taken on July 25 by the Transiting Exoplanet Survey Satellite. The angular extent of the widest field of view is six degrees. Visible in the images are the comet C/2018 N1, asteroids, variable stars, asteroids and reflected light from Mars. TESS is expected to find thousands of planets around other nearby stars.

This is an artist's impression of the Jupiter-size extrasolar planet, HD 189733b, being eclipsed by its parent star. Astronomers using the Hubble Space Telescope have measured carbon dioxide and carbon monoxide in the planet's atmosphere. The planet is a "hot Jupiter," which is so close to its star that it completes an orbit in only 2.2 days. The planet is too hot for life as we know it. But under the right conditions, on a more Earth-like world, carbon dioxide can indicate the presence of extraterrestrial life. This observation demonstrates that chemical biotracers can be detected by space telescope observations. Credits: ESA, NASA, M. Kornmesser (ESA/Hubble), and STScI

This artist’s illustration shows what the sky might look like from a planet in a particularly dusty solar system. Dust that orbits a star in the plane of the solar system is called zodiacal dust, and the light reflected and scattered by that dust is called zodiacal light. The Hunt for Observable Signatures of Terrestrial Systems, or HOSTS, survey was tasked with learning more about the effect of zodiacal dust on the search for new worlds, to help guide the design of future planet-hunting missions.
