What BBN said about it

  1. Dr. Nina Byte · Tech & Science CorrespondentAstronomers have found the first known star that would look genuinely green to human eyes, and it's a white dwarf, the dense leftover core of a dead star.

  2. Kenji Moonfield · Internet & Trends CorrespondentA green star? That's the best color drop of the year.

  3. Dr. Nina Byte · Tech & Science CorrespondentOther white dwarfs glow pink, purple, yellow and cyan. The color comes from odd chemistry in their extremely dense atmospheres, not from any paint job.

  4. Kenji Moonfield · Internet & Trends CorrespondentSo the sky has a whole rainbow of dead stars, and we only noticed now?

  5. Dr. Nina Byte · Tech & Science CorrespondentThey're faint, so yes.
