Researchers studying white dwarfs say they have identified the first known star that would appear genuinely green to human eyes. The stellar remnant, called WD J1330+6435, is not bright green like a traffic light. Models based on its spectrum indicate a pale, chartreuse glow. The color comes from calcium, lithium and especially sodium in its atmosphere. Those elements probably arrived when the dying star pulled in rocky material left over from its former planetary system. Sodium absorbs part of the orange portion of the star's light, leaving the green tint behind. The result matters beyond its visual novelty. White dwarfs are usually described as white or blue-white, but the study shows that material from destroyed planets can give them a much broader range of colors. In other words, a star's appearance can preserve evidence of what happened to the worlds that once surrounded it. [91][92][93] Webb maps a lopsided atmosphere The James Webb Space Telescope has helped astronomers take a more three-dimensional look at another distant world. WASP-17b is an extremely hot gas giant with a remarkably low density, earning it comparisons to marshmallow. By observing starlight passing through different parts of the planet's atmosphere, researchers reconstructed its shape and found that it is not evenly distributed. One region rises outward like a bulge where powerful winds carry heat toward the cooler night side. That uneven shape agrees with broad predictions about how heat should move around a planet that always presents the same face to its star. The important advance is the ability to move beyond a single, averaged atmospheric reading....
