The planet, TOI-6894b, is about the size of Saturn but orbits a star just a fifth the mass of our Sun. This challenges long-standing ideas about how big planets form, especially around small stars. Current theories can't fully explain how such a planet could have taken shape. Even more fascinating, this cold planet may have a rare kind of atmosphere rich in methane or even ammonia something we've never seen in an exoplanet before.

New JWST observations with NIRISS reveal a dynamic atmosphere: powerful winds sweep around the planet, shaping mineral clouds as they condense into a bright, white arc on the slightly cooler western side of the dayside. As these clouds move eastward, they evaporate under the intense heat, leaving the eastern dayside with clear skies.

For the first time, researchers compared gases in a still-forming planet's atmosphere to its natal disk. The team found the planet surprisingly was less carbon-rich than the disk. Wed, 18 Dec 2024 13:21:52 EST https://www.sciencedaily.com/releases/2024/12/241218132152.htm https://www.sciencedaily.com/releases/2024/12/241216130034.htm Recent measurements with the James Webb Space Telescope (JWST) cast doubt on the current understanding of the exoplanet Trappist-1 b's nature. Until now, it was assumed to be a dark rocky planet without an atmosphere, shaped by a billion-year-long cosmic impact of radiation and meteorites. The opposite appears to be true. The surface shows no signs of weathering, which could indicate geological activity such as volcanism and plate tectonics. Alternatively, a planet with a hazy atmosphere composed of carbon dioxide is also viable. The results demonstrate the challenges of determining the properties of exoplanets with thin atmospheres.

The star type was uncertain. The team has determined that the star is a white dwarf, a system resembling what our sun-Earth system will look like in 8 billion years. The good news: the planet survived its star's red giant phase, so maybe Earth will too. The bad news: it's still uninhabitable.

The planet is a cold super-Jupiter exhibiting a temperature of around 0 degrees Celsius and a wide orbit comparable to that of Neptune around the Sun. This measurement was only possible thanks to JWST's unprecedented imaging capabilities in the thermal infrared. It exemplifies the potential of finding many more such planets similar to Jupiter in mass, temperature, and orbit. Studying them will improve our knowledge of how gas giants form and evolve in time.

WASP-39 b, a giant planet with a diameter 1.3 times greater than Jupiter, but similar mass to Saturn that orbits a star about 700 light-years away from Earth, is tidally locked to its parent star. This means it has a constant dayside and a constant nightside -- one side of the planet is always exposed to its star, while the other is always shrouded in darkness.

The most abundant are the sub-Neptunes, planets between the size of Earth and Neptune. Calculating their density poses a problem for scientists: depending on the method used to measure their mass, two populations are highlighted, the dense and the less dense. Is this due to an observational bias or the physical existence of two distinct populations of sub-Neptunes? Recent work argues for the latter. Thu, 27 Jun 2024 17:22:26 EDT https://www.sciencedaily.com/releases/2024/06/240627172226.htm https://www.sciencedaily.com/releases/2024/06/240613140815.htm The small footprint and dim light of white dwarfs, remnants of stars that have burned through their fuel, may make excellent backdrops for studying planets with enough water to harbor life. The trick is spotting the shadow of a planet against a former star that has withered to a fraction of its size and finding that it's a planet that has kept its water oceans for billions of years even after riding out the star's explosive and violent final throes. A new study of the dynamics of white dwarf systems suggests that, in theory, some watery planets may indeed thread the celestial needles necessary to await discovery and closer scrutiny.

The potentially-habitable planet, named Gliese 12 b, orbits its host star every 12.8 days, is comparable in size to Venus -- so slightly smaller than Earth -- and has an estimated surface temperature of 42 C (107 F), which is lower than most of the 5,000-odd exoplanets confirmed so far. That is assuming it has no atmosphere, however, which is the crucial next step to establishing if it is habitable.

This ultra-hot giant is characterized by an asymmetry between the amount of light observed on its eastern terminator -- the fictitious line that separates its night side from its day side -- and that observed on its western terminator. This peculiarity is thought to be due to a 'glory', a luminous phenomenon similar to a rainbow, which occurs if the light from the star -- the 'sun' around which the exoplanet orbits -- is reflected by clouds made up of a perfectly uniform substance. If this hypothesis is confirmed, this would be the first detection of this phenomenon outside our solar system.

But for a complete understanding of planet formation, we also need to study examples where planet formation has not yet started. Looking for something and not finding it can be even more difficult than finding it sometimes, but new detailed observations of the young star DG Taurus show that it has a smooth protoplanetary disk without signs of planet formation. This successful non-detection of planet formation may indicate that DG Taurus is on the eve of planet formation.

Three-dimensional (3D) simulations helped model the flow of the planet's atmosphere. The scientists hope to widen their planet-observing net and survey 20 additional star systems to find more planets losing their atmosphere and learn about their evolution.

These long period large exoplanets orbit a K dwarf star and belong to a class of planets known as warm Jupiters, which have orbital periods of 10-200 days and are at least six times Earth's radius. This recent discovery offers exciting research opportunities for the future of finding long-period planets that resemble those in our own solar system.

It is so close to its parent star that it experiences a consistent, torrential blast of energy, which evaporates its hydrogen atmosphere -- causing it to puff off the planet.

The team compared the early collision histories of the two bodies and determined that Venus likely experienced higher-speed, higher-energy impacts creating a super-heated core that promoted extended volcanism and resurfaced the planet.
