Finding Atmospheres on Red Dwarf Planets Will Take Hundreds of Hours of Webb Time

Summary by Ground News

New research suggests that it could take the capable JWST hundreds of hours of observing time to detect these atmospheres to a greater degree of certainty. Red dwarfs are known for their powerful flaring, and in some cases, the flares are powerful enough to render nearby planets uninhabitable. All that stellar activity can make it harder to study exoplanet atmospheres spectroscopically.

Finding Atmospheres on Red Dwarf Planets Will Take Hundreds of Hours of Webb Time

The JWST is enormously powerful. One of the reasons it was launched is to examine exoplanet atmospheres to determine their chemistry, something only a powerful telescope can do. But even the JWST needs time to wield that power effectively, especially when it comes to one of exoplanet science’s most important targets: rocky worlds orbiting red dwarfs. Red dwarfs are the most common type of star in the Milky Way. Observations show that red dwarfs…
