Aerosols and hydrocarbons in the atmosphere of a white dwarf planet
Abstract Most stars, including our Sun, will one day evolve into red giants and, subsequently, white dwarfs. Several planet candidates have recently been identified orbiting white dwarfs1,2,3,4, demonstrating that planets can survive the stellar post-main-sequence stage intact. Little is known about the atmospheric composition of post-main-sequence planets, with the most evolved transiting planets with atmospheric detections so far orbiting subgiants5,6.

Letters: Closed primary would encourage extremists, and maybe that's the point Original
Regarding Gov. Jeff Landry's desire to switch to closed primaries, his motivation is obvious. In closed primaries, the more extreme candidates tend to prevail because more extreme party members tend to show up at the polls. Candidates don't have to appeal to moderates, members of other parties, or independents.
Optical properties of organic haze analogues in water-rich exoplanet atmospheres observable with JWST - Nature Astronomy
Abstract The James Webb Space Telescope (JWST) has begun its scientific mission, which includes the atmospheric characterization of transiting exoplanets. Some of the first exoplanets to be observed by JWST have equilibrium temperatures below 1,000 K, which is a regime where photochemical hazes are expected to form.
'Teenage' Jupiter may hold the secret of how planets form
In the past 20 years, thousands of planets have been discovered orbiting other stars. Far from resembling families of planets like Earth and its companions, most of these discoveries have made our solar system look like the odd one out. But now astronomers have announced a new exoplanet that looks surprisingly familiar. The exoplanet, 51 Eridani b, looks a lot like Jupiter – or at least the way we think Jupiter looked when it was much younger.
Saturn | Facts, Size, Temperature, Atmosphere, Color, Rings, & Moons
The Italian astronomer Galileo in 1610 was the first to observe Saturn with a telescope. Although he saw a strangeness in Saturn’s appearance, the low resolution of his instrument did not allow him to discern the true nature of the planet’s rings. Saturn orbits the Sun at a mean distance of 1,427,000,000 km (887 million miles). Its closest distance to Earth is about 1.2 billion km (746 million miles), and its phase angle—the angle that it makes with the Sun and Earth—never exceeds about 6°.
