Astronomers discover a new Earth-sized world just 40 light years away – Sky & Telescope

Artist's illustration of a rocky planet with a reasonable atmosphere orbiting a red dwarf star.NASA / JPL-Caltech / R. Hurt (Caltech-IPAC) In searching for planets around other stars, astronomers often look for worlds that most closely resemble our own. The discovery of Gliese 12b, the closest transiting, temperate, Earth-sized planet found to date, promises possibilities

New exoplanet catalog reveals 126 exotic worlds

The new NASA exoplanet The catalog contains 126 newly discovered worlds of a wide variety. It will help astronomers learn more about how exoplanets form and evolve. The catalog will also help them compare exoplanets with planets in our own solar system. Image via WM Keck Observatory/ Adam Makarenko/ University of California, Riverside. A new

Hubble reveals a possible world of water vapor: sky and telescopes

GJ 9827d, depicted in this artist's concept as the blue world at the top, is a candidate “water world” 100 light years from Earth. It is close enough to its star that the “water” in this case is vapor rather than oceans.NASA/ Hubblesite/ ESA/ Leah Hustak (STScI)/ Ralf Crawford (STScI) New Hubble Space Telescope observations

Candidate planet could be incandescent with lava flows: sky and telescope

Artistic illustration of a lava world. ESO / L. Calçada An international team of astronomers has just found signs of an extreme exoplanet that, if it exists, is packed with so many active volcanoes that its temperature rivals that of some stars. TOI-6713.01 appears to be about the size of Earth, only 30% larger than
