HD 80606 b (Artist’s Concept)
·
NASA/ESA/CSA/STScI
This artist’s concept imagines exoplanet HD 80606 b orbiting its Sun-like star. During recent observations by NASA’s James Webb Space Telescope, the planet was near periastron, the point in its orbit when it passes closest to the star. As HD 80606 b approached periastron, its temperature jumped 1,100 degrees Fahrenheit, causing environmental changes that scientists are still analyzing.
