This is an artist’s impression of the exoplanet WASP-189 b orbiting its host star. The star appears to glow blue because it is more than 2,000 degrees warmer than our sun. The planet, which is slightly larger than Jupiter, has an inclined orbit around the star̵

Conceptual image by an artist of the surface of the exoplanet TRAPPIST-1f. Of the seven exoplanets discovered orbiting the ultracool dwarf star TRAPPIST-1, this may be the most suitable for life. It’s similar in size to Earth, it’s a little colder than Earth’s temperature, and it’s in the star’s habitable zone, meaning liquid water (and even oceans) could be on the surface. The proximity of the star gives the sky a salmon hue and the other planets are so close that they appear in the sky, just like our moon.
