For the first time, astronomers have taken a direct look at an exoplanets insides.An exoplanet about 800 light-years away is spilling its guts into space, and new observations with the James Webb Space Telescope, or JWST, have let astronomers read the entrails, astronomers report this week at a meeting of the American Astronomical Society.If this is true, its super cool, says astronomer Mercedez Lpez-Morales of the Space Telescope Science Institute in Baltimore, who was not involved in the new work.
