the ejected material resemble planets, so they are called planetary nebulae. Studying the motion and appearance of those can tell scientists a lot.
KjPn 8 is a peculiar kind of planetary nebula, actually being a planetary nebula inside another one. It’s a rare one of its kind (with only another one in the northern hemisphere) and its central star was finally revealed in 2000 by the Hubble Space Telescope.
