The Webb gets a good closer look at an exoplanet

Exoplanets are hard to spot but the James Webb Space Telescope got an image of one (HIP 65426b), reported September 1: The planet is more than 10,000 times fainter than its host star and about 100 times farther from it than Earth is from the Sun (~93 million miles), so it easily could be spotted when the telescope’s coronagraphs removed the starlight. The exoplanet is between six and 12 times the mass of Jupiter—a range that could be narrowed once the data in these images is analyzed. The planet is only 15 million to 20 million years old, making it very young compared to our 4.5-billion-year-old Earth.
