Eggshell Planets Have a Thin Brittle Crust With No Tectonics – Unlikely To Be Habitable
Planets without plate tectonics are unlikely to be habitable. But currently, we’ve never seen the surface of an exoplanet to determine if plate tectonics are…

An international team of researchers has discovered a new planet, GJ 367 b, whose surface temperature may reach 1,500 degrees Centigrade – hot enough to…
The boiling new world, which zips around its star at ultraclose range, is among the lightest exoplanets found to date. Ultra-short-period planets are small, compact…
Strange ‘eggshell planets’ are among the rich variety of exoplanets possible, according to a study from Washington University in St. Louis. These rocky worlds have…
Mercury is the speed champion in our Solar System. It orbits the Sun every 88 days, and its average speed is 47 km/s. Its average…
A newly discovered “ultrahot Jupiter” has the shortest orbit of any known gas giant. The hunt for planets beyond our solar system has turned up…
Findings also include a distinctive planetary system with two gas giants. University of California, Los Angeles (UCLA) astronomers have identified 366 new exoplanets, thanks in…
Fragile orbits of seven exoplanets limit late arrival of water. Seven Earth-sized planets orbit the star TRAPPIST-1 in near-perfect harmony, and U.S. and European researchers…
Scientists have added a whopping 301 newly confirmed exoplanets to the total exoplanet tally. Scientists recently added a whopping 301 newly validated exoplanets to the…
The internal compositions of rocky exoplanets correlate with that of their host stars, according to a new study, but not 1:1. This suggests that planet…
Could life survive around the nearest stars? In collaboration with the Breakthrough Initiative, Saber Astronautics, and NASA’s Jet Propulsion Laboratory, Professor Peter Tuthill is leading…
NASA’s James Webb Space Telescope Primed to Lift the Haze Surrounding Sub-Neptunes Detailed atmospheric studies will provide key insights into some of the most common…
A new technique developed in part by University of Hawaiʻi astronomer Nader Haghighipour has allowed scientists to quickly detect a transiting exoplanet with two suns….
Using ESA’s XMM-Newton and NASA’s Chandra X-ray space telescopes, astronomers have made an important step in the quest to find a planet outside of the…
Humans have long speculated on the existence of other worlds, with the idea first mooted by the Ancient Greek philosophers and recurring through the Middle…
By implementing artificial intelligence techniques similar to those used in autonomous cars, a team from the UNIGE and the UniBE, in partnership with the company…
NRAO project ranked as important new initiative. The Astronomy and Astrophysics Decadal Survey (Astro2020) of the U.S. National Academy of Sciences has published its report…
A new astrogeology study suggests that most nearby rocky exoplanets are quite unlike anything in our Solar System. An astronomer from NSF’s NOIRLab has teamed…
