Using NASA’s planet-hunting spacecraft TESS (Transiting Exoplanet Survey Satellite), astronomers have discovered three Earth-size worlds orbiting around twin stars. It has previously been theorized that binary systems are hostile to the formation of complex planetary arrangements, meaning this discovery could change how we think about planet formation and the stability of worlds after formation. What makes the planets of TOI-2267 …

A Hidden Earth-Size World Could Lurk Far Closer Than ‘Planet Nine’
A newly discovered warp in the outer Solar System may have been created by a small, rocky world, much closer to the Sun than the hypothesized Planet Nine. According to a new measurement of the Kuiper Belt plane – the vast ring of icy worlds wherein Pluto resides – an unexpected 15-degree tilt in the orbital alignment of some objects …

New research using the powerful JWST telescope has identified a planet 41 light-years away which may have an atmosphere. The planet is within the “habitable zone”, the region around a star where temperatures make it possible for liquid water to exist on the surface of a rocky world. This is important because water is a key ingredient that supports the …

This article was originally published at The Conversation. The publication contributed the article to Space.com’s Expert Voices: Op-Ed & Insights. The sun will someday die. This will happen when it runs out of hydrogen fuel in its core and can no longer produce energy through nuclear fusion as it does now. The death of the sun is often thought of …
