The James Webb Space Telescope (JWST) has observed the atmosphere of the exoplanet WASP-107b. The planet is about the size of Jupiter but has a low density, similar to Neptune. Because of this, astronomers have called it a “cotton candy” or “super puff” planet
The JWST’s Mid-Infrared Instrument (MIRI) has revealed that WASP-107b has a dynamic atmosphere made up of:
- Water vapor
- Sulfur dioxide
- Silicate sand clouds
The planet’s low density and thin atmosphere allowed astronomers to peer deeper into the atmosphere than usual. The discovery of these clouds is a milestone that could change our understanding of planetary formation and evolution.
A team of astronomers have recently used the Mid-Infrared Instrument (MIRI) on board JWST to explore WASP107b (the second planet in orbit around WASP107) which, because of its thin fluffy atmosphere, enabled them to peer further and deeper than usual revealing new atmospheric details
Yes, the James Webb Space Telescope (JWST) can study the atmospheres of exoplanets. One of the JWST’s main uses is to search for the building blocks of life in other parts of the universe.
The JWST has also observed:
- WASP-39b The JWST’s observations of this exoplanet showed the presence of carbon dioxide, carbon monoxide, potassium, sodium, sulfur dioxide, and water in its atmosphere.
- K2-18 b The JWST’s observations of this exoplanet showed the presence of carbon dioxide and methane in its atmosphere.
- Distant rocky planet The JWST observed water vapor around this planet, which could indicate the presence of an atmosphere.
The James Webb Space Telescope (JWST) also observed the exoplanet WASP-96b. The JWST’s spectrum of WASP-96b confirmed the presence of water vapor and evidence of clouds and hazes. This was the first time the JWST had provided precise details of the contents of an atmosphere on a world beyond our solar system.
WASP-107b is a gaseous exoplanet that orbits the star WASP-107. It’s located in the constellation Virgo, about 200 light-years from Earth
Here are some facts about WASP-107b:
- Size: It’s about the size of Jupiter, but has only 12% of Jupiter’s mass.
- Density: It’s one of the lowest density planets known.
- Orbit: It takes 5.7 days to orbit its star.
- Atmosphere: It has a fluffy atmosphere with sand clouds.
- Temperature: It has temperatures around 500 degrees Celsius.
WASP-107b was discovered in 2017 by a team led by D. R. Anderson. It’s been described as a “cotton candy” planet and a “super puff
WASP-107b is one of the hottest known exoplanets. Its temperature is around 500°C (932°F).
Here are some other exoplanet temperatures:
- WASP-17 b: 1,500°C (2,700°F)
- WASP-12 b: 2,210°C (4,000°F)
- WASP-39 b: 900°C (1,600°F)
WASP-107b is about 200 light-yearsaway from Earth. It’s located in the constellation Virgo.
WASP-107b orbits a K-type main sequence star that’s slightly cooler and less massive than our sun. The star is about 200 light-years from Earth
