Dead star comes back to life like a zombie
SPACE – A study out of Johns Hopkins University shows, a star declared dead more than 12,000 years ago, isn’t.
The zombie star is Abell 30. It’s several thousand light years away and in the middle of planetary nebula, that’s a cloud of interstellar gas and dust.
Astronomers were able to spot zombie characteristics, like helium bursting from the star’s core using NASA’s Hubble Telescope and the Chandra X-ray Observatory.
The study which appears in Astrophysical Journal concludes, the star came back to life about 800 years ago. This rebirth is fascinating to scientist for several reasons.
- It’s a rare occurrence.
- It’s difficult to spot.
- Abell 30 shows what may happen to our sun, in five billion years, give or take or a billion.
