Hubble reveals another super-Earth, where it’s hot enough to cook a pizza

An artist’s rendering of the warm exoplanet WASP-80 b whose color may appear bluish to human eyes due to the lack of high-altitude clouds and the presence of atmospheric methane identified by NASA’s James Webb Space Telescope, similar to the planets Uranus and Neptune in our own solar system.

Blue-green Uranus may not look like much through a telescope, but you can see its small disk at magnifications of 100x and more. Even this close-up look from the Voyager 2 spacecraft fails to reveal much detail. Credit: NASA/JPL.

The Kármán Line: Where space begins

Light from 23 distant galaxies, identified with red rectangles in the Hubble Space Telescope image at the top, were combined to capture incredibly faint emission from eight different elements, which are labelled in the JWST spectrum at the bottom. Although scientists regularly find these elements on Earth, astronomers rarely, if ever, observe many of them in distant galaxies. Credit: Aaron M. Geller, Northwestern, CIERA + IT-RCDS
