Sodium and rocky material in the dead star’s atmosphere create its unusual chartreuse color. [306][307] Black holes reshape cosmic scenes - Chandra observations explain a treble-clef-shaped radio structure, while separate research points to an exceptionally close pair of feeding supermassive black holes in the early universe. [190][317] Moon rocks and Mars miles - Chang’e-6 samples offer a possible explanation for the Moon’s two contrasting faces, while Perseverance has set a new off-world driving-distance record on Mars. [106][163] Satellites tackle problems on Earth - A major controlled test validated dedicated methane-detecting satellites, and the United Kingdom selected ClearSpace for a mission intended to remove two dead satellites from orbit. [218][219][42] Dragon arrival and Neutron delay - A Dragon cargo spacecraft is arriving at the International Space Station with science and new solar arrays, while Rocket Lab has delayed the first Neutron launch until 2027. [249][52] Episode Transcript The first green dead star We begin with a star that would look genuinely green to human eyes. Researchers studying nearby white dwarfs—the dense remains left after stars like the Sun reach the end of their lives—modeled how their light would appear at close range. Most would still look broadly white, but a few contain extra elements that dramatically alter their color. The standout is WD J1330 plus 6435. It has absorbed rocky material from the planetary system that once surrounded it, adding calcium, lithium, and sodium to its atmosphere. The sodium removes much of the yellow, orange, and red light, leaving what researchers describe as a ghostly chartreuse glow. This is believed to be the first credible example of a star that would appear green. The finding is more than a color curiosity. Material in a white dwarf’s atmosphere can reveal what happened to the planets, moons, and asteroids that survived the death of its original star. In this case, the unusual color is e
