The Daily Galaxy on MSNAstronomers Just Found the Fastest Winds Ever Recorded – And They’re on Another PlanetAstronomers have just made an extraordinary discovery on the exoplanet WASP-127b: winds reaching a staggering 20,500 miles ...
The hunt for potentially habitable rocky planets in our galaxy has been the holy grail of exoplanet studies for decades.
Astronomical discovery: supersonic gales of 20,500 mph batter the exoplanet WASP-127b, breaking cosmic records for ...
A transmission spectrum is made by comparing starlight filtered through a planet’s atmosphere as it moves in front of the star to the unfiltered starlight detected when the planet is beside the ...
This graphic shows the transmission spectrum obtained by Webb observations of rocky exoplanet GJ 486 b. The science team’s analysis shows hints of water vapor; however, computer models show that ...
Atmospheric Reconnaissance of TRAPPIST-1 b with JWST/NIRISS: Evidence for Strong Stellar Contamination in the Transmission Spectra.
The team obtained transmission spectra during four transits of WASP-39b, using three different instruments on JWST: NIRSpec (in two different observing modes), NIRISS, and NIRCam. This yielded ...
From the transmission spectra, we are able to decisively rule out prominent absorption by TiO in the exoplanet’s atmosphere.
‘Their surface is not homogeneous, and this inhomogeneity can pollute the transmission spectrum of transiting planets and mimic atmospheric characteristics.’ ...
The absorption spectrum is consistent with both a dense “steam” atmosphere made up of 70 percent water, as well as a cloudy hydrogen atmosphere where the clouds would hide the absorption spectra.
