| Description |
ARTIST ILLUSTRATION Sand…coarse, rough, gets everywhere. We may have found it on VHS 1256 b, a Tatooine-like world orbiting twin suns. Among other molecules, Webb detected silicate dust grains of varying sizes in its atmosphere. The larger grains may be like very hot, small sand particles. VHS 1256 b is about 40 light-years away and completes an orbit around its two stars every 10,000 (Earth) years. Despite the planet being 4 times farther from its stars than Pluto is from our Sun, the upper part of its atmosphere gets as hot as 1,500 degrees F (830 degrees C). The planet’s churning atmosphere constantly brings hotter material up and pushes colder material down over its 22-hour day, resulting in extremely dramatic brightness changes. In fact, VHS 1256 b is the most variable planetary-mass object known to date! No other telescope has ever identified so many features at once for a single target. With just a few hours of observations, Webb's provided enough for astronomers to keep learning about VHS 1256 b in the coming months and even years.

The planet is about 40 light-years away and orbits two stars that are locked in their own tight rotation. Its clouds, which are filled with silicate dust, are constantly rising, mixing, and moving during its 22-hour day. Image description: Illustration of a planet. The background is black, darkest at the left edge, with light streaming from a small pair of stars at right. Stars are spread throughout, appearing as pinpricks of light. The planet is at left, taking up about a quarter of the image. It is a deep orange, and contains several stripes. The brightest stripes lie in the top and bottom thirds. A small circular oval representing a large storm appears toward the top left, similar to the Great Red Spot on the planet Jupiter. The right edge of the planet (the side facing the star) is lit, while the rest is largely in shadow. |
